Summary of the Invention

Problems to be Solved by the Invention

[0005] For example, in an information processing system that uses a video captured by a wearable terminal carried by an on-site worker for on-site work support or securing on-site work evidence, in addition to the time period when the on-site worker is working around the equipment of the work target, there is also a time period when the on-site worker is at a location away from the equipment (for example, from the time when the on-site worker moves from the location where the equipment of the work target is installed to a vehicle to pick up tools). In such a case, the shooting data may continue to be saved or transmitted.

[0006] If the storage or transmission of captured data continues even when the field worker is away from the equipment, the battery consumption of the wearable device will increase compared to when the storage or transmission of captured data is stopped during those times. Furthermore, if the storage or transmission of captured data is stopped during those times, the field worker will have to manually start and stop the storage or transmission of captured data. Similarly, if the recording is stopped during those times, the field worker will have to manually start and stop the recording. Moreover, it has often been difficult to determine, using a uniform rule, whether the field worker is working near the equipment or away from it, and to control the start and stop of recording, the start and stop of saving captured data, or the start and stop of transmitting captured data. Patent Document 1 does not address these issues.

Embodiments for Carrying Out the Invention

[0027] Next, embodiments of the present disclosure will be described in detail.

[0028] [First Embodiment] [System Configuration] FIG. 1 is a configuration diagram of an example of the information processing system 1 according to the present embodiment. The information processing system 1 shown in FIG. 1 includes a wearable terminal 10, an information processing device 20, and an analysis worker terminal 30.

[0029] The wearable device 10 is a device carried or worn by a field worker performing field work at site 2. The wearable device 10 carried or worn by the field worker can record video from the field worker's first-person perspective. The video from the field worker's first-person perspective may be a video taken in the direction the field worker is looking, or a video taken in front of the field worker.

[0030] For example, the wearable device 10 can be attached to any location on the field worker's arm, near their eyes, near their ears, around their neck, or on the clothing they are wearing. The wearable device 10 may be a dedicated device or a smartphone with a dedicated application installed. A dedicated device for the wearable device 10 is, for example, a neck-worn wearable device 10 that is attached to the field worker's neck to record videos from the field worker's first-person perspective. A smartphone with a dedicated application installed may be attached to the field worker using, for example, a smartphone harness or smartphone holder. In this embodiment, a neck-worn wearable device 10 that is attached to the field worker's neck to record videos from the field worker's first-person perspective will be described as an example.

[0031] The wearable device 10 is connected to the information processing device 20 via a network 50 in a communicative manner. The wearable device 10 may also be connected to the information processing device 20 via the network 50 by utilizing the communication function of a mobile device such as a field worker's smartphone. The network 50 is, for example, the internet. The network 50 may also be a LAN (Local Area Network) or a dedicated communication line.

[0032] The wearable terminal 10 has a control unit 12. The control unit 12 is a hardware configuration that executes programs, and can be a CPU (Central Processing Unit), an ASIC (Application Specific Integrated Circuit), or an FPGA (Field Programmable Gate Array). The wearable terminal 10 can perform various processes described later by having the CPU of the control unit 12 execute a program.

[0033] The information processing device 20 is connected to the wearable terminal 10 and the analysis worker terminal 30 via the network 50 in a communicative manner. The information processing device 20 receives video or still image data (captured data) captured by the wearable terminal 10. The information processing device 20 stores the captured data received from the wearable terminal 10. The information processing device 20 may use the stored captured data for processing, for example, annotation work or remote support work.

[0034] Furthermore, the information processing device 20 has a control unit 22. The control unit 22 is a hardware configuration that executes programs, and can be a CPU, ASIC, or FPGA. For example, the information processing device 20 can perform various processes described later by having a CPU, which is one example of a control unit 22, execute a program.

[0035] The analysis operator terminal 30 is a device used by analysis operators, such as annotators or remote support personnel, to operate the image data stored by the information processing device 20. The analysis operator terminal 30 is equipped with various tools used by analysis operators, such as annotation tools or remote support tools.

[0036] The analysis operator operates the analysis operator terminal 30 to perform annotation work or remote support. The analysis operator terminal 30 receives requests from the analysis operator and transmits the requests to the information processing device 20. The analysis operator terminal 30 receives the response to the request from the information processing device 20 and displays the response.

[0037] The analysis operator terminal 30 is a hardware configuration that executes programs and has a control unit such as a CPU, ASIC, or FPGA. The analysis operator terminal 30 can perform various processes described later by having the CPU, which is an example of a control unit, execute a program.

[0038] The information processing device 20 is, for example, a PC (Personal Computer) or a workstation. The information processing device 20 may also be implemented using an ASP (Application Service Provider) or cloud computing. The analysis worker terminal 30 is a PC, smartphone, tablet, etc.

[0039] The configuration of Information Processing System 1 in Figure 1 is just one example. For example, the Information Processing Device 20 may consist of one or more units. Needless to say, there are various system configurations for Information Processing System 1 depending on the application and purpose.

[0040] <Device configuration> The information processing device 20 in Figure 1 can be implemented, for example, by a computer 500 with the hardware configuration shown in Figure 2. The analysis operator terminal 30 in Figure 1 may also be implemented by a computer 500 with the hardware configuration shown in Figure 2.

