[0002] There is known a subjective optometry device that measures optical characteristics such as the eye refractive power of a subject's eye by placing an optical element in front of the subject's eye and presenting a test optotype to the subject's eye through the optical element. For example, a subjective optometry device described in Patent Document 1 includes an eye refractive power measurement unit, an optotype presenting unit, and a controller. The eye refractive power measurement unit switches an optical element to be placed in the eye examination window from among a plurality of optical elements included in a correction optical system by a drive unit. The optotype presenting unit switches a test optotype to be presented to the subject's eye. The controller detects a user's operation on an operation panel, and transmits a drive signal to the eye refractive power measurement unit and the optotype presenting unit based on the detected operation.

[0011] <Summary> The subjective optometry system exemplified in the present disclosure includes a subjective optometry device and a first information processing device. The subjective optometry device has a corrective optical system that changes the optical characteristics of a target light beam presented to the subject's eye, and is used to subjectively measure the optical characteristics of the subject's eye. The first information processing device is an information processing device connected to the subjective optometry device (hereinafter, the first information processing device may be referred to as a "connection device"). The optometry control program according to the present disclosure includes a drive control application program and a self-optometry application program. The drive control application program is a program for realizing an application (drive control application) that transmits a drive signal that controls the drive of the subjective optometry device to the subjective optometry device. The self-optometry application program is a program for realizing an application (self-optometry application) that automatically progresses the optometry based on the answers input by the subject.

[0012] The drive control application program is executed by the control unit of the first information processing device, whereby the instruction signal acquisition step and the drive signal transmission step are executed by the first information processing device. In the instruction signal acquisition step, the first information processing device acquires an instruction signal that instructs the subjective optometry device to operate. In the drive signal transmission step, the first information processing device transmits a drive signal that causes the subjective optometry device to perform the operation instructed by the acquired instruction signal. The first information processing device can be remotely accessed by a second information processing device (hereinafter, sometimes referred to as a "remote control device") that is another information processing device connected via a network. In this case, the first information processing device can acquire, via the network, the instruction signal input by the user to the second information processing device in the instruction signal acquisition step.

[0013] The self-eye examination application program is executed by the control unit of the first information processing device, whereby the answer acquisition step and the instruction signal generation step are executed by the first information processing device. In the answer acquisition step, the first information processing device acquires an answer input by a subject who visually recognizes a presented optotype. In the instruction signal generation step, the first information processing device generates an instruction signal that instructs an operation of the subjective eye examination device based on the acquired answer.

[0014] According to the technology exemplified in the present disclosure, when a command signal is input by a user (examiner) to a second information processing device remotely accessing a first information processing device, the input command signal is acquired by the first information processing device. Next, a drive signal for executing the commanded operation is transmitted from the first information processing device to the subjective eye examination device. Therefore, the user can smoothly perform the subject's eye examination from a remote location different from the subject's location. Furthermore, by executing the self-eye examination application, the subject's eye examination is appropriately performed without the examiner proceeding with the eye examination. Therefore, the subjective eye examination is appropriately performed with a reduced burden on the examiner.

[0015] Various devices can be used for the first information processing device (connection device) that executes the eye examination control program and the second information processing device (remote control device) that remotely accesses the first information processing device. For example, a personal computer (hereinafter referred to as "PC") may be used as at least one of the first information processing device and the second information processing device. Also, a server, a mobile terminal, a smartphone, or the like may be used as at least one of the first information processing device and the second information processing device. The number of second information processing devices that can remotely access the first information processing device may be one or more.

[0016] In addition, at least one of the first information processing device and the second information processing device may be configured by combining multiple devices. For example, the first information processing device may be configured by a device such as a personal computer and a dedicated controller having a controller and a storage device.

[0017] In addition, the storage device that stores the eye examination control program can be appropriately selected. For example, the eye examination control program may be stored in a storage device built into the first information processing device, or in a storage device that is detachable from the first information processing device. The eye examination control program may be stored in a storage device built into the dedicated controller described above. In addition, the eye examination control program may be stored in multiple storage devices.

[0018] The first information processing device may further execute an eye examination method switching step of switching between self-eye examination, which is an eye examination performed by a self-eye examination application program, and remote eye examination, which is an eye examination performed in response to an instruction signal input to the second information processing device. In this case, each of the self-eye examination and the remote eye examination is appropriately performed according to various situations. For example, it is possible to select an appropriate eye examination method from the self-eye examination and the remote eye examination according to the situation of the facility or store where the subjective eye examination device is installed, or the personnel deployed. It is also possible to select an appropriate eye examination method according to the subject's situation. There is no need to prepare a device for self-eye examination and a device for remote eye examination separately, which is also highly convenient.

