     BACKGROUND 
     During the operations involved with erecting a building, or other structure, there are a wide variety of tasks performed every day which utilize positioning information and positioning tools. This includes moving soil, pouring foundations and footers, erecting walls and roofs, and installing interior systems such as HVAC, plumbing, electrical, sprinklers, as well as interior walls and finishing. Typically, these are manually performed operations using tape measures, electronic layout tools (e.g., plumb lasers and digital levels), distance meters, and even survey-type instruments. These tools are used to layout the dimensions of the structures being built. Additionally, these layout tools are often operated by a single user who marks the position of a particular feature while another user installs or builds the feature at the marked position. For example, an operator of an electronic plumb laser marks positions on a wall where holes are to be drilled. Later, another worker actually drills the holes at the indicated positions. 
     When a project is completed, the final construction drawings are generated which are intended to show where features of a building are actually located. For example, during the course of erecting a building, pipes may have to be re-routed around a structural member. As a result, the actual building is not reflected in the original construction drawings. When this is not shown on the original construction drawings, they are amended on the fly so that they show the features of the building as built. Again, this is often performed manually so that the final construction drawings are an accurate representation of the building as completed. 
     SUMMARY 
     A method of automated handheld tool task verification is disclosed. In one embodiment, at least one operating parameter for performing a task is received at a handheld tool. It is then verified at the handheld tool that it is configured with the at least one operating parameter. The handheld tool then generates data verifying that the task was performed in accordance with the at least one operating parameter.

     Information Management Network 
       FIG. 1  shows an information management network  100  in accordance with an embodiment. In  FIG. 1 , an information management system  101 , comprising computer  102  and database  103 , receives asset information (e.g., asset report  111 ) from a reporting source  110 . In response to user requests, in response to the occurrence of a defined event, or automatically based upon a pre-determined time interval, report generator  106  of information management system  101  generates reports  150  to positioning infrastructure  140 . Similarly, reporting source  110  can generate asset report  111  in response to user requests, in response to the occurrence of a defined event, or automatically based upon a pre-determined time interval. In accordance with various embodiments, task data  131  comprises data describing events, conditions, and parameters which are recorded at a site. For example, handheld tool  120  can be used to report operating parameters which were implemented upon handheld tool in the performance of a task. Similarly, handheld tool  120  can record the condition of an item such as a structure, a tool, etc. back to information management system  101 . It is noted that the recording, and reporting, of this information can occur in real-time, and can include conditions before, during, and after a task have been performed. This information can be used to verify that operations performed by handheld tool  120  were performed in accordance with pre-determined parameters and can show the condition of the finished task. In general, reports  150  comprise data, warnings, or other messages which assist in the completion of a task. In one embodiment, positioning infrastructure  140  can generate position data  141  in response to report  150  which is used to assist an operator in positioning and orienting handheld tool  120  at the correct location to perform a particular task. In one embodiment, user interface  130  is used to direct the operator in positioning and orienting handheld tool  120 . It is noted that information management network  100 , as well as components thereof such as information management system  101 , can be implemented in a cloud computing environment in accordance with various embodiments. 
     In accordance with one embodiment, database  103  can store and retrieve task data  131  and use that data to generate reports  150 . The reports  150  can be used to convey details of a task to be performed such as the position where the task is to be performed, operating parameters when performing the task, alerts, updated scheduling information, or updated blueprints  105  based upon received task data  131 , etc. For example, report  150  may comprise a data file (e.g., a computer-aided design (CAD) file), or other building information modeling data, which shows the location within a room where certain tasks, such as drilling holes, are to be performed. Using this information, positioning infrastructure  140  can generate cues which the operator of handheld tool  120  uses to properly place the working end (e.g., the drill bit) at the correct location to drill a hole. Positioning infrastructure  140  can also generate cues which direct the operator to change the alignment/orientation of handheld toot  120  so that the hole is drilled in the proper direction. As a result, separate steps of laying out and marking the positions where operations are to be performed, as welt as performing the actual operation itself, can be performed by a single operator in one step. Positioning infrastructure  140  is also configured to determine how far handheld tool  120  has travelled while performing a task, such as drilling a hole, and can generate a message telling the operator of handheld tool  120  to stop drilling when the hole is sufficiently deep. Alternatively, the message from positioning infrastructure  140  can cause handheld tool  120  to automatically shut down when a task is completed. In another embodiment, this message can be generated by information management system  101 . This is possible in part because handheld tool  120  is configured with a tool position detector  121 . As will be discussed in greater detail below, tool position detector  121  is configured to determine the position of the working end of handheld tool  120  based upon a local, or global reference system. Additionally, tool position detector  121  can be configured to determine the alignment/orientation (e.g., azimuth and tilt) of handheld tool  120 . Alternatively, tool position detector  121  is coupled with positioning infrastructure  140  rather than with handheld tool  120 . 
     Upon completion of a task, task data  131  is sent from handheld tool  120  to a reporting source  110 . Reporting source  110  then generates an asset report  111  to information management system  101  which facilitates tracking the progress of work at the construction site and automatically updating records such as blueprints  105  in real-time using record updater  107  so that they reflect the as-built configuration of the building. It is noted that the functions described which are attributed to positioning infrastructure  140 , tool position detector  121 , user interface  130  and reporting source  110  can be implemented in a variety of configurations. In one embodiment, all of these functions are integrated into a single device. This device can be coupled with, mounted upon, or integrated within handheld tool  120 . In another embodiment, some of the above functions (e.g., reporting source  110 , positioning infrastructure  140 , and/or user interface  130  can be integrated into a handheld device such as a personal computer system, personal digital assistant (PDA), a “smart phone”, or a dedicated device. This device is in communication with handheld tool  120  which further comprises tool position detector  121  and, optionally, an additional user interface  130 . It is noted that a plurality of handheld tools  120  can send task data to a reporting source  110  in accordance with one embodiment. Similarly, a plurality of handheld tools  120  can receive position data  141  from a single positioning infrastructure in accordance with one embodiment. 
     Additionally, information management system  101  can prevent inadvertent damage to structures within a building. As an example, blueprints  105  can contain information such as the location of mechanical, electrical, and plumbing features (e.g., pipes, electrical conduits, ventilation ducts, etc.) which have already been built, or will be later. Because asset report  111  provides real-time data on actions performed at a construction site, information management system  101  can determine whether an operator of handheld tool  120  is performing an action which may damage other structures or interfere with the installation of subsequent structures. Information management system  101  can generate a warning (e.g., report  150 ) to the operator of handheld tool  120  prior to beginning a task so that the operator is aware of the potential damage that could be caused. In one embodiment, positioning infrastructure  140 , and information management system  101 , can monitor the position of handheld tool  120  in real-time and generate a message which causes handheld tool  120  to automatically shut down to prevent damaging other structures. Additionally, user interface  130  can display, for example, a picture of a all with the underlying structures overlaid to represent their positions, or a blueprint of the wall with the same information. Again, this means that separate steps of laying out and marking the locations of existing structures are not necessary as the operator of handheld tool  120  can be provided that information directly. 
