Description

Technical Field

[0001] The technology disclosed in this specification relates to an information processing apparatus that measures the characteristics of a subject when the subject moves.

Background Art

[0002] When a driver drives a vehicle and moves on a road, it is useful to appropriately measure and evaluate the characteristics of the driver (for example, the ability to perceive targets such as hazards, self-evaluation ability, self-control ability, risk-taking tendency, level of risk, etc.). For example, when issuing or renewing a driver's license, such characteristics during driving are measured, and based on the results of the characteristic measurement, it is determined whether to issue or renew the driver's license, or appropriate training or training is conducted based on the results of the characteristic measurement, then the average risk of the driver can be reduced, which ultimately leads to the prevention of traffic accidents. In particular, the elderly may have a decline in cognitive function, and in addition, the elderly and those who have developed eye diseases such as glaucoma may have a narrow or missing visual field, so the risk during driving tends to be high, and it is extremely useful to measure the characteristics during driving for such people.

[0003] Conventionally, as a method for evaluating the risk, which is one of the characteristics of a driver during driving, an animated image that simulates the driver's field of view is displayed in front of the subject using an image display device (liquid crystal monitor or projector), and when a hazard (automobile, bicycle, pedestrian, etc.) included in the animated image is recognized, a test is conducted to have the subject answer by voice or button operation, etc., and based on the results of the test, the risk of the subject during driving is evaluated (for example, see Non-Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0005] During actual driving of an automobile, it is also possible to compensate for an increase in risks caused by a decline in cognitive function, narrowed or missing fields of vision, etc. by reducing the driving speed of the automobile. In the above conventional technology, since the subject cannot perform an operation (instruction) to reduce the driving speed of the automobile during the test, it is impossible to perform a risk assessment based on such compensatory behavior, and there is room for improvement in terms of the appropriateness of measuring the characteristics of the driver.

[0006] Note that such problems are not limited to the case of measuring the characteristics of a driver when driving an automobile, but are also common problems in the case of measuring the characteristics of a driver when driving other types of vehicles (such as bicycles) or when measuring the characteristics of a pedestrian when moving on foot.

[0007] This specification discloses a technology capable of solving the above-described problems.

Means for Solving the Problems

[0008] The technology disclosed in this specification can be realized, for example, in the following forms.

[0009] (1) The information processing apparatus disclosed in this specification is an information processing apparatus that measures the characteristics of a subject when the subject moves, and includes a speed selection instruction acquisition unit, a display control unit, a position designation acquisition unit, and a characteristic measurement unit. The speed selection instruction acquisition unit acquires a speed selection instruction for selecting the speed of the movement by the subject. The display control unit executes speed variable display processing for causing an image display unit to display a simulated movement image, which is a moving image including a scene that simulates the field of view of a person moving along a preset course and includes at least one target, in such a manner that the speed of the movement is set according to the speed selection instruction. The position designation acquisition unit receives a position designation for designating a specific position in the simulated movement image by the subject. The characteristic measurement unit measures the characteristic based on a pointing result correlated with whether or not there is a position designation for correctly designating the position of the target at a specific timing when a scene including each target of the simulated movement image in the speed variable display processing is displayed, and the content of the speed selection instruction, and outputs characteristic information indicating the measurement result of the characteristic.

[0010] Thus, in this information processing apparatus, the display control unit executes speed variable display processing for causing the simulated movement image to be displayed in such a manner that the movement speed is set according to the speed selection instruction acquired by the speed selection instruction acquisition unit, and the characteristic measurement unit measures the characteristics of the subject based on the content of the speed selection instruction in addition to a pointing result correlated with whether or not there is a position designation for correctly designating the position of the target at a specific timing when a scene including each target of the simulated movement image during the speed variable display processing is displayed. Therefore, according to this information processing apparatus, it is possible to measure the characteristics of the subject based on the action of the subject selecting the movement speed by himself / herself, and it is possible to improve the appropriateness of the measurement of the characteristics of the subject.

[0011] (2) In the above information processing apparatus, the display control unit further executes a speed-fixed display process of causing the image display unit to display the simulated moving image in a manner in which the speed of the movement is fixed to a preset reference speed, and the characteristic measurement unit may be configured to measure the characteristic based on the pointing result in the speed-fixed display process. According to this information processing apparatus, it is possible to measure the characteristics of the subject by comparing the pointing results in each of the speed-fixed display process in which the moving speed is fixed to the reference speed and the speed-variable display process in which the subject can select the moving speed, and the appropriateness of the characteristic measurement of the subject can be effectively improved.

[0012] (3) In the above information processing apparatus, the display control unit executes the speed-variable display process after executing the speed-fixed display process, and the speed selection instruction acquisition unit may be configured to acquire the speed selection instruction after the execution of the speed-fixed display process and before the execution of the speed-variable display process. According to this information processing apparatus, the subject will select the moving speed in the speed-variable display process based on the feeling of his own pointing result in the speed-fixed display process, and the self-evaluation ability and self-control ability of the subject can be accurately grasped, and the appropriateness of the characteristic measurement of the subject can be effectively improved.

[0013] (4) In the above information processing apparatus, the characteristic may be configured to include the target object perception ability of the subject and the self-control ability of the subject. According to this information processing apparatus, the appropriateness of the characteristic measurement of the subject including the target object perception ability of the subject and the self-control ability of the subject can be effectively improved.

[0014] (5) In the above information processing apparatus, the characteristic includes the self-evaluation ability of the subject, the information processing apparatus further includes a self-evaluation acquisition unit that acquires the self-evaluation of the pointing result by the subject, and the characteristic measurement unit may be configured to measure the characteristic based on the self-evaluation. According to this information processing apparatus, it is possible to measure the characteristics of the subject based on the self-evaluation of the pointing result by the subject, and the appropriateness of the characteristic measurement of the subject including the self-evaluation ability of the subject can be effectively improved.

[0015] (6) In the above information processing apparatus, the characteristic measurement unit may be configured to determine the self-evaluation ability of the subject based on the difference between the self-evaluation and the actual pointed-out result. According to this information processing apparatus, the appropriateness of the characteristic measurement of the subject including the self-evaluation ability of the subject can be further effectively improved.

[0016] (7) In the above information processing apparatus, the speed selection instruction acquisition unit may be configured to acquire the speed selection instruction during the variable speed display process, and the display control unit may be configured to change the speed of the movement according to the speed selection instruction during the variable speed display process. According to this information processing apparatus, it is possible to perform characteristic measurement of the subject based on an action closer to the actual movement environment, that is, changing the movement speed (accelerating or decelerating) during movement, and effectively improve the appropriateness of the characteristic measurement of the subject.

[0017] (8) In the above information processing apparatus, the characteristic includes the risk during the movement of the subject. When there is no position designation that correctly designates the position of the target object at the specific timing during the variable speed display process, the characteristic measurement unit may be configured to determine that the risk is lower when there is a speed selection instruction to reduce the speed of the movement than when there is no speed selection instruction to reduce the speed of the movement. When the target object cannot be recognized at the above specific timing during the variable speed display process, when there is a speed selection instruction to reduce the speed of the movement (hereinafter, also referred to as "deceleration instruction"), it is considered that a compensatory action has been taken because the subject is meta-aware of the lack of his or her own recognition ability. On the other hand, when there is no deceleration instruction, it is considered that no compensatory action has been taken because the subject is not meta-aware of the lack of his or her own recognition ability. According to this information processing apparatus, when such a compensatory action is taken, it is determined that the risk is lower than when no compensatory action is taken, so that the appropriateness of the risk measurement as a characteristic of the subject can be improved.

[0018] (9) In the above information processing apparatus, the characteristic includes the risk during the movement of the subject. When there is no position specification that correctly specifies the position of the target object at the specific timing during the fixed-speed display process, and there is no position specification that correctly specifies the position of the target object at the specific timing during the variable-speed display process, the risk is determined to be lower when there is an instruction to select a speed that reduces the speed of the movement than when there is no such instruction to select a speed that reduces the speed of the movement. When the target object cannot be recognized during both the fixed-speed display process and the variable-speed display process, if there is a deceleration instruction, it is considered that a compensatory action has been taken because the subject is meta-aware of the lack of their own recognition ability. On the other hand, if there is no deceleration instruction, it is considered that no compensatory action has been taken because the subject is not meta-aware of the lack of their own recognition ability. According to this information processing apparatus, when such a compensatory action is taken, the risk is determined to be lower compared to the case where no compensatory action is taken, so the appropriateness of risk measurement as a characteristic of the subject can be improved.

[0019] (10) In the above information processing apparatus, when there is no position specification that correctly specifies the position of the target object at the specific timing during the fixed-speed display process, and there is a position specification that correctly specifies the position of the target object at the specific timing during the variable-speed display process, and there is a speed selection instruction to reduce the speed of the movement, it may be configured to determine that the risk is lower than when there is no speed selection instruction to reduce the speed of the movement. According to this information processing apparatus, even if the target object can be recognized during the variable-speed display process, when the target object cannot be recognized during the fixed-speed display process and there is a deceleration instruction, it is considered that a compensatory action has been taken because the lack of its own recognition ability has been meta-cognized. On the other hand, when there is no deceleration instruction, it is considered that no compensatory action has been taken because the lack of its own recognition ability has not been meta-cognized. According to this information processing apparatus, when such a compensatory action is taken, it is determined that the risk is lower compared to the case where no compensatory action is taken, so the appropriateness of risk measurement as a characteristic of the subject can be improved.

[0020] (11) In the above information processing apparatus, the display control unit may be configured to execute the variable-speed display process after executing the fixed-speed display process. According to this information processing apparatus, for a scene including a target object that could not be recognized during the fixed-speed display process, the level of meta-cognitive ability can be accurately grasped based on the presence or absence of a speed selection instruction to reduce the speed of the movement in the subsequent variable-speed display process, and the appropriateness of the characteristic measurement of the subject can be effectively improved.

[0021] (12) In the above information processing apparatus, the simulated moving image includes the target object (visible automobiles, bicycles, pedestrians, etc.) representing an apparent risk and the target object (blind spots, etc.) representing a potential risk. The characteristics include the risk during the movement of the subject. The characteristic measurement unit measures the risk caused by visual field defect based on the pointing result at the specific timing when a scene including the target object representing the apparent risk is displayed, and measures the risk caused by cognitive function decline based on the pointing result at the specific timing when a scene including the target object representing the potential risk is displayed. Such a configuration may be adopted. According to this information processing apparatus, the appropriateness of risk measurement caused by visual field defect and the appropriateness of risk measurement caused by cognitive function decline can be improved.

[0022] (13) In the above information processing apparatus, the simulated moving image may be a moving image that simulates the visual field of a person moving on the course while driving a vehicle. According to this information processing apparatus, the appropriateness of characteristic measurement of the subject when the subject moves while driving a vehicle can be improved.

[0023] (14) In the above information processing apparatus, it may further be configured to include the image display unit. According to this information processing apparatus, the device configuration for performing characteristic measurement can be simplified.

[0024] (15) In the above information processing system, it may be configured to include the information processing apparatus according to any one of claims 1 to 8 and an image display device as the image display unit. According to this information processing system, a system capable of appropriately measuring the characteristics of a subject when the subject moves while visually recognizing a simulated moving image can be provided.

[0025] Note that the technology disclosed in this specification can be realized in various forms. For example, it can be realized in the form of an information processing apparatus, an information processing system, an information processing method, a computer program for realizing those methods, a non-transitory recording medium recording the computer program, and the like.

Mode for Carrying Out the Invention

[0027] A. First Embodiment: It is useful to appropriately measure the characteristics of a driver when the driver drives an automobile and moves on a road. For example, when issuing or renewing a driver's license, such a driving characteristic measurement is performed, and based on the result of the characteristic measurement, it is determined whether to issue or renew the driver's license, or appropriate training or training is performed based on the result of the characteristic measurement. By doing so, the average risk of the driver can be reduced, which in turn leads to the prevention of traffic accidents. In particular, the cognitive function of the elderly may decline, and those who have developed eye diseases such as the elderly and glaucoma may have a narrowed or defective visual field, so the risk during driving tends to increase. On the other hand, during actual driving of an automobile, it is also possible to compensate for an increase in risk caused by a decline in cognitive function, a narrow or defective visual field, etc. by reducing the driving speed of the automobile. Therefore, it is extremely useful to measure the characteristics during driving in consideration of such compensatory behaviors. An example (an example applied to the information processing device 300) of using the technology disclosed in this specification to appropriately measure the characteristics of a driver during driving will be described below.