[0019] When an eye examination for a subject is started, the self-eye examination may be performed before the remote eye examination in a state where remote access to the first information processing device has already been established for one or more second information processing devices. In this case, the self-eye examination is started first, so that for subjects who can perform the self-eye examination, the eye examination is automatically performed without the examiner proceeding with the eye examination. Furthermore, in cases where the subject cannot perform the self-eye examination, the remote access is switched to the remote eye examination by the second information processing device to which the remote access has already been established. Therefore, the eye examination is performed more smoothly than when a connection between the first information processing device and the second information processing device is established after a decision is made to switch from the self-eye examination to the remote eye examination.

[0020] In the eye examination method switching step, when the situation of the self-eye examination being performed satisfies a predetermined condition or when an instruction to switch to remote eye examination is input, the method may be switched to remote eye examination by at least one of the second information processing devices to which remote access is established. In this case, when a situation occurs in which the subject cannot perform the self-eye examination, the method is appropriately switched from the self-eye examination to the remote eye examination.

[0021] The conditions of the self-eye examination situation when switching from the self-eye examination to the remote eye examination can be appropriately selected. For example, the control unit may determine that the conditions for switching to the remote eye examination are met when a predetermined time has passed without an answer being input from the subject. The control unit may also determine that the conditions for switching to the remote eye examination are met when the answer input by the subject is inappropriate.

[0022] When the situation of the self-eye examination being performed satisfies a predetermined condition or when an instruction to switch to a remote eye examination is input, the first information processing device may cause the second information processing device to which remote access is established to execute a notification operation for the user. In this case, the user of the second information processing device can easily grasp that a situation in which the self-eye examination cannot be performed has occurred. Therefore, switching from the self-eye examination to the remote eye examination can be performed more smoothly.

[0023] It is also possible to change the method of switching between the self-eye examination and the remote eye examination. For example, the first information processing device may appropriately switch between the self-eye examination and the remote eye examination in response to an instruction input by a user (for example, an examiner).

[0024] The second information processing device may be connected to or equipped with at least one of an operation unit that outputs an operation signal when operated by a user and a microphone that outputs a voice signal (hereinafter, simply referred to as an "operation unit / microphone"). In the instruction signal input step, the instruction signal may be input by at least one of an operation signal and a voice signal. In this case, by using an information processing device to which the operation unit / microphone is connected or equipped as the second information processing device, it becomes unnecessary to configure the subjective eye examination device so that the operation unit / microphone can be connected. As a result, the subjective eye examination can be performed appropriately with the configuration of the subjective eye examination device simplified.

[0025] The operation unit may be at least one of general-purpose devices such as a keyboard, a mouse, a touch panel, etc. Also, a dedicated operation unit (such as a joystick) suitable for inputting operation instructions in subjective eye examination may be used.

[0026] The first information processing device may be connected to or equipped with a camera. The first information processing device may further execute a display step of displaying on a display device a remote eye examination screen to be visually recognized by a user who inputs an instruction signal to the second information processing device. The remote eye examination screen may include an area in which an operation image including information on the optical characteristics of a target light beam to be presented to the subject's eye is displayed, and an area in which an image captured by a camera connected to or equipped with the first information processing device can be displayed. In this case, a user (examiner) of the second information processing device can check an image captured by a camera connected to the first information processing device (e.g., an image captured by the subject, etc.) together with the operation image during the remote eye examination. Therefore, the remote eye examination can be performed more smoothly.

[0027] Another aspect of the subjective optometry system exemplified in the present disclosure includes a subjective optometry device and a first information processing device. The subjective optometry device has a correction optical system that changes the optical characteristics of a target light beam presented to the subject's eye, and a drive unit that drives the correction optical system, and is used to subjectively measure the optical characteristics of the subject's eye. The first information processing device is an information processing device connected to the subjective optometry device. The optometry control program according to the present disclosure includes a drive control application program for realizing an application (drive control application) that transmits a drive signal that controls the drive of the subjective optometry device to the subjective optometry device. The drive control application program is executed by the control unit of the first information processing device, whereby the instruction signal acquisition step and the drive signal transmission step are executed by the first information processing device. In the instruction signal acquisition step, the first information processing device acquires an instruction signal that instructs the subjective optometry device to operate. In the drive signal transmission step, the first information processing device transmits a drive signal that causes the subjective optometry device to perform an operation instructed by the acquired instruction signal to the drive unit via the relay unit. The relay unit converts the drive signal transmitted from the first information processing device into a drive signal capable of controlling the drive unit. The first information processing device can be remotely accessed by a second information processing device, which is another information processing device connected via a network. In this case, the first information processing device acquires, via the network, an instruction signal input by a user to the second information processing device in the instruction signal acquisition step.