     Furthermore, due to the asset management capabilities described herein a significant business management tool is realized. That is, because information management system  101  is useful at all levels of asset management, the information management system  101  provides significant value added features. For example, the asset reports  111  can provide real-tune reporting on the progress of a particular task to allow changing the workflow implemented at a construction site. Information management system  101  can also be used to track the maintenance schedule of handheld tool  120 , monitor the performance of handheld tool  120 , and to track. the service of “consumables” such as drill bits and saw blades. Furthermore, this can be linked with the material being worked upon. For example, knowing whether concrete or steel is being drilled can significantly change the parameters regarding the life of the consumables, safety, and operator performance, as well whether work is progressing at a satisfactory pace and/or whether to generate alerts. 
     As an example, if asset report  111  indicates that it is taking longer than expected to drill holes using handheld tool  120 , information management system  101  can determine whether the drill bit being used by handheld tool  120  is in need of replacement, or if handheld tool  120  itself is in need of maintenance. Determination of how long it takes to perform a task can be based upon, for example, the start time and finish time for a task as reported by handheld tool  120 , or the distance handheld tool  120  has moved in performing a task as reported by positioning infrastructure  140 . Additionally, as the location of the consumables and handheld tools can be monitored by information management system  101 , the process of locating them in order to implement needed repairs is facilitated. This may also include maintaining inventory of consumables so that sufficient stores are maintained at the construction site to prevent unnecessary delays. Alternatively, it may be that an operator of handheld tool  120  is not exerting enough force which causes the drilling of holes to take longer than expected. In one embodiment, information management system  101  can make this determination and generate a report  150  in real-time to the operator of handheld tool  120  which explains that more force should be exerted upon handheld tool  120 . Additionally, information management system  101  can ensure that the proper tools, personnel, and other assets are at the correct location at the correct time to perform a particular task. As an example, information management system  101  can ensure that a generator is at the construction site to provide power to handheld tool  120  as well as the correct fasteners for a particular task. This data can also be used to track the life of handheld tools, consumables, etc., from various providers to determine which provider provides a superior product. For example, if drill bits from one provider have a service life 20% lower than those from a second provider, it may indicate that the second provider sells a superior product. 
     In another embodiment, information management system  101  can monitor workplace safety in real-time. For example, database  103  can maintain a record of what handheld tools a particular operator is allowed to use. In one embodiment, for example user interface  130  can identify an operator via manual login (such as by operator input of a personally identifying code), automatic electronic login (such as by sensing an personally identifying information provided wirelessly by an RFID badge worn by the employee), or combination thereof. Thus, if the operator has not been trained how to operate a particular handheld tool, workplace safety, or other relevant information, information management system  101  can generate a report  150  which indicates this to the operator. In one embodiment, report  150  may disable handheld tool  120  such that the operator cannot use handheld tool  120  until the required training has been recorded in database  103 . Furthermore, information management system  101  can be used to monitor how quickly a particular operator is at performing a task. This information can be used to determine whether additional training and/or supervision is need for that particular operator. In various embodiments, additional sensor devices (e.g., sensors  550  of  FIGS. 5A-5C ) can be worn by a user and interact with handheld tool  120 . Examples of such sensors include, but are not limited to, sensors for recording vibration, dust, noise, chemicals, radiation, or other hazardous exposures which can be collected and reported to information management system  101  to be used as a record against possible health claims. 
     Additionally, information management system  101  can be used to monitor the quality of work performed at a construction site. As will be discussed in greater detail below, various sensors can be used to send task data  131  which provide metrics (e.g., operating parameters of handheld tool  120  during the performance of a task) for determining how well various operations have been performed. For example, a sensor coupled with handheld tool  120  can determine how much torque was applied to a fastener. This information can be used by, for example, building inspectors to assist them in assessing whether a building is being built in accordance with the building codes. In another example, a camera coupled with handheld tool  120  can capture an image, images, or video showing the work before, during, and after it is performed. The captured media can verify that the hole was cleanly drilled, did not damage surrounding structures, and that excess material was removed. Furthermore, asset report  111  can not only report what actions have been performed at the construction site, but can also report what materials were used or applied to complete a particular task. Asset report  111  can also be used to notify in real-time whether materials, or consumables, are being used at a greater than expected rate. For example, an operator can generate an asset report via user interface  130  which states that a given material (e.g., an adhesives is not in stock at the construction site. 
     With reference now to  FIG. 2 , all or portions of some embodiments described herein are composed of computer-readable and computer-executable instructions that reside, tier example, in computer-usable/computer-readable storage media of a computer system. That is,  FIG. 2  illustrates one example of a type of computer system (computer  102  of  FIG. 1 ) that can be used in accordance with or to implement various embodiments which are discussed herein, it is appreciated that computer system  102  of  FIG. 2  is only an example and that embodiments as described herein can operate on or within a number of different computer systems including, but not limited to, general purpose networked computer systems, embedded computer systems, server devices, various intermediate devices/nodes, stand atone computer systems, handheld computer systems, multi-media devices, and the like.

As depicted in  FIG. 2 , computer system  102  is also well suited to a multi-processor environment in which a plurality of processors  206 A,  206 B, and  206 C are present. Conversely, computer system  102  is also well suited to having a single processor such as, for example, processor  206 A. Processors  206 A,  206 B, and  206 C may be any of various types of microprocessors. Computer system  102  also includes data storage features such as a computer usable volatile memory  208 , e.g., random access memory (RAM), coupled to bus  204  for storing information and instructions for processors  206 A,  206 B, and  206 C. Computer system  102  also includes computer usable non-volatile memory  210 , e.g., read only memory (ROM), and coupled to bus  204  for storing static information and instructions for processors  206 A,  206 B, and  206 C. Also present in computer system  102  is a data storage unit  212  (e.g., a magnetic or optical disk and disk drive) coupled to bus  204  for storing information and instructions. Computer system  102  also includes an optional alphanumeric input device  214  including alphanumeric and function keys coupled to bus  204  for communicating information and command selections to processor  206 A or processors  206 A,  206 B, and  206 C. Computer system  102  also includes an optional cursor control device  216  coupled to bus  204  for communicating user input information and command selections to processor  206 A or processors  206 A,  206 B, and  206 C. In one embodiment, computer system  102  also includes an optional display device  218  coupled to bus  204  for displaying information.