[0028] A-1. Configuration of the information processing device 300: FIG. 1 is an explanatory diagram showing the schematic configuration of the information processing apparatus 300 in the first embodiment, and FIG. 2 is a block diagram showing the schematic configuration of the information processing apparatus 300 in the first embodiment. The information processing apparatus 300 of the present embodiment is a device for measuring the characteristics of the subject EX when the subject EX drives an automobile and moves on a road. More specifically, the information processing apparatus 300 visually presents a simulated driving image SI that simulates the field of view of a human driving an automobile and moving on a preset course to the subject EX, and performs a hazard recognition test for determining whether the subject EX recognizes each hazard (hazardous location in the moving environment) included in the simulated driving image SI. Based on the result of the hazard recognition test, it is a device for measuring the characteristics of the subject EX when the subject EX drives an automobile and moves on a road.

[0029] As shown in FIGS. 1 and 2, in the present embodiment, a tablet-type terminal is used as the information processing apparatus 300. The information processing apparatus 300 includes a control unit 310, a storage unit 330, a display unit 352, an operation input unit 358, and an interface unit 359. These units are connected to each other via a bus 390 so as to be communicable with each other.

[0030] The display unit 352 of the information processing apparatus 300 is configured by, for example, a liquid crystal display, an organic EL display, or the like, and displays various images and information. The display unit 352 is an example of the image display unit in the claims. The operation input unit 358 is configured by, for example, buttons, a microphone, or the like, and receives operations and instructions from the administrator or the subject EX. In the present embodiment, the display unit 352 has a touch panel and also functions as the operation input unit 358. The interface unit 359 is configured by, for example, a LAN interface, a USB interface, or the like, and communicates with other devices by wire or wirelessly.

[0031] The storage unit 330 of the information processing apparatus 300 is configured by, for example, a ROM, a RAM, a hard disk drive (HDD), etc., and stores various programs and data, or is used as a work area or a temporary storage area for data when executing various programs. For example, the storage unit 330 stores a characteristic measurement program CP, which is a computer program for executing a subject characteristic measurement process described later. The characteristic measurement program CP is provided, for example, in a state of being stored in a computer-readable recording medium (not shown) such as a CD-ROM, a DVD-ROM, or a USB memory, and is stored in the storage unit 330 by being installed in the information processing apparatus 300. Note that the characteristic measurement program CP does not necessarily have to be stored in the storage unit 330 of the information processing apparatus 300. The characteristic measurement program CP may be stored on an external server, and the function of the characteristic measurement program CP may be realized on the information processing apparatus 300 by the information processing apparatus 300 accessing the characteristic measurement program CP via a network.

[0032] In addition, the moving image data MID is stored in the storage unit 330 of the information processing apparatus 300. The moving image data MID is data representing the above-described simulated operation image SI. The simulated operation image SI is a moving image configured at a predetermined frame rate (for example, 70 fps). The simulated operation image SI is a moving image that simulates the field of view of a human driving an automobile and moving along a preset course, and includes a plurality of scenes including hazards Hn (n = 1, 2,...). The hazard Hn includes at least one of an obvious hazard such as an automobile, a bicycle, or a pedestrian, and a potential hazard such as an intersection with poor visibility, a blind spot of a building or a parked vehicle. For example, in a certain scene in the simulated operation image SI, as shown in FIG. 1, a pedestrian as the hazard H1 jumps out from the side of the road. In this specification, the scene in the simulated operation image SI may be an image represented by one frame constituting the simulated operation image SI, or an image having a predetermined temporal length represented by a plurality of consecutive frames. Also, the number of hazards Hn included in one scene may be one or a plurality. The simulated operation image SI corresponds to the simulated moving image in the claims.

[0033] In addition, in the present embodiment, the moving image data MID is data that can change the displayed simulated operation image SI so that the traveling speed of the automobile is set according to a speed selection instruction by a subject EX described later. The speed selection instruction is at least one of a deceleration instruction for decreasing the speed, an acceleration instruction for increasing the speed, and a speed maintenance instruction for maintaining the current speed. Also, the moving image data MID representing the simulated operation image SI may be created by, for example, CG software, or may be created using an image captured by a camera while driving an automobile on a real road. Further, the moving image data MID may include audio data representing an audio simulating the traveling sound of the automobile or the like.

[0034] In addition, correct answer information RAI is stored in the storage unit 330 of the information processing apparatus 300. The correct answer information RAI is information that specifies the timing at which a scene including each hazard Hn is displayed (the display time of the frame including each hazard Hn) and the position of each hazard Hn (the coordinates of the image area representing the hazard Hn on the frame) in the simulated driving image SI. Further, in the storage unit 330 of the information processing apparatus 300, position designation information LDI, speed selection instruction information VII, characteristic information CHI, and self-evaluation information SEI, which will be described later, are stored during the subject characteristic measurement process. The content of these pieces of information will be described in accordance with the description of the subject characteristic measurement process described later.

[0035] The control unit 310 of the information processing apparatus 300 is configured by, for example, a CPU or the like, and controls the operation of the information processing apparatus 300 by executing a computer program read from the storage unit 330. For example, the control unit 310 executes the subject characteristic measurement process described later by reading and executing the characteristic measurement program CP from the storage unit 330. More specifically, the control unit 310 functions as a display control unit 312, a self-evaluation acquisition unit 315, a position designation acquisition unit 316, a speed selection instruction acquisition unit 317, and a characteristic measurement unit 318 for executing the subject characteristic measurement process described later. The functions of these units will be described in accordance with the description of the subject characteristic measurement process described later.

[0036] A-2. Subject Characteristic Measurement Process: Next, the subject characteristic measurement process executed by the information processing apparatus 300 of the present embodiment will be described. FIG. 3 is a flowchart showing the content of the subject characteristic measurement process in the first embodiment. FIGS. 4 and 5 are explanatory diagrams showing an example of a state in which a user interface (UI) is displayed on the display unit 352 during the subject characteristic measurement process in the first embodiment, and FIGS. 6 and 7 are explanatory diagrams showing an example of a method for measuring characteristics in the subject characteristic measurement process in the first embodiment.

[0037] The subject characteristic measurement process is a process of performing a hazard recognition test that allows the subject EX to visually recognize the simulated driving image SI and determines whether the subject EX correctly recognizes each hazard Hn included in the simulated driving image SI, and measuring the characteristics of the subject EX when the subject EX drives a vehicle and moves on the road based on the result of the hazard recognition test. During the hazard recognition test, when the subject EX recognizes something that the subject EX considers to be a hazard Hn while the simulated driving image SI is being displayed on the display unit 352, the subject EX is instructed to perform a touch operation on the position where the hazard Hn is shown on the display unit 352. The subject characteristic measurement process is started, for example, in response to an instruction to start the process being input by the subject EX or the administrator via the operation input unit 358 of the information processing apparatus 300.

[0038] When the subject characteristic measurement process is started, the display control unit 312 of the information processing apparatus 300 starts displaying (playing back) the simulated driving image SI on the display unit 352 based on the moving image data MID stored in the storage unit 330 (S110). This display process of the simulated driving image SI is hereinafter referred to as the "constant speed display process P1". In the constant speed display process P1, the display control unit 312 displays the simulated driving image SI in a mode in which the traveling speed V is fixed to a preset reference speed V1 (for example, 40 km / h). That is, in the constant speed display process P1, the subject EX cannot change the traveling speed by a speed selection instruction.

[0039] When the speed-fixed display process P1 starts, the position-specification acquisition unit 316 of the information processing apparatus 300 starts accepting a position specification for designating a specific position in the simulated driving image SI by the subject EX, and starts recording position-specification information LDI indicating the history of the position specification (S120). The position-specification information LDI is information indicating the position (coordinates) on the simulated driving image SI designated by the subject EX through a touch operation on the display unit 352 and the time when the touch operation was performed (the time on the simulated driving image SI). By referring to the position-specification information LDI, it is possible to grasp in which scene in the simulated driving image SI and at which position the subject EX recognized an object as a hazard Hn. The acquired / updated position-specification information LDI is stored in the storage unit 330. When a position specification (touch operation on the display unit 352) is made by the subject EX, the control unit 310 may execute a reaction process (for example, output of sound, some display on the display unit 352, etc.) indicating that the position specification has been accepted.

[0040] The display control unit 312 of the information processing apparatus 300 monitors whether the speed-fixed display process P1 has been completed (S130). If it is determined that the speed-fixed display process P1 has been completed (S130: YES), the process proceeds to S132.

[0041] Next, the self-evaluation acquisition unit 315 of the information processing apparatus 300 acquires a self-evaluation SE of the pointing rate by the subject EX (S132). Here, the pointing rate means the ratio of the number of hazards Hn correctly recognized by the subject EX to the number of hazards Hn included in the simulated driving image SI in the hazard recognition test. The pointing rate is an index value correlated with whether or not there is a position specification for correctly designating the position of the hazard Hn at a specific timing when a scene including each hazard Hn of the simulated driving image SI is displayed, and is an example of the pointing result in the claims.

[0042] The self-evaluation acquisition unit 315 causes the display unit 352 to display a user interface UI1 for acquiring a self-evaluation SE of the pointing rate by the subject EX, as shown in FIG. 4, for example. This user interface UI1 includes, in addition to a message prompting the self-evaluation SE of the pointing rate (for example, a message such as "To what extent were you able to touch the points that should be confirmed for safe driving in the current scene?"), a user interface for inputting the self-evaluation SE of the pointing rate (for example, a straight line indicating each stage from a pointing rate of 0% (left end) to a pointing rate of 100% (right end), and a pointer for sliding on the straight line and designating a point on the straight line). The subject EX moves the pointer to a position corresponding to the self-evaluation SE of the pointing rate by a touch operation on the display unit 352. The self-evaluation acquisition unit 315 acquires the self-evaluation SE of the pointing rate by the subject EX based on the position of the pointer. The acquired self-evaluation SE is stored in the storage unit 330 as self-evaluation information SEI indicating the self-evaluation SE.

[0043] Next, the speed selection instruction acquisition unit 317 of the information processing apparatus 300 acquires a speed selection instruction VI for selecting a traveling speed by the subject EX (S134). For example, as shown in FIG. 5, the speed selection instruction acquisition unit 317 causes the display unit 352 to display a user interface UI2 for acquiring a speed selection instruction VI for selecting a traveling speed by the subject EX. This user interface UI2 includes a message prompting a speed selection instruction (for example, a message such as "The speed in the current scene was 40 km / h. You will drive the same road again. At what speed will you drive? The higher the pointing rate at the confirmation points and the higher the speed, the higher the score. Please aim for the highest score possible."), and a user interface for selecting a traveling speed (for example, icons indicating nine speed options marked at 5 km intervals from 20 km / h to 60 km / h). The subject EX inputs the speed selection instruction VI by selecting an icon corresponding to a desired traveling speed through a touch operation on the display unit 352. The speed selection instruction acquisition unit 317 acquires the speed selection instruction VI by the subject EX based on the selected icon. The acquired speed selection instruction VI is stored in the storage unit 330 as speed selection instruction information VII indicating the speed selection instruction VI. Hereinafter, the traveling speed selected by the speed selection instruction VI is referred to as the selected speed V2. Note that the example of the message prompting the speed selection instruction above is for avoiding the behavior of the subject EX trying to increase the pointing rate by selecting an excessively low traveling speed not based on the subject's own ability or characteristics, and is useful for grasping the true characteristics of the subject EX.