[0028] In a conventional subjective optometry device, a drive signal for controlling the drive of the drive unit may be transmitted from a dedicated controller to the drive unit via a relay unit. The drive signal must be converted by the relay unit into a drive signal capable of controlling the drive unit. In this case, a method for using a conventional subjective optometry device in combination with an information processing device may involve transmitting a control signal from the information processing device to the controller, and then transmitting the drive signal from the controller to the drive unit via the relay unit. However, this method requires signal processing in the controller, which may cause problems such as delays in the operation of the drive unit.

[0029] In contrast, according to the technology exemplified in the present disclosure, a drive signal is transmitted from a first information processing device connected to a subjective eye examination device to a drive unit via a relay unit. In other words, the signal transmitted from the first information processing device does not need to pass through a controller. Therefore, problems such as operational delays of the subjective eye examination device are unlikely to occur. Furthermore, when an instruction signal is input by a user (examiner) to a second information processing device remotely accessing the first information processing device, the input instruction signal is acquired by the first information processing device, and a drive signal for executing the instructed operation is transmitted from the first information processing device. Therefore, the user can smoothly perform an eye examination of the subject from a remote location different from the subject's location.

[0030] <Embodiment> (System Configuration) Hereinafter, one of the typical embodiments of the present disclosure will be described with reference to the drawings. As shown in FIG. 1, a subjective optometry system 100 of this embodiment includes a subjective optometry device 1 and a first information processing device 2A. The subjective optometry device 1 is used to subjectively measure the optical characteristics of the subject's eye. The optical characteristics of the subject's eye measured by the subjective optometry device 1 of this embodiment are the eye refractive power. The measured eye refractive power may be at least one of the spherical power, cylindrical power, and astigmatism axis angle of the subject's eye. The first information processing device 2A is connected to the subjective optometry device 1. Hereinafter, the first information processing device 2A may be referred to as a connection device. In addition, the first information processing device 2A is remotely accessed by a second information processing device 2B, which is another information processing device, via a network 5. Each device will be described in detail below.

[0031] The subjective optometry apparatus 1 includes an eye refractive power measuring unit 10, an optotype presenting unit 15, and a relay unit 19.

[0032] The eye refractive power measuring unit 10 includes a correction optical system 11 and a drive unit 12. The correction optical system 11 changes the optical characteristics of the visual target light beam presented to the subject's eye. That is, the correction optical system 11 changes at least one of the spherical power, cylindrical power, astigmatism axis angle, polarization characteristics, and aberration amount of the visual target light beam. As an example, the correction optical system 11 of this embodiment changes the optical characteristics of the visual target light beam by switching the optical element arranged in the test window in front of the subject's eye among the multiple optical elements. In the correction optical system 11 of this embodiment, a lens disk for the left eye and a lens disk for the right eye are used, in which multiple optical elements are arranged on the same circumference. Each of the lens disk for the left eye and the lens disk for the right eye may be one or more. For example, at least one of a spherical lens, a cylindrical lens, a cross cylinder lens, a rotary prism, and a wavefront modulation element may be used as the optical element. The driving unit 12 changes the optical characteristics of the visual target light beam by driving the correction optical system 11. In this embodiment, the driving unit 12 drives the correction optical system 11 by rotating each of the lens disks for the left eye and the lens disks for the right eye to switch the optical element arranged in the test window. For example, a step motor or the like can be used as the driving unit 12. The driving unit 12 is driven in response to a driving signal.

[0033] The optotype presenting unit 15 presents a test optotype (for example, at least one of a Landolt ring optotype and a letter) to the eye to be examined, and switches the test optotype to be presented to the eye to be examined. In detail, the optotype presenting unit 15 includes an optotype presenting section 16 and a driving section 17. The optotype presenting section 16 presents a test optotype to the eye to be examined. For example, the optotype presenting section 16 may be at least one of a space-saving optotype projection device that projects the test optotype to the eye to be examined via a concave mirror, a chart projector that projects the test optotype on a screen, and a display that displays the test optotype. The optotype presenting section 16 is disposed at approximately the same height as the eye refractive power measuring unit 10 so that the distance from the eye to be examined is a predetermined optical distance. The driving section 17 drives the optotype presenting section 16 to switch the test optotype to be presented to the eye to be examined. The driving section 17 is driven in response to a driving signal.

