Abstract:
Although techniques for determining the positions of workers and products and displaying their tracks on a two-dimensional layout were available in the past, they were inconvenient in that work times and process shifts over time could not be grasped. A technique for grasping work contents of a worker highly accurately utilizing electronic tags was also available. However, it was also inconvenient in that the workers had to read the electronic tags intentionally while at work. The work information processor ( 100 ) is capable of showing passage of time and process shifts by specifying steps at given points in time by a position sensor ( 161 ) attached to a worker. Also represented is a work information processor that stores work content definition information for specifying work contents based on the information detected by the sensor and displays work contents along the passage of time, specifies work contents based on values detected by multiple sensors and the times of said detections according to work content definition information, and specifies work contents according to pieces of work content definition information.

       SUMMARY OF INVENTION 
     Technical Problem 
       [0005]    As a first problem, the technology disclosed in the above-mentioned Patent Literature 1 is inconvenient in that a change of a process step with respect to a change in time instant or a time taken for a work cannot be figured out from information displayed on a two-dimensional layout. 
         [0006]    Further, as a second problem, the technology disclosed in the above-mentioned Patent Literature 2 is inconvenient in that a worker must consciously work on reading an RFID tag while at work even though a work content can be figured out with high accuracy. 
         [0007]    Therefore, as a countermeasure against the above-mentioned first problem, the present invention has an object to provide a technology that can indicate the change of the process step with respect to the change in time instant. 
         [0008]    Further, as a countermeasure against the above-mentioned second problem, the present invention has an object to provide a technology that allows the worker&#39;s work content to be identified and presented with high accuracy without forcing an extra operation on the worker. 
       Solution to Problem 
       [0009]    In order to solve the above-mentioned first problem, with a technology that processes work information according to the present invention, process steps on a time-by-time basis are identified from detection values obtained on a time-by-time basis from a sensor attached to a worker or the like by using stored process step information, and a relationship between the time instant and the process step is displayed. 
         [0010]    For example, a work information processing apparatus comprises: a storage unit which stores process-step definition information including a position and a process step associated with the position; and a control unit, wherein the control unit is configured to: receive a detection value that indicates a position detected by a sensor attached to a sensing target and information that determines a time instant at which the detection value is detected, as detected information; determine the process step associated with the position indicated by the detection value from the process-step definition information; and display a change of the process step in which the sensing target exists, according to the detected time instants in coordinates having at least the process step as an axis thereof. 
         [0011]    Further, in order to solve the above-mentioned second problem, work contents on a time-by-time basis are identified by using information that determines a work from detection values obtained on a time-by-time basis from the sensor attached to the worker or the like, and a relationship between the time instant and the work content is displayed. 
         [0012]    For example, a work information processing apparatus comprises: a storage unit which stores work content definition information obtained by associating information determining a detection value sensed by a sensor with a work content; and a control unit, wherein the control unit is configured to: receive a detection value detected by a sensor attached to a first sensing target, information that determines a time instant at which the detection value of the first sensing target is detected, a detection value detected by a sensor attached to a second sensing target, and information that determines a time instant at which the detection value of the second sensing target is detected; determine the work content based on the detection value detected by the sensor attached to the first sensing target and the detection value detected by the sensor attached to the second sensing target according to the work content definition information; and display the determined work content according to information that determines the detected time instant. 
       Advantageous Effects of Invention 
       [0013]    It is possible to provide a technology that presents the change of the process step with respect to the change in time instant. Further, it is possible to provide a technology that allows the worker&#39;s work content to be identified and presented with high accuracy without forcing an extra operation on the worker.

     DESCRIPTION OF EMBODIMENTS 
       [0055]    Hereinafter, embodiments from a first embodiment to a fifth embodiment are described. 
         [0056]      FIG. 1  is a diagram illustrating a work information processing system  1000  according to an embodiment of the present invention. The work information processing system  1000  includes a sensor  161  and a sensed information processing apparatus  100 . 
         [0057]    The sensor  161  is a sensor which detects a position of a person to which the sensor  161  is attached. In this embodiment, the sensor  161  is a position sensor which measures the position of the person within a work region on a plane (two dimensions of an X-coordinate and a Y-coordinate). For example, the sensor  161  is a sensor which acquires information on a latitude/longitude, such as a global positioning system (GPS). 
         [0058]    It should be noted that the sensor  161  is not limited to the position sensor and may be of any kind as long as the sensor  161  can detect the position of a worker or the like. For example, the position of the person to which the sensor  161  is attached may be detected by using a plurality of antennas to receive a radio wave transmitted by a radio wave transmitter attached to a target worker and detecting the position from a radio field intensity. 
         [0059]    Further, the sensor  161  transmits a detection value to the sensed information processing apparatus  100  via radio. 
         [0060]    It should be noted that in  FIG. 1 , the sensor  161  is attached to the worker&#39;s left hand, but the present invention is not limited to such a mode, and any mode can be employed as long as the position of the worker or a work target item (product) can be detected. 
         [0061]    The sensed information processing apparatus  100  receives the detection value transmitted from the sensor  161  by an antenna  150 . 
         [0062]      FIG. 2  is a schematic diagram of the sensed information processing apparatus  100 . 
         [0063]    As illustrated in the figure, the sensed information processing apparatus  100  includes a storage unit  120 , a control unit  130 , an input unit  141 , an output unit  142 , and a communication unit  143 . 
         [0064]    The storage unit  120  includes a sensed information storage area  121 , a process-step definition information storage area  122 , a regional information storage area  123 , and an output information storage area  124 . 
         [0065]    Stored in the sensed information storage area  121  is a sensed information table  200  for storing sensed information. 
         [0066]      FIG. 3  illustrates a structure example of the sensed information table  200 . 
         [0067]    The sensed information table  200  includes a time field  201 , an ID field  202 , an X-coordinate field  203 , and a Y-coordinate field  204 . 
         [0068]    The time field  201  stores information that determines a time instant at which the detection value detected by the sensor  161  is detected. In this embodiment, information that determines a time instant at which the detection value detected by the sensor  161  is received is stored. 
         [0069]    It should be noted that by setting the detection value to be periodically transmitted from the sensor  161  and managing a specific time instant so as to correspond to the value stored in the time field  201  in the sensed information processing apparatus  100 , it is possible to determine the time instant of each record. For example, “1”, “2”, “3”, . . . , and “n” correspond to the detection values “after 1 second”, “after 2 seconds”, . . . , and “after n seconds” from the start of recording, respectively. 
         [0070]    The ID field  202  stores information that determines an ID being identification information for identifying the worker or a work target product to which the sensor  161  is attached. 
         [0071]    In this embodiment, one ID is assigned to the sensor  161  attached to one worker or one product. 
         [0072]    The X-coordinate field  203  stores a value regarding the X-coordinate of the detection value detected by the sensor  161  determined by the ID field  202 . 
         [0073]    The Y-coordinate field  204  stores a value regarding the Y-coordinate of the detection value detected by the sensor  161  determined by the ID field  202 . 
         [0074]    It should be noted that by attaching a sensor ID being identification information uniquely assigned to each sensor to the detection value transmitted from the sensor  161 , the sensed information processing apparatus  100  can manage the ID corresponding to the sensor ID and store the detection value detected by the sensor  161  in the corresponding X-coordinate field  203  and Y-coordinate field  204 . 
         [0075]    Stored in the process-step definition information storage area  122  is a process-step definition table  300  for storing information that defines a process step. 
         [0076]    As a precondition for describing the process-step definition table  300 ,  FIG. 4  is referenced to describe a physical arrangement of a workplace  2 . 
         [0077]      FIG. 4  is a diagram illustrating a two-dimensional layout of the workplace  2 . 
         [0078]    The workplace  2  includes a parts carry-in entrance and a product delivery exit, which are provided to one wall surface, and a first process-step work region  211 , a first in-process item storage space  212 , a second process-step work region  221 , a second in-process item storage space  222 , a third process-step work region  231 , a third in-process item storage space  232 , a fourth process-step work region  241 , a fourth in-process item storage space  242 , a fifth process-step work region  251 , a fifth in-process item storage space  252 , a sixth process-step work region  261 , a sixth in-process item storage space  262 , a seventh process-step work region  271 , a seventh in-process item storage space  272 , and an eighth process-step work region  281 , which are provided to a floor surface. 
         [0079]    Parts of the product carried in from the parts carry-in entrance of the workplace  2  become work targets of a first process step in the first process-step work region  211 . When the work of the first process step is finished, the parts are accumulated in the first process-step in-process item storage space, and when a second process step is started, the parts are passed over to the second process-step work region to become work targets of the second process step. 
         [0080]    In the above-mentioned manner, over the process steps from the first process step to an eighth process step, the parts are assembled to a product to be shipped from the product delivery exit. 
         [0081]    Further, as illustrated in  FIG. 4 , the position on the workplace  2  can be expressed by a coordinate system having two axes, that is, an X-axis and a Y-axis orthogonal to the X-axis, with a predetermined position as an origin point. 
         [0082]    In this embodiment, the X-axis is set to have a direction extending from the first process-step work region  211  to the third process-step in-process item storage space  231  along the wall surface in the long-side direction of the workplace  2 , and the Y-axis is set to have a direction extending from the fourth process-step work region  241  to the fifth process-step work region  251  along the wall surface in the short-side direction of the workplace  2 , with their origin at the position of a corner of the workplace  2  to which the parts carry-in entrance is provided. 
         [0083]    The respective work regions from the first process-step work region  211  to the third in-process item storage space  232  are arranged toward the positive direction of the X-axis along the wall surface in one long-side direction of the workplace  2 , the respective work regions from the fourth process-step work region to the fourth in-process item storage space  242  are arranged toward the positive direction of the Y-axis along the wall surface in the short-side direction of the workplace  2  which is opposed to the wall surface provided with the parts carry-in entrance, and the respective work regions from the fifth process-step work region  251  to the eighth process-step work region  281  are arranged toward the negative direction of the X-axis along the wall surface in the other long-side direction of the workplace  2 . 
         [0084]    In the above-mentioned manner, the parts carried in from the parts carry-in entrance are assembled as the product along a U-shaped flow line via the respective process steps, and carried out from a product carry-out exit. 
         [0085]      FIG. 5  illustrates a structure example of the process-step definition table  300 . 
         [0086]    The process-step definition table  300  includes a process-step ID field  301 , a process-step sequence field  302 , a process-step name field  303 , a standard lead time (LT) field  304 , an indication X-coordinate field  305 , and a work process step description field  306 . 
         [0087]    The process-step ID field  301  stores a process-step ID being information that identifies the process step. 
         [0088]    The process-step sequence field  302  stores information that determines a sequence for carrying out the process step. Examples thereof include continuous numerical values without an overlap such as “1”, “2”, . . . , and “n (n is a natural number equal to or larger than 1)”, and the sequence of the process step being “1” indicates that the process step is carried out in the first place. 
         [0089]    The process-step name field  303  stores an alias that identifies the process step. 
         [0090]    The standard LT field  304  stores a standard required time required to carry out the process step. 
         [0091]    The indication X-coordinate field  305  stores information regarding a coordinate used to indicate the position or the like of the product or the worker on a display screen such as a display screen  550  described later. 
         [0092]    It should be noted that the coordinate stored in the indication X-coordinate field  305  is such a value as to become larger as the product advances along the process steps sequentially. 
         [0093]    Stored in the work process step description field  306  is information indicating contents of each of the process steps. 
         [0094]    Stored in the regional information storage area  123  is a region table  450  for determining a physical region corresponding to the process step. 
         [0095]    It should be noted that as a precondition, in this embodiment, the process step refers to a unit serving as a measure of management of the work. Further, the place/region in which the process step is carried out and the process step have a fixed correlation therebetween. Therefore, in principle, in the workplace  2 , the same process step is not carried out in different places, and one process step that is carried out is always determined by the position of the worker or the product of the work target. 
         [0096]      FIG. 6(   a ) is a diagram illustrating in detail the partial arrangement of the first process-step work region  211 , the first in-process item storage space  212 , the second process-step work region  221 , and the second in-process item storage space  222  of the workplace  2  illustrated in  FIG. 4 . 
         [0097]    A K01 region  410 , a K02 region  420 , a K03 region  430 , and a K04 region  440  of  FIG. 6(   a ) correspond to the first process-step work region  211 , the first in-process item storage space  212 , the second process-step work region  221 , and the second in-process item storage space  222 , respectively, of the workplace  2  illustrated in  FIG. 4 . 
         [0098]    The K01 region includes a first region and a second region. 
         [0099]    The first region is a region surrounded by a point  411  expressed by the X-coordinate being 0 and the Y-coordinate being 0 (hereinafter, referred to as “(0,0)”), a point  412  expressed by (25000,15000), a point  413  expressed by (0,15000), and a point  421  expressed by (25000,0). 
         [0100]    The second region is a region surrounded by the point  413  expressed by (0,15000), a point expressed by (0,17000), a point  414  expressed by (5000,17000), and a point expressed by (5000,15000). 