Optional cursor control device  216  allows the computer user to dynamically signal the movement of a visible symbol (cursor) on a display screen of display device  218  and indicate user selections of selectable items displayed on display device  218 . Many implementations of cursor control device  216  are known in the art including a trackball, mouse, touch pad, joystick or special keys on alphanumeric input device  214  capable of signaling movement of a given direction or manner of displacement. In another embodiment, a motion sensing device (not shown) detect movement of a handheld computer system. Examples of a motion sensing device in accordance with various embodiments include, but are not limited to, gyroscopes, accelerometers, tilt-sensors, or the like. Alternatively, it will be appreciated that a cursor can be directed and/or activated via input from alphanumeric input device  214  using special keys and key sequence commands. Computer system  102  is also well suited to having a cursor directed by other means such as, for example, voice commands. In another embodiment, display device  218  comprises a touch screen display which can detect contact upon its surface and interpret this event as a command. Computer system  102  also includes an I/O device  220  for coupling computer system  102  with external entities. For example, in one embodiment, I/O device  220  is a modem for enabling wired or wireless communications between system  102  and an external network such as, but not limited to, the Internet. 
     Referring still to  FIG. 2 , various other components are depicted for computer system  102 . Specifically, when present, an operating system  222 , applications  224 , modules  226 , and data  228  are shown as typically residing in one or some combination of computer usable volatile memory  208  (e.g., RAM), computer usable non-volatile memory  210  (e.g., ROM), and data storage unit  212 .

       FIG. 3  shows information management network  100  in accordance with an embodiment. As shown in  FIG. 3 , reporting source  110  receives data such as task data  131  from a handheld tools  120 -A,  120 -B,  120 -C 3 - 120 -n. In accordance with various embodiments, positioning infrastructure  140  can generate data to a plurality of handheld tools  120  based upon information received via reports  150 . 
     Similarly, reporting source  110  can also receive data from other sources such as operator(s)  310 , consumables  320 , materials  330 , and other assets  340 . Identification of these various data sources can be detected and reported automatically, or manually by operator  310  via user interface  130 . In accordance with various embodiments, reporting source  110  can comprise a dedicated user interface  130 , and other data sensing devices such as, but not limited to, radio-frequency identification (RFID) readers, magnetic card readers, barcode readers, or image capture devices which utilize image recognition software o identify objects. In accordance with one embodiment, assets  340  comprise devices such as air compressors, extension cords, batteries, equipment boxes, fire extinguishers, or other equipment which are used at the construction site. As a result, information management system  101  can integrate data from a variety of sources in order to facilitate workflow, monitor performance, update blueprints  105  on areal-time basis, and generate reports based upon the received information. 
       FIG. 4  is a flowchart of a method  400  for managing information at a construction site in accordance with one embodiment. The flow chart of method  400  includes some procedures that, in various embodiments, are carried out by one or more processors under the control of computer-readable and computer-executable instructions. In this fashion, procedures described herein and in conjunction with the flow chart of method  400  are, or may be, implemented in an automated fashion using a computer, in various embodiments. The computer-readable and computer-executable instructions can reside in any tangible, non-transitory computer-readable storage media, such as, for example, in data storage features such as peripheral computer-readable storage media  202 , RAM  208 , ROM  210 , and/or storage device  212  (all of  FIG. 2 ) or the like. The computer-readable and computer-executable instructions, which reside on tangible, non transitory computer-readable storage media, are used to control or operate in conjunction with, for example, one or some combination of processor(s)  206  (see  FIG. 2 ), or other similar processor(s). Although specific procedures are disclosed in the flow chart of method  400 , such procedures are examples. That is, embodiments are well suited to performing various other procedures or variations of the procedures recited in the flow chart of method  400 . Likewise, in some embodiments, the procedures in the flow chart of method  400  may be performed in an order different than presented and/or not all of the procedures described may be performed. It is further appreciated that procedures described in the flow chart of method  400  may be implemented in hardware, or a combination of hardware with firmware and/or software. 
     In operation  410  of  FIG. 4 , task data is received from a handheld tool at construction site. As described above, handheld tool  120  is configured to generate task data which is sent via reporting source  110  to information management system  101 . 
     In operation  420  of  FIG. 4 , a database is populated with the task data such that the task data can be retrieved from the database. In one embodiment, task data  131  is received in asset report  111 . This data can be stored in database  103  for later use such as to generate reports  150 . The task data  131  can also be used to automatically update blueprints  105  to reflect the as-built configuration of a building or other structure. The term “as-built” means the actual configuration of features within the building which may, or may not, differ from the original blueprints. For example, a pipe may have to be routed around a beam in the original blueprints. However, as the building is being constructed, it is discovered that the pipe in fact does not have to be routed around the beam. Thus, the as-built configuration found in the updated blueprints shows he location of the pipe which was not routed around the beam. In accordance with various embodiments, the location, disposition, and configuration of structural elements, or other components, at a construction site cat be recorded and reported using information management network  100 . For example, handheld tool  120 , positioning infrastructure  140 , or reporting source  110  can be configured to report the completion of tasks, including parameters implemented in the completion of those tasks, to information management system  101 . 
     In operation  430  of  FIG. 4 , the task data is used to generate at least one report. In accordance with one embodiment, the task data  131  is used to update records at information management system  101 . As a result, report  150  can generate instructions, messages, warnings, or the like based upon real-time conditions at the building site. 
     Example Configurations of Components of Information Management Network 
       FIGS. 5A, 5B, and 5C  show different configurations of components of information management network, in accordance with various embodiments. It is noted the configurations shown in  FIGS. 5A, 5B, and 5C  are for purposes of illustration only and that embodiments of the present technology are not limited to these examples alone. In  FIG. 5A , an operator device  510  (e.g., handheld tool  120 ) comprises reporting source  110 , user interface  130 , tool position detector  121 , positioning infrastructure  140 , and sensors  550 . 
