It will be further understood that the terms “includes” and/or “including”, when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
In describing preferred embodiments illustrated in the drawings, specific terminology is employed for the sake of clarity. However, the disclosure of this patent specification is not intended to be limited to the specific terminology so selected, and it is to be understood that each specific element includes all technical equivalents that have the same function, operate in a similar manner, and achieve a similar result.
Referring to FIGS. 1 to 4, an embodiment of the present invention is described. FIG. 1 is a schematic diagram illustrating a configuration of a consultation system 1 according to the embodiment.
As shown in FIG. 1, the consultation system 1 in this embodiment includes an employee-side communication terminal 10, an employee-side sightline detection device 30, an industrial-physician-side communication terminal 40, and a consultation management system 60. The communication terminal 10 and the sightline detection device 30 are located at a consultation room X where an employee visits for consultation with an industrial physician. The sightline detection device 30 is connected to the communication terminal 10 via a cable for transferring image data including at least an image of an eye of the employee. The communication terminal 40 is located at an industrial physician's room Y where the industrial physician works. The consultation management system 60 is located at a place other than the consultation room X and the industrial physician room Y. It should be noted that the consultation management system 60 can also be located at the industrial physician's room Y.
In this embodiment, general-purpose personal computers (PCs) are used for the communication terminals 10 and 40, and they are connected with each other communicably via a communication network 9 such as the Internet and a local area network (LAN).
It should be noted that any one of the communication terminals 10 and 40 can be a smartphone or a tablet device. Furthermore, at least the communication terminal 10 may be a terminal with a build-in sightline detection device 30, such that the communication terminal 10 may be dedicated to the remote consultation. In this disclosure, the communication terminal 10 may be referred to as a first communication terminal, or a counterpart communication terminal from a viewpoint of the communication terminal 40. The communication terminal 40 may be referred to as a second communication terminal.
In this embodiment, the consultation management system 60 operates as a server computer. It should be noted that the consultation management system 60 is implemented by one server computer or multiple server computers.
While in FIG. 1, the consultation system 1 is used by the employee as an example of the first user, and the industrial physician as an example of the second user. The other example combinations of the first user and the second user include a corporate manager as the first user and the industrial physician as the second user, or the employee or the corporate manager as the first user and any other physician, a nurse, or a pharmacist as the second user. The other example combinations of the first user and the second user further include a teacher or an instructor as the first user and a student of any age or a guardian of the student as the second user. Furthermore, the other example combinations of the first user and the second user include a subordinate as the first user and a boss as the second user.
In FIG. 1, the consultation management system 60 transfers data of a medical checkup data screen to the communication terminals 10 and 40, respectively, and the communication terminals 10 and 40 each display the medical checkup data screen. In addition, the sightline detection device 30 transfers image data acquired by capturing at least the employee's eye part to the communication terminal 10, and the communication terminal 10 transfers the image data to the consultation management system 60. After receiving the image data, the consultation management system 60 transfers screen data including an observing point marker v, which is added to reflect the sightline direction of the employee based on the image data to the communication terminal 40. In this case, an eyeball-shaped marker is displayed as an example of the observing point marker v. As a result, even in case of having a remote consultation with the employee, the industrial physician can perceive, from the unstable sightline, that the employee has some concerns or seems to be depressed, just like the face-to-face consultation.
It should be noted that the observing point marker v indicating the employee's sightline direction is not displayed on the communication terminal 10. This is because the industrial physician cannot determine whether or not the employee is in a depression etc. precisely if the employee recognizes his/her own observing point marker v. In addition, the observing point marker v is an example of observing point information. Other examples of the observing point information include not displaying the marker but modifying color of texts or width of frames etc. displayed as the medical checkup data.
Next, an outline of a sightline detection method is described below. FIG. 2 is a schematic diagram illustrating operation of detecting a sightline of the employee in this embodiment. The sightline detection method detects movements of the user's eyeballs to determine directions at which the user is looking. To start detecting movements of the user's eyeballs, firstly, a static part (reference point) and a movable part (moving point) of the user's eyes are detected at the detection device. After detecting the reference point and the moving point, the detection device detects the sightline of the user based on a position of the moving point in accordance with the reference point. There are various sightline detection methods, each of which differs in how the reference point and the moving point are each chosen. Among them, as a typical method, a sightline detection method in which corneal reflex is regarded as the reference point and the pupil is regarded as the moving point to analyze their positional relationship is described below.