         [0101]    The K02 region is a region surrounded by the point  421  expressed by (25000,0), a point  422  expressed by (28000,15000), the point  412  expressed by (25000,15000), and a point  431  expressed by (28000,0). 
         [0102]    The K03 region is a region surrounded by the point  431  expressed by (28000,0), a point  432  expressed by (58000,15000), the point  422  expressed by (28000,15000), and a point  441  expressed by (58000,0). 
         [0103]    The K04 region is a region surrounded by the point  441  expressed by (58000,0), a point  442  expressed by (61000,15000), the point  432  expressed by (58000,15000), and a point expressed by (61000,0). 
         [0104]    Based on such an arrangement as illustrated in  FIG. 6A ,  FIG. 6B  illustrates the region table  450  that stores information that defines an area of each of the regions by coordinates of two vertices connected by a diagonal line of each of the regions. 
         [0105]    The region table  450  includes a region ID field  451 , a start X-coordinate field  452 , a start Y-coordinate field  453 , an end X-coordinate field  454 , an end Y-coordinate field  455 , and a corresponding process-step ID field  456 . 
         [0106]    The region ID field  451  stores the region ID as information that identifies the region. 
         [0107]    The start X-coordinate field  452  stores information regarding the X-coordinate of a first vertex being one vertex of two vertices that are opposed to each other across a diagonal line of the region. 
         [0108]    The start Y-coordinate field  453  stores information regarding the Y-coordinate of the first vertex. 
         [0109]    The end X-coordinate field  454  stores information regarding the X-coordinate of a second vertex opposed to the first vertex across the diagonal line. 
         [0110]    The end Y-coordinate field  455  stores information regarding the Y-coordinate the second vertex. 
         [0111]    The corresponding process-step ID field  456  stores the process-step ID of the process step carried out in the region determined by the value stored in the region ID field  451 . 
         [0112]    Stored in the output information storage area  124  is an output information table  500  for storing information to be output. 
         [0113]      FIG. 7  illustrates a structure example of the output information table  500 . 
         [0114]    The output information table  500  includes a time field  501 , an ID field  502 , a process step field  503 , and an output coordinate field  504 . 
         [0115]    The time field  501  stores information that determines a time instant at which the detection value detected by the sensor  161  is detected. In this embodiment, information that determines a time instant at which the detection value detected by the sensor  161  is received is stored. 
         [0116]    The ID field  502  stores information that determines an ID being identification information for identifying the worker or the work target product to which the sensor  161  is attached. 
         [0117]    The process step field  503  stores information that determines a process step determined based on the position of the worker or the work target product to which the sensor  161  is attached. 
         [0118]    The output coordinate field  504  stores information that determines an output coordinate used when the position of the worker or the work target product to which the sensor  161  is attached is displayed on a screen. 
         [0119]      FIG. 2  is referenced again for the description. 
         [0120]    The control unit  130  includes an input information reception module  131 , an output information generation module  132 , a sensed information management module  133 , and a sensed information analysis module  134 . 
         [0121]    The input information reception module  131  receives information input through the input unit  141  described later. 
         [0122]    The output information generation module  132  forms an output screen by combining information to be output and a screen layout, and makes the output unit  142  described later to display the output screen. 
         [0123]    The sensed information management module  133  performs a processing which stores the detection value received from each of the sensors  161  via the communication unit  143  described later in the sensed information table  200 . 
         [0124]    It should be noted that the sensed information management module  133  stores a correlation between the sensor ID of the sensor  161  and the ID for identifying the worker, and stores an ID corresponding to the sensor ID attached to a measured value received from the sensor  161  in the ID field  202  of the sensed information table  200 . 
         [0125]    Further, the sensed information management module  133  stores the time instant at which the measured value is received in a region (not shown) of the storage unit  120 . 
         [0126]    The sensed information analysis module  134  uses the information stored in the sensed information table  200  to determine which process step a target to which the sensor  161  is attached is in for each of the sensors  161 . 
         [0127]    Specifically, the sensed information analysis module  134  determines the X-coordinate and the Y-coordinate from the detection value detected from the sensor  161 . 
         [0128]    Then, from among records stored in the region table  450 , the sensed information analysis module  134  determines the record in which the determined X-coordinate exists between the value of the start X-coordinate field  452  and the value of the end X-coordinate field  454  and in which the determined Y-coordinate exists between the value of the start Y-coordinate field  453  and the value of the end Y-coordinate field  455 . 
         [0129]    Then, the sensed information analysis module  134  determines the process-step ID stored in the corresponding process-step ID field  456  of the determined record. 
         [0130]    Then, from among records stored in the process-step definition table  300 , the sensed information analysis module  134  determines the values of the process-step name field  303  and the indication X-coordinate field  305  of the record having the determined process-step ID which matches the value of the process-step ID field  301  within the process-step definition table  300 . 
         [0131]    Then, the sensed information analysis module  134  stores information on the determined process step and information on the output coordinate in the process step field  503  and the output coordinate field  504 , respectively, of the output information table  500 . 
         [0132]    The input unit  141  receives an input of information from an operator. 
         [0133]    The output unit  142  outputs information. 
         [0134]    The communication unit  143  performs transmission/reception of information through the antenna  150 . 
         [0135]      FIG. 8  is a diagram illustrating a hardware configuration of the sensed information processing apparatus  100  according to this embodiment. 
         [0136]    In this embodiment, the sensed information processing apparatus  100  is a computer such as a client PC (personal computer), a workstation, a server device, each of various mobile phone terminals, or a personal digital assistant (PDA). 
         [0137]    The sensed information processing apparatus  100  includes an input device  111 , an output device  112 , an arithmetic operation device  113 , a main memory device  114 , an external storage device  115 , a communication device  116 , and a bus  117  that connects the respective devices. 
         [0138]    The input device  111  is a device which receives an input such as a keyboard, a mouse, a touch pen, or other such pointing devices. 
         [0139]    The output device  112  is a device which performs displaying such as a display. 
         [0140]    The arithmetic operation device  113  is an arithmetic operation device such as a central processing unit (CPU). 
         [0141]    The main memory device  114  is a memory device such as a random access memory (RAM). 
         [0142]    The external storage device  115  is a nonvolatile storage device such as a hard disk drive or a flash memory. 
         [0143]    The communication device  116  is a communication device which performs radio communications through an antenna, such as a radio communication unit. 
         [0144]    The input information reception module  131 , the output information generation module  132 , the sensed information management module  133 , and the sensed information analysis module  134  of the sensed information processing apparatus  100  are implemented by programs that makes the arithmetic operation device  113  of the sensed information processing apparatus  100  to perform processings. 
         [0145]    The above-mentioned programs, which are stored within the main memory device  114  or the external storage device  115 , are loaded onto the main memory device  114  before execution thereof, and executed by the arithmetic operation device  113 . 
         [0146]    Further, the storage unit  120  of the sensed information processing apparatus  100  is implemented by the main memory device  114  or the external storage device  115  of the sensed information processing apparatus  100 . 
         [0147]    The input unit  141  of the sensed information processing apparatus  100  is implemented by the input device  111  of the sensed information processing apparatus  100 . 
         [0148]    The output unit  142  of the sensed information processing apparatus  100  is implemented by the output device  112  of the sensed information processing apparatus  100 . 
         [0149]    The communication unit  143  of the sensed information processing apparatus  100  is implemented by the communication device  116  of the sensed information processing apparatus  100 . 
         [0150]    Next,  FIG. 9  is referenced to describe a flow of a situation display processing according to this embodiment. 
         [0151]      FIG. 9  is a flowchart illustrating the flow of the situation display processing. 
         [0152]    First, the sensed information management module  133  receives the detection value transmitted from the sensor  161  via the communication unit  143  at predetermined intervals (for example, every one second) (Step S 001 ). 
         [0153]    Specifically, the sensed information management module  133  receives the detection value transmitted from the sensor  161  via the communication unit  143 . 
         [0154]    Subsequently, the sensed information management module  133  stores the detection value received in Step S 001  in the sensed information table  200  (Step S 002 ). 
         [0155]    Subsequently, the sensed information analysis module  134  determines a work process step from sensed information (Step S 003 ). 
         [0156]    Specifically, the sensed information analysis module  134  reads the values of the X-coordinate field  203  and the Y-coordinate field  204  of the sensed information table  200 . 
         [0157]    Then, from among the records stored in the region table  450 , the sensed information analysis module  134  determines a record in which the read X-coordinate exists between the value of the start X-coordinate field  452  and the value of the end X-coordinate field  454  and in which the read Y-coordinate exists between the value of the start Y-coordinate field  453  and the value of the end Y-coordinate field  455 . 
         [0158]    Then, the sensed information analysis module  134  determines the process-step ID stored in the corresponding process-step ID field  456  of the determined record. 
         [0159]    Subsequently, the sensed information analysis module  134  determines the output coordinate from the process-step ID of the work process step determined in Step S 003  (Step S 004 ). 
         [0160]    Specifically, from among the records stored in the process-step definition table  300 , the sensed information analysis module  134  determines the values of the process-step name field  303  and the indication X-coordinate field  305  of a record having the process-step ID determined in Step S 003  matches the value of the process-step ID field  301  within the process-step definition table  300 . 
         [0161]    Then, the sensed information analysis module  134  stores the information on the determined process step and the information on the determined output coordinate in the process step field  503  and the output coordinate field  504 , respectively, of the output information table  500 . 
         [0162]    Subsequently, the output information generation module  132  uses the information within the output information table  500  to form and display a screen (Step S 005 ). 
         [0163]    Specifically, with regard to the records of the output information table  500 , the output information generation module  132  displays points in display positions determined by the output coordinate field  504  in ascending order of the values of the time field  501  for each value of the ID field  502 , to thereby form and display the situation display screen  550  illustrated in  FIG. 10 . 
         [0164]    In this case, when a sensing target moves to a different process step, the output information generation module  132  the sensing target by adding an oblique line connecting the previous point in the process step before the movement to the point after the movement. 
         [0165]      FIG. 10  is a diagram illustrating an example of the situation display screen  550 . 
         [0166]    The situation display screen  550  includes a process-step display field  551 , a time instant axis line  552 , a process-step axis line  553 , a present time instant indicating line  554 , a worker position indicating line  555 , and a product position indicating line  556 . 
         [0167]    The process-step display field  551  includes, along a process step order of the process-step axis line  553 , a first process step field, a first in-process item field, a second process step field, a second in-process item field, a third process step field, a third in-process item field, a fourth process step field, a fourth in-process item field, a fifth process step field, a fifth in-process item field, a sixth process step field, a sixth in-process item field, a seventh process step field, a seventh in-process item field, and an eighth process step field. 
         [0168]    The respective fields of the process-step display field  551  correspond to the first process-step work region  211 , the first in-process item storage space  212 , the second process-step work region  221 , the second in-process item storage space  222 , the third process-step work region  231 , the third in-process item storage space  232 , the fourth process-step work region  241 , the fourth in-process item storage space  242 , the fifth process-step work region  251 , the fifth in-process item storage space  252 , the sixth process-step work region  261 , the sixth in-process item storage space  262 , the seventh process-step work region  271 , the seventh in-process item storage space  272 , and the eighth process-step work region  281  of the workplace  2 . 
         [0169]    It should be noted that the value of the indication X-coordinate field  305  of the process-step definition table  300  and the value of the output coordinate field  504  of the output information table  500  are values that determine the coordinates around the center of the respective fields of the process-step display field  551 . The output information generation module  132  displays the position of the product and the position of the worker on the display screen such as the display screen  550  at respectively different coordinates so as not to the positions being overlapped. For example, the output information generation module  132  adds/subtracts a predetermined value to/from the value of the output coordinate field  504  of the output information table  500 , to thereby make the display position of the product and the display position of the worker to differ from each other. 
         [0170]    Further, display breadths of the respective fields of the process-step display field  551  may be set according to the lengths of the process steps in terms of the layout. For example, the display breadths may be set wider in proportion to the lengths of the process steps in terms of the layout in a direction toward the subsequent process step. 
         [0171]    Alternatively, the display breadths of the respective fields of the process-step display field  551  may be set to be proportionate to a standard lead time of the process step, or may be simply set as regular intervals. 
         [0172]    The time instant axis line  552 , which serves as a vertical axis directed downward from the top of the situation display screen  550 , indicates a flow of the time instant. 
         [0173]    The process-step axis line  553 , which serves as a horizontal axis directed rightward from the left of the situation display screen  550 , indicates a flow of the work process step. 
         [0174]    The present time instant indicating line  554  indicates a time instant corresponding to the present time instant on the time instant axis line  552 . 
         [0175]    The worker position indicating line  555  is a line that connects points indicating the positions of the sensor  161  on a time-by-time basis attached to the worker. 
         [0176]    The product position indicating line  556  is a line that connects points indicating the positions of the sensor  161  on a time-by-time basis attached to the product of the work target or the like. 
         [0177]    In other words, for example, if the worker of the sensing target or the like exists in the first process-step work region  211 , the situation display screen  550  displays the point in the position corresponding to the detected time instant at the center of the first process step field, and displays the points, which are recorded from the start of detection until the present time instant, as the worker position indicating line  555 . 