[0034] The relay unit 19 relays a drive signal between the first information processing device 2A and the drive units 12 and 17. In this embodiment, the system of the drive signal output from the first information processing device 2A is different from the system of the drive signal capable of controlling at least one of the drive units 12 and 17. The relay unit 19 of this embodiment converts the drive signal received from the first information processing device 2A into a drive signal capable of controlling the drive units 12 and 17, and transmits it to the drive units 12 and 17. Furthermore, as an example, when the relay unit 19 of this embodiment receives one drive signal for driving both the two drive units 12 and 17 from the first information processing device 2A, it converts the received one drive signal into two drive signals for driving each of the two drive units 12 and 17, and transmits them to each of the two drive units 12 and 17.

[0035] The first information processing device 2A and the second information processing device 2B will be described. At least one of various information processing devices capable of processing various information can be adopted as the first information processing device 2A and the second information processing device 2B. As an example, a personal computer (hereinafter referred to as "PC") is used as the first information processing device 2A and the second information processing device 2B of the present embodiment. However, the information processing device that can function as the first information processing device 2A and the second information processing device 2B of the present embodiment is not limited to a PC. For example, a server, a mobile terminal, a smartphone, or the like may be used as at least one of the first information processing device 2A and the second information processing device 2B. At least one of the first information processing device 2A and the second information processing device 2B may be configured by a plurality of devices. For example, the first information processing device 2A may be configured by a dedicated controller having a controller and a storage device, and a personal computer.

[0036] The first information processing device 2A and the second information processing device 2B are connected in a communicable state via a network (e.g., the Internet) 5. In the example shown in FIG. 1, a case is illustrated in which a plurality of second information processing devices 2B are connected to one first information processing device 2A. However, one second information processing device 2B may be connected to one first information processing device 2A. Also, one second information processing device 2B may be connected to a plurality of first information processing devices 2A.

[0037] The first information processing device 2A is disposed at a site (e.g., an eyeglass store or a hospital) where subjective eye examination is performed on a subject. The first information processing device 2A includes a CPU 21A and a storage device 22A. The CPU 21A is a control unit (controller) that controls the first information processing device 2A. The storage device 22A can store programs and various data. In this embodiment, an eye examination control program is stored in the storage device 22A.

[0038] The first information processing device 2A is connected to the subjective optometry device 1 (specifically, the relay unit 19 of the subjective optometry device 1) in a communicable state. The connection standard between the first information processing device 2A and the subjective optometry device 1 may be various standards such as LAN. The first information processing device 2A is also connected to the objective optometry device 3 in a communicable state. The objective optometry device 3 objectively measures the optical characteristics of the subject's eye (for example, at least one of spherical power, cylindrical power, and astigmatism axis angle). The connection standard between the first information processing device 2A and the objective optometry device 3 may be various standards such as LAN. The objective optometry device 3 may be connected to the relay unit 19. The measurement results by the objective optometry device 3 may be stored in a storage device provided in the relay unit 19.

[0039] The first information processing device 2A is connected to a camera 31A, a microphone 32A, a speaker 33A, an operation unit 34A, and a display unit 35A. The camera 31A captures an image. In particular, the camera 31A in this embodiment is used to capture a moving image of the subject. The microphone 32A converts sound into an audio signal and outputs it. The speaker 33A converts the audio signal into sound. The operation unit 34A is operated by a user (e.g., a subject, etc.) to input various instructions. For the operation unit 34A, at least one of a keyboard, a mouse, a touch panel, etc. may be used. In addition, a dedicated operation unit (e.g., a joystick, etc.) suitable for inputting answers to subjective eye examinations may be used as the operation unit 34A. The display unit 35A displays various images. For the display unit 35B, various devices capable of displaying images (e.g., at least one of a monitor, a display, and a projector, etc.) may be used.

[0040] The second information processing device 2B is disposed at a base of an examiner who can proceed with an eye examination using the subjective eye examination device 1. The second information processing device 2B includes a CPU 21B and a storage device 22B. The CPU 21B is a control unit (controller) that controls the second information processing device 2B. The storage device 22A can store programs, various data, and the like.

[0041] The second information processing device 2B is connected to a camera 31A, a microphone 32A, a speaker 33A, an operation unit 34A, and a display unit 35A. As for these devices, various devices can be used, similar to the devices connected to the first information processing device 2A described above.