     In accordance with one embodiment, operator device  510  is a stand-alone device coupled with a housing  520 . In accordance with various embodiments, housing  520  is comprised of a rigid or semi rigid material or materials. In one embodiment, all or a portion of housing  520  is made of an injection molded material such as high impact strength polycarbonate. In one embodiment, housing  520  is transparent to global navigation satellite system (GNSS) satellite signals such as signals which can be received by tool position detector  121  and/or positioning infrastructure  140 . In the embodiment of  FIG. 5A , operator device  510  is configured to be coupled with handheld tool  120 . For example, operator device  510  can be removably coupled with handheld tool  120  using, a clip-on bracket. In another embodiment, operator device  510  can be coupled with handheld toot  120  using mechanical fasteners such as screws. While not shown in  FIG. 5A , when operator device  510  is configured as a stand-alone device it is powered by a battery. 
     In another embodiment, operator device  510  comprises an integral component of handheld tool  120 . In this embodiment, housing  520  comprises the housing of handheld tool  120  itself. In one embodiment, operator device  510  can draw power directly from handheld tool  120 . 
     In accordance with various embodiments, sensors  550  comprise devices which collect information for operator device  510 . Examples of sensors  550  include, but are not limited to, an image capture device (or plurality thereof), a depth camera a laser scanner, an ultrasonic ranging device, a laser range finder, a barcode scanner, an RFID reader, or the like. Sensors  550  may also identify an operator via wireless communication with an operator identification device (e.g., a badge with an RFID coded with opera or unique information). A barcode scanner, or RFID reader, can be used to quickly identify objects, or consumables used by handheld tool  120 . For example, each drill bit, saw blade, or other consumable can be configured with a barcode, or RFID tag, which provides a unique identifier of that object. Using this information, operator device  510  can access information which correlates that identifier with other characteristics of that object. As an example, a drill bit can be provided with an RFID tag providing a unique identifier to operator device  510 . Operator device  510  then accesses a local, or remote, database and determines that the identified object is a ¾ inch drill bit which is 8 inches long. This information can be used by operator device  510  to facilitate properly performing a task as well as provide information which can be included in task data  131  which is forwarded to information management system  101 . In one embodiment, operating parameters of operator device  510  can be configured, either manually or automatically, based upon information from report  150  from information management system  101 . This information can be used by the operator of handheld tool  120  to verify that he is using the correct drill bit, as well as for later verification that the task was performed up to standard. Also, data can be sent from operator device  510  conveying its settings or operating parameters back to information management system  101 . A user of information management system  101  can also use this information to track the use of that drill bit to determine whether it is time to replace it. In another example, sensors  550  can verify that the correct type of fire-proofing material was used by the operator of handheld tool  120 . The use of a camera allows an operator of handheld tool  120  to capture an image of the work performed to verify that the task was performed correctly such as at the correct location and in a manner which complies with applicable standards. It is noted that a plurality of operator devices  510  can be communicatively coupled in a mesh network to permit communications between a plurality of handheld tools  120 . Thus, in one embodiment, one handheld tool  120  can relay information to a second handheld tool  120 . Operator device  510  can also determine and forward information regarding what materials were used to perform a task (e.g., what type of fastener was used), as well as parameters about the task which was performed such as the torque applied to a nut, or the force used to drive an anchor into a substrate. Operator device  510  can also provide real-time metrics during the course of the task being performed. This permits remote monitoring and/or control of the process from another location such as from information management system  101 . 
     In  FIG. 5B , operator device  510  comprises reporting source  110 , user interface  130 , tool position detector  121 , and sensors  550 . A separate building site device  530  comprising positioning infrastructure  140  is located in the vicinity of operator device  510 . Positioning infrastructure  140  comprises sensors, wired and wireless communication components, processors, and software instructions which are disposed in a housing  540  and which facilitate building site device  530  in generating instructions to operator device  510 . A more detailed description of these components follows with reference to  FIG. 6 . 
     In accordance with various embodiments, building site device  530  is configured to receive report(s)  150  from information management system  101  and to relay some or all of this information to operator device  510 . In accordance with various embodiments, building site device  530  can be precisely placed at a set of coordinates in the vicinity of the construction site. By determining the azimuth, direction, and elevation from building site device  530  to other points, building site device  530  can provide positioning cues to operator device to assist an operator in properly placing handheld tool  120  to perform a task. This is possible in part because building site device  530  receives instructions via report  150  such as blueprints  105 . Building site device  530  can correlate the features shown in blueprints  105  with its current position to determine where those features are to be located at the building site. Furthermore, avoidance zones can be defined where certain actions are not permitted. For example, if rebar is embedded 6 inches deep within a concrete pillar, it may be permissible to drill down 2 inches into the pillar above the rebar, but no deeper to prevent inadvertently hitting the rebar. It may be necessary to use a certain type of adhesive for a task based upon the substances being glued. In accordance with embodiments of the present technology, this information can be sent to operator device  510  through information management network  100 . 
     As an example, building site device  530  can be placed in a space of a building where a room is being built. Using, for example, a GNSS receiver, building site device  530  can precisely determine its own geographic position. Using the information from blueprints  105 , building site device  530  can then determine where features of that room are to be located. For example, building site device  530  can determine the location and distance to the walls of the room being built, as well as other features such as pipes, conduits, structural members and the like which will be disposed in the space behind the wall. It is important for an operator of handheld tool  120  to know the location of these features as well in order to prevent inadvertent damage, or to perform tasks which are intended to tie in with these features. For example, it may be desired to drill through sheetrock into underlying studs in a wall. Building site device  530  can determine where these features are located relative to its own position by leveraging the knowledge of its own position and the data from blueprints  105 . 
     In accordance with various embodiments, building site device  530  is also configured to detect the position and/or orientation of handheld tool  120  and to generate instructions which facilitate correctly positioning and orienting it to perform a task. For example, if a hole is to be drilled in a floor, building site device  530  can access blueprints  105  and determine the location, angle, and desired depth of that hole and correlate that information with the location and orientation of handheld tool  120 . Building site device  530  then determines where that hole is to be located relative its own location. Building site device  530  then generates one or more messages to operator device  510  which provide positioning cues such that an operator of handheld tool  120  can correctly position the working end (e.g., the drill bit tip) at the location where the hole is to be drilled. It is noted that a series of communications between building site device  530  and operator device  510  may occur to correctly position the working end of handheld tool  120  at the correct location. 