         [0178]    Then, the detected information management module  133  returns the processing to Step S 001 , and receives the sensed information. 
         [0179]    The flow of the situation display processing has been described above. 
         [0180]    According to the first embodiment of the present invention, the sensed information processing apparatus  100  can detect the positions of the worker and the product that are the sensing targets, determine the process step and the time instant, and use the situation display screen  550  to present the correspondence between the process step and a passage of time in the form of an at-a-glance chart. 
         [0181]    Next,  FIGS. 11 to 13  are referenced to describe the second embodiment of the present invention. 
         [0182]    A sensed information processing apparatus  100  according to the second embodiment of the present invention is, in principle, the same as the sensed information processing apparatus  100  according to the first embodiment, and hence the following description is directed to different points therebetween. 
         [0183]    In the second embodiment, an output information table stored in the output information storage region  124  of the storage unit  120  is an output information table  600  illustrated in  FIG. 11 . 
         [0184]    The output information table  600  includes an ID field  601 , a process step field  602 , a start time field  603 , an end time field  604 , a situation field  605 , an alert field  606 , and an output coordinate field  607 . 
         [0185]    The ID field  601  stores information that determines the ID being the identification information for identifying the work target product to which the sensor  161  is attached. 
         [0186]    The process step field  602  stores information that determines the process step determined from the position of the work target product to which the sensor  161  is attached. 
         [0187]    The start time field  603  stores information that indicates a time at which the process step within the process step field  602  is started with regard to the product identified by the ID stored in the ID field  601 . 
         [0188]    The end time field  604  stores information that indicates a time at which the process step within the process step field  602  is finished with regard to the product identified by the ID stored in the ID field  601 . 
         [0189]    The situation field  605  stores information that indicates a state of the process step within the process step field  602  with regard to the product identified by the ID stored in the ID field  601 . Examples thereof include “finished” and “being worked”. 
         [0190]    The alert field  606  stores information that indicates whether or not there occurs an event to be alerted after the process step within the process step field  602  is started, with regard to the product identified by the ID stored in the ID field  601 . For example, “present” indicates that the event to be alerted has occurred. 
         [0191]    The output coordinate field  607  stores information that determines the output coordinate used when the position of the work target product to which the sensor  161  is attached is displayed on the screen. 
         [0192]      FIG. 12  illustrates a processing flow of a situation display processing according to the second embodiment. 
         [0193]    First, the sensed information management module  133  receives the detection value transmitted from the sensor  161  via the communication unit  143  at predetermined intervals (for example, every one second) (Step S 101 ). 
         [0194]    Specifically, the sensed information management module  133  receives the detection value transmitted from the sensor  161  via the communication unit  143 . 
         [0195]    Subsequently, the sensed information management module  133  stores the detection value received in Step S 101  in the sensed information table  200  (Step S 102 ). 
         [0196]    Subsequently, the sensed information analysis module  134  determines a work process step from sensed information (Step S 103 ). 
         [0197]    Specifically, the sensed information analysis module  134  reads the values of the X-coordinate field  203  and the Y-coordinate field  204  of the sensed information table  200 . 
         [0198]    Then, from among the records stored in the region table  450 , the sensed information analysis module  134  determines a record in which the read X-coordinate exists between the value of the start X-coordinate field  452  and the value of the end X-coordinate field  454  and in which the read Y-coordinate exists between the value of the start Y-coordinate field  453  and the value of the end Y-coordinate field  455 . 
         [0199]    Then, the sensed information analysis module  134  determines the process-step ID stored in the corresponding process-step ID field  456  of the determined record. 
         [0200]    Subsequently, the sensed information analysis module  134  determines the start time and the end time of the process step determined in Step S 103  for each product of the sensing target (Step S 104 ). 
         [0201]    Specifically, the sensed information analysis module  134  determines a time at which switching of the process step is over for each ID of the product of the sensing target from the sensed information table  200 . 
         [0202]    Then, the sensed information analysis module  134  stores the values of the time field  201 , immediately before and after the process step switching is over, in the end time field  604  and the start time field  603  of the output information table  600  as the end time of the process step before the switching and the start time of the process step after the switching, respectively. 
         [0203]    Subsequently, the sensed information analysis module  134  determines a status of each of the process steps for each product of the sensing target (Step S 105 ). 
         [0204]    Specifically, with regard to the output information table  600 , for each combination between the product of the sensing target and the process step determined in Step S 103 , if the start time field  603  and the end time field  604  each store a value, the sensed information analysis module  134  stores “finished” information indicating that the process step is finished in the situation field  605 . The information called “being worked” indicating that the process step is not finished is stored in the situation field  605  if the start time field  603  stores a value but the end time field  604  does not store a value. 
         [0205]    Subsequently, the sensed information analysis module  134  determines the alert situation of each of the process steps for each product of the sensing target (Step S 106 ). 
         [0206]    Specifically, with regard to the output information table  600 , for each combination between the product of the sensing target and the process step determined in Step S 103 , the sensed information analysis module  134  judges whether or not the event to be alerted occurs between the value of the start time field  603  and the value of the end time field  604  (if the end time is not stored, a value indicating the present time instant), and if the event to be alerted occurs, the information called “present” is stored in the alert field  606 . 
         [0207]    It should be noted that examples of the event to be alerted include a case where a time taken to end the process step exceeds the standard LT field  304  of the process-step definition table  300  in the process step corresponding to the process step determined in Step S 103 . 
         [0208]    Subsequently, the sensed information analysis module  134  determines the output coordinate from the process-step ID of the work process step determined in Step S 103  (Step S 107 ). 
         [0209]    Specifically, from among the records of the process-step definition table  300 , the sensed information analysis module  134  determines the values of the process-step name field  303  and the indication X-coordinate field  305  of a record having the process-step ID determined in Step S 103  matches the value of the process-step ID field  301  of the process-step definition table  300 . 
         [0210]    Then, the sensed information analysis module  134  stores the information on the determined process step and the information on the output coordinate in the process step field  602  and the output coordinate field  607 , respectively, of the output information table  600 . 
         [0211]    Subsequently, the output information generation module  132  uses the information within the output information table  600  to form and display the screen (Step S 108 ). 
         [0212]    Specifically, with regard to the records of the output information table  600 , for each of the values of the ID field  601 , the output information generation module  132  displays a line segment in the display position of the corresponding process step according to a ratio of an elapsed time to the standard lead time of the process step, to thereby form and display a progress display screen  650  illustrated in  FIG. 13 . 
         [0213]      FIG. 13  is a diagram illustrating an example of the progress display screen  650 . 
         [0214]    The progress display screen  650  includes a process-step display field  651 , a product axis line  652 , a process-step axis line  653 , an ID display field  654 , a work requiring time ratio indicating line  655 , and a details indicating field  656 . 
         [0215]    The process-step display field  651  includes, along a process step order of the process-step axis line  653 , a first process step field, a first in-process item field, a second process step field, a second in-process item field, a third process step field, a third in-process item field, a fourth process step field, a fourth in-process item field, a fifth process step field, a fifth in-process item field, a sixth process step field, a sixth in-process item field, a seventh process step field, a seventh in-process item field, and an eighth process step field. 
         [0216]    The respective fields of the process-step display field  651  correspond to the first process-step work region  211 , the first in-process item storage space  212 , the second process-step work region  221 , the second in-process item storage space  222 , the third process-step work region  231 , the third in-process item storage space  232 , the fourth process-step work region  241 , the fourth in-process item storage space  242 , the fifth process-step work region  251 , the fifth in-process item storage space  252 , the sixth process-step work region  261 , the sixth in-process item storage space  262 , the seventh process-step work region  271 , the seventh in-process item storage space  272 , and the eighth process-step work region  281  of the workplace  2 . 
         [0217]    It should be noted that the value of the indication X-coordinate field  305  of the process-step definition table  300  and the value of the output coordinate field  607  of the output information table  600  are values that determine the coordinates around the left edge of the respective fields of the process-step display field  651 . 
         [0218]    Further, display breadths of the respective fields of the process-step display field  651  may be set according to the lengths of the process steps in terms of the layout. For example, the display breadths may be set wider in proportion to the lengths of the process steps in terms of the layout in a direction toward the subsequent process step. 
         [0219]    Alternatively, the display breadths of the respective fields of the process-step display field  651  may be set to be proportionate to a standard lead time of the process step, or may be simply set as regular intervals. 
         [0220]    The product axis line  652 , which serves as a vertical axis directed upward from the bottom of the progress display screen  650 , indicates a flow along which the IDs that identify the products are arrayed in order. 
         [0221]    The process-step axis line  653 , which serves as a horizontal axis directed rightward from the left of the progress display screen  650 , indicates a flow of the work process step. 
         [0222]    The ID display field  654  indicates an ID corresponding to the product on the product axis line  652 . 
         [0223]    The work requiring time ratio indicating line  655  indicates a line that makes the value of a ratio of the required time taken for each of the process steps of the sensor  161  attached to the product to the standard lead time to be displayed as a ratio of the length of the work requiring time ratio indicating line  655  to the width of each of the process step fields. 
         [0224]    It should be noted that the work requiring time ratio indicating line  655  is displayed with the elapsed time until the present time being regarded as a work requiring time with regard to the work being performed. 
         [0225]    The details indicating field  656  is a field that indicates details of information indicated by the work requiring time ratio indicating line  655  as textual information. For example, the details indicating field  656  is a field that indicates a time instant at which each of the process steps is turned on, a work time, and information on a work state or the like. 
         [0226]    According to the progress display screen  650 , for example, if the product of the sensing target exists in the first process-step work region  211  for 90 percent of the standard lead time, the situation display screen  650  displays the work requiring time ratio indicating line  655  having a length of 90 percent of the width of the first process step starting from the left edge of the first process step field, and displays the details indicating field  656  indicating a time/date at which the process step is started, the work time, and the fact of being in the finished state. 
         [0227]    Then, the detected information management module  133  returns the processing to Step S 101 , and receives the sensed information. 
         [0228]    The flow of the situation display processing in the second embodiment has been described above. 
         [0229]    According to the second embodiment of the present invention, the sensed information processing apparatus  100  can detect the position of the product being the sensing target, determine the process step and the time instant, and display the time required to carry out the process step as a ratio thereof to the standard lead time. 
         [0230]    With the above-mentioned configuration, the user of the sensed information processing apparatus  100  can review progress information on the work in the form of an at-a-glance chart. 
         [0231]    Next,  FIGS. 14 to 17  are referenced to describe the third embodiment of the present invention. 
         [0232]    The sensor  161  according to the third embodiment of the present invention has a function of, in addition to the position sensor, an acceleration sensor which detects an acceleration divided into acceleration components of three axes of an X-axis, a Y-axis, and a Z-axis that are orthogonal to one another. 
         [0233]    It should be noted that the three axes of the X-axis, the Y-axis, and the Z-axis with which the sensor  161  detects the acceleration are independent axes irrelevant to the X-coordinate and the Y-coordinate that indicate the position detected by the sensor  161 . 
         [0234]    Further, a sensed information processing apparatus  100  according to the third embodiment of the present invention is, in principle, the same as the sensed information processing apparatus  100  according to the first embodiment, and hence the following description is directed to different points therebetween. 
         [0235]    In the third embodiment, the sensed information table  200  stored in the sensed information storage area  121  of the storage unit  120  is a sensed information table  700  illustrated in  FIG. 14 . 
         [0236]    Further, an output information table stored in the output information storage area  124  is an output information table  750  illustrated in  FIG. 15 . 
         [0237]      FIG. 14  illustrates a structure example of the sensed information table  700  according to the third embodiment. 
         [0238]    The sensed information table  700  includes an X-axis acceleration field  705 , a Y-axis acceleration field  706 , and a Z-axis acceleration field  707  in addition to the respective fields included in the sensed information table  200  according to the first embodiment. 
         [0239]    The X-axis acceleration field  705  stores the magnitude of an X-axis component among accelerations detected by the sensor  161  in units of milli-G ( 1/1000 G). 
         [0240]    The Y-axis acceleration field  706  stores the magnitude of a Y-axis component among the accelerations detected by the sensor  161  in units of milli-G. 
         [0241]    The Z-axis acceleration field  707  stores the magnitude of a Z-axis component among the accelerations detected by the sensor  161  in units of milli-G. 
         [0242]      FIG. 15  illustrates a structure example of the output information table  750  according to the third embodiment. 
         [0243]    The output information table  750  includes a time field  751 , an ID field  752 , a process step field  753 , an output coordinate field  754 , a combined acceleration field  755 , and an alert field  756 . 
         [0244]    The time field  751  stores the information that determines the time instant at which the detection value detected by the sensor  161  is detected. In this embodiment, the information that determines a time instant at which the detection value detected by the sensor  161  is received is stored. 
         [0245]    The ID field  752  stores the information that determines the ID being the identification information for identifying the worker to which the sensor  161  is attached. 