[0041] Figure 2 is a hardware configuration diagram of an example of a computer 500 according to this embodiment. The computer 500 includes an input device 501, a display device 502, an external interface 503, RAM (Random Access Memory) 504, ROM (Read Only Memory) 505, a CPU 506, a communication interface 507, and an HDD (Hard Disk Drive) 508, and these are all interconnected via bus B. The input device 501 and the display device 502 may be connected and used only when necessary.

[0042] The input device 501 is a touch panel, operation keys, buttons, keyboard, or mouse used for operation. The display device 502 consists of a display that shows the screen and a speaker that outputs sound.

[0043] Communication I / F 507 is an interface for computer 500 to communicate data via network 50. HDD 508 is an example of a non-volatile storage device that stores programs and data. Programs and data include the OS (Operating System), which is the basic software that controls the entire computer 500, and applications that provide various functions on the OS. Computer 500 may use an SSD (Solid State Drive) instead of HDD 508.

[0044] External I / F 503 is an interface to external devices. External devices include recording media 503a. Computer 500 reads from and writes to recording media 503a via external I / F 503.

[0045] Recording media 503a include flexible disks, CDs (Compact Discs), DVDs (Digital Versatile Discs), SD (Secure Digital) memory cards, USB (Universal Serial Bus) memory, etc.

[0046] ROM505 is an example of non-volatile semiconductor memory (storage device) that can retain programs and data even when the power is turned off. ROM505 stores programs and data such as the BIOS (Basic Input Output System), OS settings, and network settings that are executed when the computer 500 starts up. RAM504 is an example of volatile semiconductor memory (storage device) that temporarily holds programs and data.

[0047] The CPU 506 is a arithmetic unit that controls and implements the functions of the entire computer 500 by reading programs and data from a storage device such as the ROM 505 or HDD 508 onto the RAM 504 and executing processing. The CPU 506 is an example of the control unit 22 and the analysis control unit of the information processing device 20.

[0048] The wearable terminal 10 in Figure 1, for example, a neck-worn type wearable terminal 10, is realized by the hardware configuration shown in Figures 3 and 4. Figure 3 is an external view of an example of the wearable terminal 10 according to this embodiment. Figure 4 is a functional configuration diagram of an example of the wearable terminal 10 according to this embodiment.

[0049] The housing of the wearable device 10 comprises a left arm section 110, a right arm section 120, and a main body section 130. The left arm section 110 and the right arm section 120 extend forward from the left and right ends of the main body section 130, respectively. When viewed from above, the wearable device 10 has a structure that forms a roughly U shape as a whole. For example, when a field worker, who is one example of a wearer, puts on the wearable device 10, they place the main body section 130 in contact with the back of their neck and hook the left arm section 110 and the right arm section 120 around their neck, letting them hang down from the sides of their neck towards their chest.

[0050] The left arm 110 and the right arm 120 are each provided with multiple sound-collecting units 141 to 145. The sound-collecting units 141 to 145 are, for example, microphones. The sound-collecting units 141 to 145 are primarily positioned to acquire the voices of the wearer and the person they are speaking with. Sound-collecting units 141 and 142 are provided on the left arm 110. Sound-collecting units 143 and 144 are provided on the right arm 120. The left arm 110 and the right arm 120 may be provided with one or more additional sound-collecting units.

[0051] In the example shown in Figure 3, in addition to sound collection units 141 and 142, a sound collection unit 145 is provided on the left arm 110. The sound signals acquired by sound collection units 141 to 145 are transmitted to a control unit 12 located within the main body 130, where predetermined processing is performed. For example, the sound signals acquired by sound collection units 141 to 145 are used to control the imaging unit 160 by voice recognition, such as starting and stopping shooting, starting and ending the saving of shooting data, starting and ending the transmission of shooting data.

[0052] The left arm portion 110 is further equipped with an imaging unit 160. The imaging unit 160 is located on the tip surface 112 of the left arm portion 110. The imaging unit 160 captures video and still images of the front view of the field worker. The captured data from the imaging unit 160 is transmitted to the control unit 12 in the main body portion 130. The captured data from the imaging unit 160 is stored, for example, in the storage unit 181. Alternatively, the wearable terminal 10 may transmit the captured data from the imaging unit 160 to, for example, an information processing device 20 for storage.

[0053] The right arm 120 is further equipped with a non-contact sensor unit 170. The sensor unit 170 is positioned on the tip surface 122 of the right arm 120 to detect, for example, the hand movements of a field worker. The detection information from the sensor unit 170 is used to control the imaging unit 160, such as starting and stopping shooting, starting and ending the saving of shooting data, starting and ending the transmission of shooting data.

[0054] For example, the sensor unit 170 may control the imaging unit 160 when it detects when a field worker's hand or the like approaches, or it may control the imaging unit 160 when it detects a predetermined gesture made by a field worker within the detection range of the sensor unit 170. In this embodiment, the imaging unit 160 is positioned on the tip surface 112 of the left arm unit 110 and the sensor unit 170 is positioned on the tip surface 122 of the right arm unit 120, but the positions of the imaging unit 160 and the sensor unit 170 may be swapped.

[0055] Furthermore, the wearable terminal 10 may use the detection information from the sensor unit 170 to activate at least one of the imaging unit 160, sound collection units 141-145, and control unit 12. The wearable terminal 10 may, for example, activate the imaging unit 160 when the sensor unit 170 detects a specific gesture, while the sensor unit 170, sound collection units 141-145, and control unit 12 are always running and the imaging unit 160 is stopped. Alternatively, the wearable terminal 10 may, for example, activate the imaging unit 160 when the sound collection units 141-145 detect a specific sound, while the sensor unit 170, sound collection units 141-145, and control unit 12 are always running and the imaging unit 160 is stopped.