In general, the detection device has an infrared light emitting diode (LED) lighting device 301a, which illuminates the user's face, and determines a position of reflected light of the emitted light on the cornea (the corneal reflex) as the reference point. The detection device further has an infrared camera 302a, which detects the user's sightline based on the position of the pupil with reference to the position of the corneal reflex. For example, as shown in FIG. 2, if the pupil of the left eye is located at upper left compared to the position of the corneal reflex, it is detected that the user is looking at upper left. By contrast, if the pupil of the left eye is located at upper right compared to the position of the corneal reflex, it is detected that the user is looking at upper right. The detection device may alternatively use visible ray instead of infrared ray.
In this embodiment, the sightline detection method described above is applied to detect the first user's sightline during remote consultation, which is performed by the terminal 10 at the employee side in cooperation with the terminal 40 at the industrial physician side. As a result, in this embodiment, a screen shown in FIG. 3 is displayed on the communication terminal 10 on the employee side, and a screen shown in FIG. 4 is displayed on the communication terminal 40 on the industrial physician side.
FIG. 3 is a diagram illustrating an employee-side screen in this embodiment. FIG. 4 is a diagram illustrating an industrial-physician-side screen in this embodiment. As shown in FIG. 3, the communication terminal 10 displays a medical checkup data screen 1000 on a display 217 (described later). On the medical checkup data screen 1000, a user's personal information display area 1010, a checkup result display area 1020, a medical history display area 1030, and a lifestyle habit display area 1040 are displayed. On the personal information display area 1010, the user's personal data such as employee name etc. is displayed. The medical checkup management data such as checkup results of the user's medical checkup etc. is displayed on the checkup result display area 1020, the medical history display area 1030, and the lifestyle habit display area 1040. That is, the user personal data and the medical checkup management data, which may be collectively referred to as the medical checkup data, is displayed as the content of the medical checkup data screen 1000. In this embodiment, the remote consultation is used for medical use. However, the purpose of the remote consultation is not limited to that. That is, it is possible to use the remote consultation for business use. As a result, the medical checkup data in this embodiment is an example of the user related data that indicates content related to the user. Other examples of the user related data are a performance result in an example case of a manager as the second user and a staff as the first user, a grade report or an examination sheet in an example case of a teacher as the second user and a student as the first user, an evidential photo or a questioning sheet in an example case of a detective as the second user and a suspect as the first user, and a fortune-telling result or an image of a palm in an example case of a fortune-teller as the second user and a customer as the first user.
By contrast, the communication terminal 40 displays a medical checkup data screen 4000 on a display 217 (described later). On the medical checkup data screen 4000, just like the screen of FIG. 3, a user's personal information display area 4010, a checkup result display area 4020, a medical history display area 4030, and a lifestyle habit display area 4040 are displayed. The user's personal information display area 4010, the checkup result display area 4020, the medical history display area 4030, and the lifestyle habit display area 4040 respectively display the same content as the corresponding user's personal information display area 1010, checkup result display area 1020, medical history display area 1030, and lifestyle habit display area 1040. The medical checkup data screen 4000 additionally displays an observing point marker v, a reception status display area 4110, and an observing point marker display button 4210. On the reception status display area 4110, a message indicating that the communication terminal 40 is receiving image data from the communication counterpart (i.e., the employee) is displayed. In this case, the message “receiving user's image data” is displayed as an example of the message. The observing point marker display button 4210 is a key pressed by the industrial physician to display the observing point marker v on the display 217 at the communication terminal 40. That is, the observing point marker display button 4210 accepts a command to display the observing point marker v from the industrial physician. It should be noted that the displayed position of the observing point marker v on the medical checkup data screen 4000 changes to reflect the employee's sightline direction that is currently detected.

The specification unit 65 is mainly implemented by processes performed by the CPU 601 and specifies the employee's observing point position on the display 217 in the communication terminal 40 based on the image data received by the transmission-reception unit 61 every time the transmission-reception unit 61 receives the image data.
The generator 66 is mainly implemented by processes performed by the CPU 601 and generates the medical checkup data screen.
The storing/reading unit 69 stores various data in the storage unit 600 and reads various data from the storage unit 600.
Next, processes and operations in this embodiment are described below with reference to FIGS. 10 to 14. FIG. 10 is a sequence diagram illustrating operation of carrying out a remote consultation.