         [0246]    The process step field  753  stores the information that determines the process step determined from the position of the worker to which the sensor  161  is attached. 
         [0247]    The output coordinate field  754  stores the information that determines the output coordinate used when the position of the worker to which the sensor  161  is attached is displayed on the screen. 
         [0248]    The combined acceleration field  755  stores the value of the magnitude of the acceleration obtained by combining the acceleration components of the three axes which have been measured by the sensor  161 . 
         [0249]    The alert field  756  stores the information that indicates whether or not there occurs an event to be alerted after the process step within the process step field  753  is started, with regard to the target identified by the ID stored in the ID field  752 . For example, “present” indicates that the event to be alerted has occurred. 
         [0250]      FIG. 16  illustrates a processing flow of a situation display processing in the third embodiment. 
         [0251]    First, the sensed information management module  133  receives the detection value transmitted from the sensor  161  via the communication unit  143  at predetermined intervals (for example, every one second) (Step S 201 ). 
         [0252]    Specifically, the sensed information management module  133  receives the detection value transmitted from the sensor  161  via the communication unit  143 . 
         [0253]    Subsequently, the sensed information management module  133  stores the detection value received in Step S 101  in the sensed information table  700  (Step S 202 ). 
         [0254]    Subsequently, the sensed information analysis module  134  determines a work process step from sensed information (Step S 203 ). 
         [0255]    Specifically, the sensed information analysis module  134  reads the values of the X-coordinate field  203  and the Y-coordinate field  204  of the sensed information table  700 . 
         [0256]    Then, from among the records stored in the region table  450 , the sensed information analysis module  134  determines a record in which the read X-coordinate exists between the value of the start X-coordinate field  452  and the value of the end X-coordinate field  454  and in which the read Y-coordinate exists between the value of the start Y-coordinate field  453  and the value of the end Y-coordinate field  455 . 
         [0257]    Then, the sensed information analysis module  134  determines the process-step ID stored in the corresponding process-step ID field  456  of the determined record. 
         [0258]    Subsequently, the sensed information analysis module  134  calculates the magnitude of the acceleration obtained by combining the sensed accelerations of the three axes for each worker of the sensing target (Step S 204 ). 
         [0259]    Specifically, the sensed information analysis module  134  calculates the acceleration obtained by combining the sensed accelerations of the three axes for each ID of the worker of the sensing target, and stores the acceleration in the combined acceleration field  755  of the output information table  750 . 
         [0260]    Subsequently, the sensed information analysis module  134  determines the output coordinate for each worker of the sensing target (Step S 205 ). 
         [0261]    Specifically, with regard to the output information table  750 , for each combination between the production worker of the sensing target and the process step determined in Step S 203 , based on the values of the sensed X-coordinate and the sensed Y-coordinate, the sensed information analysis module  134  determines the coordinate on the screen to be displayed by indicating the position of the worker by a distance corresponding to a route from the parts carry-in entrance in the workplace  2 , and stores the coordinate in the output coordinate field  754 . 
         [0262]    For example, if the process step corresponding to the detected position is the process step to be carried out earlier than that of the third in-process item storage space  232 , the sensed information analysis module  134  stores the value of the sensed X-coordinate in the output coordinate field  754  as it is. 
         [0263]    Alternatively, if the process step corresponding to the detected position is that of the fourth process-step work region  241  or the fourth in-process item storage space  242 , the sensed information analysis module  134  stores a value obtained by adding the value of the sensed Y-coordinate to the value of the X-coordinate regarding any of the points on a line in which the third in-process item storage space  232  contacts with the fourth process-step work region  241 , in the output coordinate field  754 . 
         [0264]    Alternatively, if the process step corresponding to the detected position is the process step to be carried out later than a fifth process step  251 , the sensed information analysis module  134  stores a value obtained by adding the value of the sensed Y-coordinate to a value obtained by subtracting the value of the sensed X-coordinate from a value obtained by doubling the X-coordinate regarding any of the points on a line in which the fourth in-process item storage space  242  contacts with the fifth process-step work region  251 , in the output coordinate field  754 . 
         [0265]    Subsequently, the sensed information analysis module  134  determines the alert situation for each worker of the sensing target (Step S 206 ). 
         [0266]    Specifically, with regard to the output information table  750 , for each worker of the sensing target, the sensed information analysis module  134  stores the information called “present” in the alert field  756  by assuming that a useless movement is being performed or a necessary working action is not being performed if the width between the upper limit and the lower limit of the value of the output coordinate field  754  exceeds a predetermined threshold value or if an increase/decrease amount of the value of the combined acceleration field  755  within a predetermined period is equal to or smaller than a predetermined threshold value. 
         [0267]    It should be noted that the event to be alerted is not limited to the above description as long as the alert is issued if the worker is not performing a predefined work. 
         [0268]    Subsequently, the output information generation module  132  uses the information within the output information table  750  to form and display a screen (Step S 207 ). 
         [0269]    Specifically, with regard to the records of the output information table  750 , for each of the values of the ID field  751 , the output information generation module  132  displays a change over time of the combined acceleration in the position of the carried-out process step in the form of a graph. Further, the line segment is displayed in the position of the process step carried out by the worker, to thereby form and display an activity situation display screen  780  illustrated in  FIG. 17 . 
         [0270]      FIG. 17  is a diagram illustrating an example of the activity situation display screen  780 . 
         [0271]    The activity situation display screen  780  includes a process-step display field  781 , a worker axis line  782 , a process-step axis line  783 , a worker display field  784 , an acceleration indicating line  785 , and a movement area line  788  of the worker. 
         [0272]    The process-step display field  781  is the same as the process step display field  651  according to the second embodiment, and hence description thereof is omitted. However, the display breadths of the respective fields of the process-step display field  781  is set wider in proportion to the lengths of the process steps in terms of the layout in a direction toward the subsequent process step. 
         [0273]    The worker axis line  782 , which serves as a vertical axis directed upward from the bottom of the activity situation display screen  780 , indicates an axis along which the IDs or names that identify the workers are arrayed in order. 
         [0274]    The process-step axis line  783 , which serves as a horizontal axis directed rightward from the left of the activity situation display screen  780 , indicates the flow of the work process step. It should be noted that the position within each of the process steps of the process-step display field  781 , which corresponds to a predetermined position within each of the process steps in terms of the layout, is defined to have a proportional relationship between the length from the start point of the process step in terms of the layout up to the position in a direction toward the subsequent process step and the length up to the display position in terms of the display in a direction from the left edge of the field of each of the process steps of the process-step display field  781  toward the right edge thereof. 
         [0275]    The worker display field  784  indicates a name of the worker corresponding to the worker on the worker axis line  782 . 
         [0276]    The acceleration indicating line  785  indicates a graph in which an increase amount of the magnitude of a combined acceleration for each of the times at which the detection is performed by the sensor  161  attached to the worker is recorded along a time axis (whose origin point is set in a predetermined position at the top of the left edge of the process step) provided to each process step in a direction parallel to the process-step axis line  783 . 
         [0277]    The increase amount of the magnitude of the acceleration, which is one of the axes of the acceleration indicating line  785 , is provided in a direction parallel to the worker axis line  782 . 
         [0278]    It should be noted that if the worker performs a work in another process step, the acceleration indicating line  785  is fragmentarily displayed in a portion indicating the corresponding time instant of the process step performed while discontinuing the graph. Therefore, with regard to a worker A of  FIG. 17 , an acceleration indicating line  786  indicates the combined acceleration obtained when the work is performed in the third process-step work region, and an acceleration indicating line  787  is a fragment indicating the combined acceleration of the work performed thereafter in the second process-step work region. 
         [0279]    The movement area line  788  of the worker indicates an area within which the worker has moved. 
         [0280]    The area within which the worker has moved is represented by a line that couples points to one another, the points being displayed in the display positions within the respective process steps of the process-step display field  781 , which correspond to the positions of the worker within the respective process steps in terms of the layout. For example, the activity situation display screen  780  of  FIG. 17  indicates that the worker A has moved across the second process-step work region, the second in-process item storage space, and a part of the third process-step work region. 
         [0281]    It should be noted that the acceleration indicating line of a worker B of  FIG. 17  has vertically two stages, in which the upper stage indicates a regular-time work and the lower stage indicates an excessive work (so-called overtime work). 
         [0282]    In the above-mentioned manner, according to the activity situation display screen  780 , the movement area of the worker and the quantity of acceleration of the worker on a per-time basis can be presented at a glance. 
         [0283]    Then, the detected information management module  133  returns the processing to Step S 201 , and receives the sensed information. 
         [0284]    The flow of the situation display processing in the third embodiment has been described above. 
         [0285]    According to the third embodiment of the present invention, the sensed information processing apparatus  100  can detect the position and the acceleration of the worker being the sensing target, determine the area of the process step that has been carried out and the change amount of an action on a time-by-time basis, and display the area and the change amount in the form of an at-a-glance chart. 
         [0286]    Next,  FIGS. 18 to 22  are referenced to describe the fourth embodiment of the present invention. 
         [0287]    A sensed information processing apparatus  800  according to the fourth embodiment of the present invention is, in principle, the same as the sensed information processing apparatus  100  according to the first embodiment, and hence the following description is directed to different points therebetween. 
         [0288]      FIG. 18  is a schematic diagram illustrating the sensed information processing apparatus  800  according to the fourth embodiment of the present invention. 
         [0289]    A storage unit  820  includes a work identification regional information storage area  825  in addition to the storage areas according to the first embodiment. 
         [0290]    The work identification regional information storage area  825  stores a detailed region table  860 . 
         [0291]      FIG. 19(   a ) is a diagram illustrating in detail the arrangement concerning an A01 region of the first process-step work region  211  of the workplace  2  illustrated in  FIG. 6 . 
         [0292]    A Z01 detailed region  810  is a region surrounded by the point expressed by (0,0), a point expressed by (8500,7500), a point expressed by (0,7500), and a point expressed by (8500,0). 
         [0293]    A Z02 detailed region  820  is a region surrounded by the point expressed by (8500,0), a point expressed by (17500,7500), the point expressed by (8500,7500), and a point expressed by (17500,0). 
         [0294]    A Z03 detailed region  830  is a region surrounded by the point expressed by (17500,0), a point expressed by (25000,7500), the point expressed by (17500,7500), and a point expressed by (25000,0). 
         [0295]    A Z04 detailed region  840  is a region surrounded by the point expressed by (0,7500), a point expressed by (14000,15000), a point expressed by (0,15000), and a point expressed by (14000,7500). 
         [0296]    A Z05 detailed region  850  is a region surrounded by the point expressed by (14000,7500), a point expressed by (25000,15000), the point expressed by (14000,15000), and the point expressed by (25000,7500). 
         [0297]    Based on such a detailed arrangement as illustrated in  FIG. 19(   a ),  FIG. 19(   b ) illustrates the detailed region table  860  that stores information that defines an area of each of the detailed regions by coordinates of two vertices connected by a diagonal line of each of the detailed regions. 
         [0298]    The detailed region table  860  includes a place ID field  861 , a start X-coordinate field  862 , a start Y-coordinate field  863 , an end X-coordinate field  864 , an end Y-coordinate field  865 , and a work name field  866 . 
         [0299]    The place ID field  861  stores a place ID as information that identifies the detailed region. 
         [0300]    The start X-coordinate field  862  stores information regarding the X-coordinate of a first vertex being one vertex of two vertices that are opposed to each other across a diagonal line of the detailed region. 
         [0301]    The start Y-coordinate field  863  stores information regarding the Y-coordinate of the first vertex of the detailed region. 
         [0302]    The end X-coordinate field  864  stores information regarding the X-coordinate of a second vertex opposed to the first vertex across the diagonal line of the detailed region. 
         [0303]    The end Y-coordinate field  865  stores information regarding the Y-coordinate the second vertex. 
         [0304]    The indication X-coordinate field  866  stores information regarding the coordinate that determines the display position on the screen used to indicate the position or the like of the product or the worker on a detailed display screen  950  described later. 
         [0305]    The work name field  867  stores a name of the work carried out in the region determined by the value stored in the place ID field  861 . For example, if the value of the place ID field  861  is “Z01” and the value of the work name field  867  is “A assembly work”, it is understood that the “Z01” detailed region is the detailed region in which “A assembly work” is carried out. 
         [0306]    In the fourth embodiment, an output information table stored in the output information storage area  124  of the storage unit  820  is an output information table  900  illustrated in  FIG. 20 . 
         [0307]    The output information table  900  includes a time field  901 , an ID field  902 , an output coordinate field  903 , an X-coordinate field  904 , a Y-coordinate field  905 , a place ID field  906 , and a work name field  907 . 
         [0308]    The time field  901  stores information that determines a time instant at which the detection value detected by the sensor  161  is detected. In this embodiment, information that determines a time instant at which the detection value detected by the sensor  161  is received is stored. 
         [0309]    The ID field  902  stores information that determines an ID being identification information for identifying the worker or the work target product to which the sensor  161  is attached. 
         [0310]    The output coordinate field  903  stores information that determines an output coordinate used when the position of the worker or the work target product to which the sensor  161  is attached is displayed on a screen. 