[0056] As shown in Figure 4, the left arm 110 is equipped with a sound collection unit 141, a sound collection unit 142, a sound collection unit 145, an operation unit 150, and an imaging unit 160. The right arm 120 is equipped with a sound collection unit 143, a sound collection unit 144, and a sensor unit 170. The main body 130 is equipped with a control unit 12, a memory unit 181, a communication unit 182, a proximity sensor 183, a notification unit 184, a gyro sensor 185, an acceleration sensor 186, and a battery 190. In addition to the functional configuration shown in Figure 4, the wearable terminal 10 may be equipped with sensors such as a geomagnetic sensor or a GPS sensor as appropriate.

[0057] The sound collection units 141-145 can utilize known microphones such as dynamic microphones, condenser microphones, and MEMS (Micro-Electrical-Mechanical Systems) microphones. The sound collection units 141-145 convert sound into electrical signals, and the electrical signals are converted into digital information by an A / D conversion circuit and transmitted to the control unit 12.

[0058] The operation unit 150 receives input from field workers. The operation unit 150 can employ, for example, a known switch circuit or a touch panel. The operation unit 150 receives from field workers operations such as instructing the power to be turned ON or OFF, and operations necessary to realize the functions of the wearable terminal 10. The operation unit 150 may also receive from field workers operations to control the imaging unit 160, such as starting shooting, stopping shooting, starting saving of shooting data, ending saving of shooting data, starting transmission of shooting data, and ending transmission of shooting data. Information input via the operation unit 150 is transmitted to the control unit 12.

[0059] The imaging unit 160 captures video or still images. The imaging unit 160 may be, for example, a general-purpose digital camera. The captured data from the imaging unit 160 is transmitted to the control unit 12. The captured data from the imaging unit 160 may be stored in the storage unit 181. Alternatively, the captured data from the imaging unit 160 may be transmitted to the information processing device 20 and stored in the information processing device 20.

[0060] In this embodiment, the start of imaging by the imaging unit 160 does not necessarily mean the start of storing the captured image data in the storage unit 181 or the start of transmission to the information processing device 20. The timing for starting to store the captured image data in the storage unit 181 or the timing for starting to transmit it to the information processing device 20 is managed separately from the timing for starting imaging by the imaging unit 160.

[0061] The sensor unit 170 is a non-contact detection device for detecting the movement of a field worker's fingers or other body parts. The sensor unit 170 is, for example, a proximity sensor or a gesture sensor. The proximity sensor, for example, detects when a field worker's fingers come within a predetermined range. Known types of proximity sensors such as optical, ultrasonic, magnetic, capacitive, or thermal sensors can be used.

[0062] The gesture sensor detects, for example, the movements and shapes of a field worker's fingers. The gesture sensor is, for example, an optical sensor that emits light from an infrared LED towards an object and detects the changes in reflected light with a photodetector, thereby detecting, for example, the movements and shapes of a field worker's fingers. The detection information from the sensor unit 170 is transmitted to the control unit 12 and used to control the imaging unit 160, such as starting and stopping shooting, starting and ending the saving of captured data, starting and ending the transmission of captured data.

[0063] Since the sensor unit 170 generally consumes little power, it is preferable that it remains running while the wearable terminal 10 is powered on. Alternatively, the sensor unit 170 may be activated when the proximity sensor 183 detects that the wearable terminal 10 is being worn.

[0064] The control unit 12 performs calculations to control the wearable terminal 10. The control unit 12 can utilize a processor such as a CPU. The control unit 12 reads a program stored in the memory unit 181 and executes predetermined calculations according to the program. The control unit 12 also writes the results of the calculations performed according to the program to and reads them from the memory unit 181.

[0065] The storage unit 181 stores information used for calculation processing in the control unit 12, as well as the results of the calculation processing. The storage function of the storage unit 181 can be realized by non-volatile memory such as an HDD or SSD. The storage unit 181 may also have a memory function for writing or reading intermediate results of calculation processing by the control unit 12. The memory function of the storage unit 181 can be realized by volatile memory such as RAM or DRAM.

[0066] The communication unit 182 may employ a communication module for wireless communication using known mobile communication standards such as 3G (W-CDMA), 4G (LTE / LTE-Advanced), or 5G. The communication unit 182 may also employ a communication module for wireless communication using a wireless LAN method such as Wi-Fi (registered trademark). Furthermore, the communication unit 182 may employ a communication module for proximity wireless communication using methods such as Bluetooth (registered trademark) or NFC.

[0067] The proximity sensor 183 is located inside the main unit 130 and detects when the neck of a field worker approaches within a predetermined range. The notification unit 184 notifies the field worker with sound, light, or vibration. The notification unit 184 is, for example, a speaker, an LED, or a vibration motor. The notification unit 184 notifies the field worker with sound from a speaker, light from an LED, or vibration from a vibration motor. The notification unit 184 notifies the field worker of the start of shooting, the end of shooting, the start of saving the shooting data, the end of saving the shooting data, the start of transmitting the shooting data, or the end of transmitting the shooting data. The notification unit 184 may also be a bone conduction speaker that notifies the field worker by vibrating the bones of the field worker.