[0042] (Applications and eye examination methods) The application installed in the first information processing device 2A of this embodiment will be described. As described above, the storage device 22A of the first information processing device 2A stores an eye examination control program for executing the eye examination control process (see FIG. 2). The eye examination control program includes a drive control application program for executing a drive control application and a self-eye examination application program for executing a self-eye examination application. The drive control application transmits a control signal for controlling the drive of the subjective eye examination device 1 to the subjective eye examination device 1. The self-eye examination application automatically proceeds with the eye examination by the subjective eye examination device 1 based on the answer input by the subject. The drive control application program for executing the drive control application and the self-eye examination application program for executing the self-eye examination application may be constructed and prepared separately, or may be incorporated into one program.

[0043] A subjective eye examination method that can be performed by the subjective eye examination system 100 of this embodiment will be described. In the subjective eye examination system 100 of this embodiment, self-eye examination and remote eye examination are performed. The self-eye examination is an eye examination performed by a self-eye examination application. That is, in the self-eye examination, the eye examination proceeds automatically based on the answers input by the examinee. The remote eye examination is an eye examination performed in response to a signal (instruction signal) input to the second information processing device 2B. The second information processing device 2B can be placed at a location different from the location where the subjective eye examination device 1 is placed. Therefore, according to the remote eye examination, the examiner can smoothly proceed with the eye examination even if the examiner's location and the examinee's location are different.

[0044] (Ophthalmology control processing) An example of an eye examination control process executed by the first information processing device 2A of the subjective eye examination system 100 of this embodiment will be described with reference to Fig. 2 to Fig. 5. In the eye examination control process, for example, a process for controlling a self-eye examination, a process for controlling a remote eye examination, and a process for switching between a self-eye examination and a remote eye examination are executed. When an instruction to start a subjective eye examination of a subject's eye is input to the first information processing device 2A, the CPU 21A of the first information processing device 2A executes the eye examination control process exemplified in Fig. 2 according to an eye examination control program.

[0045] First, when an eye examination of a subject is started, the CPU 21A judges whether or not remote access to the first information processing device 2A of one or more second information processing devices 2B has been established (S1).

[0046] In this embodiment, the "state where remote access is established" refers to a state where an instruction input to any one of a plurality of information processing devices connected via a network 5 is transmitted to the other information processing devices via the network 5. For example, when remote access of the second information processing device 2B to the first information processing device 2A is established, an instruction input by a user to the second information processing device 2B is transmitted to the first information processing device 2A. As a result, the second information processing device 2B enters a state as if it were accessing the first information processing device 2A at a different location.

[0047] Various methods can be used to establish remote access of the second information processing device 2B to the first information processing device 2A. For example, the second information processing device 2B may establish remote access to the first information processing device 2A by using a remote access service (RAS). In this case, the second information processing device 2B is in a state where it can access applications other than the self-eye examination application and the drive control application in the first information processing device 2A. Also, the remote access may be established by transmitting only signals necessary for controlling the eye examination control process (see FIG. 2) by the first information processing device 2A from the second information processing device 2B to the first information processing device 2A.

[0048] If at least one second information processing device 2B has already remotely accessed the first information processing device 2A (S1: YES), the process proceeds directly to S3, and the self-eye examination process is executed. If none of the second information processing devices 2B has remotely accessed the first information processing device 2A (S1: NO), the CPU 21A establishes remote access with at least one of the second information processing devices 2B (S2), and then executes the self-eye examination process (S3). That is, when the eye examination of the examinee is started, the self-eye examination process (S3) is executed before the remote eye examination process (S6) in a state in which the remote access of the second information processing device 2B to the first information processing device 2A is established. Therefore, for the examinee who can perform the self-eye examination, the eye examination is automatically performed without the examiner proceeding with the eye examination. Furthermore, as will be described later in detail, in the case where the examinee cannot perform the self-eye examination, the self-eye examination is switched to the remote eye examination by the second information processing device 2B with which the remote access has already been established. Therefore, the eye examination can be performed more smoothly than when a connection (remote access) between the first information processing device 2A and the second information processing device 2B is established after a decision is made to switch from self-eye examination to remote eye examination.

[0049] The self-eye examination process will be described with reference to FIG. 3. The processes of S11 to S18 in the self-eye examination process are executed by a self-eye examination application. First, the CPU 21A acquires objective eye examination results (S11). As an example, the first information processing device 2A of the present embodiment acquires objective eye examination results for the same subject from an objective eye examination device 3 (see FIG. 1) connected via a LAN or a relay unit 19 or the like. However, the CPU 21A may acquire objective eye examination results for the same subject via, for example, a removable memory or a network 5 or the like. In addition, the objective eye examination results may be input by a user via an operation unit 34A or the like. If there are no objective eye examination results for the same subject, the process of S11 may be omitted.