     Additionally, building site device  530  may use position and/or orientation information generated by tool position detector  121  to facilitate the process of positioning and orienting handheld tool  120 . In one embodiment, once the working end of handheld tool  120  is correctly positioned, building site device  530  can generate one or more messages to facilitate correctly orienting handheld tool  120 . This is to facilitate drilling the hole at the correct angle as determined by blueprints  105 . It is noted that these actions can be performed by operator device  510  of  FIG. 5A  as described above. In accordance with various embodiments, multiple building site devices  530  can be positioned at a construction site which are communicatively coupled with each other in a mesh network and with one or more handheld tools  120 . It is noted that in one embodiment, user interface  130  comprises an operator wearable transparent display which projects data, such as the location of hidden structures (e.g., pipes or rebar to the operator. For example heads-up display (HUD) glasses exist which use an organic light emitting diode (OLED) to project data for a wearer. In one embodiment, a wearer of these glasses can see a projection of objects which the operator may want to avoid such as rebar, as well the position at which a task is to be performed. For example, if a hole is to be drilled at a certain location, that location can be projected onto the glasses so that when a user is looking at a wall, the position where the hole will be drilled is displayed by the glasses at the proper location on the wall. Building site device  530  can provide data or images which are projected or displayed directly by a LED or laser projector, or by such HUD glasses, and additionally such HUD glasses may serve a dual purpose of providing eye protection (e.g., as safety glasses) for an operator when operating an handheld tool. 
     In  FIG. 5C , operator device  510  comprises a user interface  130 , tool position detector  121 , and sensors  550  while building site device  530  comprises reporting source  110 , user interface  130 , and positioning infrastructure  140 .  FIG. 5C  represents an embodiment in which the functions of reporting source  110  and positioning infrastructure  140  are removed from the operator of handheld tool  120 , or from handheld tool  120  itself. In one embodiment, building site device  530 , as represented in  FIGS. 5B and 5C , can provide positioning and/or orientation information to a plurality of operator devices  510 . It is noted that in accordance with various embodiments, user interface  130  may be configured differently. For example, in one embodiment, user interface  130  comprises a touch screen display which is capable of displaying characters, menus, diagrams, images, and other data for an operator of handheld tool  120 . In another embodiment, user interface may comprise an array of LED lights which are configured to provide visual cues which facilitate positioning the working end of handheld tool  120  at a given position and the alignment of handheld tool  120  as well. In one embodiment, the display of visual cues is in response to messages generated by building site device  530  and/or operator device  510 . 
     There are a variety of instruments which can be configured to serve the function of building site device  530 . One example instrument which can be configured to perform the functions of building site device  530  is a pseudolite which is used to provide localized position information, such as GNSS signal data to operator device  510 . Another example instrument which can be configured to perform the functions of building site device  530  is a robotic total station. One example of a robotic total station is the S8 Total station which is commercially available from Trimble Navigation Limited of Sunnyvale, California. Another example of an instrument which can be configured to perform the functions of building site device  530  is a virtual reference station (VRS) rover which uses networked real-time kinematics corrections to determine its location more precisely. One example of a VRS rover is the R8 VRS which is commercially available from Trimble Navigation Limited of Sunnyvale, Calif. 
     Example Positioning Infrastructure 
       FIG. 6  is a block diagram of an example positioning infrastructure  140  in accordance with one embodiment. In  FIG. 6 , positioning infrastructure  140  comprises sensors  610 , a data receiver  620 , one or more communication transceivers  630 , an antenna  640 , and a power source  650 . In accordance with various embodiments, sensors  610  a configured to detect objects and features around positioning infrastructure  140 . Some objects include, but are not limited to, handheld tool  120 , operators  310 , consumables  320 , materials  330 , and assets  340  as described in  FIG. 3 . Sensors  610  are also configured to detect objects pertaining to a construction site such as buildings, wall, pipes, floors, ceilings, vehicles, etc. Sensors  610  further comprise devices for determining the position of positioning infrastructure  140  such as a GNSS receiver (e.g., GNSS receiver  1000  of  FIG. 10 ), radio receiver(s), and the like. In another embodiment, the position of positioning infrastructure  140  can be manually entered by an operator using a user interface  130  coupled therewith. It is noted that other objects and features described above can also be manually entered via user interface  130  as well. Examples of sensors  610  in accordance with various embodiment include, but are not limited to, an image capture device, or plurality thereof, an ultrasonic sensor, a laser scanner, a laser range finder, barcode scanner, an RFID reader, sonic range finders, a magnetic swipe card reader, a radio ranging device, or the like. It is noted that information received via communication transceiver(s)  630  can also be used to detect and/or identify features and objects as well. In accordance with one embodiment, photogrammetric processing of a captured image (e.g., by information management system  101 , or positioning infrastructure  140 ) can be used to detect and/or identify features and objects. 
     In one embodiment, the location of cameras for photogrammetric processing can be determined by information management system  101  based upon what task is to be performed. For example, if a particular wall is to be drilled, information management system  101  can determine where to place cameras in order to capture images which facilitate photogrammetric processing to determine various parameters of the task being performed. Thus, the location where the working end of the drill bit, depth of drilling, angle of drilling, and other parameters can be determined using photogrammetric processing of images captures by sensors  610 . Alternatively, a user can choose where to place the cameras in order to capture images to be used in photogrammetric processing. It another embodiment, cameras can be placed in each corner of a room to capture images of the entire area. In accordance with one embodiment, positioning infrastructure  140  can calculate the respective positions of cameras within a work space by detecting known points from a BIM model. For example, I-beams, or room corners, can be readily identified and, based on their known position, the position of the cameras which have captured those features can be determined. Again, this processing of images, as well as other photogrammetric processing, can be performed by information management system  101  and/or positioning infrastructure  140 . 
     In accordance with one embodiment, when handheld tool  120  is brought into a workspace in which the cameras have been placed, it is captured by at least one camera and its position can be determined by image recognition and triangulation. The orientation of handheld tool  120  can be determined using multiple cameras to determine the roll, pitch, and yaw. Also, the position of the working end of handheld tool  120  can be processed in a similar manner. In accordance with one embodiment, this information can be conveyed to handheld tool  120  to provide real-time feedback to an operator of the position and orientation of handheld tool  120 . In one embodiment, the cameras comprising sensors  610  can view multiple handheld tools  120  simultaneously and provide real-time position and orientation information respective operators of those handheld tools. Additionally, new cameras can be added to adjacent or next work areas and integrated into existing area camera networks to facilitate moving handheld tool  120  to other areas, or to extend coverage of positioning infrastructure  140  in large areas where camera angle and/or range is not adequate. 