[0044] Next, the display control unit 312 of the information processing apparatus 300 causes the display unit 352 to start displaying the simulated operation image SI again based on the moving image data MID (S140). The display process of this simulated operation image SI is hereinafter referred to as "variable speed display process P2". In the variable speed display process P2, the display control unit 312 causes the simulated operation image SI to be displayed in such a manner that the traveling speed V is set according to the speed selection instruction VI by the subject EX. That is, the display control unit 312 causes the display unit 352 to display the simulated operation image SI so that the traveling speed V becomes the selected speed V2 selected by the speed selection instruction VI. Once the display of the simulated operation image SI in the variable speed display process P2 has started, the traveling speed V is fixed to the selected speed V2. In this way, in the present embodiment, since the subject EX does not need to perform an operation for the speed selection instruction VI while visually recognizing the simulated operation image SI, the load on the subject EX is reduced, and the hazard perception ability of the subject EX can be measured more accurately.

[0045] When the variable speed display process P2 is started, the position designation acquisition unit 316 of the information processing apparatus 300 starts accepting a position designation for designating a specific position in the simulated operation image SI by the subject EX, and starts recording position designation information LDI indicating the history of the position designation, in the same manner as during the speed fixed display process P1 described above (S150). The acquired and updated position designation information LDI is stored in the storage unit 330.

[0046] The display control unit 312 of the information processing apparatus 300 monitors whether the variable speed display process P2 has been completed (S160). When it is determined that the variable speed display process P2 has been completed (S160: YES), the process proceeds to S170.

[0047] When the fixed-speed display process P1 and the variable-speed display process P2 are completed, the characteristic measurement unit 318 of the information processing apparatus 300 refers to the correct answer information RAI stored in advance in the storage unit 330, the position designation information LDI created / updated during the execution of the fixed-speed display process P1 and the variable-speed display process P2, and the self-evaluation information SEI and the speed selection instruction information VII acquired between the fixed-speed display process P1 and the variable-speed display process P2 and stored in the storage unit 330, and starts measuring the characteristics during driving for the subject EX as detailed below.

[0048] The characteristic measurement unit 318 of the information processing apparatus 300 determines the pointing rate R1 in the fixed-speed display process P1 (S170). Specifically, the characteristic measurement unit 318 calculates the pointing rate R1 in the fixed-speed display process P1 and compares the pointing rate R1 with the reference pointing rate Rs. The reference pointing rate Rs is set in advance as the value of the pointing rate required for safe driving and is stored in the storage unit 330. When the pointing rate R1 in the fixed-speed display process P1 is lower than the reference pointing rate Rs (that is, when the pointing rate R1 is relatively low), the characteristic measurement unit 318 sets the value of the first coefficient i to "-1", and when the pointing rate R1 is equal to or higher than the reference pointing rate Rs (that is, when the pointing rate R1 is relatively high), the characteristic measurement unit 318 sets the value of the first coefficient i to "0".

[0049] Also, the characteristic measurement unit 318 of the information processing apparatus 300 determines the self-evaluation SE of the pointing rate in the speed-fixed display process P1 (S180). Specifically, the characteristic measurement unit 318 calculates the difference (R1 - SE) between the actual pointing rate R1 in the speed-fixed display process P1 and the self-evaluation SE of the pointing rate by the subject EX specified by the self-evaluation information SEI stored in the storage unit 330, and compares the difference (R1 - SE) with a first threshold Th1 and a second threshold Th2 (where Th1 < Th2). When the difference (R1 - SE) is less than the first threshold Th1 (that is, when the self-evaluation SE of the pointing rate is excessive with respect to the actual pointing rate R1), the characteristic measurement unit 318 sets the value of the second coefficient j to "-1". When the difference (R1 - SE) is greater than or equal to the first threshold Th1 and less than or equal to the second threshold Th2 (that is, when the self-evaluation SE of the pointing rate is close to the actual pointing rate R1), the characteristic measurement unit 318 sets the value of the second coefficient j to "0". When the difference (R1 - SE) exceeds the second threshold Th2 (that is, when the self-evaluation SE of the pointing rate is too small with respect to the actual pointing rate R1), the characteristic measurement unit 318 sets the value of the second coefficient j to "1".

[0050] Also, the characteristic measurement unit 318 of the information processing apparatus 300 determines the selection of speed (S190). Specifically, the characteristic measurement unit 318 compares the selected speed V2, which is the traveling speed in the variable-speed display process P2 selected by the speed selection instruction VI, with the reference speed V1, which is the preset traveling speed in the speed-fixed display process P1. When the selected speed V2 is faster than the reference speed V1 (that is, when the subject EX makes a selection to increase the speed from the traveling speed in the speed-fixed display process P1 in the speed selection scene after the speed-fixed display process P1), the characteristic measurement unit 318 sets the value of the third coefficient k to "1". When the selected speed V2 is less than or equal to the reference speed V1 (that is, when the subject EX maintains the traveling speed in the speed-fixed display process P1 or makes a selection to decrease the speed from the traveling speed in the speed selection scene after the speed-fixed display process P1), the characteristic measurement unit 318 sets the value of the third coefficient k to "-1".

[0051] Also, the characteristic measurement unit 318 of the information processing apparatus 300 determines the pointing rate R2 in the variable speed display process P2 (S200). Specifically, the characteristic measurement unit 318 calculates the pointing rate R2 in the variable speed display process P2 and compares the pointing rate R2 with the reference pointing rate Rs described above. When the pointing rate R2 in the variable speed display process P2 is lower than the reference pointing rate Rs (that is, when the pointing rate R2 is relatively low), the characteristic measurement unit 318 sets the value of the fourth coefficient l to "-1", and when the pointing rate R2 is equal to or higher than the reference pointing rate Rs (that is, when the pointing rate R2 is relatively high), the characteristic measurement unit 318 sets the value of the fourth coefficient l to "0". In this embodiment, the value of the reference pointing rate Rs used for the determination of the pointing rate R2 in the variable speed display process P2 is the same as the value of the reference pointing rate Rs used for the determination of the pointing rate R1 in the fixed speed display process P1. However, the value of the reference pointing rate Rs used for the determination of the pointing rate R2 in the variable speed display process P2 may be different from the value of the reference pointing rate Rs used for the determination of the pointing rate R1 in the fixed speed display process P1. For example, considering that the display of the simulated operation image SI is the second time in the variable speed display process P2, the value of the reference pointing rate Rs used for the determination of the pointing rate R2 in the variable speed display process P2 may be set to a value higher than the value of the reference pointing rate Rs used for the determination of the pointing rate R1 in the fixed speed display process P1.

[0052] The determination processes of S170 to S200 do not necessarily have to be executed in the above order, and the execution order of these determination processes can be set arbitrarily. Also, a plurality of determination processes may be executed in parallel.

[0053] Next, the characteristic measurement unit 318 of the information processing apparatus 300 measures the characteristics of the subject EX based on the combination (i, j, k, l) of the first to fourth coefficients set in the determination processes of S170 to S200, creates characteristic information CHI indicating the characteristics of the subject EX, and outputs the characteristic information CHI (S210). As shown in FIGS. 6 and 7, in the present embodiment, for each of the combinations (i, j, k, l) of the values of the first to fourth coefficients, different characteristics (24 types of characteristics) are associated with each other. The characteristic measurement unit 318 identifies the characteristics of the subject EX based on the combination (i, j, k, l) of the values of the first to fourth coefficients set in the determination processes of S170 to S200, and displays the content of the characteristic information CHI indicating the identified characteristics on the display unit 352.

[0054] In this embodiment, the characteristics of the subject EX measured by the subject characteristic measurement process include a hazard perception ability, a self-evaluation ability, a self-control ability, and a risk-taking tendency. The hazard perception ability is the ability to detect hazards, and is mainly determined, for example, in six levels ("very high", "high", "somewhat high", "somewhat low", "low", "very low") based on the results of the determination (i.e., the first coefficient i and / or the fourth coefficient l) regarding the pointing rates R1 and R2 in the fixed-speed display process P1 and / or the variable-speed display process P2 (S170, S200). For example, in the characteristic type "1" shown in FIG. 6, since the value of the first coefficient i is "0", the pointing rate R1 in the fixed-speed display process P1 is relatively high, and since the value of the third coefficient k is "1", the subject EX makes a selection to increase the speed from the speed (reference speed V1) in the fixed-speed display process P1 in the scene of selecting the speed (selected speed V2) for the variable-speed display process P2. Furthermore, since the value of the fourth coefficient l is "0", the pointing rate R2 in the variable-speed display process P2 with increased speed is also relatively high. Therefore, in the characteristic type "1" shown in FIG. 6, the hazard perception ability is determined to be "very high". Also, in the characteristic type "13" shown in FIG. 7, since the value of the first coefficient i is "0", the pointing rate R1 in the fixed-speed display process P1 is relatively high, and since the value of the third coefficient k is "1", the subject EX makes a selection to increase the speed from the speed (reference speed V1) in the fixed-speed display process P1 in the scene of selecting the speed (selected speed V2) for the variable-speed display process P2. Furthermore, since the value of the fourth coefficient l is "-1", the pointing rate R2 in the variable-speed display process P2 with increased speed is relatively low. Therefore, in the characteristic type "13" shown in FIG. 7, the hazard perception ability is determined to be "somewhat high".Also, in the characteristic type "20" shown in FIG. 7, since the value of the first coefficient i is "-1", the pointing rate R1 in the speed-fixed display process P1 is relatively low. Also, since the value of the third coefficient k is "-1", the subject EX makes a selection to decrease (or maintain) the speed from the speed (reference speed V1) in the speed-fixed display process P1 in the scene of selecting the speed (selection speed V2) for the variable-speed display process P2. Furthermore, since the value of the fourth coefficient l is "-1", the pointing rate R2 is also relatively low even in the variable-speed display process P2 with the decreased speed. Therefore, in the characteristic type "20" shown in FIG. 7, it is determined that the hazard perception ability is "quite low".

[0055] Also, the self-evaluation ability is the ability to objectively monitor one's own hazard perception ability (i.e., metacognitive ability), and is mainly determined based on the result (i.e., the second coefficient j) of the determination (S180) regarding the self-evaluation SE of the pointing rate, for example, in three levels ("accurate", "over-evaluation (overconfident)", "under-evaluation (underconfident)"). For example, in the characteristic type "1" shown in FIG. 6, since the value of the second coefficient j is "0", the self-evaluation SE of the pointing rate is close to the actual pointing rate R1. Therefore, in the characteristic type "1" shown in FIG. 6, the self-evaluation ability is determined to be "accurate". Also, in the characteristic type "3" shown in FIG. 6, since the value of the second coefficient j is "-1", the self-evaluation SE of the pointing rate is excessive compared to the actual pointing rate R1. Therefore, in the characteristic type "3" shown in FIG. 6, the self-evaluation ability is determined to be "over-evaluation (overconfident)". Also, in the characteristic type "5" shown in FIG. 6, since the value of the second coefficient j is "1", the self-evaluation SE of the pointing rate is less than the actual pointing rate R1. Therefore, in the characteristic type "5" shown in FIG. 6, the self-evaluation ability is determined to be "under-evaluation (underconfident)".

[0056] Furthermore, self-control ability is the ability to select appropriate actions according to the movement environment based on self-evaluation of one's abilities. Mainly, it is determined, for example, in three levels ("high", "standard", "low") based on the result of the determination (i.e., the first coefficient i) regarding the pointing rate R1 in the speed-fixed display process P1 (S170), the result of the determination (i.e., the second coefficient j) regarding the self-evaluation SE of the pointing rate (S180), and the result of the determination (i.e., the third coefficient k) regarding speed selection (S190). For example, in the characteristic type "1" shown in FIG. 6, since the value of the first coefficient i is "0", the pointing rate R1 in the speed-fixed display process P1 is relatively high. Also, since the value of the second coefficient j is "0", the self-evaluation SE of the pointing rate is close to the actual pointing rate R1. Furthermore, since the value of the third coefficient k is "1", the subject EX makes a selection to increase the speed from the speed (reference speed V1) in the speed-fixed display process P1 in the scenario of selecting the speed (selected speed V2) for the variable-speed display process P2. That is, based on the high pointing rate R1 and accurate self-evaluation, the action of increasing the speed is selected. Therefore, in the characteristic type "1" shown in FIG. 6, the self-control ability is determined to be "standard". Also, in the characteristic type "5" shown in FIG. 6, since the value of the first coefficient i is "0", the pointing rate R1 in the speed-fixed display process P1 is relatively high. Also, since the value of the second coefficient j is "1", the self-evaluation SE of the pointing rate is too low compared to the actual pointing rate R1. Furthermore, since the value of the third coefficient k is "1", the subject EX makes a selection to increase the speed from the speed (reference speed V1) in the speed-fixed display process P1 in the scenario of selecting the speed (selected speed V2) for the variable-speed display process P2. That is, despite the self-evaluation SE being too low compared to the actual pointing rate R1, the action of increasing the speed is selected. Therefore, in the characteristic type "5" shown in FIG. 6, the self-control ability is determined to be "low".

