Description:
BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    This invention relates to an information output device and computer-readable medium. 
         [0003]    2. Related Art 
         [0004]    In the related art, a technique is known whereby images are output by a projection apparatus (e.g. projector) according to data from an information terminal for the purpose of advertisement or publicity. 
         [0005]    For example, JP 2011-150221 A discloses a technique whereby a video output device connected to a video supply device is mounted on an apparatus for mounting the video output device and projects output light onto a screen. A reflection member provided to the apparatus for mounting the video output device reflects the output light projecting content from the video output device, thereby projecting the output light reflected by the reflection member onto the screen formed in the shape of an outline of the content. 
         [0006]    The technique of JP 2011-150221 A allows for projecting the content onto the screen formed in the shape of the outline of the content. This can enhance the picture of the output video or image, resulting in a customer-attracting effect or the like. 
         [0007]    However, the related art including that of JP 2011-150221 A unilaterally outputs information from an information terminal. This does not always meet the needs of viewers.

     DETAILED DESCRIPTION 
       [0016]    An embodiment of the invention (hereinafter referred to as the embodiment) will be described below in detail with reference to the accompanying drawings. Note that the same numerals or symbols are assigned to the same elements throughout the description of the embodiment. 
         [0017]    An information output device according to the embodiment will be described below with reference to the drawings. 
         [0018]    As shown in  FIG. 1 , an information output device  1  according to the embodiment acquires model information of a communication terminal  2  through communication with the communication terminal  2 . The model information includes a model name, performance, a use period, etc. of the communication terminal  2 . 
         [0019]    Communication with the communication terminal  2  is performed by, for example, a near field communication (NFC) panel  40  for which a near field wireless communication interface is included in the information output device  1  and a near field wireless communication interface included in the communication terminal  2 , which performs non-contact communication conforming to NFC. NFC is an international standard for near field wireless communication. 
         [0020]    For description of the embodiment, it is assumed that a user possessing the communication terminal  2  is visiting a shop dealing with the communication terminal  2 . 
         [0021]    When the user places the communication terminal  2  over the NFC panel  40  included in the information output device  1  installed at the shop, the information output device  1  reads the model information (model name, performance, use period. etc.) of the communication terminal  2 . 
         [0022]    Based on the read information on the use period of the communication terminal  2 , the information output device  1  outputs explanatory information on functions of the communication terminal  2  that the user currently possesses or on functions of other related models. Details will be described later. 
         [0023]    Next, an external structure of the information output device  1  according to the embodiment will be described. As shown in  FIG. 1 , the information output device  1  according to the embodiment includes a housing  20  having an overall shape of a substantially rectangular box. 
         [0024]    Note that, when the housing  20  is placed on a table or the like, the upward direction (upper side) is referred to as “upward direction (upper side)” and the side of a screen  23  is referred to as front (front side) while the opposite side is referred to as back (back side) in the following description. The screen  23  will be described later. 
         [0025]    The housing  20  includes a lateral plate  21  covering all sides of the housing  20  and an opening in the upward direction. 
         [0026]    Note that, in  FIG. 1 , although a position of a transparent part  221  is shown, the transparent part  221  itself is not shown. As for a drawing including the transparent part  221 ,  FIG. 2  is to be referred to. 
         [0027]    As shown in  FIG. 2 , a panel  22  is attached to the opening. The panel  22  includes, in the center thereof, the transparent part  221  that transmits light. Parts other than the transparent part  221  are made to hide the inner part of the housing  20  by, for example, being printed in black. 
         [0028]    Note that the panel  22  includes a transparent flat plate made of resin and is made to shield light by being printed in black or the like in parts other than the transparent part  221  on the surface facing the inner side of the housing  20 . However, this printing in black or the like is not a requirement and the entire part of the panel  22  may be the transparent part  221 . 
         [0029]    Also, a right lateral plate  211  (one side) of the housing  20  is provided with a slit-shaped inlet and a left lateral plate  212  (the other side) is provided with a slit-shaped outlet. 
         [0030]    Furthermore, the front of the housing  20  is provided with the NFC panel  40  that communicates with the communication terminal  2 . Near field wireless communication with the communication terminal  2  is made possible via this NFC panel  40 . 
         [0031]    As shown in  FIG. 2 , a projection unit  24 , which generates projection light and projects the light toward the back of the housing  20 , is provided substantially in the center of the inner part of the housing  20 . In the back of the housing  20 , a first minor  25  having a concave reflecting surface is provided such that the projection light from the projection unit  24  is reflected to a second mirror  27  having a flat reflecting surface and that the projection light reflected by the second mirror  27  is then reflected onto the screen  23 . 
         [0032]    Therefore, the projection light (image) LB 1  emitted from the projection unit  24  is reflected downward by the first mirror  25  and then reflected upward by the second minor  27  to pass through the transparent part  221  of the panel  22  and to be projected onto the screen  23  (projection light LB 2 ) provided outside the housing  20 . 