     Data receiver  620  comprises a computer system similar to that described above with reference to  FIG. 2 . In accordance with various embodiments, data receiver  620  receives reports  150 , or other data, and uses this information to generate messages to, for example, operator device  510 . As described above, reports  150  can convey CAD files, or other building information modeling data, which describes the location where various objects and structures are to be built at a construction site. Because positioning infrastructure  140  is aware of its own geographic position, it can correlate where these objects and structures are to be located relative to its own location in a local or global coordinate system. As an example, the angle and distance to each pixel in a captured image can be calculated by data receiver  620  in one embodiment. In accordance with various embodiments, positioning infrastructure  140  can generate messages and instructions to operator device  510  which assist in positioning and orienting handheld tool  120  to perform a task. It is noted that some components as described above with reference to  FIG. 2 , such as processors  206 B and  206 C, may be redundant in the implementation of data receiver  620  and can therefore be excluded in one embodiment. It is noted that information relating to settings of handheld tool  120  can be relayed via data receiver  620 . For example, leveraging knowledge of a material which is being worked on, information on the desired operating parameters (e.g., speed, torque, RPMs, impact energy, etc.) for handheld tool  120  can be forwarded directly to handheld tool  120 . As a result, operator error in setting the parameters for a handheld tool  120  can be reduced. 
     Communication transceivers  630  comprise one or more wireless radio transceivers coupled with an antenna  640  and configured to operate on any suitable wireless communication protocol including, but not limited to, WiFi, WiMAX, WWAN, implementations of the IEEE 802.11 specification, cellular, two-way radio, satellite-based cellular (e.g., via the Inmarsat or Iridium communication networks), mesh networking, implementations of the IEEE 802.15.4 specification for personal area networks, and implementations of the Bluetooth® standard. Personal area network refer to short-range, and often tow-data rate, wireless communications networks. In accordance with various embodiments, communication transceiver(s)  630  are configured to automatic detection of other components (e.g., communication transceiver(s)  720 ,  820 , and  920  of  FIGS. 7, 8, and 9  respectively) and for automatically establishing wireless communications. It is noted that one communication transceiver  630  can be used to communicate with other devices in the vicinity of positioning infrastructure  140  such as in an ad-hoc personal area network while a second communication transceiver  630  can be used to communicate outside of the vicinity positioning infrastructure  140  (e.g., with information management system  101 ). Also shown in  FIG. 6  is a power source  650  for providing power to positioning infrastructure  140 . In accordance with various embodiments, positioning infrastructure  140  can receive power via an electrical cord, or when implemented as a mobile device by battery. 
     Example Reporting Source 
       FIG. 7  is a block diagram of an example reporting source  110  in accordance with one embodiment. In the embodiment of  FIG. 7 , reporting source  110  comprises a data receiver  710 , a communication transceiver(s)  720 , an antenna  730 , and a power source  740 . For the purposes of brevity, the discussion of computer system  102  in  FIG. 2  is understood to describe components of data receiver  710  as welt Data receiver  710  is configured to receive task data  131  generated by, for example, operator device  510  and building site device  530  which describe events, conditions, operations, and objects present at a construction site. Data receiver  710  is also configured to convey this task data  131  in the form of an asset report  111  to information management system  101 . It is noted that asset report  111  may comprise an abbreviated version of the task data  131 , or may comprise additional data in addition to task data  131 . In one embodiment, asset report  111  comprises a compilation of multiple instances of task data collected over time from a single operator device  510 , or building site device  530 . In another embodiment, asset report  111  comprises a compilation of multiple instances of task data  131  generated by a plurality of operator devices  510 , or building site devices  530 . In accordance with various embodiments, reporting source  110  can generate asset report  111  periodically when a pre-determined time interval has elapsed, as a result of a request or polling from information management system  101 , or as a result of receiving task data  131  from an operator device  510  or building site device  530 . It is noted that a user of operator device  510  or building site device  530  can also initiate generating asset report  111 . 
     Reporting source  110  further comprises communication transceiver(s)  720  which are coupled with antenna  730  and a power source  740 . Again, for the purposes of brevity, the discussion of communication transceiver(s)  630 , antenna  640 , and power source  650  of  FIG. 6  is understood to describe communication transceiver(s)  720 , antenna  730 , and power source  740 , respectively, of reporting source  110  as well. 
     Example Tool Position Detector 
       FIG. 8  is a block diagram of an example tool position detector  121  in accordance with one embodiment. In  FIG. 8 , tool position detector  121  comprises an optional position determination module  810 , communication transceiver(s)  820 , antenna  830 , and orientation sensors  840 . In accordance with various embodiments, tool position detector  121  is configured to detect and report the orientation, and optionally, the position of handheld tool  120 . It is noted that in accordance with various embodiments, the position of handheld toot  120  can be determined by building site device  530  rather than a device co-located with handheld tool  120 . In one embodiment, position determination module  810  comprises a GNSS receiver (e.g., GNSS receiver  1000  of  FIG. 10 ), or another system capable of determining the position of handheld tool  120  with a sufficient degree of precision. It is noted hat the position of, for example, antenna  1032  of  FIG. 10 , cat be offset by a user interface  130  coupled with handheld device to more precisely reflect the working end of handheld tool  120 . For example, if handheld tool  120  is coupled with a drill bit, user interface  130  of operator device  510  can apply an offset (e.g., 3 centimeters lower and 100 centimeters forward of the position of antenna  1032 ). In another embodiment, position determination module  810  utilizes a camera which captures images of structures and implements photogrammetric processing techniques to these images to determine the position of handheld tool  120 . In at least one embodiment, the captured image can be sent to another component of information management network  100  (e.g., to information management system  101 , or to positioning infrastructure  140 ) to perform the photogrammetric processing of the image captured by position determination module  810 . In one embodiment, operator device  510  can use sensors  550  can automatically provide information which identifies a consumable coupled with which handheld tool  120  is coupled. Operator device  510  can then identify characteristics of that consumable so that the working end of handheld tool  120 , when coupled with that consumable, can be known. Alternatively, information identifying a consumable can be manually entered by an operator of handheld tool  120  via user interface  130 . 