[0068] The gyro sensor 185 detects the rotation or change in orientation of the wearable device 10 as angular velocity. For example, the gyro sensor 185 predicts the shooting direction of the wearable device 10 from the detected angular velocity. The accelerometer 186 also detects the acceleration of the wearable device 10. For example, the accelerometer 186 predicts the shooting position of the wearable device 10 from the detected acceleration.

[0069] The battery 190 is a rechargeable battery that supplies power to various electronic components included in the wearable device 10. The battery 190 may be a lithium-ion battery, lithium polymer battery, alkaline battery, nickel-cadmium battery, nickel-metal hydride battery, or lead-acid battery.

[0070] <Processing> In this embodiment, a field worker performing on-site work at site 2 carries or wears a wearable terminal 10 to record videos of the on-site work. The videos of the on-site work recorded by the wearable terminal 10 are from the field worker's first-person perspective. In this embodiment, as an example of on-site work performed at site 2, an example of on-site work related to air conditioners in a house is described.

[0071] Figure 5 is a diagram illustrating an example of on-site work related to air conditioning systems performed in a residential building. The floor plan shown in Figure 5 represents a part of the floor plan of a house where on-site work related to air conditioning systems is performed. The indoor unit 1000 of the air conditioner is installed in a room of the house (for example, a bedroom). The outdoor unit 1002 of the air conditioner is installed outside the house. For example, on-site workers may move between the indoor unit 1000 and the outdoor unit 1002 via a traffic flow 1020 while performing on-site work related to the air conditioner.

[0072] The area 1010, indicated by the dotted line, represents the first work area for on-site work on the indoor unit 1000. The area 1012, also indicated by the dotted line, represents the second work area for on-site work on the outdoor unit 1002. The first and second work areas are examples of work areas where it is desired to record first-person perspective video of the on-site worker, captured by the wearable terminal 10.

[0073] The first-person perspective video captured by the wearable device 10 may include footage of the area visible from the worker's movement path 1020, which is undesirable from a privacy standpoint. Furthermore, it is burdensome for the worker to have to operate the wearable device 10 to control the start and end of saving or transmitting the footage each time they move between the indoor unit 1000 and the outdoor unit 1002 via the movement path 1020.

[0074] Therefore, in this embodiment, the wearable terminal 10 receives an operation from the field worker to start saving or transmitting the first set of captured data in the first work area and the second work area. After starting to save or transmit the captured data, the wearable terminal 10 determines the deviation from the shooting position or shooting direction from which the saving or transmission of the captured data was started, and based on the deviation, automatically stops shooting, ends saving the captured data, or ends transmitting the captured data. The wearable terminal 10 may also determine the deviation from the shooting position and shooting direction from which the saving or transmission of the captured data was started, and based on the deviation, automatically stop shooting, end saving the captured data, or end transmitting the captured data.

[0075] Furthermore, in this embodiment, when the camera approaches within a predetermined range from the shooting position where the first shooting data was saved or transmitted, the saving or transmission of subsequent shooting data in the first and second work areas is automatically resumed.

[0076] Furthermore, determining whether or not the photographic data was taken in the first and second work areas using a uniform rule is generally difficult because the installation locations of the indoor unit 1000 and the outdoor unit 1002 differ from house to house.

[0077] Thus, in this embodiment, the deviation from the shooting position or shooting direction at which the saving or transmission of the captured data was started can be determined, and based on the deviation, the shooting can be automatically stopped, the saving of the captured data can be terminated, or the transmission of the captured data can be terminated. Furthermore, in this embodiment, the deviation from the shooting position and shooting direction at which the saving or transmission of the captured data was started can be determined, and based on the deviation, the shooting can be automatically stopped, the saving of the captured data can be terminated, or the transmission of the captured data can be terminated. For this reason, in this embodiment, it is possible to control shooting so that captured data in the first work area and the second work area is saved or transmitted, and captured data in the range visible from the movement path 1020 of the on-site worker is not saved or transmitted.

[0078] In this embodiment, since the shooting control prevents the saving or transmission of shooting data outside the first and second work areas, the battery consumption of the wearable terminal 10 can be reduced compared to continuously saving or transmitting shooting data outside the first and second work areas. For example, a field worker who is in charge of multiple sites 2 in a day can use the wearable terminal 10 according to this embodiment to save or transmit shooting data for a longer period of time than a wearable terminal 10 that continues to save or transmit shooting data outside the first and second work areas. Furthermore, the shooting data in the first and second work areas that is saved or transmitted can be used for field work support or to secure evidence of field work.

[0079] In this embodiment, the following processing is provided to control the shooting so as not to save or transmit the shooting data within the range visible from the movement path 1020 of the on-site worker.

[0080] Figure 6 is a flowchart of an example of the shooting control process according to this embodiment. Figure 7 is an explanatory diagram of an example of the shooting control process according to this embodiment. The wearable terminal 10 in Figure 7 is carried or worn by a field worker.

[0081] In step S10, the control unit 12 of the wearable terminal 10 carried or worn by the field worker receives input from the field worker to start shooting and starts shooting with the imaging unit 160. The input from the field worker to start shooting may be an operation input to the operation unit 150, voice recognition using sound signals acquired by the sound collection units 141-145, or detection of a specific gesture by the sensor unit 170.

[0082] Even though the wearable terminal 10 starts taking images with the imaging unit 160 in step S10, it has not yet started storing the captured data in the storage unit 181 or transmitting it to the information processing device 20. Figure 7(A) shows the wearable terminal 10 in a state where it has started taking images with the imaging unit 160, but has not yet started storing the captured data in the storage unit 181 or transmitting it to the information processing device 20.