         [0033]    The screen  23  for showing the projected image is turnably supported by a screen mounting part  26 . The screen  23  can be in an upright position when in use and be folded down to the side of the housing  20  when not in use. 
         [0034]    (Configuration of Information Output Device) 
         [0035]      FIG. 3  is a block diagram showing a functional configuration of the information output device  1 . As shown in  FIG. 3 , the information output device  1  includes a control unit  10 , an operation unit  11 , a display unit  12 , a storage  13 , an interface (hereinafter referred to as I/F  14 ), another interface (hereinafter referred to as I/F  15 ), a voice output unit  16 , and a near field wireless communication unit  17 . 
         [0036]    Note that the information output device  1  is connected to an output unit  3  via the I/F  14 , a human body sensor SE via the I/F  15 , the NFC panel  40  via the near field wireless communication unit  17 , and a speaker  4  via the voice output unit  16 . 
         [0037]    Although not shown, the control unit  10  includes a central processing unit (CPU), a random access memory (RAM), etc. The CPU in the control unit  10  reads a program stored in a program storage  131  of the storage  13 , deploys the program in a work area of the RAM, and executes various processing including information output processing according to the deployed program. The information output processing will be described later. The RAM in the control unit  10  is a volatile memory and has a work area for storing various programs executed by the CPU or data related to these programs, etc. 
         [0038]    The operation unit  11  includes various function keys, cursor keys and the like, accepts key inputs by users, and outputs operation information on the key inputs to the control unit  10 . 
         [0039]    The display unit  12  includes a liquid crystal display (LCD) or the like and displays various information according to display control signals from the control unit  10 . 
         [0040]    The storage  13  includes a hard disk drive (HDD) or a nonvolatile semiconductor memory. The storage  13  further includes the program storage  131  and a video data storage  132 . 
         [0041]    The program storage  131  stores a system program and various processing programs executed by the control unit  10 , data required for execution of these programs, etc. The programs are stored in the program storage  131  in the form of computer-readable program codes. The control unit  10  sequentially executes operations according to the program codes. 
         [0042]    The video data storage  132  stores video data of video content. The video data includes projection images of respective frames (frame images) included in moving image data and voice data corresponding to the respective frames. The video data storage  132  stores the plurality of projection images, where orientations of a projection object are different, for each frame included in the video content. 
         [0043]    The I/F  14  is connected to the output unit  3  and transmits or receives data to or from the output unit  3 . 
         [0044]    The I/F  15  is connected to human body sensors SE 1  to SEn and transmits or receives data to or from the sensors. Communication with the human body sensors SE 1  to SEn may be performed either in a wired or wireless manner. 
         [0045]    The voice output unit  16  connected to the speaker  4  converts the voice data designated by the control unit  10  into voice signals and outputs the voice signals from the speaker  4 . 
         [0046]    The near field wireless communication unit  17  is a near field wireless communication interface in conformity to the international standard of near field wireless communication: NFC. The near field wireless communication unit  17  reads the model information of the communication terminal  2  including the model name and the use period through near field wireless communication. 
         [0047]    The output unit  3  is, for example, a projector (the projection unit  24  in  FIGS. 1 and 2 ) and a projection apparatus of a rear projection type that projects the video content from a back surface of the screen based on the projection image transmitted from the information output device  1 . As for the output unit  3 , for example, a digital light processing (DLP (registered trademark)) projector using a digital micromirror device (DMD) may be employed. The DMD performs, based on the projection image, a display action through individual high-speed on-off actions of respective tilt angles of multiple micromirrors (1024 pixels by 768 pixels for XGA) aligned in an arrayed manner, thereby forming an optical image from the reflected light. Turning on the micromirros in positions corresponding to an area of the projection object in the projection image and turning off the rest of the micromirrors in other areas allows for projecting only the projection object on the screen. 
         [0048]    As for the human body sensors SE 1  to SEn, for example, sensors, which can detect a human existence within a detection area by detecting a change in an ambient temperature using infrared rays or the like, may be employed. When detecting the human existence, the human body sensors SE 1  to SEn report to the control unit  10  to turn on power of the information output device  1  via the control unit  10 . Also when the human body sensors SE 1  to SEn do not detect a human existence for a certain period of time after use of the information output device  1 , the human body sensors SE 1  to SEn report to the control unit  10  for transition of the information output device  1  to a power saving mode via the control unit  10 . 
         [0049]      FIG. 4  is a flowchart showing operations of the information output device  1  according to the embodiment. 
         [0050]    In the embodiment, a description is given for an example where a user is visiting a shop dealing with communication terminals such as smartphones, where the information output device  1  is installed, and receives an explanation from the information output device  1  instead of from a shop clerk. 