[0057] Also, the risk-taking tendency is the tendency to prefer taking risks and is mainly determined, for example, in two levels ("high", "low") based on the result of the determination (i.e., the third coefficient k) of the speed selection (S190). For example, in the characteristic type "1" shown in FIG. 6, since the value of the third coefficient k is "1", the subject EX makes a selection to increase the speed from the speed (reference speed V1) in the speed fixed display process P1 in the scene of selecting the speed (selection speed V2) for the variable speed display process P2. Therefore, in the characteristic type "1" shown in FIG. 6, the risk-taking tendency is determined to be "high". Also, in the characteristic type "2" shown in FIG. 6, since the value of the third coefficient k is "1", the subject EX makes a selection to decrease (or maintain) the speed from the speed (reference speed V1) in the speed fixed display process P1 in the scene of selecting the speed (selection speed V2) for the variable speed display process P2. Therefore, in the characteristic type "2" shown in FIG. 6, the risk-taking tendency is determined to be "low".

[0058] As the output mode of the characteristic information CHI indicating the characteristics by the characteristic measurement unit 318 of the information processing apparatus 300, various modes can be adopted. For example, for the characteristic type assigned to the subject EX, the determination results of each item of the characteristics illustrated in FIGS. 6 and 7 may be displayed on the display unit 352. Alternatively, an explanatory text of the characteristics set based on the determination results of each item of the characteristics (for example, for the characteristic type "1", the explanatory text "You have a very high hazard recognition ability and an accurate self-evaluation ability. Your risk-taking tendency is high, but you have standard self-control ability.") may be displayed on the display unit 352. Alternatively, a symbol indicating the characteristic type assigned to the subject EX (for example, the characteristic type "1") may be displayed on the display unit 352, and the content of the characteristic type may be shown to the subject EX by another means (for example, a separately distributed printed matter). Also, when the pointing rate is calculated for each type of hazard (pedestrians, bicycles, other vehicles, etc.) and the hazards with a low pointing rate are biased towards a specific type, an explanatory text indicating that the recognition ability for the hazards of that type is low may be displayed on the display unit 352.

[0059] As described above, the subject characteristic measurement process for measuring the characteristics of the subject EX when the subject EX drives a vehicle and moves on a road is completed.

[0060] A-3. Effects of the First Embodiment: As described above, the information processing apparatus 300 according to the first embodiment is an apparatus that measures the characteristics of the subject EX when the subject EX drives a vehicle and moves, and includes a speed selection instruction acquisition unit 317, a display control unit 312, a position designation acquisition unit 316, and a characteristic measurement unit 318. The speed selection instruction acquisition unit 317 acquires a speed selection instruction VI for selecting a traveling speed by the subject EX. The display control unit 312 executes a speed variable display process P2 for causing the display unit 352 to display a simulated driving image SI, which is a moving image simulating the field of view of a person moving on a preset course while driving a vehicle and including a scene including at least one hazard Hn, in such a manner that the traveling speed is set according to the speed selection instruction VI. The position designation acquisition unit 316 receives a position designation for designating a specific position in the simulated driving image SI by the subject EX. The characteristic measurement unit 318 measures the characteristics of the subject EX based on the pointing rate R2 correlated with whether or not there is a position designation for correctly designating the position of the hazard Hn at a specific timing when the scene including each hazard Hn of the simulated driving image SI is displayed during the speed variable display process P2, and the content of the speed selection instruction VI (what traveling speed is selected), and outputs characteristic information CHI indicating the measurement result of the characteristics.

[0061] As described above, in the information processing apparatus 300 of the present embodiment, the display control unit 312 executes a speed variable display process P2 for displaying the simulated driving image SI in such a manner that the driving speed is set according to the speed selection instruction VI acquired by the speed selection instruction acquisition unit 317. The characteristic measurement unit 318 measures the characteristics of the subject EX based on the content of the speed selection instruction VI, in addition to the pointing rate R2 that correlates with whether there is a correct position designation of the position of the hazard Hn at a specific timing when a scene including each hazard Hn of the simulated driving image SI during the speed variable display process P2 is displayed. Therefore, according to the information processing apparatus 300 of the present embodiment, it is possible to measure the characteristics of the subject EX based on the action of the subject EX selecting the driving speed of the automobile by himself / herself, and the appropriateness of the characteristic measurement of the subject EX can be improved.

[0062] Further, in the information processing apparatus 300 of the present embodiment, the display control unit 312 further executes a speed fixed display process P1 for displaying the simulated driving image SI on the display unit 352 in a manner where the driving speed is fixed to a reference speed V1 set in advance. Also, the characteristic measurement unit 318 measures the characteristics of the subject EX based on the pointing rate R1 in the speed fixed display process P1, in addition to the pointing rate R2 during the speed variable display process P2 and the content of the speed selection instruction VI. Therefore, according to the information processing apparatus 300 of the present embodiment, it is possible to measure the characteristics of the subject EX by comparing the pointing rates R1 and R2 in the speed fixed display process P1 where the driving speed is fixed to the reference speed V1 and the speed variable display process P2 where the subject EX can select the driving speed, and the appropriateness of the characteristic measurement of the subject EX can be effectively improved.

[0063] In addition, in the information processing apparatus 300 of the present embodiment, the display control unit 312 executes the variable speed display process P2 after executing the fixed speed display process P1. Further, the speed selection instruction acquisition unit 317 acquires the speed selection instruction VI after executing the fixed speed display process P1 and before executing the variable speed display process P2. Therefore, according to the information processing apparatus 300 of the present embodiment, the subject EX selects the traveling speed (selection speed V2) in the variable speed display process P2 based on the feeling (self-evaluation) of the degree of his / her own hazard recognition in the fixed speed display process P1, and the self-evaluation ability and self-control ability of the subject EX can be accurately grasped, and the appropriateness of the characteristic measurement of the subject EX can be effectively improved.

[0064] In addition, in the information processing apparatus 300 of the present embodiment, the characteristics of the subject EX include the hazard perception ability of the subject EX and the self-control ability of the subject EX. As described above, in the information processing apparatus 300 of the present embodiment, the characteristic measurement unit 318 measures the characteristics of the subject EX based on the pointing rate R2 during the variable speed display process P2 and the content of the speed selection instruction VI. Therefore, according to the information processing apparatus 300 of the present embodiment, the appropriateness of the characteristic measurement of the subject EX including the hazard perception ability of the subject EX and the self-control ability of the subject EX can be effectively improved.

[0065] In addition, in the information processing apparatus 300 of the present embodiment, the characteristics of the subject EX include the self-evaluation ability of the subject EX. Further, the information processing apparatus 300 further includes a self-evaluation acquisition unit 315 that acquires a self-evaluation SE of the pointing rate by the subject EX. The characteristic measurement unit 318 measures the characteristics of the subject EX based on the self-evaluation SE, in addition to the pointing rate R2 during the variable-speed display process P2 and the content of the speed selection instruction VI. Therefore, according to the information processing apparatus 300 of the present embodiment, the characteristics of the subject EX can be measured based on the self-evaluation SE of the pointing rate by the subject EX, and the appropriateness of measuring the characteristics of the subject EX including the self-evaluation ability of the subject EX can be effectively improved. In the information processing apparatus 300 of the present embodiment, the characteristic measurement unit 318 determines the self-evaluation ability of the subject EX based on the difference between the self-evaluation SE and the actual pointing rate. Therefore, according to the information processing apparatus 300 of the present embodiment, the appropriateness of measuring the characteristics of the subject EX including the self-evaluation ability of the subject EX can be further effectively improved.

[0066] In addition, the information processing apparatus 300 of the present embodiment includes a display unit 352 that displays the simulated driving image SI. Therefore, according to the information processing apparatus 300 of the present embodiment, the device configuration for measuring the characteristics of the subject EX can be simplified.

[0067] B. Second Embodiment: B-1. Configuration of the Information Processing Apparatus 300 and Subject Characteristic Measurement Process: FIG. 8 is an explanatory diagram showing the schematic configuration of the information processing apparatus 300 in the second embodiment, FIG. 9 is a flowchart showing the content of the subject characteristic measurement process executed by the information processing apparatus 300 of the second embodiment, and FIG. 10 is an explanatory diagram showing an example of a state in which characteristic information CHI indicating the result of the subject characteristic measurement process in the second embodiment is displayed on the display unit 352. Hereinafter, among the configuration of the information processing apparatus 300 and the content of the subject characteristic measurement process in the second embodiment, those that are the same as those in the first embodiment described above will be given the same reference numerals, and the description thereof will be omitted as appropriate.

[0068] In the subject characteristic measurement process in the first embodiment described above, the speed selection instruction acquisition unit 317 of the information processing apparatus 300 acquires the speed selection instruction VI after the execution of the speed fixed display process P1 and before the execution of the speed variable display process P2. On the other hand, in the subject characteristic measurement process in the second embodiment, the speed selection instruction acquisition unit 317 acquires the speed selection instruction VI during the speed variable display process P2. That is, when the subject EX wants to decrease the traveling speed of the vehicle during the speed variable display process P2, the subject EX is instructed to perform a touch operation on the deceleration button BB (FIG. 8) displayed on the display unit 352 as a speed selection instruction VI for decreasing the traveling speed (hereinafter also referred to as "deceleration instruction").

[0069] Also, in the subject characteristic measurement process in the second embodiment, among the characteristics of the subject EX, the risk when the subject EX drives a vehicle and moves on a road is measured.

[0070] In the subject characteristic measurement process in the second embodiment shown in FIG. 9, the processes from S110 to S130 (processes related to the speed fixed display process P1) in the subject characteristic measurement process in the first embodiment shown in FIG. 3 are similarly executed.

[0071] After the completion of the speed fixed display process P1, the display control unit 312 of the information processing apparatus 300 starts the speed variable display process P2 (S142). In the speed variable display process P2, the display control unit 312 causes the simulated driving image SI to be displayed in such a manner that the traveling speed V is set according to the speed selection instruction VI by the subject EX. That is, the speed selection instruction acquisition unit 317 monitors whether a deceleration instruction (a touch operation on the deceleration button BB displayed on the display unit 352) by the subject EX is received during the speed variable display process P2. When such a deceleration instruction is received, the display control unit 312 switches the simulated driving image SI displayed on the display unit 352 to a simulated driving image SI that simulates the view from the driver's seat of a vehicle whose traveling speed has decreased from the reference speed V1. Note that the traveling speed of the vehicle in the simulated driving image SI may be changeable in two steps (the reference speed V1 and the low speed (V1 - ΔV)), or may be changeable in three or more steps or steplessly (continuously).

[0072] When the variable speed display process P2 starts, similar to during the above-described fixed speed display process P1, the position specification acquisition unit 316 of the information processing apparatus 300 starts accepting a position specification for designating a specific position in the simulated driving image SI by the subject EX, and starts recording position specification information LDI indicating the history of the position specification (S152). Also, at this time, the speed selection instruction acquisition unit 317 of the information processing apparatus 300 starts accepting a deceleration instruction by the subject EX, and starts recording speed selection instruction information VII indicating the history of the deceleration instruction. The speed selection instruction information VII is information indicating the time (time on the simulated driving image SI) when the subject EX gave a deceleration instruction. By referring to the speed selection instruction information VII, it is possible to grasp in which scene of the simulated driving image SI the subject EX felt a risk sufficient to require deceleration. The acquired and updated position specification information LDI and speed selection instruction information VII are stored in the storage unit 330.

[0073] The display control unit 312 of the information processing apparatus 300 monitors whether the variable speed display process P2 has been completed (S160). If it is determined that the variable speed display process P2 has been completed (S160: YES), the process proceeds to S172.