[0083] In step S12, the control unit 12 of the wearable terminal 10 determines whether it has received input from the field worker to start saving or transmitting the captured data. The input from the field worker to start saving or transmitting the captured data may be an operation input to the operation unit 150, voice recognition using sound signals acquired by the sound collection units 141-145, or detection of a specific gesture by the sensor unit 170. In step S12, the control unit 12 may consider the timing when the measuring instrument is connected to the wearable terminal 10 via Bluetooth® or the like as the timing when it has received input from the field worker to start saving or transmitting the captured data. When the control unit 12 receives input from the field worker to start saving or transmitting the captured data, it starts storing the captured data in the storage unit 181 or transmitting it to the information processing device 20.

[0084] Figure 7(B) shows a state in which a wearable terminal 10, carried or worn by a field worker, approaches the second work area where on-site work on the outdoor unit 1002 is performed. In the state shown in Figure 7(B), the wearable terminal 10 has not started storing the captured data in the storage unit 181 or transmitting it to the information processing device 20 because it has not received input from the field worker to start saving or transmitting the captured data.

[0085] For example, in the state shown in Figure 7(C), when the control unit 12 of the wearable terminal 10 receives input from a field worker to start saving or transmitting the captured data, it performs the process in step S14. In step S14, the control unit 12 records the shooting position or shooting direction at the start of saving or transmitting the captured data in the storage unit 181. For example, the control unit 12 records the shooting position or shooting direction in the storage unit 181 based on the state shown in Figure 7(C).

[0086] In step S16, the control unit 12 of the wearable terminal 10 predicts the current shooting position or direction based on the shooting position or direction at the start of saving or transmitting the shooting data recorded in the memory unit 181 in step S14. The prediction of the shooting position or direction is performed using the angular velocity detected by the gyro sensor 185 and the acceleration detected by the acceleration sensor 186.

[0087] In step S18, the control unit 12 of the wearable terminal 10 compares the reference shooting position or shooting direction at the start of saving or transmitting the shooting data recorded in the storage unit 181 in step S14 with the current shooting position or shooting direction predicted in step S16, and determines the deviation. The control unit 12 determines the deviation from the reference shooting position or shooting direction at the start of saving or transmitting the shooting data recorded in the storage unit 181 in step S14.

[0088] In step S20, the control unit 12 of the wearable terminal 10 determines whether the deviation determined in step S18 is greater than or equal to a predetermined value. The control unit 12 repeats the processes of steps S16 to S20 until it determines that the deviation determined in step S18 is greater than or equal to a predetermined value.

[0089] Figure 7(D) shows an example where the field worker turns sideways from the state shown in Figure 7(C), but the displacement determined in step S18 is not greater than a predetermined value. In Figure 7(D), since the displacement determined in step S18 is not greater than a predetermined value, it is determined that field work in the second work area is continuing. Therefore, the control unit 12 continues to store the captured data in the storage unit 181 or transmit it to the information processing device 20.

[0090] Furthermore, if the control unit 12 determines that the deviation determined in step S18 is greater than or equal to a predetermined value, it performs the processing in step S22. In step S22, the control unit 12 terminates the saving of the captured data or terminates the transmission of the captured data. In step S22, the control unit 12 may terminate the shooting.

[0091] Figure 7(E) shows an example where, from the state in Figure 7(C), the field worker has moved away from the outdoor unit 1002, facing a direction significantly different from the direction of the outdoor unit 1002, and the deviation determined in step S18 is determined to be greater than a predetermined value. In Figure 7(E), since the deviation determined in step S18 is greater than a predetermined value, it is determined that the field worker has moved away from the second work area. Therefore, the control unit 12 terminates the storage of the captured data in the storage unit 181 or the transmission of the data to the information processing device 20.

[0092] Note that the state in Figure 7(E) is an example, showing a case where the field worker is facing a direction more than a predetermined value away from the direction of the outdoor unit 1002, and the field worker is more than a predetermined value away from the outdoor unit 1002, and in this case, step S18 determines that the deviation is greater than a predetermined value. When determining the deviation by considering both the shooting position and shooting direction at the start of saving or transmitting the captured data, it is possible to stop shooting, end saving the captured data, or end transmitting the captured data with greater accuracy than when determining the deviation by considering only one of the shooting position or shooting direction. Because it is possible to stop shooting, end saving the captured data, or end transmitting the captured data with greater accuracy, the battery consumption of the wearable terminal 10, which is carried or worn by the field worker to take pictures of the field worker's work and save the captured data or transmit it to the information processing device 20, can be reduced.

[0093] For example, when determining the deviation by considering only the shooting position, it was difficult in cases where a field worker working near the outdoor unit 1002, the target of the work, was talking to a customer with their back to the outdoor unit 1002. In such cases, by considering both the shooting position and the shooting direction, it is possible to treat cases where the shooting direction is significantly off as outside the target, and to accurately stop shooting, terminate saving of shooting data, or terminate transmission of shooting data.

[0094] For example, when determining deviations by considering only the shooting direction, it was difficult in cases where a field worker disassembled the outdoor unit 1002, which was the work target, and replaced parts, turned in a direction other than the outdoor unit 1002 to place the disassembled parts in another location. In such cases, by considering both the shooting position and the shooting direction, it is possible to treat objects that are not far from the shooting position as the target, and continue to save or transmit the shooting data with high accuracy.