         [0311]    The X-coordinate field  904  stores a value regarding the X-coordinate of the detection value detected by the sensor  161  determined by the ID field  902 . 
         [0312]    The Y-coordinate field  905  stores a value regarding the Y-coordinate of the detection value detected by the sensor  161  determined by the ID field  902 . 
         [0313]    The place ID  906  stores a place ID that indicates the detailed region determined from the coordinates stored in the X-coordinate field  904  and the Y-coordinate field  905 . 
         [0314]    The work name  907  stores a name of the work performed in the place ID stored in the place ID  906 . 
         [0315]    The control unit  830  includes an output information generation module  832 , a sensed information management module  833 , and a sensed information analysis module  834 , in addition to the same input information reception module  131  as in the first embodiment. 
         [0316]    The output information generation module  832  forms an output screen by combining information to be output and a screen layout, and makes the output unit  142  to display the output screen. 
         [0317]    The sensed information management module  833  performs a processing which stores the detection value received from each of the sensors  161  via the communication unit  143  described later in the sensed information table  200  and the output information table  900 . 
         [0318]    It should be noted that the sensed information management module  833  stores a correlation between the sensor ID of the sensor  161  and the ID for identifying the worker, and stores an ID corresponding to the sensor ID attached to a measured value received from the sensor  161  in the ID field  202  of the sensed information table  200 , and the ID field  902  of the output information table  900 . 
         [0319]    Further, the sensed information management module  833  stores the time instant at which the measured value is received in a region (not shown) of the storage unit  820 . 
         [0320]    In the same manner as the sensed information analysis module  134  of the first embodiment, the sensed information analysis module  834  uses the information stored in the sensed information table  200  to determine which process step, a target to which the sensor  161  is attached is in, for each of the sensors  161 . 
         [0321]    In addition, the sensed information analysis module  834  reads the value of the X-coordinate field  904  and the Y-coordinate field  905  of the output information table  900 , and, from among records stored in the detailed region table  860 , determines a record in which the read X-coordinate exists between the value of the start X-coordinate field  862  and the value of the end X-coordinate field  864  and in which the read Y-coordinate exists between the value of the start Y-coordinate field  863  and the value of the end Y-coordinate field  865 . 
         [0322]    Then, the sensed information analysis module  834  determines the place ID stored in the corresponding place ID field  861 , coordinate information stored in the indication X-coordinate field  866 , and a work name stored in the work name field  867  of the determined record. 
         [0323]    Then, the sensed information analysis module  834  stores the place ID, the coordinate information, and the work name in the place ID field  906 , the output coordinate field  903 , and the work name field  907  of the output information table  900 , respectively. 
         [0324]    In the same manner as in  FIG. 8 , a hardware configuration of the sensed information processing apparatus  800  according to the fourth embodiment is a computer such as a client PC, a workstation, a server device, each of various mobile phone terminals, or a PDA. 
         [0325]    The input information reception module  131 , the output information generation module  832 , the sensed information management module  833 , and the sensed information analysis module  834  of the sensed information processing apparatus  800  are implemented by programs that make the arithmetic operation device  113  of the sensed information processing apparatus  800  to perform processings. 
         [0326]    Those programs, which are stored within the main memory device  114  or the external storage device  115 , are loaded onto the main memory device  114  before the execution thereof, and executed by the arithmetic operation device  113 . 
         [0327]      FIG. 21  illustrates a processing flow of a situation display processing according to the fourth embodiment. 
         [0328]    First, the sensed information management module  833  receives the detection value transmitted from the sensor  161  via the communication unit  143  at predetermined intervals (for example, every one second) (Step S 301 ). 
         [0329]    Subsequently, the sensed information management module  833  stores the detection values received in Step S 301  in the sensed information table  200  and the output information table  900  (Step S 302 ). 
         [0330]    Specifically, the sensed information management module  833  stores the detection values received in Step S 301  in the X-coordinate field  203  and the Y-coordinate field  204  of the sensed information table  200  and the X-coordinate field  904  and the Y-coordinate field  905  of the output information table  900 . 
         [0331]    Subsequently, the sensed information analysis module  834  determines a work process step from sensed information (Step S 303 ). 
         [0332]    Specifically, the sensed information analysis module  834  reads the values of the X-coordinate field  904  and the Y-coordinate field  905  of the output information table  900 . 
         [0333]    Then, from among the records stored in the region table  450 , the sensed information analysis module  834  determines a record in which the read X-coordinate exists between the value of the start X-coordinate field  452  and the value of the end X-coordinate field  454  and in which the read Y-coordinate exists between the value of the start Y-coordinate field  453  and the value of the end Y-coordinate field  455 . 
         [0334]    Then, the sensed information analysis module  834  determines the process-step ID stored in the corresponding process-step ID field  456  of the determined record. 
         [0335]    Subsequently, the sensed information analysis module  834  determines the output coordinate from the process-step ID of the work process step determined in Step S 303  (Step S 304 ). 
         [0336]    Specifically, from among the records stored in the process-step definition table  300 , the sensed information analysis module  834  determines the values of the process-step name field  303  and the indication X-coordinate field  305  of the record in which the process-step ID determined in Step S 303  matches the value of the process-step ID field  301  within the process-step definition table  300 . 
         [0337]    Then, the sensed information analysis module  834  stores the information on the determined process-step name and the information on the indication X-coordinate in the process step field  503  and the output coordinate field  504 , respectively, of the output information table  500 . 
         [0338]    Subsequently, the sensed information analysis module  834  determines a work detailed place from the sensed information (Step S 305 ). 
         [0339]    Specifically, the sensed information analysis module  834  reads the values of the X-coordinate field  904  and the Y-coordinate field  905  of the output information table  900 . 
         [0340]    Then, from among records stored in the detailed region table  860 , the sensed information analysis module  834  determines a record in which the read X-coordinate exists between the value of the start X-coordinate field  862  and the value of the end X-coordinate field  864  and in which the read Y-coordinate exists between the value of the start Y-coordinate field  863  and the value of the end Y-coordinate field  865 . 
         [0341]    Then, the sensed information analysis module  834  determines the place ID stored in the corresponding place ID field  861 , the coordinate information stored in the indication X-coordinate field  866 , and the work name stored in the work name field  867  of the determined record. 
         [0342]    Then, the sensed information analysis module  834  stores the place ID, the coordinate information, and the work name in the place ID field  906 , the output coordinate field  903 , and the work name field  907  of the output information table  900 , respectively. 
         [0343]    Subsequently, the output information generation module  832  uses the information within the output information table  500  to form and display a screen (Step S 306 ). 
         [0344]    Specifically, with regard to the records of the output information table  500 , the output information generation module  832  displays points in display positions determined by the output coordinate field  504  in ascending order of the values of the time field  501  for each value of the ID field  502 , to thereby form and display the situation display screen  550  illustrated in  FIG. 10 . 
         [0345]    Subsequently, the sensed information analysis module  834  judges whether or not an instruction for detailed display has been received on the situation display screen  550  (Step S 307 ). 
         [0346]    Specifically, the sensed information analysis module  834  judges whether or not the instruction for detailed display has been received by inquiring of the input information reception module  131  on whether or not a detailed display instruction that specifies the specific process step within the process-step display field  551  of the situation display screen  550  has been received. 
         [0347]    If the instruction for detailed display has not been received (“No” in Step S 307 ), the sensed information management module  833  returns the processing to Step S 301 , and receives the sensed information. 
         [0348]    If the instruction for detailed display has been received (“Yes” in Step S 307 ), with regard to the records of the output information table  900 , the output information generation module  832  displays the points in the display positions determined by the output coordinate field  903  in ascending order of the values of the time field  901  for each value of the ID field  902  with regard to the process step for which the instruction has been received, to thereby form and display the detailed display screen  950  illustrated in  FIG. 22 . 
         [0349]    In this case, when a sensing target moves to a different work, the output information generation module  832  performs the displaying by adding an oblique line connecting the previous point in the work before the movement to the point after the movement. 
         [0350]      FIG. 22  is a diagram illustrating an example of the detailed display screen  950 . 
         [0351]    The detailed display screen  950  includes a process-step display field  951 , a time instant axis line  952 , a work axis line  953 , a present time instant indicating line  954 , a worker position indicating line  955 , and a product position indicating line  956 . 
         [0352]    The process-step display field  951  includes display fields in order of work with regard to the works of the process step of the specified display target. In  FIG. 22 , the process-step display field  951  includes display fields of “A assembly work”, “B assembly work”, “C part welding work”, “D part polishing work”, and “E part polishing work” from the left to the right of the screen. 
         [0353]    The respective display fields of the process-step display field  951  correspond to the Z01 detailed region  810 , the Z02 detailed region  820 , the Z03 detailed region  830 , the Z04 detailed region  840 , and the Z05 detailed region  850  with regard to the first process-step work region  211  of the workplace  2 . 
         [0354]    It should be noted that the value of the indication X-coordinate field  866  of the detailed region table  860  and the value of the output coordinate field  903  of the output information table  900  are values that determine the coordinates in a horizontal position around the center of the respective work fields of the process-step display field  951 . 
         [0355]    Further, the display breadths of the respective work fields of the process-step display field  951  may be set to be proportionate to the lengths of the detailed regions in terms of the layout, or may be simply set as regular intervals. 
         [0356]    The time instant axis line  952 , which serves as a vertical axis directed downward from the top of the detailed display screen  950 , indicates a flow of the time instant. 
         [0357]    The work axis line  953 , which serves as a horizontal axis directed rightward from the left of the detailed display screen  950 , indicates a flow of the work. 
         [0358]    The present time instant indicating line  954  indicates a time instant corresponding to the present time instant on the time instant axis line  952 . 
         [0359]    The worker position indicating line  955  is a line that connects points indicating the positions on a time-by-time basis of the sensor  161  attached to the worker. 
         [0360]    The product position indicating line  956  is a line that connects points indicating the positions on a time-by-time basis of the sensor  161  attached to the product of the work target or the like. 
         [0361]    In other words, for example, if the worker of the sensing target exists in the first process-step work region  211 , the situation display screen  950  displays the point in the position corresponding to the detected time instant in the left side portion or at the center of the process-step display f field  951 , and displays the points, which are recorded from the start of detection until the present time instant, as the worker position indicating line  955 . 
         [0362]    Further, if the product or the worker of the sensing target exists in the Z01 detailed region  810  of the first process-step work region  211 , the detailed display screen  950  displays the point in the position corresponding to the detected time instant within the corresponding work field in the right side portion of the process-step display field  951 , and displays the points, which are recorded from the start of detection until the present time instant, as the product position indicating line  956 . 
         [0363]    Then, the detected information management module  133  returns the processing to Step S 301 , and receives the sensed information. 
         [0364]    The flow of the situation display processing in the fourth embodiment has been described above. 
         [0365]    According to the fourth embodiment of the present invention, in the same manner as the sensed information processing apparatus  100  according to the first embodiment, the sensed information processing apparatus  800  can detect the positions of the worker and the product being the sensing targets, determine the process step and the time instant, and use the situation display screen  550  to present the process step and the passage of time in the form of an at-a-glance chart. Further, in addition thereto, the sensed information processing apparatus  800  can detect the further detailed positions of the worker and the product being the sensing targets, determine the work and the time instant within the process step, and use the detailed display screen  950  to present the work and the passage of time within the process step in the form of an at-a-glance chart. 
         [0366]    The specific descriptions have been made above based on the first to fourth embodiments, but the present invention is not limited thereto, and various changes can be made thereto without departing from the gist thereof. 
         [0367]    For example, when the sensed information is received from the sensor  161  in Step S 004  of the sensing processing according to the above-mentioned first embodiment, the received detection value may be used by eliminating a high-frequency component from the detection value instead of being used as it is. 
         [0368]    With this configuration, the sensed information exhibiting little noise can be recorded. 
         [0369]    Further, when the sensed information is received from the sensor  161  in Step S 201  of the sensing processing according to the above-mentioned first embodiment, the detection values of the X-axis, the Y-axis, and the Z-axis may be received as the magnitude of a vector obtained by combining the detection values of the X-axis, the Y-axis, and the Z-axis instead of being received as it is. 
         [0370]    With this configuration, it is possible to reduce a processing load that occurs when the calculation is performed by combining the accelerations in Step S 204 . 
         [0371]    Further, when the process step and the passage of time are displayed in Step S 005  of the situation display processing according to the above-mentioned first embodiment, a locus of the worker or the product of the sensing target may be additionally displayed over layout information on the workplace  2 . 
         [0372]    With this configuration, it is possible to figure out a concrete image of the situation of the workplace  2  while reviewing the process step and the passage of time. 
         [0373]    Further, the sensed information processing apparatus  100  or  800  is configured to operate on a standalone basis, but the present invention is not limited thereto, and may serve as, for example, a server device which provides a service via a communication protocol such as a hyper text transfer protocol (HTTP) to receive an input instruction from another terminal device via a network and make the terminal device to display an output. 