First, just like the videoconference session, the employee and the industrial physician start the remote consultation using the communication terminals 10 and 40. At this point, the face of the user and at least a part of the room where the user resides at a counterpart site are displayed on the display 217 at a site where the user communicating with the counterpart user resides. As the industrial physician switches the current screen into an input screen and inputs the employee's user ID during the consultation, the accepting unit 42 receives input of the user ID in S21. Subsequently, the transmission-reception unit 41 transfers the input user ID to the consultation management system 60 in S22.
Next, using the user ID accepted in S22 described above as a retrieval key, the storing/reading unit 69 of the consultation management system 60 searches through the user management table in the storage unit 600 (shown in FIG. 7) to read the user personal data indicating the corresponding user name, user sex, and user age for the user with the input user ID in S23. Furthermore, using the user ID accepted in S22 described above as the retrieval key, the storing/reading unit 69 searches through the medical checkup management table in the storage unit 600 (shown in FIG. 8) to read the medical checkup management data related to the corresponding user checkup items, user past medical history, and user lifestyle habits in S24. Next, as shown in FIG. 3, the generator 66 generates screen data of the medical checkup data screen 1000 (an example of the first screen data) that includes the user personal data and the medical checkup management data. In addition, as shown in FIG. 4, the generator 66 generates screen data of the medical checkup data screen 4000 (an example of the second screen data) that includes the user personal data and the medical checkup management data in S25. At this point, the observing point marker v and the message in the reception status display area 4110 have not been included yet.
Next, the transmission-reception unit 61 transfers the screen data of the medical checkup data screen 1000 to the communication terminal 10 in S26-1. As a result, the transmission-reception unit 11 in the communication terminal 10 receives the screen data of the medical checkup data screen 1000. Subsequently, in the communication terminal 10, the display controller 13 displays the medical checkup data screen 1000 shown in FIG. 3 on the display 217 in the communication terminal 10 in S27.
In addition, the transmission-reception unit 61 in the consultation management system 60 transfers the screen data of the medical checkup data screen 4000 to the communication terminal 40 in S26-2. As a result, the transmission-reception unit 41 in the communication terminal 40 receives the screen data of the medical checkup data screen 4000. Subsequently, in the communication terminal 40, the display controller 43 displays the medical checkup data screen 4000 shown in FIG. 4 on the display 217 in the communication terminal 40 in S28.
Next, FIGS. 11 and 12 are sequence diagrams illustrating operation of displaying a medical checkup data screen including a message. FIG. 11 is a sequence diagram illustrating operation of displaying a medical checkup data screen including a message. FIG. 12 is a flowchart illustrating operation of displaying a message on the industrial-physician-side screen.
First, in the consultation room X, the lighting unit 31 in the sightline detection device 30 emits infrared light to the employee face, and the image capture unit 32 receives the reflected light to acquire the image data regarding the image including the employee eye in S41. The emission and reception operation are performed at a predetermined interval (e.g., every 0.5 seconds). Subsequently, the sightline detection device 30 transfers the image data from the connection unit 38 to the connection unit 18 in the communication terminal 10 in S42.
Next, the transmission-reception unit 11 in the communication terminal 10 transfers the image data to the consultation management system 60 via the communication network 9 in S43. As a result, the transmission-reception unit 41 in the communication terminal 40 receives the image data. The transmission/reception process of the image data described above is performed sequentially every time the sightline detection device 30 transfers the image data to the communication terminal 10 in S42.
Next, in the consultation management system 60, the determination unit 64 determines whether or not the image data is received from the communication terminal 10 in S44. Subsequently, the generator 66 generates screen data including a message in S45. It should be noted that the observing point marker v has not been included at that point. Here, a process in step S45 is described below in detail referring to FIG. 12.
If the determination unit 64 determines that the image data is received (YES in S101), as shown in FIG. 4, the generator 66 generates screen data of the medical checkup data screen 4000 including the receiving message indicating that the image data is being received in the reception status display area 4110 in S102. For example, as shown in FIG. 4, a message “receiving user's image data” is displayed as the receiving message. By contrast, if the determination unit 64 determines that the image data is not received in S101, the generator 66 generates screen data of the medical checkup data screen 4000 including the not-received message indicating that the image data has not been received yet in the reception status display area 4110 in S103. For example, a message “user's image data has not been received yet” is displayed as the not-received message. It should be noted that it is possible not to display a message if the image data has not been received.