[0074] When the fixed speed display process P1 and the variable speed display process P2 are completed, the characteristic measurement unit 318 of the information processing apparatus 300 refers to the correct answer information RAI stored in advance in the storage unit 330, and the position specification information LDI and the speed selection instruction information VII created and updated during the execution of the fixed speed display process P1 and the variable speed display process P2, and starts measuring the risk as one of the characteristics during driving for the subject EX as described in detail below.

[0075] First, the characteristic measurement unit 318 of the information processing apparatus 300 selects one hazard Hn in the simulated operation image SI (S172), and with reference to the correct answer information RAI and the position designation information LDI, during the speed-fixed display process P1, determines whether there is a position designation (a touch operation to the position where the hazard Hn is displayed on the display unit 352) for correctly designating the position of the hazard Hn by the subject EX at a specific timing when a scene including the selected hazard Hn is displayed (S174). This determination is made by specifying the display timing of the scene including the selected hazard Hn (the display time of the frame including the hazard Hn) and the position of the hazard Hn (the coordinates of the image area representing the hazard Hn on the frame) with reference to the correct answer information RAI, and determining whether a position designation for designating the position of the hazard Hn is made at this display timing with reference to the position designation information LDI. In S174, if it is determined that there is a position designation for correctly designating the position of the hazard Hn during the speed-fixed display process P1 (S174: YES), the characteristic measurement unit 318 determines that the subject EX was able to correctly recognize the hazard Hn (hereinafter, this case is referred to as "hazard recognition case C0"), does not execute the risk value addition process described later, and advances the process to S194. In the example of the characteristic measurement result shown in FIG. 10, for each of the hazards H1, H3, H6, and H8, since the subject EX was able to correctly recognize the hazard during the speed-fixed display process P1 (correct position designation: 〇), the risk value is not added (in FIG. 10, the symbol "-" is shown in the risk value column).

[0076] On the other hand, in S174, when it is determined that there is no position specification for correctly specifying the position of the hazard Hn during the speed-fixed display process P1 (S174: NO), the characteristic measurement unit 318 of the information processing apparatus 300 refers to the correct answer information RAI and the position specification information LDI, and during the speed-variable display process P2, determines whether there is a position specification for correctly specifying the position of the selected hazard Hn by the subject EX at a specific timing when the scene including the hazard Hn is displayed (S176). In S176, when it is determined that there is no position specification for correctly specifying the position of the hazard Hn during the speed-variable display process P2 (S176: NO), that is, when the subject EX cannot correctly recognize the hazard Hn during both the speed-fixed display process P1 and the speed-variable display process P2, the characteristic measurement unit 318 refers to the speed selection instruction information VII, and during the speed-variable display process P2, determines whether there is a deceleration instruction (a touch operation on the deceleration button BB displayed on the display unit 352) by the subject EX at the timing when the scene including the hazard Hn is displayed (S182).

[0077] In S182, when it is determined that there is a deceleration instruction by the subject EX at a specific timing when the scene including the hazard Hn is displayed during the speed-variable display process P2 (S182: YES), the characteristic measurement unit 318 of the information processing apparatus 300 determines that although the subject EX cannot correctly recognize the hazard Hn during both the speed-fixed display process P1 and the speed-variable display process P2, the subject recognized (meta-cognized) the lack of his / her own recognition ability and gave a deceleration instruction (hereinafter, this case is referred to as "hazard non-recognition - deceleration present case C3"), and adds the third risk value Rv3 (for example, Rv3 = 0.7) (S188). In the example of the characteristic measurement result shown in FIG. 10, for each of the hazards H7 and H10, although the subject EX cannot correctly recognize the hazard during both the speed-fixed display process P1 and the speed-variable display process P2 (correct position specification: ×), since a deceleration instruction was given in the scene including the hazard during the speed-variable display process P2 (deceleration instruction: 〇), the third risk value Rv3 (for example, Rv3 = 0.7) associated with the hazard non-recognition - deceleration present case C3 is added.

[0078] On the other hand, in S182, when it is determined that there is no deceleration instruction by the subject EX at a specific timing when a scene including the hazard Hn is displayed during the variable speed display process P2 (S182: NO), the characteristic measurement unit 318 of the information processing apparatus 300 determines that the subject EX cannot correctly recognize the hazard Hn during both the fixed speed display process P1 and the variable speed display process P2, and does not recognize (meta-cognize) the lack of their own recognition ability, so no deceleration instruction is given either. (Hereinafter, this case is referred to as "hazard unrecognized - no deceleration case C4"). Then, a fourth risk value Rv4 (for example, Rv4 = 1.0) is added (S192). The fourth risk value Rv4 associated with this hazard unrecognized - no deceleration case C4 is set to a value larger than the third risk value Rv3 associated with the above-described hazard unrecognized - deceleration case C3. In the example of the characteristic measurement result shown in FIG. 10, for the hazard H9, the subject EX cannot correctly recognize the hazard during both the fixed speed display process P1 and the variable speed display process P2 (correct position designation: ×), and no deceleration instruction is given in the scene including the hazard during the variable speed display process P2 (deceleration instruction: ×), so the fourth risk value Rv4 (for example, Rv4 = 1.0) associated with the hazard unrecognized - no deceleration case C4 is added.

[0079] Also, in S176, when it is determined that there is a correct position designation for designating the position of the hazard Hn by the subject EX during the variable speed display process P2 (S176: YES), that is, when the subject EX could not correctly recognize the hazard Hn during the fixed speed display process P1 but could correctly recognize the hazard Hn during the variable speed display process P2, the characteristic measurement unit 318 refers to the speed selection instruction information VII and determines whether there is a deceleration instruction by the subject EX at a specific timing when the scene including the hazard Hn is displayed during the variable speed display process P2 (S178).

[0080] In S178, when it is determined that there has been a deceleration instruction by the subject EX at a specific timing when a scene including a hazard Hn is displayed during the variable speed display process P2 (S178: YES), the characteristic measurement unit 318 of the information processing apparatus 300 determines that the subject EX could correctly recognize the hazard Hn that could not be correctly recognized during the fixed speed display process P1 during the variable speed display process P2, and recognized (meta-cognized) the lack of his or her own recognition ability and gave a deceleration instruction (hereinafter, this case is referred to as "hazard quasi-recognition - deceleration present case C1"), and adds the first risk value Rv1 (for example, Rv1 = 0.3) (S184). In the example of the characteristic measurement result shown in FIG. 10, for each of the hazards H2 and H4, although the subject EX could not correctly recognize the hazard during the fixed speed display process P1 (correct position designation: ×), the subject could correctly recognize the hazard during the variable speed display process P2 (correct position designation: 〇), and since a deceleration instruction was given in the scene including the hazard during the variable speed display process P2 (deceleration instruction: 〇), the first risk value Rv1 (for example, Rv1 = 0.3) associated with the hazard quasi-recognition - deceleration present case C1 is added.

[0081] On the other hand, in S178, when it is determined that the subject EX did not give a deceleration instruction at a specific timing when a scene including a hazard Hn was displayed during the variable-speed display process P2 (S178: NO), the characteristic measurement unit 318 of the information processing apparatus 300 determines that the subject EX could correctly recognize the hazard Hn that could not be correctly recognized during the fixed-speed display process P1 during the variable-speed display process P2, but did not give a deceleration instruction because the subject did not recognize (meta-cognize) the lack of their own recognition ability (hereinafter, this case is referred to as "hazard quasi-recognition - no deceleration case C2"). Then, a second risk value Rv2 (for example, Rv2 = 0.5) is added (S186). The second risk value Rv2 associated with this hazard quasi-recognition - no deceleration case C2 is set to a value larger than the third risk value Rv3 associated with the above-described hazard non-recognition - deceleration case C3, although it is smaller than the first risk value Rv1 associated with the hazard quasi-recognition - deceleration case C1. In the example of the characteristic measurement results shown in FIG. 10, for hazard H5, although the subject EX could not correctly recognize the hazard during the fixed-speed display process P1 (correct position designation: ×), the subject could correctly recognize the hazard during the variable-speed display process P2 (correct position designation: 〇), but no deceleration instruction was given in the scene including the hazard during the variable-speed display process P2 (deceleration instruction: ×). Therefore, the second risk value Rv2 (for example, Rv2 = 0.5) associated with the hazard quasi-recognition - no deceleration case C2 is added.

[0082] For one selected hazard Hn, when the above-described processes of S174 to S192 are completed, the characteristic measurement unit 318 determines whether all the hazards Hn included in the simulated driving image SI have been selected (S194). If it is determined that there is an unselected hazard Hn (S194: NO), the process returns to the selection process of hazard Hn (S172), and the subsequent processes are performed in the same manner. In the example of the evaluation results shown in FIG. 10, since there are 10 hazards Hn, the above-described processes of S174 to S192 are repeatedly executed for each hazard Hn until it is determined that the selection of the 10 hazards Hn is completed.

[0083] Such processing is repeated, and when it is determined in S194 that the selection of all hazards Hn is completed (S194: YES), the characteristic measurement unit 318 creates characteristic information CHI representing the result of the characteristic measurement (for example, the total score of the risk values), and outputs the characteristic information CHI (S212). For example, as shown in FIG. 10, the characteristic measurement unit 318 displays the content of the characteristic information CHI on the display unit 352. As described above, the subject characteristic measurement process for evaluating the risk when the subject EX drives a vehicle and moves on the road is completed.

[0084] In the example of the characteristic measurement result shown in FIG. 10, for four hazards (hazards H1, H3, H6, H8), the risk values are not added assuming that they are hazard recognition cases C0, and for two hazards (hazards H2, H4), the first risk value Rv1 (for example, Rv1 = 0.3) is added assuming that they are hazard semi-recognition - deceleration present cases C1, for one hazard (hazard H5), the second risk value Rv2 (for example, Rv2 = 0.5) is added assuming that it is a hazard semi-recognition - no deceleration case C2, for two hazards (hazards H7, H10), the third risk value Rv3 (for example, Rv3 = 0.7) is added assuming that they are hazard non-recognition - deceleration present cases C3, and for one hazard (hazard H9), the fourth risk value Rv4 (for example, Rv4 = 1.0) is added assuming that it is a hazard non-recognition - no deceleration case C4, and the total of the risk values is, for example, 3.5 points (the maximum value of the risk values is, for example, 10 points). It can be said that the higher the risk value, the higher the risk when the subject EX drives a vehicle and moves on the road.

[0085] B-2. Effects of the Second Embodiment: As described above, in the information processing apparatus 300 of the second embodiment, similar to the information processing apparatus 300 of the first embodiment, the display control unit 312 executes a variable-speed display process P2 for displaying the simulated driving image SI in such a manner that the driving speed is set according to the speed selection instruction VI acquired by the speed selection instruction acquisition unit 317. The characteristic measurement unit 318 measures the characteristics of the subject EX based on the content of the speed selection instruction VI (the presence or absence of a speed selection instruction VI for reducing the driving speed) in addition to the pointing result correlated with whether there is a correct position specification of the position of the hazard Hn at a specific timing when a scene including each hazard Hn of the simulated driving image SI during the variable-speed display process P2 is displayed. Therefore, according to the information processing apparatus 300 of the second embodiment, it is possible to measure the characteristics of the subject EX based on the action of selecting the driving speed of the automobile by oneself, and the appropriateness of the characteristic measurement of the subject EX can be improved.

[0086] Also, in the information processing apparatus 300 of the second embodiment, similar to the information processing apparatus 300 of the first embodiment, the display control unit 312 further executes a speed-fixed display process P1 for displaying the simulated driving image SI on the display unit 352 in a manner where the driving speed is fixed to a reference speed V1 set in advance. The characteristic measurement unit 318 measures the characteristics of the subject EX based on the pointing result in the speed-fixed display process P1 in addition to the pointing result in the variable-speed display process P2 and the content of the speed selection instruction VI. Therefore, according to the information processing apparatus 300 of the second embodiment, it is possible to measure the characteristics of the subject EX by comparing the pointing results in each of the speed-fixed display process P1 in which the driving speed is fixed to the reference speed V1 and the variable-speed display process P2 in which the subject EX can select the driving speed, and the appropriateness of the characteristic measurement of the subject EX can be effectively improved.