         [0051]    As shown in  FIG. 4 , the information output device  1  performs near field wireless communication with the communication terminal  2  via the near field wireless communication unit  17  and reads the model information when the user possessing the communication terminal  2  such as a smartphone places the communication terminal  2  over the NFC panel  40  of the information output device  1  (step S 101 ). 
         [0052]    Thereafter, the control unit (acquisition unit)  10  acquires information on the model name, use period, etc. of the communication terminal  2  from the model information having been read via the near field wireless communication unit  17  and stores the information in the storage  13  (step S 102 ). The information on the use period may be, for example, a use period stored in the communication terminal  2  or a date and time when the user started to use the communication terminal  2 . When the date and time when the user started to use the communication terminal  2  is acquired, the use period may be acquired through comparison with the current date and time. 
         [0053]    When the acquired information on the use period is less than a predetermined period (e.g. less than two years) (“NO” in step S 103 ), the control unit  10  acquires the information on the model name from the communication terminal  2  and then outputs, to the output unit  3  (output unit), information on performance, features, etc. of the model based on the acquired model name. 
         [0054]    Specifically, the control unit  10  converts, for the currently-used model, an explanation on major functions and features and information on convenient functions that general users are not aware of into image information via the I/F  14  and outputs the image information to the output unit  3  for projection onto the screen  23  while converting them into voice information via the voice output unit  16  for voice output from the speaker  4 . 
         [0055]    Note that a reason for assuming a period of less than two years here is because a use period of two years is typically specified upon signing a contract in the communication terminal distribution industry in general. Due to this, relatively a small number of users sign a new contract or change models in less than two years. Therefore, when the acquired information on the use period is less than the predetermined period (two years), a description is given on the major functions, etc. of the communication terminal  2  currently in possession. 
         [0056]    On the other hand, when the acquired information on the use period is equal to or more than the predetermined period (“YES” in step S 103 ), the control unit  10  acquires the information on the model name from the communication terminal  2 . 
         [0057]    Specifically, the control unit  10  acquires, from the storage  13 , information on performance of the major functions, etc. of a related model registered in association with the name of the currently-used model (for example, a new model such as a successor model of the currently-used model having major functions similar to those of the currently-used model). 
         [0058]    Thereafter, when another related (similar) model is available from the same distributor based on the acquired information on the model name (“YES” in step S 104 ), the control unit  10  outputs information on the other model (step S 105 ). 
         [0059]    Specifically, the control unit  10  has the information on the successor model of the same distributor projected to the output unit  3  and output in voice from the speaker  4 , thereby making an announcement where the differences in performance and functions between the currently-used model and the successor model are explained and advantages of a model change to the successor model are announced. 
         [0060]    Note that a reason for assuming the successor model of the same distributor here is because a user tends to change to a model having similar or superior functions to the communication terminal  2  that the user currently possesses and having operation methods similar to those of the communication terminal  2  that the user currently possesses, when the user changes models after using the current communication terminal  2  for two years or more. 
         [0061]    Note that when another model from the same distributor is not available (“NO” in step S 104 ), the control unit  10  outputs information on, for example, another model from the same distributor which is a recommended item on promotion, thereby making an announcement where functions of the model are explained and advantages of a model change are announced (step S 106 ). 
         [0062]    Note that the information output in step S 106  may be information on a popular model from a different distributor. 
         [0063]    As described above, according to the information output device  1  of the embodiment, there can be provided an information output device that outputs information based on usage status of the communication terminal  2  by the user through communication between the communication terminal  2  and the information output device  1  whereby the model information is acquired. 
         [0064]    Furthermore, use of the information output device  1  according to the embodiment, for example in a waiting time at the shop, allows the user to learn, in advance, information including that of the communication terminal  2  currently in possession or recommended models for a model change. This enhances understanding on items which may not be clear only from a written description in a brochure, thereby contributing to promotion of model changes to smartphones as a result. 
         [0065]    Moreover, since the information output device  1  gives a general explanation on the communication terminal  2 , the shop clerk is only required to follow up on the explanation and can mainly focus on purchase procedures. This results in higher investment effect. Also, a reduced burden on shop clerks and an improved turnover rate of attending customers can be expected. 
         [0066]    Note that the embodiment has been described with the premise that the communication is performed by using near field wireless communication conforming to the NFC standard. However, the communication is not limited thereto and may use another standard for near field wireless communication such as Bluetooth (registered trademark) or wireless LAN. 
         [0067]    Although the present invention has been described above with the embodiment, it shall be understood that the technical scope of the invention is not limited to the scope described for the above embodiment. It is apparent to those skilled in the art that various modifications or improvements can be applied to the embodiment. It is also apparent from the descriptions of claims that an embodiment including such modifications or improvements is also within the technical scope of the invention.