         [0374]    With such changes, the user becomes capable of operating the sensed information processing apparatus  100  or  800  through another terminal connected to the network, and it is possible to enhance the degree of freedom of the equipment configuration and the convenience of the user. 
         [0375]    Further, in the above-mentioned first embodiment to fourth embodiment, the sensed information processing apparatus  100  receives the information transmitted from the sensor  161  and determines the process step or a detailed work at which the sensor  161  is located, but the present invention is not limited thereto as long as the sensed information processing apparatus  100  can receive such information as to determine the process step or the detailed work. 
         [0376]    For example, a sensing device mounted for each process step or each detailed work may sense the radio wave transmitted by a radio wave transmitting device attached to the target worker and transmit the identification information on the worker and information that identifies the sensing device to the sensed information processing apparatus  100 , and the sensed information processing apparatus  100  may determine the process step and the detailed work by the information that identifies the sensing device. 
         [0377]    With this configuration, the sensor  161  can be easily downsized. 
         [0378]    Further, the works to be sensed are not limited to the works within a factory as illustrated by the workplace  2 , but can include various works and actions such as works in a kitchen of a restaurant or actions of a player in a sports game. 
         [0379]    It should be noted that the sensed information processing apparatus  100  or  800  is not only to be dealt as an apparatus, but can also be dealt in units of program components that implement operations of the apparatus. 
         [0380]    Next described is the fifth embodiment for determining a work content without forcing the worker into a special operation. 
         [0381]      FIG. 23  is a diagram illustrating a work information processing system  2000  according to the fifth embodiment of the present invention. 
         [0382]    The work information processing system  2000  according to this embodiment includes a worker sensor  1161 A and a worker sensor  1161 B (hereinafter, referred to as “worker sensor  1161 ” in a case where the individual worker sensors are not particularly distinguished from each other) that are attached to a worker, an apparatus sensor  1162  attached to a processing apparatus, a product sensor  1163  attached to a product, an environment sensor  1164  mounted in a workplace or the like which measures a temperature and a humidity, and a sensed information processing apparatus  1100 . 
         [0383]    The worker sensor  1161  is a sensor which detects an action and a position of a person to which the worker sensor  1161  is attached. In this embodiment, the worker sensor  1161  has a function of an acceleration sensor which measures the accelerations of three orthogonal directions (set as X-direction, Y-direction, and Z-direction) and a position sensor such as a global positioning system (GPS) which measures the position within the work region on a plane (two dimensions of the X-coordinate and the Y-coordinate). 
         [0384]    It should be noted that the worker sensor  1161  detects the acceleration including the gravitational acceleration in units of 1/1,000 G. However, the present invention is not limited thereto, and the worker sensor  1161  may, for example, detect the detection value by canceling a gravitational acceleration component. 
         [0385]    Naturally, the worker sensor  1161  is not limited to the acceleration sensor or the position sensor, and may be any sensor which can detect the action and the position of the person to which the sensor is attached, for example, may be an oximeter sensor which can detect an oxygen concentration in the blood of the person to which the sensor is attached, a temperature sensor, a current sensor, or the like. 
         [0386]    It should be noted that in  FIG. 23 , the worker sensor  1161 A is attached to the worker&#39;s left foot, and the worker sensor  1161 B is attached to his/her waist, but the present invention is not limited to such a mode, and any mode can be employed as long as actions at a plurality of sites of the worker can be detected by a plurality of worker sensors  1161 . 
         [0387]    Further, the worker sensor  1161  transmits the detection value to the sensed information processing apparatus  1100  via radio. 
         [0388]    The apparatus sensor  1162  is a sensor which detects an operational status of the processing apparatus being a tool for work to which the apparatus sensor  1162  is attached. In this embodiment, the apparatus sensor  1162  is a voltage sensor which measures a voltage applied to the processing apparatus, a gas flow sensor of a welding apparatus, or the like. 
         [0389]    It should be noted that the apparatus sensor  1162  is not limited to the voltage sensor or the gas flow sensor, and may be any sensor which can detect the operational status of an apparatus to which the sensor is attached, for example, may be the temperature sensor which can detect heat generated by the apparatus to which the sensor is attached or the like. 
         [0390]    Further, the apparatus sensor  1162  transmits the detection value to the sensed information processing apparatus  1100  via radio. 
         [0391]    The product sensor  1163  is a sensor which detects the work being performed on the work target product to which the product sensor  1163  is attached and the position. In this embodiment, the product sensor  1163  has a function of the acceleration sensor which measures the accelerations of the three orthogonal directions (set as X-direction, Y-direction, and Z-direction) regarding a target product and the position sensor such as a global positioning system (GPS) which measures the position within the work region on a predetermined plane (two dimensions of the X-coordinate and the Y-coordinate). 
         [0392]    It should be noted that the product sensor  1163  is not limited to the acceleration sensor or the position sensor, and may be any sensor which can detect the work being performed on the product to which the sensor is attached and the position of the product, for example, may be the temperature sensor which can detect heat generated by the apparatus to which the sensor is attached or the like. 
         [0393]    Further, the product sensor  1163  transmits the detection value to the sensed information processing apparatus  1100  via radio. 
         [0394]    The environment sensor  1164  is a sensor which detects environmental information on the workplace in which the environment sensor  1164  is attached. In this embodiment, the environment sensor  1164  is the temperature sensor which measures a temperature of the workplace, a humidity sensor which measures a humidity of the workplace, or the like. 
         [0395]    It should be noted that the environment sensor  1164  is not limited to the temperature sensor or the humidity sensor, and may be any sensor which can detect the situation of the environment in which the sensor is attached, for example, may be an illuminance sensor which can detect a brightness of the workplace in which the sensor is attached or the like. 
         [0396]    Further, the environment sensor  1164  transmits the detection value to the sensed information processing apparatus  1100  via radio. 
         [0397]    The sensed information processing apparatus  1100  uses an antenna  1150  to receive the respective detection values transmitted from the worker sensor  1161 , the apparatus sensor  1162 , the product sensor  1163 , and the environment sensor  1164 . 
         [0398]      FIG. 24  is a schematic diagram of the sensed information processing apparatus  1100 . 
         [0399]    As illustrated in the figure, the sensed information processing apparatus  1100  includes a storage unit  1120 , a control unit  1130 , an input unit  1141 , an output unit  1142 , and a communication unit  1143 . 
         [0400]    The storage unit  1120  includes a sensed information storage area  1121 , a worker information storage area  1122 , a work load information storage area  1123 , a sensor mounting information storage area  1124 , a scheduled work information storage area  1125 , an output information storage area  1126 , and a work determining information storage area  1127 . 
         [0401]    The sensed information storage area  1121  stores a worker sensed information table  1200 , an apparatus sensed information table  1250 , an apparatus sensed information table  1300 , and an environment sensed information table  1350 . 
         [0402]    The worker sensed information table  1200  stores information sensed from the worker sensor  1161 . The apparatus sensed information table  1250  stores information sensed from the apparatus sensor  1162 . The apparatus sensed information table  1300  stores information sensed from the product sensor  1163 . The environment sensed information table  1350  stores information sensed from the environment sensor  1164 . 
         [0403]      FIG. 25  illustrates a structure example of the worker sensed information table  1200 .

         [0513]    Stored in the work determining information storage area  1127  is a work definition file  1650  for storing information that determines the work content from among the information sensed from the sensors  1161  to  1163 . 
         [0514]      FIG. 34  illustrates a structure example of the work definition file  1650 . 
         [0515]    The work definition file  1650  is a file that associates the work content with the detection value that is received from the sensor and is to be a condition for determining the work content. 
         [0516]    Specifically, the work definition file  1650  stores one or a plurality of description sentences  1651  to  1653  that are defined per work content. It should be noted that the description sentence  1651  is a sentence having a syntax that describes a condition following “if” and describes the work content to be determined following “then”. 
         [0517]    For example, the description sentence  1651  “if (a=c) and (g=“ON”) then “processing”” indicates a definition that “the work content is “processing” if the value of the variable “a” and the value of the variable “c” are the same and if the value of the variable “g” is equal to “ON”. Here, the variables “a” and “c” included in the description sentence  1651  are variables that determine the fields, which store the respective detection values, of the worker sensed information table  1200 , the apparatus sensed information table  1250 , the product sensed information table  1300 , and the environment sensed information table  1350  that are stored in the sensed information storage area  1121 . 
         [0518]    It should be noted that in this embodiment, it is desired that variables obtained from a plurality of tables are used in the condition of one description sentence. In particular, it is desired that variables obtained from the worker sensed information table  1200  and other tables are used. 
         [0519]      FIG. 24  is referenced again for the description. 
         [0520]    The control unit  1130  includes an input information reception module  1131 , an output information generation module  1132 , a sensed information management module  1133 , and a sensed information processing module  1134 . 
         [0521]    The input information reception module  1131  receives information input through the input unit  1141  described later. 
         [0522]    The output information generation module  1132  forms an output screen by combining information to be output and a screen layout, and makes the output unit  1142  described later to display the output screen. 
         [0523]    The sensed information management module  1133  performs a processing which stores the detection value received from each of the sensors  1161  to  1164  via the communication unit  1143  described later in the sensed information storage area  1121 . 
         [0524]    Specifically, the sensed information management module  1133  stores a correlation between the sensor ID of the worker sensor  1161  and the worker ID for identifying the worker, and stores a worker ID corresponding to the sensor ID attached to a measured value received from the worker sensor  1161  in the ID field  1202  of the worker sensed information table  1200 . 
         [0525]    Further, the sensed information management module  1133  searches the values of the mounted sensor field  1503  of the sensor mounting table  1500  based on each of the sensor IDs of the sensors  1162  to  1164  to determine the value of the mounting target field  1501 , and stores the received measured value in the corresponding table among the apparatus sensed information table  1250 , the product sensed information table  1300 , and the environment sensed information table  1350  for each of the determined mounting targets. 
         [0526]    From the information stored in the sensed information storage area  1121 , the sensed information processing module  1134  determines the work of the worker and calculates a work load or the like. 
         [0527]    Specifically, the sensed information processing module  1134  determines the work content from the detection value that is detected by each of the sensors  1161  to  1163  and stored in the sensed information storage area  1121 . In that case, the sensed information analysis module  1134  uses the work definition file  1650  within the work determining information storage area  1127  to determine the work content. 
         [0528]    Then, the sensed information processing module  1134  calculates the work load by using the determined work content, the information on the worker stored in the worker information table  1400  within the worker information storage area  1122 , and the information determining the work load which is stored in the work load information table  1450  stored in the work load information storage area  1123 . 
         [0529]    Further, the sensed information processing module  1134  calculates a value of an actually-performed work proportion from the determined work content. 
         [0530]    Then, the sensed information processing module  1134  stores each of the determined work content, the work proportion, and the work load in the output information table  1700  within the output information storage area  1126 . 
         [0531]    The input unit  1141  receives an input of information from an operator. 
         [0532]    The output unit  1142  outputs information. 
         [0533]    The communication unit  1143  performs transmission/reception of information through the antenna  1150 . 
         [0534]      FIG. 36  is a diagram illustrating a hardware configuration of the sensed information processing apparatus  1100  according to this embodiment. 
         [0535]    In this embodiment, the sensed information processing apparatus  1100  is a computer such as a client PC (personal computer), a workstation, a server device, each of various mobile phone terminals, or a personal digital assistant (PDA). 
         [0536]    The sensed information processing apparatus  1100  includes an input device  1111 , an output device  1112 , an arithmetic operation device  1113 , a main memory device  1114 , an external storage device  1115 , a communication device  1116 , and a bus  1117  that connects the respective devices. 
         [0537]    The input device  1111  is a device which receives an input such as a keyboard, a mouse, a touch pen, or other such pointing devices. 
         [0538]    The output device  1112  is a device which performs displaying such as a display. 
         [0539]    The arithmetic operation device  1113  is an arithmetic operation device such as a central processing unit (CPU). 
         [0540]    The main memory device  1114  is a memory device such as a random access memory (RAM). 
         [0541]    The external storage device  1115  is a nonvolatile storage device such as a hard disk drive or a flash memory. 
         [0542]    The communication device  1116  is a communication device which performs radio communications through an antenna, such as a radio communication unit. 
         [0543]    The input information reception module  1131 , the output information generation module  1132 , the sensed information management module  1133 , and the sensed information processing module  1134  of the sensed information processing apparatus  1100  are implemented by programs that make the arithmetic operation device  1113  of the sensed information processing apparatus  1100  to perform processings. 
         [0544]    The above-mentioned programs, which are stored within the main memory device  1114  or the external storage device  1115 , are loaded onto the main memory device  1114  before execution thereof, and executed by the arithmetic operation device  1113 . 
         [0545]    Further, the storage unit  1120  of the sensed information processing apparatus  1100  is implemented by the main memory device  1114  or the external storage device  1115  of the sensed information processing apparatus  1100 . 
         [0546]    The input unit  1141  of the sensed information processing apparatus  1100  is implemented by the input device  1111  of the sensed information processing apparatus  1100 . 