[0050] The CPU 21A determines the first examination content in the self-eye examination. The CPU 21A generates an instruction signal for instructing the operation of the subjective eye examination device 1 to perform the determined examination (S12). If the result of the objective eye examination for the same subject is obtained in S11, the first examination content (i.e., the optical element to be initially placed in the examination window of the correction optical system 11 and the type and size of the optotype to be presented by the optotype presenting unit 16) is determined in S12 according to the result of the objective eye examination (for example, the ocular refractive power (at least one of the spherical power, the cylindrical power, and the cylindrical axis angle) measured for the same eye to be examined). As a result, the process of the self-eye examination is simplified. If the result of the objective eye examination is not obtained in S11, the default examination content may be determined as the first examination content in S12.

[0051] Next, the CPU 21A acquires the instruction signal generated in S12 or S18 (described later) and transmits a drive signal to the subjective optometry device 1 to cause the subjective optometry device 1 to execute the operation instructed by the instruction signal (S13). As a result, the subjective optometry device 1 appropriately executes the instructed operation. In detail, in S13 of this embodiment, at least one of a drive signal for the drive unit 12 to place the optical element determined in S12 or S18 in the test window of the correction optical system 11 and a drive signal for the drive unit 17 to present the optotype presenting unit 16 with the optotype determined in S12 or S18 is transmitted to the subjective optometry device 1. Note that, when transmitting the drive signal to the subjective optometry device 1, the CPU 21A causes the speaker 33A to output a guidance voice according to the test contents. Therefore, the subject can properly understand the test contents and then see the presented test optotype.

[0052] In this embodiment, the driving signal is transmitted from the first information processing device 2A to the driving units 12 and 17 via the relay unit 19 (see FIG. 1) described above. Therefore, the signal transmitted from the first information processing device 2A does not need to go through a dedicated controller or the like. Therefore, signal processing by a dedicated controller or the like is omitted, and eye examination is performed more smoothly.

[0053] In the self-eye examination, the subject understands the contents of the examination through the guidance voice, visually recognizes the test target presented to the subject's eye by the subjective eye examination device 1, and inputs an answer based on the visual recognition result into the first information processing device 2A. As an example, in the present embodiment, the subject operates a dedicated operation unit 34A suitable for inputting answers to subjective eye examinations, thereby inputting the answer. However, the answer may be input by a general operation unit 34A. Also, the answer may be input by an audio signal converted by the microphone 32A.

[0054] The CPU 21A judges whether or not a response from the subject has been input (S15). If a response has been input (S15: YES), the input response is stored in the storage device 22A (S16). Next, if the series of self-eye examinations has not yet been completed (S17: NO), the CPU 21A determines the next examination content based on the response from the subject acquired in S15, and generates an instruction signal (S18).

[0055] As an example, in this embodiment, when the answer from the subject acquired in S15 is correct, the CPU 21A determines the next test content so that the optotype presenting unit 16 presents an optotype with a visual acuity value one step higher than that previously presented (for example, an optotype with a size one step smaller). When the answer from the subject acquired in S15 is incorrect, the CPU 21A determines the next test content so that the optotype presenting unit 16 presents an optotype with a visual acuity value one step lower than that previously presented (for example, an optotype with a size one step larger). In addition to switching the optotype, the CPU 21A determines the correction power of the optical element to be placed in the test window of the correction optical system 11 as the next test content. Next, the CPU 21A generates an instruction signal to instruct the next operation of the subjective optometry device 1 to perform the determined test. That is, the instruction signal generated in S18 is at least one of an instruction signal for placing the determined optical element in the test window of the correction optical system 11 and an instruction signal for presenting the determined optotype on the optotype presenting unit 16. Thereafter, the process returns to S13, and a drive signal is transmitted to the subjective optometry device 1 in response to the instruction signal generated in S18.

[0056] In addition, when the processes of S13 to S18 are repeatedly executed and the series of self-eye examinations is successfully completed (S17: YES), the remote eye examination process (see S6 in FIG. 2 and FIG. 4) is not executed, and the eye examination control process (see FIG. 2) ends as it is.