[0087] Also, in the information processing apparatus 300 of the second embodiment, the speed selection instruction acquisition unit 317 acquires a speed selection instruction VI during the variable speed display process P2, and the display control unit 312 changes the traveling speed according to the speed selection instruction VI during the variable speed display process P2. Therefore, according to the information processing apparatus 300 of the second embodiment, it is possible to measure the characteristics of the subject EX based on an action closer to an actual driving environment, that is, changing (decelerating) the traveling speed during the driving of the automobile, and effectively improve the appropriateness of the measurement of the characteristics of the subject EX.

[0088] In the information processing apparatus 300 of the second embodiment, the characteristics of the subject EX include the risk during the movement of the subject EX. When there is no position designation that correctly designates the position of the hazard Hn at the specific timing during the variable speed display process P2, the characteristic measurement unit 318 determines that the risk is lower when there is a deceleration instruction than when there is no deceleration instruction. When the hazard Hn cannot be recognized at the specific timing during the variable speed display process P2, if there is a deceleration instruction, it is considered that a compensatory action has been taken because the subject is meta-aware of the lack of their own recognition ability. On the other hand, if there is no deceleration instruction, it is considered that no compensatory action has been taken because the subject is not meta-aware of the lack of their own recognition ability. According to the information processing apparatus 300 of the second embodiment, when such a compensatory action is taken, it is determined that the risk is lower compared to the case where no compensatory action is taken, so the appropriateness of risk measurement as a characteristic of the subject EX can be improved.

[0089] Also, in the information processing apparatus 300 of the second embodiment, when there is no position designation that correctly designates the position of the hazard Hn at the specific timing during the speed-fixed display process P1, and there is no position designation that correctly designates the position of the hazard Hn at the specific timing during the variable-speed display process P2, the characteristic measurement unit 318 determines that the risk is lower when there is a deceleration instruction during the variable-speed display process P2 than when there is no deceleration instruction. When the hazard Hn cannot be recognized during both the speed-fixed display process P1 and the variable-speed display process P2, if there is a deceleration instruction, it is considered that a compensatory action has been taken because the subject is meta-aware of the lack of their own recognition ability. On the other hand, if there is no deceleration instruction, it is considered that no compensatory action has been taken because the subject is not meta-aware of the lack of their own recognition ability. According to the information processing apparatus 300 of the second embodiment, when such a compensatory action is taken, it is determined that the risk is lower compared to the case where no compensatory action is taken, so the appropriateness of risk measurement as a characteristic of the subject EX can be improved.

[0090] Also, in the information processing apparatus 300 of the second embodiment, when there is no position designation that correctly designates the position of the hazard Hn at the specific timing during the speed-fixed display process P1, and there is a position designation that correctly designates the position of the hazard Hn at the specific timing during the variable-speed display process P2, the characteristic measurement unit 318 determines that the risk is lower when there is a deceleration instruction during the variable-speed display process P2 than when there is no deceleration instruction. Even if the hazard Hn can be recognized during the variable-speed display process P2, when the hazard Hn cannot be recognized during the speed-fixed display process P1, if there is a deceleration instruction, it is considered that a compensatory action has been taken because the subject is meta-aware of the lack of their own recognition ability. On the other hand, if there is no deceleration instruction, it is considered that no compensatory action has been taken because the subject is not meta-aware of the lack of their own recognition ability. According to the information processing apparatus 300 of the second embodiment, when such a compensatory action is taken, it is determined that the risk is lower compared to the case where no compensatory action is taken, so the appropriateness of risk measurement as a characteristic of the subject EX can be improved.

[0091] Also, in the information processing apparatus 300 of the present embodiment, the display control unit 312 executes the variable speed display process P2 after executing the fixed speed display process P1. Therefore, according to the information processing apparatus 300 of the present embodiment, for a scene including a hazard Hn that could not be recognized in the fixed speed display process P1, the level of metacognitive ability can be accurately grasped based on the presence or absence of a deceleration instruction in the subsequent variable speed display process P2, and the appropriateness of measurement as a characteristic of the subject EX can be effectively improved.

[0092] C. Third Embodiment: FIG. 11 is a flowchart showing the content of the subject characteristic measurement process in the third embodiment. FIG. 12 is an explanatory diagram showing an example of a state in which characteristic information CHI showing the result of the subject characteristic measurement process in the third embodiment is displayed on the display unit 352. The configuration of the information processing apparatus 300 in the third embodiment is the same as the configuration of the information processing apparatus 300 in the second embodiment described above. Hereinafter, among the processing contents of the subject characteristic measurement process in the third embodiment, the same processing contents as those in the second embodiment described above will be denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

[0093] In the subject characteristic measurement process in the second embodiment described above, as the display (reproduction) process of the simulated driving image SI, two processes, namely, the fixed speed display process P1 and the variable speed display process P2, are executed. However, in the subject characteristic measurement process in the third embodiment, only the variable speed display process P2 is executed, and the fixed speed display process P1 is not executed. That is, in the subject characteristic measurement process in the third embodiment shown in FIG. 11, the processes from S110 to S130 (processes related to the fixed speed display process P1) in the subject characteristic measurement process in the second embodiment shown in FIG. 9 are not executed, and the process starts from the process of S142. Further, in the subject characteristic measurement process in the third embodiment, in the characteristic (risk) measurement process after S172, the process of S174 (determination process of the presence or absence of hazard recognition during the fixed speed display process P1) shown in FIG. 9 is not executed, and the process of S176 is immediately executed.

[0094] Also, in the subject characteristic measurement process in the third embodiment, when it is determined that there is no position specification for correctly specifying the position of the hazard Hn during the variable speed display process P2 (S176: NO), the process is the same as the subject characteristic measurement process in the second embodiment. That is, when it is determined in S176 that there is no position specification for correctly specifying the position of the hazard Hn during the variable speed display process P2 (S176: NO), the characteristic measurement unit 318 determines whether there is a deceleration instruction from the subject EX at the timing when the scene including the hazard Hn is displayed (S182). When it is determined that there is a deceleration instruction (S182: YES), the third risk value Rv3 (for example, Rv3 = 0.7) is added (S188). When it is determined that there is no deceleration instruction (S182: NO), the fourth risk value Rv4 (for example, Rv4 = 1.0) is added (S192). In the example of the characteristic measurement result shown in FIG. 12, for each of the hazards H7 and H10, although the subject EX could not correctly recognize the hazard during the variable speed display process P2 (correct position specification: ×), since a deceleration instruction was given in the scene including the hazard (deceleration instruction: 〇), the third risk value Rv3 (for example, Rv3 = 0.7) is added. For the hazard H9, since the subject EX could not correctly recognize the hazard during the variable speed display process P2 (correct position specification: ×) and no deceleration instruction was given in the scene including the hazard (deceleration instruction: ×), the fourth risk value Rv4 (for example, Rv4 = 1.0) is added.

[0095] On the other hand, in the subject characteristic measurement process in the third embodiment, the process when it is determined that there is a position specification that correctly specifies the position of the hazard Hn during the variable speed display process P2 (S176: YES) is different from the subject characteristic measurement process in the second embodiment. That is, in this case, the characteristic measurement unit 318 determines whether there is a deceleration instruction by the subject EX at the timing when the scene including the hazard Hn is displayed (S178). Then, when it is determined that there is a deceleration instruction (S178: YES), the characteristic measurement unit 318 determines that the subject EX has decelerated the vehicle, does not execute the risk value addition process, and advances the process to S194. In the example of the characteristic measurement result shown in FIG. 12, for each of the hazards H1, H3, H5, H6, and H8, the subject EX gave a deceleration instruction (deceleration instruction: ○) during the variable speed display process P2, and since the hazard was correctly recognized (correct position specification: ○), the risk value was not added.

[0096] On the other hand, when the characteristic measurement unit 318 determines that there is no deceleration instruction (S178: NO), it determines that the hazard was correctly recognized but the subject EX did not give a deceleration instruction, and adds a first risk value Rv1 (for example, Rv1 = 0.3) that is smaller than the above-described third risk value Rv3 and fourth risk value Rv4 (S184). In the example of the characteristic measurement result shown in FIG. 12, for each of the hazards H2 and H4, the subject EX could correctly recognize the hazard during the variable speed display process P2 (correct position specification: ○), but did not give a deceleration instruction (deceleration instruction: ×), so the first risk value Rv1 (for example, Rv1 = 0.3) was added. The subsequent processing is the same as that in the second embodiment.

[0097] As described above, also in the information processing apparatus 300 of the third embodiment, the display control unit 312 executes a variable-speed display process P2 for displaying the simulated driving image SI in such a manner that the traveling speed is set according to the speed selection instruction VI acquired by the speed selection instruction acquisition unit 317. The characteristic measurement unit 318 measures the characteristics of the subject EX based on the content of the speed selection instruction VI, in addition to the pointing result correlated with whether or not there is a position designation that correctly designates the position of the hazard Hn at a specific timing when a scene including the hazard Hn of the simulated driving image SI during the variable-speed display process P2 is displayed. Therefore, according to the information processing apparatus 300 of the third embodiment, similar to the information processing apparatus 300 of the second embodiment, it is possible to measure the characteristics of the subject EX based on the action of self-selecting the traveling speed of the automobile, and it is possible to improve the appropriateness of the characteristic measurement of the subject EX.

[0098] D. Fourth Embodiment: D-1. Configuration of the Information Processing System 10: FIG. 13 is an explanatory diagram showing a schematic configuration of the information processing system 10 in the fourth embodiment, and FIG. 14 is a block diagram showing a schematic configuration of the information processing system 10 in the fourth embodiment. Hereinafter, among the configurations of the fourth embodiment, the same configurations as those of the above-described second embodiment will be denoted by the same reference numerals, and the description thereof will be appropriately omitted.

[0099] The information processing system 10 of the fourth embodiment is a system that measures the characteristics of the subject EX when the subject EX drives an automobile and moves on a road. More specifically, the information processing system 10 visually presents a simulated driving image SI (right-eye image SIr and left-eye image SIl) that simulates the field of vision of a human driving an automobile and moving on a preset course to the subject EX, and conducts a hazard recognition test to determine whether the subject EX recognizes each hazard included in the simulated driving image SI. Based on the results of the hazard recognition test, it is a system that measures the characteristics of the subject EX when the subject EX drives an automobile and moves on a road. As shown in FIGS. 13 and 14, the information processing system 10 includes an information processing device 100 and a head-mounted display (hereinafter referred to as "HMD") 200 as an image display device.

[0100] (Configuration of the information processing device 100) As shown in FIGS. 13 and 14, in this embodiment, a personal computer (hereinafter referred to as "PC") is used as the information processing device 100. The information processing device 100 includes a control unit 110, a storage unit 130, a display unit 152, an operation input unit 158, and an interface unit 159. These units are connected to each other via a bus 190 so as to be communicable with each other.

[0101] The display unit 152 of the information processing device 100 is configured by, for example, a liquid crystal display or an organic EL display, and displays various images and information. Also, the operation input unit 158 of the information processing device 100 is configured by, for example, a keyboard, a mouse, a microphone, etc., and receives operations and instructions from the administrator or the subject EX. Further, the interface unit 159 of the information processing device 100 is configured by, for example, a LAN interface or a USB interface, etc., and communicates with other devices by wire or wirelessly. In this embodiment, the interface unit 159 of the information processing device 100 is connected to the interface unit 259 (described later) of the HMD 200 via a cable 12 and communicates with the interface unit 259 of the HMD 200.

[0102] The storage unit 130 of the information processing apparatus 100 is constituted by, for example, a ROM, a RAM, a hard disk drive (HDD), etc., and stores various programs and data, and is also used as a work area or a temporary storage area for data when executing various programs. For example, the storage unit 130 stores a characteristic measurement program CP, which is a computer program for executing the risk assessment process during driving described later.

[0103] In addition, the storage unit 130 of the information processing apparatus 100 stores moving image data MID. In the present embodiment, as will be described later, in order to change the simulated driving image SI that is visually recognized by the subject EX according to the movement of the head of the subject EX, the moving image data MID includes data of a plurality of simulated driving images SI corresponding to each orientation of the head of the subject EX. Further, in the present embodiment, since the simulated driving image SI to be visually recognized by the subject EX is a 3D image, the simulated driving image SI is composed of a right-eye image SIr and a left-eye image SIl created in consideration of parallax. The moving image data MID representing the simulated driving image SI may be created by, for example, 3D-CG software, or may be created using an image captured by an omnidirectional camera while driving a vehicle on a real road.