         [0547]    The output unit  1142  of the sensed information processing apparatus  1100  is implemented by the output device  1112  of the sensed information processing apparatus  1100 . 
         [0548]    The communication unit  1143  of the sensed information processing apparatus  1100  is implemented by the communication device  1116  of the sensed information processing apparatus  1100 . 
         [0549]    Next,  FIG. 37  is referenced to describe a preliminary setting processing according to this embodiment. 
         [0550]      FIG. 37  is a diagram illustrating a processing flow of the preliminary setting processing. 
         [0551]    First, the input information reception module  1131  receives an input of worker information (Step S 501 ). 
         [0552]    For example, the input information reception module  1131  receives information on the worker including the full name, the professional career, the height, the sex, the age, the task-based team to which the worker belongs, and the sensor ID of the attached worker sensor  1161 . 
         [0553]    Then, the sensed information management module  1133  stores the worker information of which the input is received in Step S 501  in the worker information table  1400  within the worker information storage area  1122  (Step S 502 ). 
         [0554]    Subsequently, the input information reception module  1131  receives an input of work load information (Step S 503 ). 
         [0555]    For example, the input information reception module  1131  receives the content of the work, the posture during the work, the sex, the age, conditions including the temperature of the work environment, and information on a work load point in a case where the conditions are satisfied. 
         [0556]    Then, the sensed information management module  1133  stores information on the work load point of which the input is received in Step S 503  in the work load information table  1450  within the work load information storage area  1123  (Step S 504 ). 
         [0557]    Subsequently, the input information reception module  1131  receives an input of sensor mounting information (Step S 505 ). 
         [0558]    For example, the input information reception module  1131  receives the mounting target of the sensor, the information that determines the region including the position of the mounting target, each of the IDs of the sensors  1162  to  1164  that are mounted, and information on the person in charge. 
         [0559]    Then, the sensed information management module  1133  stores the sensor mounting information of which the input is received in Step S 505  in the sensor mounting table  1500  within the sensor mounting information storage area  1124  (Step S 506 ). 
         [0560]    Subsequently, the input information reception module  1131  receives an input of scheduled work information (Step S 507 ). 
         [0561]    For example, the input information reception module  1131  receives the information that determines the time instant, the worker&#39;s name, and the scheduled work content. 
         [0562]    Then, the sensed information management module  1133  stores the scheduled work information of which the input is received in Step S 507  in the scheduled work information table  1550  within the scheduled work information storage area  1125  (Step S 508 ). 
         [0563]    The processing flow of the preliminary setting processing has been described above. 
         [0564]    By performing such a preliminary setting processing, for example, before the start of the work, the information indicating the work situation can be processed appropriately. 
         [0565]    It should be noted that the reception of the input information in Steps S 501 , S 503 , S 505 , and S 507  may be omitted if no changes are made to the contents that have already been set. 
         [0566]    Next,  FIG. 38  is referenced to describe the flow of the situation display processing according to this embodiment. 
         [0567]      FIG. 38  is a flowchart illustrating the flow of the situation display processing. 
         [0568]    First, the sensed information management module  1133  receives the detection value transmitted from each of the sensors  1161  to  1164  via the communication unit  1143  at predetermined intervals (for example, every two seconds) (Step S 601 ). 
         [0569]    Specifically, the sensed information management module  1133  receives the detection value transmitted from each of the sensors  1161  to  1164  via the communication unit  1143 . 
         [0570]    Subsequently, the sensed information management module  1133  stores the detection value received in Step S 601  in each of the tables within the sensed information storage area  1121  (Step S 602 ). 
         [0571]    Specifically, the sensed information management module  1133  stores the acceleration and the position received from the worker sensor  1161  in the worker sensed information table  1200 , stores the sensed information received from the apparatus sensor  1162  in the apparatus sensed information table  1250 , stores the sensed information received from the product sensor  1163  in the product sensed information table  1300 , and stores the temperature and the humidity received from the environment sensor  1164  in the environment sensed information table  1350 . 
         [0572]    Subsequently, the sensed information processing module  1134  primarily processes information stored in the sensed information storage area  1121  in Step S 602  (Step S 603 ). 
         [0573]    Specifically, the sensed information processing module  1134  consolidates the information in the basic information table  1600  by using, as the keys, the information in the time field  1201  of each record of the worker sensed information table  1200 , the time field  1251  of each record of the apparatus sensed information table  1250 , the time field  1301  of each record of the product sensed information table  1300 , and the time field  1351  of each record of the environment sensed information table  1350 . 
         [0574]    In a processing which performs consolidation, the sensed information processing module  1134  stores the value of the position field  1203  of the worker sensed information table  1200  in the worker position field  1602 . Further, the sensed information processing module  1134  determines the value of the worker acceleration (waist) field  1603  from a relationship among the values of the X-axis acceleration field  1204 , the Y-axis acceleration field  1205 , and the Z-axis acceleration field  1206  of the worker sensed information table  1200 . 
         [0575]    For example, if the value of an X-axis acceleration and the value of a Z-axis acceleration fall within a specific range including zero (for example, minus 50 mG to 50 mG) and if the value of a Y-axis acceleration falls within a specific range including the gravitational acceleration (1,000 mG) (for example, 900 mG to 1,100 mG), the sensed information processing module  1134  determines that a change amount of the detection value from the previous time instant indicates any one of the states “static”, “minute movement”, and “vertical movement” according to a predefined range including the change amount, and stores the result in the worker acceleration (waist) field  1603 . In this embodiment, the sensed information processing module  1134  judges that the change amount of the value of the Y-axis acceleration indicates a “static” state if being equal to or larger than 0 mG and equal to or smaller than 4 mG, a “minute movement” state if being larger than 4 mG and equal to or smaller than 30 mG, and a “vertical movement” state if being larger than 30 mG. 
         [0576]    Further, in the processing which performs consolidation, the sensed information processing module  1134  determines the posture of the worker by using the values of the X-axis acceleration field  1204 , the Y-axis acceleration field  1205 , and the Z-axis acceleration field  1206  of the worker sensed information table  1200 . It should be noted that in the processing which determines the posture of the worker, the sensed information processing module  1134  determines a predetermined range to which the value of the X-axis acceleration field  1204  of the worker sensed information table  1200  belongs, a predetermined range to which the value of the Y-axis acceleration field  1205  thereof belongs, and a predetermined range to which the value of the Z-axis acceleration field  1206  thereof belongs, determines an angle of the waist of the worker according to a combination of the determined ranges to which the values of the respective axes belong, and determines the value of the posture field  1604  based on the determined angle of the waist of the worker. 
         [0577]    For example, if the value of the X-axis acceleration and the value of the Z-axis acceleration fall within the specific range including zero (for example, minus 50 mG to 50 mG) and if the value of the Y-axis acceleration falls within the specific range including the gravitational acceleration (for example, 900 mG to 1,100 mG), the sensed information processing module  1134  determines that an “upright” state is indicated, and stores a value to that effect in the posture field  1604 . Further, if the resultant force of the X-axis acceleration, the Y-axis acceleration, and the Z-axis acceleration matches the gravitational acceleration, if the value of the X-axis acceleration falls within the specific range including zero (for example, minus 50 mG to 50 mG), and if the value of the Y-axis acceleration and the value of the Z-axis acceleration respectively fall within a predetermined range including a value obtained by dividing 1,000 by the square root of 2 (for example, range between plus and minus 50 mG of the value obtained by dividing 1,000 by the square root of 2), the sensed information processing module  1134  determines that a “forward-bending (state in which the worker tilts his/her upper body forward by 45°)” state is indicated, and stores a value to that effect in the posture field  1604 . 
         [0578]    Further, if the resultant force of the X-axis acceleration, the Y-axis acceleration, and the Z-axis acceleration matches the gravitational acceleration, if the value of the X-axis acceleration falls within the predetermined range including zero (for example, minus 50 mG to 50 mG), if the value of the Y-axis acceleration falls within a predetermined range including a value obtained by multiplying 500 mG by the square root of 3 (for example, range between plus and minus 50 mG of the value obtained by multiplying 500 mG by the square root of 3), and if the value of the Z-axis acceleration falls within a predetermined range including 500 mG (for example, range from 450 mG to 550 mG), the sensed information processing module  1134  determines that a “forward-leaning (state of being tilted forward at an angle smaller than the forward-bending)” state is indicated, and stores a value to that effect in the posture field  1604 . 
         [0579]      FIG. 39  are referenced to supplementarily describe a mechanism for determining the posture. 
         [0580]      FIG. 39  are diagrams illustrating the values of the acceleration acquired by the worker sensor  1161  attached to the waist among the worker sensors  1161  attached to the worker. 
         [0581]    First,  FIG. 39(   a ) is a diagram illustrating a relationship among an X-axis  1801 , a Y-axis  1802 , and a Z-axis  1803  of the worker sensor  1161  attached to a worker  1800 . 
         [0582]    With regard to the X-axis  1801 , the Y-axis  1802 , and the Z-axis  1803 , in a case where the worker  1800  is static in an upright posture, the X-axis  1801  is a horizontal direction extending from the center of his/her body (waist) toward a side of the body, the Y-axis  1802  is a vertical direction extending from the center of the body (waist) toward his/her feet, and the Z-axis  1803  is a horizontal direction extending from the center of the body (waist) toward the front side of the body. The X-axis  1801 , the Y-axis  1802 , and the Z-axis  1803  are perpendicular to one another. 
         [0583]    Further, as illustrated in  FIG. 39(   b ), in an upright state  1810  of the worker, the acceleration toward the Y-axis  1802  direction is detected as 1,000 mG (milli-G) being the gravitational acceleration by the worker sensor  1161 . 
         [0584]    In other words, if the acceleration of the X-axis  1801  and the acceleration of the Z-axis  1803  fall within the predetermined value range including zero (for example, range from minus 50 mG to 50 mG) and if the acceleration of the Y-axis  1802  falls within the predetermined value range including the gravitational acceleration (for example, range from 900 mG to 1,100 mG), it is highly probable that the worker  1800  is upright. 
         [0585]    Further, as illustrated in  FIG. 39(   c ), in a state  1820  in which the worker  1800  leans his/her upper body forward at an angle of 45°, the accelerations having substantially the same amount (both having the value obtained by dividing 1,000 mG by the square root of 2) are detected in the Z-axis  1803  and the Y-axis  1802 . In other words, if the acceleration of the Z-axis  1803  and the acceleration of the Y-axis  1802  have substantially the same amount, it is highly probable that the worker  1800  is in the forward-leaning state. 
         [0586]    Naturally, in the above-mentioned manner, the angle at which the worker is leaning forward may be determined from the ranges to which the value of the X-axis acceleration, the value of the Y-axis acceleration, and the value of the Z-axis acceleration belong, and a predefined posture corresponding to the angle of the forward-leaning may be determined, but the present invention is not limited thereto. The angle at which the worker is leaning forward may be determined from a proportional relationship among the value of the X-axis acceleration, the value of the Y-axis acceleration, and the value of the Z-axis acceleration, to thereby determine the posture of the worker. 
         [0587]    It should be noted that the values of the acceleration collected by the worker sensor  1161  are assumed to include a component that determines the posture and a kinetic component as a noise component, and hence the sensed information processing module  1134  can improve accuracy for determining the posture by setting the worker sensor  1161  to equalize the values of the acceleration recorded a predetermined number of times (for example, 40 times) for a predetermined period (for example, for 2 seconds) and transmitting the equalized value to the sensed information processing apparatus  1100 . This is because the equalization reduces the noise component. 
         [0588]      FIG. 38  is referenced again to describe the processing flow. 
         [0589]    In a consolidation processing of Step S 603 , if the value of the processing apparatus A&#39;s voltage field  1252  of the apparatus sensed information table  1250  exceeds a predetermined value (for example, 50 volts), the sensed information processing module  1134  stores information that the processing apparatus A is in operation in the operation field  1607  for the processing apparatus A. Further, the information on the position indicated by the value of the placement position field  1502  of the sensor mounting table  1500  is stored in the position field  1606  for the processing apparatus A. 
         [0590]    Similarly, in the consolidation processing of Step S 603 , if the value of the processing apparatus B&#39;s voltage field  1253  of the apparatus sensed information table  1250  exceeds the predetermined value, the sensed information processing module  1134  stores information that the processing apparatus B is in operation in the operation field  1610  for the processing apparatus B. Further, the information on the position indicated by the value of the placement position field  1502  of the sensor mounting table  1500  is stored in the position field  1609  for the processing apparatus B. 
         [0591]    Further, in the consolidation processing of Step S 603 , if the value of the welding apparatus A&#39;s gas flow rate field  1254  of the apparatus sensed information table  1250  exceeds a predetermined value (for example, 2 milliliters), the sensed information processing module  1134  stores information that the welding apparatus A is in operation in the operation field  1613  for the welding apparatus A. Further, the information on the position indicated by the value of the placement position field  1502  of the sensor mounting table  1500  is stored in the position field  1612  for the welding apparatus A. 