[0057] If no answer is input from the subject (S15: NO), it is determined whether the self-eye examination situation satisfies a predetermined condition that is likely to be inappropriate (S20). As an example, in this embodiment, if a predetermined time has passed without an answer being input from the subject after the drive signal is transmitted in S13, it is determined that the predetermined condition is satisfied. Also, if the answer input by the subject is inappropriate, it is determined that the predetermined condition is satisfied. If it is determined that the predetermined condition is satisfied (S20: YES), the process returns to the eye examination control process (see FIG. 2), and the eye examination method is switched from the self-eye examination to the remote eye examination. At this time, for example, a process of stopping the output of sound, screen, etc. in the self-eye examination may be performed.

[0058] Moreover, if the subject has not input a response (S15: NO) and the conditions for the self-eye examination are not met (S20: NO), the CPU 21A judges whether or not a switching instruction to remote eye examination has been input (S21). When it is difficult for the subject to perform the self-eye examination, the subject can input a switching instruction to remote eye examination to the first information processing device 2A by the operation unit 34A or by voice or the like. If a switching instruction has not been input (S21: NO), the process returns to S15, and the processes of S15, S20, and S21 are repeated. If a switching instruction is input (S21: YES), the process returns to the eye examination control process (see FIG. 2), and the eye examination method is switched from the self-eye examination to the remote eye examination.

[0059] Returning to the description of FIG. 2, if the self-eye examination by the self-eye examination process (S3) is not completed, the CPU 21A transmits a notification instruction via the network 5 to one or more second information processing devices 2B that have established remote access to the first information processing device 2A (S4). The notification instruction is an instruction to execute a notification operation to notify a user (e.g., an examiner) that the self-eye examination by the first information processing device 2A has not been completed. The notification operation may be performed by at least one of a method such as outputting a sound or displaying an image. By performing the notification operation, the user of the second information processing device 2B can more easily grasp that a situation in which the self-eye examination cannot be performed has occurred in the first information processing device 2A.

[0060] Next, the CPU 21A judges whether or not there is a response from the user (e.g., examiner, etc.) of the second information processing device 2B (S5). If there is no response from the examiner from any of the second information processing devices 2B (S5: NO), it is impossible to execute the remote eye examination, and the judgment of S5 is repeated to enter a standby state. If the user of any of the second information processing devices 2B is in a state in which the remote eye examination can proceed and inputs a response instruction to the second information processing device 2B (S5), the CPU 21A executes the remote eye examination process (S6).

[0061] The remote eye examination process will be described with reference to Fig. 4. The remote eye examination process is executed by a drive control application. First, the CPU 21A displays a remote eye examination screen 50 (see Fig. 5) on the display unit 35B of the second information processing device 2B used by the examiner who proceeds with the remote eye examination (S31).

[0062] As shown in FIG. 5, the remote eye examination screen 50 in this embodiment includes an operation image area 51 and a photographed image area 52. The CPU 21A displays an operation image including information on the optical characteristics of the target light beam to be presented to the subject's eye in the operation image area 51. In the operation image of this embodiment, values ​​related to the optical characteristics of the target light beam to be presented to the subject's eye are displayed for each type of optical characteristics. The examiner can specify a value for a desired type among a plurality of types of optical characteristics (spherical power, cylindrical power, and astigmatism axis angle, etc.). The CPU 21A also displays an image photographed by the camera 31A connected to (or mounted on) the first information processing device 2A in the photographed image area 52. Therefore, the examiner can check the image photographed by the camera 31A (for example, an image of the examinee, etc.) together with the operation image during the remote eye examination. This allows the remote eye examination to be performed more smoothly.

[0063] Moreover, when the CPU 21A acquires the objective eye examination result for the same subject, it displays the acquired result on the remote eye examination screen 50 (S32). As described above, the objective eye examination result may be acquired by various methods.

[0064] During the remote eye examination, the audio signal input from the microphone 32A to the first information processing device 2A is converted into audio by the speaker 33B of the second information processing device 2B. Also, the audio signal input from the microphone 32B to the second information processing device 2B is converted into audio by the speaker 33A of the first information processing device 2A. Therefore, the examiner and the subject can have a conversation during the remote eye examination. Also, an image captured by the camera 31B may be displayed on the display unit 35A of the first information processing device 2A.

[0065] During the remote optometry, the examiner using the second information processing device 2B can input, by at least one of the operation unit 34B and the microphone 32B, an instruction signal for instructing the operation of the subjective optometry device 1. The instruction signal is at least one of an instruction signal for placing an optical element determined by the examiner in the examination window of the correction optical system 11, and an instruction signal for presenting an optotype determined by the examiner on the optotype presenting unit 16.