[0104] In addition, during the subject characteristic measurement process described later, viewpoint information VPI, response operation information ANI, speed selection instruction information VII, and characteristic information CHI are stored in the storage unit 130 of the information processing apparatus 100. The contents of these pieces of information will be described in accordance with the description of the subject characteristic measurement process described later.

[0105] The control unit 110 of the information processing apparatus 100 is constituted by, for example, a CPU or the like, and controls the operation of the information processing apparatus 100 by executing a computer program read from the storage unit 130. For example, the control unit 110 executes the subject characteristic measurement process described later by reading and executing the characteristic measurement program CP from the storage unit 130. More specifically, the control unit 110 functions as a head information acquisition unit 111, a display control unit 112, a viewpoint information acquisition unit 113, a response operation acquisition unit 116, a speed selection instruction acquisition unit 117, and a characteristic measurement unit 118 for executing the subject characteristic measurement process described later. The functions of these units will be described in accordance with the description of the subject characteristic measurement process described later.

[0106] (Configuration of HMD200) The HMD200 as an image display device is a device that allows a subject EX to visually recognize an image while being worn on the head of the subject EX. The HMD200 of the present embodiment is a non-transmissive head-mounted display that completely covers both eyes of the subject EX and can provide a virtual reality (VR) function. In this specification, the fact that the HMD200 allows the subject EX to visually recognize an image is also expressed as the HMD200 displays an image (to the subject EX). The HMD200 is an example of the image display unit in the claims.

[0107] The HMD200 includes a control unit 210, a storage unit 230, a right-eye display execution unit 251, a left-eye display execution unit 252, a gaze detection unit 253, headphones 254, a head movement detection unit 255, an operation input unit 258, and an interface unit 259. These units are connected to each other via a bus 290 so as to be communicable with each other.

[0108] The right-eye display execution unit 251 of the HMD 200 includes, for example, a light source, a display element (such as a digital micromirror device (DMD) or a liquid crystal panel), and an optical system. By generating image light representing the right-eye image SIr that constitutes the simulated driving image SI and guiding it to the right eye of the subject EX, the subject EX is made to visually recognize the right-eye image SIr with the right eye. The left-eye display execution unit 252 is provided independently of the right-eye display execution unit 251. Similar to the right-eye display execution unit 251, for example, it includes a light source, a display element, and an optical system. By generating image light representing the left-eye image SIl that constitutes the simulated driving image SI and guiding it to the left eye of the subject EX, the subject EX is made to visually recognize the left-eye image SIl with the left eye. In a state where the right eye of the subject EX visually recognizes the right-eye image SIr and the left eye of the subject EX visually recognizes the left-eye image SIl, the subject EX visually recognizes the simulated driving image SI which is a 3D image.

[0109] The gaze detection unit 253 of the HMD 200 detects the gaze direction of the subject EX in order to realize a so-called eye-tracking function. For example, the gaze detection unit 253 includes a light source that emits non-visible light and a camera. The light source emits non-visible light, and the non-visible light reflected by the eyes of the subject EX is imaged by the camera to generate an image. By analyzing the generated image, the gaze direction of the subject EX is detected. The gaze detection unit 253 repeatedly executes the detection of the gaze direction at a predetermined frequency (for example, the same frequency as the frame rate of the moving image displayed by the right-eye display execution unit 251 and the left-eye display execution unit 252). Note that by detecting the gaze direction of the subject EX, the gaze detection unit 253 can specify the position of the viewpoint VP (see FIG. 13) of the subject EX on the image that the subject EX is visually recognizing.

[0110] The headphones 254 of the HMD200 are devices that are worn on the ears of the subject EX and output sound. Also, the head movement detection unit 255 of the HMD200 is a sensor that detects the movement of the HMD200 (i.e., the movement of the head of the subject EX) in order to realize a so-called head tracking function. Note that the movement of the head of the subject EX is a concept that includes changes in the position and orientation of the head of the subject EX. Further, the operation input unit 258 of the HMD200 includes, for example, buttons and the like and receives instructions from the subject EX. Note that the operation input unit 258 may be disposed inside the housing of the HMD200 (the portion worn on the head of the subject EX), or may be configured as a separate body connected to the housing via a signal line. Also, the interface unit 259 of the HMD200 is configured by, for example, a LAN interface, a USB interface, or the like, and communicates with other devices by wire or wirelessly.

[0111] The storage unit 230 of the HMD200 is configured by, for example, a ROM, a RAM, or the like, and stores various programs and data, or is used as a work area or a temporary storage area for data when executing various programs. Also, the control unit 210 of the HMD200 is configured by, for example, a CPU or the like, and controls the operations of each part of the HMD200 by executing a computer program read from the storage unit 230.

[0112] D-2. Subject characteristic measurement process: Next, the subject characteristic measurement process executed by the information processing system 10 of the fourth embodiment will be described. FIG. 15 is a flowchart showing the content of the subject characteristic measurement process in the fourth embodiment. FIGS. 16 and 17 are explanatory diagrams schematically showing the state of the subject EX and the simulated driving image SI visually recognized by the subject EX during the subject characteristic measurement process in the fourth embodiment. FIG. 18 is an explanatory diagram showing an example of a state in which the characteristic information CHI indicating the result of the subject characteristic measurement process in the fourth embodiment is displayed on the display unit 152.

[0113] In the subject characteristic measurement process of the fourth embodiment, a hazard recognition test is performed in the same manner as in the subject characteristic measurement process of the second embodiment. However, in this embodiment, during the hazard recognition test, when the subject EX recognizes what he / she considers to be a hazard Hn, the subject EX is instructed to give an answer by operating the operation input unit 158 (for example, a left click operation of the mouse). Also, similar to the second embodiment, during the variable speed display process P2, when the subject EX wants to decrease the driving speed of the vehicle, the subject EX is instructed to perform an operation (for example, a right click operation of the mouse) of the operation input unit 158 as a speed selection instruction VI (deceleration instruction) to decrease the driving speed.

[0114] The subject characteristic measurement process is started, for example, when the administrator inputs an instruction to start the process via the operation input unit 158 of the information processing apparatus 100 while the subject EX is wearing the HMD 200. When the subject characteristic measurement process is started, a fixed speed display process P1 is started in the same manner as in the subject characteristic measurement process of the second embodiment (S110). However, in the fourth embodiment, since the HMD 200 is used, the display control unit 112 of the information processing apparatus 100 starts displaying the simulated driving image SI on the HMD 200. Specifically, the display control unit 112 supplies the moving image data MID stored in the storage unit 130 to the HMD 200, and causes the right-eye display execution unit 251 and the left-eye display execution unit 252 of the HMD 200 to display the right-eye image SIr and the left-eye image SIl that constitute the simulated driving image SI, respectively.

[0115] Note that the information processing system 10 of the present embodiment has a so-called head tracking function, and changes the simulated driving image SI to be visually recognized by the subject EX according to the movement of the subject EX's head. That is, the head information acquisition unit 111 of the information processing device 100 acquires head information for specifying the movement of the head of the subject EX detected by the head movement detection unit 255 of the HMD 200 from the HMD 200, and the display control unit 112 of the information processing device 100, according to the movement of the head of the subject EX specified by the acquired head information, selects the moving image data MID supplied to the right-eye display execution unit 251 and the left-eye display execution unit 252 of the HMD 200. Thereby, the subject EX visually recognizes the simulated driving image SI that naturally changes according to the movement of his / her own head. For example, as shown in column A of FIG. 16, when the subject EX is facing forward and viewing an image of a certain scene, and then, as shown in column B of FIG. 16, when the subject EX changes the direction of his / her head to the left, the image visually recognized by the subject EX naturally changes from the above scene to an image of a scene shifted to the left. Thereby, the subject EX is placed in an environment that is extremely close to the actual driving environment in terms of vision. Note that the selection of the moving image data MID supplied to the right-eye display execution unit 251 and the left-eye display execution unit 252 may be executed by the control unit 210 of the HMD 200.

[0116] Simultaneously with the start of the speed fixed display process P1, the viewpoint information acquisition unit 113 of the information processing device 100 starts a process of acquiring from the HMD 200 viewpoint information VPI for specifying the position of the viewpoint VP of the subject EX on the simulated driving image SI specified by the gaze detection unit 253 of the HMD 200 (S122). Also, at the same time, the response operation acquisition unit 116 of the information processing device 100 starts accepting a response operation (operation of the operation input unit 158) by the subject EX and starts recording response operation information ANI indicating the history of the operation. The acquired / updated viewpoint information VPI and response operation information ANI are stored in the storage unit 130.

[0117] The viewpoint information VPI is information that specifies the position (coordinates) of the viewpoint VP of the subject EX at each time of the simulated driving image SI. By referring to the viewpoint information VPI, it is possible to grasp where the subject EX is fixating in each scene of the simulated driving image SI. Also, the response operation information ANI is information that specifies the time (time in the simulated driving image SI) when a response was made by the subject EX. By referring to the response operation information ANI, it is possible to grasp at which time (i.e., in which scene) in the simulated driving image SI the subject EX recognized what they considered to be a hazard Hn. Therefore, by referring to the viewpoint information VPI and the response operation information ANI, it is possible to grasp in which scene in the simulated driving image SI and at which position the subject EX recognized something as a hazard Hn. Thus, the viewpoint information acquisition unit 113 and the response operation acquisition unit 116 function as a position designation acquisition unit that receives a position designation for designating a specific position in the simulated driving image SI by the subject EX.

[0118] Note that in FIGS. 13, 16, 17, etc., for convenience of explanation, a mark indicating the viewpoint VP is drawn superimposed on the simulated driving image SI. However, in the present embodiment, actually, the mark indicating the viewpoint VP is not displayed as an image, and the subject EX during the test is not made to be aware of the position of their own viewpoint VP. However, it may be configured such that the mark indicating the viewpoint VP is displayed (visible to the subject EX).

[0119] The display control unit 112 of the information processing apparatus 100 monitors whether or not the speed-fixed display process P1 has been completed (S130). If it is determined that the speed-fixed display process P1 has been completed (S130: YES), the process proceeds to S142. In S142, similar to the subject characteristic measurement process of the second embodiment, the variable-speed display process P2 is started. In the variable-speed display process P2, similar to the subject characteristic measurement process of the second embodiment, the display control unit 112 causes the simulated driving image SI to be displayed in such a manner that the driving speed decreases from the reference speed V1 to the low speed (V1 - ΔV) in response to the deceleration instruction received from the subject EX by the speed selection instruction acquisition unit 117. However, in the fourth embodiment, similar to the speed-fixed display process P1, the display control unit 112 supplies the moving image data MID to the HMD 200, and causes the right-eye display execution unit 251 and the left-eye display execution unit 252 of the HMD 200 to display the right-eye image SIr and the left-eye image SIl that constitute the simulated driving image SI, respectively.

[0120] When the variable-speed display process P2 is started, similar to during the above-described speed-fixed display process P1, the recording of the viewpoint information VPI and the response operation information ANI is started (S154). At this time, in addition, the speed selection instruction acquisition unit 117 starts accepting the deceleration instruction from the subject EX, and starts recording the speed selection instruction information VII indicating the history of the deceleration instruction. The acquired / updated viewpoint information VPI, response operation information ANI, and speed selection instruction information VII are stored in the storage unit 130.

[0121] The display control unit 112 of the information processing apparatus 100 monitors whether or not the variable-speed display process P2 has been completed (S160). If it is determined that the variable-speed display process P2 has been completed (S160: YES), the process proceeds to S172.

[0122] When the fixed-speed display process P1 and the variable-speed display process P2 are completed, in the same manner as the subject characteristic measurement process of the second embodiment, the characteristic measurement unit 118 of the information processing apparatus 100 starts measuring the characteristics of the subject EX during driving (S172 to S194). However, in the fourth embodiment, a determination as to whether the subject EX correctly recognized each hazard Hn during the fixed-speed display process P1 and the variable-speed display process P2 (a process corresponding to the processes of S174 and S176 in FIG. 9 in the second embodiment) is performed using the viewpoint information VPI and the response operation information ANI.