     Again, for the purposes of brevity, the discussion of communication transceiver(s)  630  and antenna  640  of  FIG. 6  is understood to describe communication transceiver(s)  820  and antenna  830  respectively of reporting source tool position detector  121  as well. Orientation sensor(s)  840  are configured to determine the orientation of handheld tool  120  in both an X Y plane, as well as tilt of handheld tool  120  around an axis. lit accordance with various embodiments, orientation sensors comprise, but are not limited to, azimuth determination devices such as electronic compasses, as well inclinometers (e.g., operable for determination of tilt in 3 axes), gyroscopes, accelerometers, depth cameras, multiple GNSS receivers or antennas, magnetometers, distance measuring devices, etc., which can determine whether handheld tool  120  is correctly aligned along a particular axis to perform a task. This facilitates correctly orienting/aligning handheld tool  120  above a designated position in order perform a task. Using a drill as an example, once the end of the drill bit coupled with handheld tool  120  has been positioned above the location where the hole is to be drilled (e.g., using cues provided by position determination module  810  and/or a GNSS receiver  1000  disposed within positioning infrastructure  140  of operator device  510  and/or building site device  530 ) orientation sensors  840  are used to determine whether handheld tool  120  is property aligned to drill the hole as desired. It is noted that in one embodiment, a series of communications between operator device  510  and building site device  530  may be exchanged in the process of correctly orienting/aligning handheld tool  120 . In one embodiment, tool position detector  121  communicates with a user interface  130  of operator device  510  to provide cues to guide the operator of handheld tool  120  in correctly aligning handheld tool  120  along the correct axis. As the operator changes the axis of handheld tool  120  in response to visual cues displayed on user interface  130 , orientation sensors  840  will determine the orientation/alignment of handheld tool  120 . When it is determined that handheld tool  1120  is aligned within pre-determined parameters, an indication is displayed and/or annunciated to the operator of handheld tool  120  via user interface  130 . 
     Example User Interface 
       FIG. 9  is a block diagram of an example user interface  1130  in accordance with one embodiment. In  FIG. 9 , user interface  130  comprises a data receiver  910 , communication transceiver(s)  920  coupled with antenna  930 , and a power source. For the purposes of brevity, the discussion of computer system  102  in  FIG. 2  is understood to describe components of data receiver  910  as well. Also, for the purposes of brevity, the discussion of communication transceiver(s)  630 , antenna  640 , and power source  650  of  FIG. 6  is understood to describe communication transceiver(s)  920 , antenna  930 , and power source  940  respectively of user interface  130  as well. The user interface  130  is capable of communicating with tool position detector  121 , is operable for receiving data, displaying data to an operator of handheld tool  120 , detecting and/or selecting materials, assets, consumables, and personnel, reporting operating parameters of handheld tool  120 , and reporting task data describing the performance of a task. In one embodiment, user interface  130  is coupled with, or is integral to, handheld tool  120 . In another embodiment, user interface  130  can be disposed in a separate device (e.g., operator device  510  or building site device  530 ). As discussed above, in one embodiment user interface  130  comprises a user wearable display such as a set of heads-up display glasses. 
     Example GNSS Receiver 
       FIG. 10 , shows an example GNSS receiver  1000  in accordance with one embodiment. It is appreciated that different types or variations of GNSS receivers may also be suitable for use in the embodiments described herein. In  FIG. 10 , received L 1  and L 2  signals are generated by at least one GPS satellite. Each GPS satellite generates different signal L 1  and L 2  signals and they are processed by different digital channel processors  1052  which operate in the same way as one another.  FIG. 10  shows GPS signals (L1=1575.42 MHz, L2=1227.60 MHz) entering GNSS receiver  1000  through a dual frequency antenna  1032 . Antenna  1032  may be a magnetically mountable model commercially available from Trimble Navigation of Sunnyvale, Calif. Master oscillator  1048  provides the reference oscillator which drives all other clocks in the system. Frequency synthesizer  1038  takes the output of master oscillator  1048  and generates important clock and local oscillator frequencies used throughout the system. For example, in one embodiment frequency synthesizer  1038  generates several timing signals such as a 1st (local oscillator) signal LO 1  at 1400 MHz, a 2nd local oscillator signal LO 2  at 175 MHz, an SCLK (sampling clock) signal at 25 MHz, and a MSEC (millisecond) signal used by the system as a measurement of local reference time. 
     A filter/LNA (Low Noise Amplifier)  1034  performs filtering and low noise amplification of both L 1  and L 2  signals. The noise figure of GNSS receiver  1000  is dictated by the performance of the filter/LNA combination. The downconvertor  1036  mixes both L 1  and L 2  signals in frequency down to approximately 175 MHz and outputs the analogue L 1  and L 2  signals into an IF (intermediate frequency) processor  1050 . IF processor  1050  takes the analog L 1  and L 2  signals at approximately 175 MHz and converts them into digitally sampled L 1  and L 2  inphase (L 1  I and L 2  I) and quadrature signals (L 1  Q and L 2  Q) at carrier frequencies 420 KHz for L 1  and at 2.6 MHz for L 2  signals respectively. At least one digital channel processor  1052  inputs the digitally sampled L 1  and L 2  inphase and quadrature signals. All digital channel processors  1052  are typically are identical by design and typically operate on identical input samples. Each digital channel processor  1052  is designed to digitally track the L 1  and L 2  signals produced by one satellite by tracking code and carrier signals and to from code and carrier phase measurements in conjunction with the microprocessor system  1054 . One digital channel processor  1052  is capable of tracking one satellite in both L 1  and L 2  channels. Microprocessor system  1054  is a general purpose computing device which facilitates tracking and measurements processes, providing pseudorange and carrier phase measurements for a navigation processor  1058 . In one embodiment, microprocessor system  1054  provides signals to control the operation of one or more digital channel processors  1052 . Navigation processor  1058  performs the higher level function of combining measurements in such a way as to produce position, velocity and time information for the differential and surveying functions. Storage  1060  is coupled with navigation processor  1058  and microprocessor system  1054 . It is appreciated that storage  1060  may comprise a volatile or non-volatile storage such as a RAM or ROM, or some other computer-readable memory device or media. In one rover receiver embodiment, navigation processor  1058  performs one or more of the methods of position correction. 
     In some embodiments, microprocessor  1054  and/or navigation processor  1058  receive additional inputs for use in refining position information determined by GNSS receiver  1000 . In some embodiments, for example, corrections information is received and utilized. Such corrections information can include differential GPS corrections, RTK corrections, and wide area augmentation system (WAAS) corrections. 