Referring back to FIG. 11, the transmission-reception unit 61 in the consultation management system 60 transfers the image data generated in S45 to the communication terminal 40 in S46. As a result, the transmission-reception unit 41 in the communication terminal 40 receives the image data. Subsequently, in the communication terminal 40, the display controller 43 displays the medical checkup data screen 4000 shown in FIG. 4 on the display 217 in the communication terminal 40 in S47.
Next, operation of displaying the observing point marker v is described below with reference to FIGS. 13 and 14. FIG. 13 is a sequence diagram illustrating operation of displaying a medical checkup data screen including an observing point marker. FIG. 14 is a flowchart illustrating operation of generating the medical checkup data screen including the observing point marker.
First, as shown in FIG. 13, after the industrial physician presses the “display observing point marker” button 4210 shown in FIG. 4, the accepting unit 42 accepts that the “display observing point marker” button 4210 is pressed in S61.
Next, the transmission-reception unit 41 in the communication terminal 40 transfers a request for the screen data including the observing point marker to the consultation management system 60 in S62. As a result, the transmission-reception unit 61 in the consultation management system 60 receives the request for the screen data including the observing point marker.
Next, the generator 66 in the consultation management system 60 generates the screen data including the observing point marker v in S63. Here, a process of generating the medical checkup data screen is described below with reference to FIG. 14.
First, the determination unit 64 in the consultation management system 60 determines whether or not the transmission-reception unit 61 receives the request for the screen data including the observing point marker in S121. Subsequently, in S121, if the determination unit 64 determines that the request has not been received yet (NO in S121), the determination unit 64 repeats the step in S121.
If the determination unit 64 determines that the request has been received (YES in S121), the specification unit 65 specifies coordinate data indicating a position of pupil against a position of corneal reflex of the eye based on the image data in S122. In addition, by searching through the sightline position management table in FIG. 9A using the coordinate data specified in S122 as the retrieval key, the specification unit 65 specifies a display position of the observing point marker v by reading corresponding display position information in S123.
Next, the generator 66 superimposes the observing point marker v at the display position specified in S123 described above on the medical checkup data in S124.
After that, the determination unit 64 determines whether or not new image data is received in S125. Subsequently, in S125, if the determination unit 64 determines that the new image data is received (YES in S125), the process goes back to the step in S121. By contrast, in S125, if the determination unit 64 determines that the new image data has not been received yet (NO in S125), the determination unit 64 repeats the step in S125. For example, the repetition process is performed every one second.
As shown in FIG. 4, if the observing point marker v is kept displaying on the medical checkup data screen 4000, the industrial physician might feel that it is difficult to recognize the medical checkup data screen 4000 in some cases. Therefore, it is possible to switch the observing point marker v from being displayed to not being displayed.
Referring to FIG. 13, the transmission-reception unit 61 in the consultation management system 60 transfers the screen data of the medical checkup data screen including the observing point marker v to the communication terminal 40 in S64. As a result, the transmission-reception unit 41 in the communication terminal 40 receives the screen data of the medical checkup data screen including the observing point marker v. Subsequently, in the communication terminal 40, as shown in FIG. 4, the display controller 43 displays the medical checkup data screen 4000 including the observing point marker v on the display 217 in the communication terminal 40 in S65.
As described above, by displaying the observing point marker v on the display 217 in the communication terminal 40 on the industrial physician's side, the industrial physician can carry out the remote consultation considering the employee's sightline just like the face-to-face consultation.
For example, as shown in FIG. 4, in case of displaying the observing point marker v at a position different from the employee's name even if the industrial physician confirms the employee's name through the communication, the industrial physician can recognize that the employee is in some kind of abnormal condition such as depression.
Especially, if positions where the observing point marker v vary frequently under control of the display controller 43 based on the image data transferred from the communication terminal 10 sequentially, the industrial physician can further recognize that the employee is in abnormal condition more easily since the employee's sightline is unstable.
Numerous additional modifications and variations are possible in light of the above teachings. It is therefore to be understood that, within the scope of the appended claims, the disclosure of this patent specification may be practiced otherwise than as specifically described herein.
For example, while the above-described embodiment describes the case where an image of both eyes of the user is used to detect the user's sightline, at least one eye of the user may be captured as long as the user's sightline can be detected. For instance, if the user's dominant eye can be specified, the user's sightline may be detected using the image of the user's dominant eye.