[0095] For example, when determining deviations by considering only the shooting direction, it was difficult in cases where a field worker disassembling the outdoor unit 1002, which is the work target, and replacing parts, turns in a direction other than the outdoor unit 1002 to retrieve tools, etc. In such cases, by considering both the shooting position and the shooting direction, it is possible to treat objects that are not far from the shooting position as the target, and continue to save or transmit the shooting data with high accuracy.

[0096] The control unit 12 may determine in step S18 that the deviation is greater than a predetermined amount if the field worker is facing a direction more than a predetermined amount away from the direction of the outdoor unit 1002, or if the field worker is more than a predetermined amount away from the outdoor unit 1002.

[0097] The shooting position or direction recorded in step S14 is used to determine whether or not to resume saving or transmitting the shooting data.

[0098] In step S26, the control unit 12 of the wearable terminal 10 controls the notification unit 184 to notify the field worker by sound, light, or vibration that it has finished storing the captured data in the storage unit 181 or transmitting it to the information processing device 20, and proceeds to step S28. If the control unit 12 of the wearable terminal 10 determines in step S12 that it has not received input from the field worker to start saving or transmitting the captured data, it proceeds to step S24. In step S24, the control unit 12 of the wearable terminal 10 determines whether it has received input from the field worker to stop shooting. If the control unit 12 receives input from the field worker to stop shooting, it terminates the process in the flowchart of Figure 6. If the control unit 12 does not receive input from the field worker to stop shooting, it proceeds to step S28.

[0099] In step S28, the control unit 12 of the wearable terminal 10 predicts the current shooting position using the angular velocity detected by the gyro sensor 185 and the acceleration detected by the acceleration sensor 186. If the predicted current shooting position is within a predetermined range from the shooting position recorded in the storage unit 181 in step S14, the control unit 12 proceeds to step S30, resumes storing the shooting data in the storage unit 181 or transmitting it to the information processing device 20, and then returns to the process in step S16.

[0100] A shooting location where the field worker has previously initiated the operation to save or transmit captured data is highly likely to be a work area where the wearable terminal 10 wants to record a first-person perspective video of the field worker. Therefore, when the current shooting location of the wearable terminal 10 approaches a predetermined range from a shooting location where the field worker has previously initiated the operation to save or transmit captured data, the control unit 12 resumes saving or transmitting the captured data in step S30. In step S28, if the predicted current shooting location is not within a predetermined range from the shooting location recorded in the storage unit 181 in step S14, the control unit 12 returns to the process in step S12.

[0101] According to the flowchart in Figure 6, if a field worker initiates the saving or transmission of the first set of captured data in a work area where they want to retain the data captured by the wearable terminal 10, the saving or transmission of subsequent captured data in that work area can be automatically resumed.

[0102] For example, in on-site work related to an air conditioner as shown in Figure 5, the on-site worker moves between a first work area where on-site work on the indoor unit 1000 is performed and a second work area where on-site work on the outdoor unit 1002 is performed. Therefore, by using the wearable terminal 10 according to this embodiment, once the operation to start saving or transmitting captured data is performed in the first work area and the second work area, the saving or transmission of captured data can be automatically terminated when the worker moves away from the first work area and the second work area. Furthermore, by using the wearable terminal 10 according to this embodiment, once the operation to start saving or transmitting captured data is performed in the first work area and the second work area, the saving or transmission of captured data can be automatically resumed when the worker approaches the first work area and the second work area.

[0103] According to the wearable terminal 10 of this embodiment, battery consumption can be reduced by automatically ending the saving or transmission of captured data when moving from the first work area and the second work area. Furthermore, according to the wearable terminal 10 of this embodiment, the storage capacity and communication volume of captured data can be reduced. As a result, the wearable terminal 10 of this embodiment can reduce communication costs. In addition, the wearable terminal 10 of this embodiment can extend the storage life.

[0104] Furthermore, the wearable terminal 10 according to this embodiment is preferable from a privacy standpoint because it can suppress the storage of photographic data within the range visible from the movement path 1020 of the on-site worker.

[0105] Furthermore, according to the wearable terminal 10 of this embodiment, by suppressing the storage of photographic data within the range visible from the movement path 1020 of the field worker, the amount of photographic data stored in the wearable terminal 10 or information processing device 20 is reduced, thereby reducing the workload of the analysis worker.

[0106] The flowchart in Figure 6 illustrates an example where the timing for receiving input from the field worker to initiate shooting is different from the timing for receiving input from the field worker to initiate saving or transmitting the captured data.

[0107] The timing at which the system receives input from a field worker to initiate shooting and the timing at which it receives input from a field worker to initiate saving or transmitting the captured data may coincide. For example, the wearable terminal 10 may start storing the captured data in the storage unit 181 or transmitting it to the information processing device 20 upon receiving input from a field worker to initiate shooting.

[0108] Figure 8 is a flowchart of an example of the shooting control process according to this embodiment. Note that the process in the flowchart of Figure 8 is the same as that in the flowchart of Figure 6, with some exceptions, so explanations will be omitted as appropriate.

[0109] In step S50, the control unit 12 of the wearable terminal 10 carried or worn by the field worker determines whether or not it has received input from the field worker to start shooting. The input from the field worker to start shooting may be an operation input to the operation unit 150, voice recognition using sound signals acquired by the sound collection units 141-145, or detection of a specific gesture by the sensor unit 170. When the control unit 12 receives input from the field worker to start shooting, it starts storing the shooting data in the storage unit 181 or transmitting it to the information processing device 20.