     Automated Hand Tool Task Verification 
     While it is important to record information such as the parameters of a hole which has been drilled, it is also important to collect and record data regarding the application or installation of components and materials. As an example, it is important to know the specifications of fastening elements, such as anchors. which are used to ensure that the correct anchor is being installed. It is also important to know the installation parameters such as the depth a mechanical fastener was installed, the torque or force applied when installing a mechanical fastener, the amount and type of adhesive applied, etc. As described above, embodiments of the present technology permit automatically verifying tools, materials, and other assets which are used when performing tasks at a site. Thus, using operator device  510 , an operator can verify that the correct fastener or material is being used for a task. The operator can similarly verify that the correct drivers for installing the fastener for performing a particular task are installed in handheld tool  120  before and/or during performance of the task. Similarly, the operator can similarly verify that the correct replaceable working end (e.g., bit, blade, chisel, driver, or the like) for performing a particular task are installed in handheld tool  120  before and/or during performance of the task. The operator can also receive operating parameters for handheld toot  120  for a task. As described above, the operating parameter can be automatically implemented by handheld tool  120  and can be verified both by the operator of handheld tool  120  and by information management system  101 . During the actual performance of the task, handheld tool  120  can monitor whether the operating parameters are being met, or whether a generating a warning or cessation of operations is appropriate. Thus, handheld tool  120  is capable of determining whether a task has been performed in accordance with the designated operating parameters and can generate a message which indicates whether the task has been completed in accordance with the designated parameters, or whether the parameters have not been met and the task should be repeated. Again, all of this information is conveyed via information management network  100  and can be done in a manner which is transparent to the operator of handheld tool  120 . Furthermore, this information can be used to update in real-time the blueprints  105  so that they reflect an as-built configuration of a building. Also, this information can be used in quality assurance and building inspection situations to verify, for example, that the correct fastener was installed in a correctly drilled hole and that the correct amount of force was applied when the fastener was installed. In one embodiment, handheld tool  120  can capture the operating parameters of a task it is performing and either convey those parameters to information management system  101  via asset report  111 , or generate an updated record which is conveyed to information management system  101 . 
       FIG. 11  is a flowchart of a method  1100  for automated handheld tool task verification, in accordance with at least one embodiment. The flow chart of method  1100  includes some procedures that, in various embodiments, are carried out by one or more processors under the control of computer-readable and computer-executable instructions. In this fashion, procedures described herein and in conjunction with the flow chart of method  1100  are, or may be, implemented in an at mated fashion using a computer, in various embodiments. The computer-readable and computer-executable instructions can reside in any tangible, non-transitory computer-readable storage media, such as, for example, in data storage features such as peripheral computer-readable storage media  202 , RAM  208 , ROM  210 , and/or storage device  212  (all of  FIG. 2 ) or the like. The computer-readable and computer-executable instructions, which reside on tangible, non-transitory computer-readable storage media, are used to control or operate in conjunction with, for example, one or some combination of processor(s)  206  (see  FIG. 2 ), or other similar processor(s). Although specific procedures are disclosed in the flow chart of method  1100 , such procedures are examples. That is, embodiments are well suited to performing various other procedures or variations of the procedures recited in the flow chart of method  1100 . Likewise, in some embodiments, the procedures in the flow chart of method  1100  may be performed in an order different than presented and/or not all of the procedures described may be performed. It is further appreciated that procedures described in the flow chart of method  1100  may be implemented in hardware, or a combination of hardware with firmware and/or software, 
     In operation  1110 , at least one operating parameter for performing a task is received at a handheld tool. For example, the handheld tool may verify that the type of working end was installed in the tool during performance of the task, the force applied to the work end, the length of time taken to perform the task and/or other information that can be measured and recorded by the tool regarding the operation or use of the tool in performance of the task. In various embodiments, information management system  101  is used to access information describing a task. For example, the task may be setting a fastener with the handheld tool. Among the data which can be stored at information management system  101  are plans (e.g., blueprints  105 , CAD drawings, etc.), schedules, lists of tasks and materials, and the like which are used during the construction process. As described above, this data can be updated in real-time and changed to reflect the current as-built configuration of a project. As a result, schedules and tasks can also be updated in real-time to prevent scheduling conflicts, prevent damage to finished structures and tasks, and to change the order of tasks based upon the current as-built configuration of the project. In accordance with various embodiments, some, or all, of the tasks performed to complete a project may have prescribed standards or parameters for performing the task. As an example, a mechanical fastener may have to be tightened to a specified minimum torque in order to comply with building codes. In accordance with various embodiments, these standards can be stored at information management system  101  and accessed when an operator is ready to perform a specific task, the operator can send a message to information management system  101 . In response, information management system  101  can look up the task and, if there are parameters for performing the task specified, send these parameters to the operator&#39;s handheld tool  120  via positioning infrastructure  140 . 
     In operation  1120  of  FIG. 11 , it is verified at the handheld tool that it is configured with the at least one operating parameter. For example, the handheld tool  120  may verify that it has the correct bit, blade, driver, or other working end installed. This may also involve the handheld tool disabling operation if not configured properly based on received operating parameters for a task. In accordance with various embodiments, some, or all, of the tasks performed to complete a project may have prescribed standards or parameters for performing the task. As an example, a mechanical fastener may have to be tightened to a specified minimum torque in order to comply with building codes. In accordance with various embodiments, these standards can be stored at information management system  101  and accessed when an operator is ready to perform a specific task, the operator can send a message to information management system  101 . In response, information management system  101  can look up the task and, if there are parameters for performing the task specified, send these parameters to the operator&#39;s handheld tool  120  via positioning infrastructure  140 . 
     In operation  1130  of  FIG. 11 , data is generated by the handheld tool that the task was performed in accordance with the at least one operating parameter. For example, the handheld tool  120  may verify that the type of working end was installed in the tool during performance of the task, the force applied to the work end, the length of time taken to perform the task and/or other information that can be measured and recorded by the tool regarding the operation or use of the tool in performance of the task. In at least one embodiment, handheld tool  120  can generate data which indicates its operating parameters. This data can be sent from handheld tool  120  prior to beginning the task, or after the task has been completed to verify the operating parameters of handheld tool  120  while the task was performed. 
     For example, as descried above, a camera coupled with handheld tool  120  can capture an image, images, or video showing the work before, during, and after it is performed. The captured media can verify that the hole was cleanly drilled, did not damage surrounding structures, and that excess material was removed. Similarly, as was discussed above, various sensors associated with the handheld tool can be used to capture and send task data  131  associated with the task performed. This task data provides metrics for determining how well various operations associated with the task have been performed. With respect to setting a fastener, some metrics collected can include, in some embodiments, time taken to drill a hole and/or depth to which hole is drilled. images and/or video may be captured of the task at various times by the handheld tool. For example, in some embodiments, one or more of the following images and/or videos may be captured and recorded: an image of the area to be worked before initiation of the task; an video of the hole being drilled; an image of the drilled hole; an video of the drilled hole being cleaned; an image of the cleaned hole; a video of adhesive being applied in the hole; an image of adhesive applied in the hole; a video of the fastener being set in the hole; and an image of the fastener set in the hole. Although this method has been described with respect to verification of the setting of a fastener, it can be applied to verification of completion of other tasks performed using handheld tools. 
     Embodiments of the present technology are thus described. While the present technology has been described in particular embodiments, it should be appreciated that the present technology should not be construed as limited to these embodiments alone, but rather construed according to the following claims.