         [0592]    Similarly, in the consolidation processing of Step S 603 , if the value of the welding apparatus B&#39;s gas flow rate field  1255  of the apparatus sensed information table  1250  exceeds the predetermined value, the sensed information processing module  1134  stores information that the welding apparatus B is in operation in the operation field  1616  for the welding apparatus B. Further, the information on the position indicated by the value of the placement position field  1502  of the sensor mounting table  1500  is stored in the position field  1615  for the welding apparatus B. 
         [0593]    Then, in the consolidation processing of Step S 603 , the sensed information processing module  1134  stores the information that determines the region including the position indicated by the value of the position field  1303  of the product sensed information table  1300 , in the position field  1618  for the module A. Then, if there exists a change in the detection value from the adjacent previous time instant with regard to any one of the value of the X-axis acceleration field  1304 , the value of the Y-axis acceleration field  1305 , and the value of the Z-axis acceleration field  1306 , the sensed information processing module  1134  stores information that there is a movement in the module (product), in the dynamic/static state field  1619  for the module A according to the amount of the change. For example, if an absolute value of the change amount of the X-axis acceleration is equal to or larger than 0 mG and equal to or smaller than 8 mG, the sensed information processing module  1134  assumes the movement of the module A to be “static”, in other words, in the static state and stores a value to that effect in the dynamic/static state field  1619  for the module A. If the absolute value of the change amount exceeds 8 mG, the sensed information processing module  1134  assumes the movement to be “dynamic”, in other words, not in the static state and stores a value to that effect in the dynamic/static state field  1619  for the module A. 
         [0594]    In such a manner, the sensed information processing module  1134  primarily processes the sensed information. 
         [0595]    Subsequently, the sensed information processing module  1134  determines the work content of the worker from the primarily-processed information at each of the sensed time instants (Step S 604 ). 
         [0596]    Specifically, the sensed information processing module  1134  judges the record stored in the basic information table  1600  according to the conditions included in the work definition file  1650 , determines the work content of the record satisfying the conditions, and stores the information that determines the work content in the actually-performed work content field  1704  of the output information table  1700 . 
         [0597]    For example, if the value of the worker position field  1602  is “A”, if the value of the worker acceleration (waist) field  1603  is “minute”, and if the value of the operation field  1607  for the processing apparatus A is “ON”, in a case where the work content defined by the work definition file  1650  is “processing” under the same conditions, the sensed information processing module  1134  stores the fact of being in “processing” in the actually-performed work content field  1704  of the output information table  1700 . 
         [0598]    Further, for example, if the value of the worker acceleration (waist) field  1603  has changed from the position at the previous time instant, the sensed information processing module  1134  judges that the worker has moved on foot within the workplace, and stores the fact of being in the “movement on foot” in the actually-performed work content field  1704  of the output information table  1700 . 
         [0599]    Subsequently, the sensed information processing module  1134  determines the posture of the worker from the primarily-processed information at each of the sensed time instants (Step S 605 ). 
         [0600]    Specifically, the sensed information processing module  1134  acquires the information of the posture field  1604  from the record stored in the basic information table  1600 , and stores the information in the working posture field  1705  of the output information table  1700 . 
         [0601]    Subsequently, the sensed information processing module  1134  determines the work load on the worker from the work content determined in Step S 604 , the posture of the worker determined in Step S 605 , and the like (Step S 606 ). 
         [0602]    Specifically, the sensed information processing module  1134  searches the work load information table  1450  to determine the record satisfying the conditions from the value of the actually-performed work content field  1704  which indicates the work content determined in Step S 604 , the value of the working posture field  1705  which indicates the posture of the worker determined in Step S 605 , the value of the sex field  1405  which indicates the sex of the worker, the value of the age field  1406  which indicates the age of the worker, the value of the region field  1352  which indicates the region to which the position in which the worker exists belongs, and the value of the temperature field  1353  which indicates the temperature of the region. 
         [0603]    In the search processing, the sensed information processing module  1134  narrows the records of the work load information table  1450  down to the records in which the values of the work content field  1452  and the working posture field  1453  match the values of the actually-performed work content field  1704  and the working posture field  1705 , respectively, of the output information table  1700  and in which the value of the sex field  1454  matches the value of the worker&#39;s sex field  1405  of the worker information table  1400 . 
         [0604]    Then, the sensed information processing module  1134  further narrows the narrowed-down records down to the records in which the value of the tens place of the value of the age field  1454  matches the value of the tens place of the value of the age field  1406  of the worker information table  1400 . 
         [0605]    Then, from among the narrowed-down records, the sensed information processing module  1134  determines the record in which the value of the tens place of the value of the temperature field  1456  matches the value of the tens place of the value of the temperature field  1353  of the environment sensed information table  1350  regarding the position of the position field  1203  of the worker. 
         [0606]    Then, the sensed information processing module  1134  acquires the value of the load point field  1457  of the determined record, and stores the value in the work load point field  1706  of the output information table  1700 . 
         [0607]    Subsequently, the sensed information processing module  1134  stores a new cumulative work load point in the cumulative work load point field  1707  by adding the work load point determined in Step S 606  to the work load point obtained by accumulating the work load points at the respective previous time instants (Step S 607 ). 
         [0608]    Subsequently, the sensed information processing module  1134  determines the work proportion from the work content determined in Step S 604  (Step S 608 ). 
         [0609]    Specifically, the sensed information processing module  1134  stores the value corresponding to the content of the work in the actually-performed work proportion field  1709  with regard to the value of the actually-performed work content field  1704  of the output information table  1700  in which the work content determined in Step S 604  is stored. For example, the sensed information processing module  1134  stores a value of “1” for “processing” and a value of “2” for “welding” in the actually-performed work content field  1709 . 
         [0610]    Further, the sensed information processing module  1134  simultaneously stores the values of the worker name field  1552  and the scheduled work content field  1553  of the scheduled work information table  1550  in the corresponding worker name field  1702  and the corresponding scheduled work content field  1703 , respectively, of the output information table  1700 . 
         [0611]    Then, the sensed information processing module  1134  stores the value corresponding to the content of the work in the scheduled work proportion field  1708  also with regard to the value of the scheduled work content field  1703 . 
         [0612]    Then, the sensed information processing module  1134  calculates a proportion of time in a period covering all the time instants indicated by the time field  1701  for each value stored in the scheduled work proportion field  1708 , in other words, each scheduled work content, and stores the proportion as a (scheduled) work proportion in a region (not shown) of the output information storage area  1126 . 
         [0613]    In the same manner, the sensed information processing module  1134  calculates a proportion of time in the period covering all the time instants indicated by the time field  1701  for each value stored in the actually-performed work proportion field  1709 , in other words, each actually-performed work content, and stores the proportion as an (actually-performed) work proportion in a region (not shown) of the output information storage area  1126 . 
         [0614]    Subsequently, the output information generation module  1132  forms and outputs an output screen  1900  (Step S 609 ). 
         [0615]      FIG. 40  is a diagram illustrating a structure example of the output screen  1900  output in Step S 609 . The output screen  1900  includes a work history display area  1910  and a work load display area  1920 . 
         [0616]    The work history display area  1910  includes a worker indicating icon  1911 , a time axis  1912  serving as a horizontal axis, a load axis  1913  serving as a vertical axis, a work indicating line  1914 , a work content display area  1915 , and a work load display area  1916 . The work indicating line  1914  is a line indicating the work content of the worker indicated by the worker indicating icon  1911  as a work line along the time axis  1912 . Further, the work load display area  1916  arranges and displays rectangular graphics, each of which is shown to be taller as the work load point is heavier, along the time axis  1912 . In other words, the taller the height of the rectangular graphic is, the heavier the work load on the worker is. 
         [0617]    The work load display area  1920  includes a worker indicating icon  1921 , a scheduled work proportion display field  1922  which indicates the scheduled work proportion, an actually-performed work proportion display field  1923  which indicates the actually-performed work proportion, an cumulative work load point display field  1924  which indicates the cumulative work load point, a scheduled work proportion graph display field  1925  which displays the scheduled work proportion in a pie chart, and an actually-performed work proportion graph display field  1926  which displays the actually-performed work proportion in a pie chart. 
         [0618]    The output information generation module  1132  makes the value of the worker name field  1702  of the output information table  1700  to be displayed with the worker indicating icons  1911  and  1921 . Then, the output information generation module  1132  makes the work indicating line  1914  and the work content display area  1915  to be displayed based on the values of the actually-performed work content field  1704 , and makes the graphics to be displayed in the work load display area  1916  based on the values of the work load point field  1706 . 
         [0619]    Further, in the scheduled work proportion graph display field  1925 , the output information generation module  1132  forms and displays a pie chart based on the information stored as the (scheduled) work proportion in the region (not shown) of the output information storage area  1126  in Step S 608 . In the same manner, in the actually-performed work proportion graph display field  1926 , the output information generation module  1132  forms and displays a pie chart based on the information stored as the (actually-performed) work proportion in the region (not shown) of the output information storage area  1126  in Step S 608 . Further, the output information generation module  1132  makes the value of the cumulative work load point field  1707  to be displayed in the cumulative work load point display field  1924 . Then, the sensed information processing module  1134  returns the control to Step S 601  to restart the processing. 
         [0620]    The processing flow of the situation display processing has been described above. 
         [0621]    By performing the situation display processing, it is possible to output and display detailed information on the work load that is hard to quantify on the display or the like in real time, and to allow a work supervisor or the like to quantitatively understand the load on the worker at a glance. 
         [0622]    The specific description is made above based on the fifth embodiment, but the present invention is not limited thereto, and various changes can be made without departing from the gist thereof. 
         [0623]    For example, the number of workers to be displayed in Step S 609  of the above-mentioned situation display processing is not limited to one, and a plurality of workers may be displayed. 
         [0624]    Specifically, as illustrated in  FIG. 41 , the output information generation module  1132  may display information on a plurality of workers  1950 ,  1951 ,  1960 , and  1961  in the work history display area and the work load display area. 
         [0625]    With this configuration, the information can be compared among a plurality of workers. In other words, this configuration is useful for improvement of work efficiency by, for example, leveling the work loads or determining the worker exhibiting high work efficiency to extract a point of his/her superiority in comparison with the worker exhibiting low working efficiency. 
         [0626]    Further, as illustrated in a work content display area  1953  of  FIG. 41 , the output information generation module  1132  may display a characteristic work content. In other words, the work content whose work time lasted for a predetermined period or longer may be displayed in the work content display area  1953 . 
         [0627]    With this configuration, characteristic information can be displayed accurately when the work contents of the plurality of workers are indicated. 
         [0628]    Further, as illustrated in a work load display area  1952  of  FIG. 41 , the output information generation module  1132  may display the work loads by using a graph such as a line graph. 
         [0629]    With this configuration, the characteristic information can be displayed accurately even when the work contents of the plurality of workers are indicated. 
         [0630]    Further, when determining the work load in Step S 606 , the sensed information processing module  1134  may correct the work load point according to the work content of the worker performed so far. 
         [0631]    For example, even the work load on the same work may differ between the morning in which the work is started and the evening immediately before the work is finished, and hence the load point may be corrected by the time instant according to the work content (for example, the work load on the work at a time instant later than a predetermined time instant may be set 1.5 times heavier). Further, for example, in the same manner, the work load may differ between the states in which a cumulative work load is high and low when the same work is performed, and hence the load point may be corrected according to the cumulative work load (for example, the work load may be set 1.5 times heavier when the cumulative work load is higher than a predetermined value). Naturally, a combination thereof may be used to correct the load point. 
         [0632]    Further, the sensed information processing apparatus  1100  is configured to operate on a standalone basis, but the present invention is not limited thereto, and may serve as, for example, the server device which provides a service via a communication protocol such as a hyper text transfer protocol (HTTP) to receive an input instruction from another terminal device via a network and makes the terminal device to display an output. 
         [0633]    With such changes, the user becomes capable of operating the sensed information processing apparatus  1100  through another terminal connected to the network, and it is possible to enhance the degree of freedom of the equipment configuration and the convenience of the user. 
         [0634]    Further, in the above-mentioned embodiment, the sensed information processing apparatus  1100  receives the information on the position and the acceleration transmitted from the worker sensor  1161 , but the present invention is not limited thereto as long as the sensed information processing apparatus  1100  can receive such information as to determine the position, the work content, or the posture. 
         [0635]    For example, the sensing device mounted in each workplace may sense the radio wave transmitted by the radio wave transmitting device attached to the target worker, and transmit the identification information on the worker and the information that identifies the sensing device to the sensed information processing apparatus  1100  so that the sensed information processing apparatus  1100  may determine the position and the posture of the worker captured by the sensing device by the information that identifies the sensing device. 
         [0636]    With this configuration, the worker sensor  1161  can be easily downsized. 
         [0637]    Further, the works to be sensed are not limited to the works within the factory, but can include various works and actions such as works in a kitchen of a restaurant or actions of a player in a sports game. 
         [0638]    It should be noted that the sensed information processing apparatus  1100  is not only to be dealt as an apparatus, but can also be dealt in units of program components that implement operations of the apparatus.