[0110] In step S52, the control unit 12 records the shooting position or shooting direction at the start of shooting in the storage unit 181 as a reference. In step S54, the control unit 12 of the wearable terminal 10 predicts the current shooting position or shooting direction based on the shooting position or shooting direction at the start of shooting recorded in the storage unit 181 in step S52.

[0111] In step S56, the control unit 12 of the wearable terminal 10 compares the reference shooting position or shooting direction at the start of shooting, which was recorded in the memory unit 181 in step S52, with the current shooting position or shooting direction predicted in step S54, and determines the discrepancy.

[0112] In step S58, the control unit 12 of the wearable terminal 10 determines whether the deviation determined in step S56 is greater than or equal to a predetermined value. The control unit 12 repeats the processes of steps S54 to S58 until it determines that the degree of deviation determined in step S58 is greater than or equal to a predetermined value.

[0113] Furthermore, if the control unit 12 determines that the deviation determined in step S58 is greater than or equal to a predetermined value, it performs the process in step S60. In step S60, the control unit 12 stops shooting. By stopping shooting, the control unit 12 terminates the saving of the shooting data or terminates the transmission of the shooting data.

[0114] The shooting position or shooting direction recorded in step S52 is used to determine whether or not to resume shooting.

[0115] In step S64, the control unit 12 of the wearable terminal 10 controls the notification unit 184 to notify the field worker that shooting has ended using sound, light, or vibration, and proceeds to step S66. Also, if the control unit 12 of the wearable terminal 10 determines in step S50 that it has not received input from the field worker to start shooting, it proceeds to step S62. In step S62, the control unit 12 of the wearable terminal 10 determines whether or not it has received input from the field worker to stop shooting. If the control unit 12 receives input from the field worker to stop shooting, it terminates the process of the flowchart in Figure 8. Also, if the control unit 12 does not receive input from the field worker to stop shooting, it proceeds to step S66.

[0116] In step S66, the control unit 12 of the wearable terminal 10 predicts the current shooting position. If the predicted current shooting position is within a predetermined range from the shooting position recorded in the memory unit 181 in step S52, the control unit 12 proceeds to step S68, resumes shooting, and then returns to the process in step S54.

[0117] The shooting location where the field worker has previously initiated recording is likely to be a work area where the wearable terminal 10 wants to record a first-person perspective video of the field worker. Therefore, when the current shooting location of the wearable terminal 10 approaches a predetermined range from a shooting location where the field worker has previously initiated recording, the control unit 12 resumes recording in step S68. Also, in step S66, if the predicted current shooting location is not within a predetermined range from the shooting location recorded in the memory unit 181 in step S52, the control unit 12 returns to the process in step S50.

[0118] According to the flowchart in Figure 8, if a field worker initiates the first shooting in a work area where they want to save the captured data from the wearable device 10, subsequent shooting in that work area can be automatically resumed.

[0119] Furthermore, existing image recognition technology may be used to predict the shooting position or direction in the flowchart of Figure 6 or Figure 8. For example, the wearable terminal 10 can predict its shooting position or direction by recognizing the indoor unit 1000 and outdoor unit 1002, etc., that are visible in the captured data while saving or transmitting the captured data. Alternatively, for example, in the flowchart of Figure 6, the wearable terminal 10 may predict its shooting position or direction by recognizing the indoor unit 1000 and outdoor unit 1002, etc., that are visible in the captured data when saving or transmitting the captured data is resumed.

[0120] Predicting the shooting position or direction using image recognition technology can be used to initiate the saving of shooting data, to terminate the saving of shooting data, to initiate the transmission of shooting data, or to terminate the transmission of shooting data, if shooting continues after the saving or transmission of shooting data has finished. Furthermore, predicting the shooting position or direction using image recognition technology can be used to stop shooting, to terminate the saving of shooting data, or to terminate the transmission of shooting data, if shooting does not continue after the saving or transmission of shooting data has finished.

[0121] Prediction of the shooting position or direction using image recognition technology may be used in conjunction with prediction of the shooting position or direction using the angular velocity detected by the gyro sensor 185 and the acceleration detected by the acceleration sensor 186. Alternatively, prediction of the shooting position or direction using image recognition technology may be used instead of prediction of the shooting position or direction using the angular velocity detected by the gyro sensor 185 and the acceleration detected by the acceleration sensor 186.

[0122] Furthermore, in this embodiment, as shown in Figure 5, we have described an example where there are two work areas where we want to record first-person perspective videos of the field worker captured by the wearable terminal 10. However, it is not limited to two locations; there may be one or three or more locations.

[0123] As described above, the information processing system 1 according to this embodiment can reduce the battery consumption of the wearable terminal 10, which is carried or worn by a field worker to take pictures of the field worker's work and store or transmit the captured data to the information processing device 20.

[0124] [Effect] This embodiment is a wearable terminal 10 having a control unit 12, which is carried by a field worker to take pictures. The control unit 12 determines the deviation from the shooting position or shooting direction at the start of saving or transmitting the captured data, and based on the deviation, stops shooting, terminates saving the captured data, or terminates transmitting the captured data.

[0125] The control unit 12 determines the deviation from the shooting position or shooting direction at the start of storing the captured image data in the storage unit 181 or at the start of transmission to the information processing device 20. The deviation represents the difference between the shooting position or shooting direction at the start of storing the captured image data in the storage unit 181 or at the start of transmission to the information processing device 20 and the current shooting position or shooting direction.