[0123] That is, the characteristic measurement unit 118 refers to the correct answer information RAI and the response operation information ANI to determine whether there was a response operation by the subject EX at a specific timing when a scene including the hazard Hn was displayed (S175, S177), and refers to the correct answer information RAI and the viewpoint information VPI to determine whether the position of the hazard Hn matches the position of the viewpoint VP of the subject EX at the timing when the scene including the hazard Hn was displayed (S181, S179). When it is determined that there was a response operation by the subject EX (S175, S177: YES) and the position of the viewpoint VP of the subject EX matches the position of the hazard Hn (S181, S179: YES), it is determined that the subject EX correctly recognized the hazard Hn, and in other cases, it is determined that the subject EX did not correctly recognize the hazard Hn.

[0124] For example, in the example of the characteristic measurement results shown in FIG. 18, for each scene including each of the hazards H1, H3, H6, H8 during the speed-fixed display process P1, there was a response from the subject EX (response operation: ○), and since the position of the hazard Hn and the position of the viewpoint VP of the subject EX coincided (position coincidence: ○), it was determined that the subject EX could correctly recognize the hazard (correct position designation: ○). On the other hand, for each scene including each of the hazards H2, H5, H7, H9, H10 during the speed-fixed display process P1, since there was no response from the subject EX (response operation: ×), it was determined that the subject EX could not correctly recognize the hazard (correct position designation: ×). Also, for the scene including the hazard H4 during the speed-fixed display process P1, although there was a response from the subject EX (response operation: ○), since the position of the hazard Hn and the position of the viewpoint VP of the subject EX did not coincide (position coincidence: ×), it was determined that the subject EX could not correctly recognize the hazard (correct position designation: ×).

[0125] Note that in this specification, the coincidence of the position of the hazard Hn and the position of the viewpoint VP of the subject EX means that the degree of coincidence of their positions is equal to or greater than a predetermined threshold. That is, the characteristic measurement unit 118 determines that the position of the hazard Hn and the position of the viewpoint VP of the subject EX coincide when the ratio of the length of time during which the position of the viewpoint VP of the subject EX coincides with the position (area) of the hazard Hn to the length of time during which the scene including the hazard Hn is displayed (i.e., the degree of coincidence of the position of the hazard Hn and the position of the viewpoint VP of the subject EX) is equal to or greater than a predetermined threshold. In column A of FIG. 17, an example where the position of the hazard Hn and the position of the viewpoint VP of the subject EX coincide is shown, and in column B of FIG. 17, an example where the position of the hazard Hn and the position of the viewpoint VP of the subject EX do not coincide is shown.

[0126] When the processing for all hazards Hn (S172 to S194) is completed (S194: YES), the characteristic measurement unit 118 creates characteristic information CHI representing the result of the characteristic measurement and outputs the characteristic information CHI (S212). For example, as shown in FIG. 18, the characteristic measurement unit 118 displays the content of the characteristic information CHI on the display unit 152. As described above, the subject characteristic measurement process for measuring the characteristics of the subject EX when the subject EX drives an automobile and moves on the road is completed.

[0127] As described above, also in the information processing system 10 of the fourth embodiment, the display control unit 112 executes the variable speed display process P2 for displaying the simulated driving image SI in such a manner that the traveling speed is set according to the speed selection instruction VI (deceleration instruction) by the speed selection instruction acquisition unit 117, and the characteristic measurement unit 118 determines whether there is a position designation that correctly designates the position of the hazard Hn at a specific timing when a scene including the hazard Hn of the simulated driving image SI during the variable speed display process P2 is displayed, and measures the characteristics of the subject EX based on the content of the speed selection instruction VI. Therefore, according to the information processing system 10 of the fourth embodiment, similar to the information processing apparatus 300 of the second embodiment, it is possible to measure the characteristics of the subject EX based on the action of selecting the traveling speed of the automobile by oneself, and it is possible to improve the appropriateness of the characteristic measurement of the subject EX.

[0128] E. Modification example: The technology disclosed in this specification is not limited to the above-described embodiments, and can be modified into various forms without departing from the gist thereof. For example, the following modifications are also possible.

[0129] The configurations of the information processing apparatus 300 or the information processing system 10 in each of the above embodiments are merely examples and can be variously modified. For example, in the first to third embodiments above, a tablet-type terminal is used as the information processing apparatus 300, but other types of computers (e.g., smartphones, PCs, etc.) may be used as the information processing apparatus 300. Also, in the fourth embodiment above, a PC is used as the information processing apparatus 100 constituting the information processing system 10, but other types of computers (e.g., smartphones, tablet terminals, etc.) may be used as the information processing apparatus 100. Further, in the fourth embodiment above, the HMD 200 is used as the image display device constituting the information processing system 10, but other types of image display devices (e.g., liquid crystal displays, projectors, etc.) may be used as the image display device. Note that when a device other than the HMD 200 (an image display device not worn on the head) is used as the image display device, sensors for detecting the viewing direction of the subject EX and sensors for detecting the movement of the head of the subject EX may be used separately from the image display device to detect the viewing direction of the subject EX and the movement of the head of the subject EX. Also, in the fourth embodiment, the information processing apparatus 100 and the image processing apparatus constituting the information processing system 10 may be an integrated device. For example, the information processing system 10 may be configured from an HMD 200 having the functions of the information processing apparatus 100 in the above embodiment.

[0130] Also, the content of the subject characteristic measurement process in each of the above embodiments is merely an example and can be variously modified. For example, in the second embodiment above, the speed selection instruction VI (deceleration instruction) for reducing the traveling speed by the subject EX is realized by a predetermined operation by the operation input unit 158 or a touch operation on the deceleration button BB displayed on the display unit 352, but the deceleration instruction may be realized by other means (e.g., operation of a device such as a pedal, voice operation, gesture operation, etc.).

[0131] Also, in the above first embodiment, the options for the traveling speed in the variable speed display process P2 include speeds higher than the reference speed V1, which is the traveling speed in the fixed speed display process P1, the same speed as the reference speed V1, and speeds lower than the reference speed V1. However, these options may not include at least one of them. Further, in the above second embodiment, in the variable speed display process P2, only the speed selection instruction VI (deceleration instruction) for decreasing the traveling speed from the reference speed V1 is possible. However, a speed selection instruction VI (acceleration instruction) for increasing the traveling speed from the reference speed V1 may also be executable. Further, in the above embodiment, a scene including a speed limit sign is provided in the simulated driving image SI. Even if the subject EX recognizes (touches the sign on the screen) the speed limit sign, when a speed selection instruction VI for selecting a speed exceeding the speed indicated by the sign is executed, in addition to a high risk-taking tendency, it may be determined that the attitude towards compliance with laws and regulations is low. Further, in the above embodiment, when outputting the characteristic information CHI indicating the characteristics of the subject EX, an explanation of the importance of selecting a speed according to the situation, future advice according to age-related changes, etc. may be provided. Further, in the above embodiment, the characteristic measurement results of the subject may be accumulated, and a determination and feedback regarding comparison with past results (for example, display of a message such as "The pointing rate was high last year even without reducing the speed, but this time the pointing rate has decreased compared to last year, so it is recommended to reduce the speed.") may be executed. Further, in the above embodiment, the past characteristic measurement results of a large number of subjects may be accumulated, and a relative evaluation of the characteristic measurement results of the current subject (for example, the positioning of the current subject relative to the average of all subjects) may be output.

[0132] In addition, the stages and criteria set for each characteristic (hazard perception ability, self-evaluation ability, self-control ability, and risk-taking tendency) of the subject EX in the above first embodiment are merely examples and can be variously changed. Further, in the above first embodiment, as characteristics of the subject EX, hazard perception ability, self-evaluation ability, self-control ability, and risk-taking tendency are used. However, as characteristics of the subject EX, at least one of these may not be used, or other characteristics may be used in addition to these characteristics.

[0133] In the above first embodiment, a self-evaluation SE of the pointing rate by the subject EX is obtained for the speed-fixed display process P1, and the self-evaluation SE is used for measuring the characteristics of the subject EX. However, instead of the speed-fixed display process P1, or together with the speed-fixed display process P1, a self-evaluation SE of the pointing rate by the subject EX may be obtained for the variable-speed display process P2, and the self-evaluation SE may be used for measuring the characteristics of the subject EX.

[0134] In addition, in the subject characteristic measurement process in the above fourth embodiment, in the hazard recognition test, when the subject EX recognizes each hazard Hn included in the simulated driving image SI, an answer is given by operating the operation input unit 158. However, the method of answering is not limited to operating the operation input unit 158, and other methods may be used. For example, when the ratio of the length of time during which the position of the viewpoint VP of the subject EX coincides with the position (area) of the hazard Hn to the length of time during which the scene including the hazard Hn is displayed (that is, the degree of coincidence between the position of the hazard Hn and the position of the viewpoint VP of the subject EX) is equal to or greater than a predetermined threshold value, it may be determined that the subject EX has recognized the hazard Hn even without operating the operation input unit 158.

[0135] Also, in the above-described first, second, and fourth embodiments, the variable-speed display process P2 is performed after the fixed-speed display process P1. Conversely, the fixed-speed display process P1 may be performed after the variable-speed display process P2. Further, in the above-described fourth embodiment, the fixed-speed display process P1 and the variable-speed display process P2 are executed. However, similar to the above-described third embodiment, only the variable-speed display process P2 may be executed. Also, in each of the above embodiments, the hazard recognition test may be repeatedly executed until the subject EX satisfies a predetermined criterion (for example, until the pointing rate becomes equal to or higher than a predetermined threshold). Also, in each of the above embodiments, instead of the pointing rate or the like, the score of the hazard recognition test may be used. Note that the score of the hazard recognition test is calculated, for example, by using the speed selected by the speed selection instruction VI in addition to the pointing rate and by using a function thereof (for example, addition or multiplication of the pointing rate and the speed).

[0136] Also, in the subject characteristic measurement process in each of the above embodiments, the simulated driving image SI includes a scene including the hazard Hn, and the characteristics of the subject EX during driving are measured by determining whether the subject EX correctly recognizes each hazard Hn. However, the target object to be recognized by the subject EX is not limited to the hazard Hn, and may be something that is not a hazard but affects the characteristics of the subject EX during driving, such as a signal or a road sign. Also, the target object may be something that predicts future changes, such as the blue blinking of a pedestrian signal. That is, in the subject characteristic measurement process in each of the above embodiments, a target object recognition test for determining whether such a target object can be recognized may be executed, and the target object perception ability as a characteristic of the subject EX may be measured based on the result of the test.

[0137] In addition, in each of the above embodiments, the simulated operation image SI includes a target representing an apparent risk and a target representing a potential risk. The characteristic measurement unit may evaluate the risk caused by the visual field defect based on the pointing result at a specific timing when a scene including the target representing the apparent risk is displayed, and evaluate the risk caused by the cognitive function decline based on the pointing result at a specific timing when a scene including the target representing the potential risk is displayed. In this way, the appropriateness of the evaluation of the risk caused by the visual field defect and the appropriateness of the evaluation of the risk caused by the cognitive function decline can be improved.

[0138] In addition, in each of the above embodiments, the characteristic information CHI is output by being displayed on the display units 152 and 352. However, the output form of the characteristic information CHI may be other forms, such as output by voice or printing using a printing device. Further, in the above embodiments, the content of the output characteristic information CHI is merely an example and can be variously modified. For example, the result of the pointing rate may be included in the characteristic information CHI, or the content indicating the appropriateness of the recognition for each hazard Hn may not be included, and only the total value of the final risk values (for example, 3.5 / 10 points) may be included.

[0139] In addition, in each of the above embodiments, the characteristics of the subject EX are measured when the subject EX drives an automobile and moves on the road. However, the technology disclosed in this specification can be similarly applied to the measurement of the characteristics of the subject EX when the subject EX moves by other means (for example, drives other types of vehicles (such as bicycles) or walks).

[0140] In addition, in each of the above embodiments, a part of the configuration realized by hardware may be replaced with software, and conversely, a part of the configuration realized by software may be replaced with hardware.