[0066] As an example, in this embodiment, the examiner can input an instruction signal by operating a mouse as the operation unit 34B. The mouse includes a wheel rotation detection unit, a wheel click detection unit, a left click detection unit, and a right click detection unit. The wheel rotation detection unit detects the rotation direction and amount of rotation of a wheel rotatably provided on the mouse body. The wheel click detection unit detects that the wheel has been clicked (pressed). The left click detection unit detects that the left button provided on the mouse body has been clicked (pressed). The right click detection unit detects that the right button provided on the mouse body has been clicked (pressed). The mouse outputs detection signals from each of the wheel rotation detection unit, wheel click detection unit, left click detection unit, and right click detection unit to an information processing device (e.g., the second information processing device 2B, etc.).

[0067] When a click is detected by at least one of the wheel click detection unit, the left click detection unit, and the right click detection unit, the CPU of the information processing device (at least one of the first information processing device 2A and the second information processing device 2B in this embodiment) switches the type of optical characteristic (for example, either spherical power or cylindrical power) of the visual target light beam presented to the subject's eye by the subjective optometry device 1, whose value is to be changed. In addition, the CPU of the information processing device changes the value of one of the types of optical characteristics (the type specified by the click in this embodiment) according to the amount of rotation and the direction of rotation of the wheel detected by the wheel rotation detection unit. Therefore, the examiner can intuitively and smoothly change the value of the optical characteristic of the visual target light beam by rotating the wheel. In other words, the rotation operation is similar between the case where the optical element is switched using a dedicated controller equipped with an operation unit that can be rotated and the case where the optical element is switched by rotating the wheel. Therefore, the optical element can be intuitively switched as in the case where a dedicated controller is used.

[0068] The CPU may switch the value related to the optical element when the wheel click detection unit detects a click of the wheel. In this case, for example, depending on whether the cursor displayed on the display unit 35A matches with "+" or "-" on the remote optometry screen 50 when the click is detected, it may be determined whether to switch the value related to the optical element to "+" or "-". By using the click of the wheel, it becomes easy to finely switch the value related to the optical element. In addition, the switching of the value of the optical element according to the rotation amount and the rotation direction of the wheel and the switching of the value of the optical element according to the click of the wheel may be used together. In this case, the examiner can appropriately use the intuitive switching of the optical element by rotating the wheel and the fine switching of the optical element by clicking the wheel depending on the situation.

[0069] The CPU 21A judges whether or not an instruction signal has been input to the second information processing device 2B (S33). When an instruction signal is input to the second information processing device 2B, the input instruction signal is acquired by the first information processing device 2A via the network 5. When an instruction signal is input and acquired (S33: YES), the CPU 21A transmits to the subjective optometry device 1 a drive signal for causing the subjective optometry device 1 to execute the operation instructed by the acquired instruction signal (S34). As described above, the drive signal is transmitted from the first information processing device 2A to the drive units 12 and 17 via the relay unit 19 (see FIG. 1). After that, the process returns to S33. The processes of S33 to S36 are repeated until the remote optometry is completed (S36: NO). When an instruction to complete the remote optometry is input (S36: YES), the optometry control process ends.

[0070] The technology disclosed in the above embodiment is merely an example. Therefore, it is possible to change the technology exemplified in the above embodiment. For example, it is possible to execute only a part of the technology exemplified in the above embodiment. As an example, the subjective optometry system 100 may execute only one of the self-eye examination and the remote eye examination. In addition, when both the self-eye examination and the remote eye examination are executed, the self-eye examination and the remote eye examination may be appropriately switched according to an instruction from the user. In this case, the subjective optometry system 100 may set the eye examination method to be executed from the self-eye examination and the remote eye examination according to an instruction input by the user. The subjective optometry system 100 may launch an application for executing the set eye examination method when the power is turned on or when the eye examination starts.

[0071] The process of acquiring an instruction signal at S13 in FIG. 3 and S33 in FIG. 4 is an example of an "instruction signal acquiring step." The process of transmitting a drive signal at S13 in FIG. 3 and S34 in FIG. 4 is an example of a "drive signal transmitting step." The process of acquiring an answer at S15 in FIG. 3 is an example of an "answer acquiring step." The process of generating an instruction signal at S18 in FIG. 3 is an example of an "instruction signal generating step." The process of switching the eye examination method at S20 and S21 in FIG. 3 is an example of an "eye examination method switching step." The process of transmitting a notification instruction at S4 in FIG. 2 is an example of a "notification step." [Explanation of symbols]