[0126] If the deviation exceeds a predetermined value, the current shooting position or shooting direction is different from the shooting position or shooting direction at the start of storage of the shooting data in the storage unit 181 or at the start of transmission to the information processing device 20. Therefore, if the deviation exceeds a predetermined value, the control unit 12 stops shooting, terminates the storage of the shooting data, or terminates the transmission of the shooting data.

[0127] Thus, according to this embodiment, the battery consumption of the wearable terminal 10, which is carried or worn by a field worker to take pictures of the field worker's work and to store or transmit the captured data to the information processing device 20, can be reduced.

[0128] Furthermore, in this embodiment, the wearable terminal 10 records first-person perspective video while being worn by a field worker.

[0129] According to this embodiment, the wearable terminal 10 can be used to record first-person perspective videos while being worn by a field worker.

[0130] In this embodiment, the control unit 12 also determines the deviation from the shooting position and shooting direction at the start of saving or transmitting the captured data.

[0131] The control unit 12 determines the deviation from the shooting position and shooting direction at the start of storage of the captured image data in the storage unit 181 or at the start of transmission to the information processing device 20. The deviation represents the difference between the shooting position and shooting direction at the start of storage of the captured image data in the storage unit 181 or at the start of transmission to the information processing device 20 and the current shooting position and shooting direction.

[0132] If the deviation exceeds a predetermined value, the current shooting position and direction are different from the shooting position and direction at the start of storage of the shooting data in the storage unit 181 or transmission to the information processing device 20. Therefore, if the deviation exceeds a predetermined value, the control unit 12 stops shooting, terminates the storage of the shooting data, or terminates the transmission of the shooting data.

[0133] Thus, according to this embodiment, the battery consumption of the wearable terminal 10, which is carried or worn by a field worker to take pictures of the field worker's work and to store or transmit the captured data to the information processing device 20, can be reduced.

[0134] Furthermore, in this embodiment, the control unit 12 records the shooting position at the start of saving or transmitting the shooting data in the storage unit 181, and after stopping shooting, ending the saving of shooting data, or ending the transmission of shooting data, if the camera approaches within a predetermined range from the shooting position, it resumes shooting, resumes saving shooting data, or resumes transmitting shooting data.

[0135] According to this embodiment, by recording the shooting position at the start of saving or transmitting the captured data, shooting can be resumed, saving of captured data can be resumed, or transmission of captured data can be resumed when the camera approaches a predetermined range from the recorded shooting position.

[0136] In this embodiment, the control unit 12 records multiple shooting positions in the storage unit 181 at the start of saving or transmitting the shooting data.

[0137] According to this embodiment, by recording multiple shooting positions at the start of saving or transmitting the captured data, the saving or transmission of the captured data can be resumed when the camera approaches within a predetermined range from any of the recorded shooting positions.

[0138] In this embodiment, the control unit 12 starts saving or transmitting the captured data according to the operation of the field worker.

[0139] According to this embodiment, the saving or transmission of captured data can be initiated according to the operation of the field worker.

[0140] Furthermore, in this embodiment, the control unit 12 controls the notification unit 184 to notify the field worker of the start of shooting, the end of shooting, the start of saving the shooting data, the end of saving the shooting data, the start of transmitting the shooting data, or the end of transmitting the shooting data.

[0141] According to this embodiment, the wearable terminal 10 can notify field workers of the start of shooting, the end of shooting, the start of saving the shooting data, the end of saving the shooting data, the start of transmitting the shooting data, or the end of transmitting the shooting data.

[0142] Furthermore, in this embodiment, the control unit 12 continues shooting and, based on the deviation, terminates the saving of the shooting data or terminates the transmission of the shooting data.

[0143] According to this embodiment, while continuing to shoot, the storage of shooting data can be terminated or the transmission of shooting data can be terminated based on the deviation. For example, since the wearable terminal 10 continues shooting even after terminating the storage of shooting data or the transmission of shooting data, the prediction of the shooting position or direction using image recognition technology can be used to start saving the shooting data and start transmitting the shooting data.

[0144] This embodiment is a shooting control method performed by a wearable terminal 10, which has a control unit 12 and is carried by a field worker to perform shooting. The control unit 12 determines the deviation from the shooting position or shooting direction at the start of saving or transmitting the shooting data, and based on the deviation, stops shooting, terminates saving the shooting data, or terminates transmitting the shooting data.

[0145] The control unit 12 determines the deviation from the shooting position or shooting direction at the start of storing the captured image data in the storage unit 181 or at the start of transmission to the information processing device 20. The deviation represents the difference between the shooting position or shooting direction at the start of storing the captured image data in the storage unit 181 or at the start of transmission to the information processing device 20 and the current shooting position or shooting direction.

[0146] If the deviation exceeds a predetermined value, the current shooting position or shooting direction is different from the shooting position or shooting direction at the start of storage of the shooting data in the storage unit 181 or at the start of transmission to the information processing device 20. Therefore, if the deviation exceeds a predetermined value, the control unit 12 stops shooting, terminates the storage of the shooting data, or terminates the transmission of the shooting data.

[0147] Thus, according to this embodiment, the battery consumption of the wearable terminal 10, which is carried or worn by a field worker to take pictures of the field worker's work and to store or transmit the captured data to the information processing device 20, can be reduced.

[0148] As described above, this embodiment can be understood to be capable of various modifications to its form and details without departing from the spirit and scope of the claims. [Explanation of Symbols]
