Japanese Patent Publication No.57-4341 JP-A-5-317296

  In general, when a subject alternately presses down a plurality of operated parts, if the form (dimensional shape) or arrangement interval of the operated parts is different, the ease of pressing operation (difficulty) is different, and the diagnosis results are greatly different. The possibility to do. For this reason, when the to-be-operated part of a form and an arrangement | positioning space | interval differs, the diagnostic result cannot be compared and evaluated.

  Therefore, an object of the present invention is to provide a driving aptitude diagnosis device capable of appropriately comparing and evaluating the diagnosis results even when the form and arrangement interval of the operated parts to be used are different. .

  In order to solve the above problems, a driving suitability diagnosis apparatus of the present invention comprises display means, input means, display control means, determination time detection means, operation time detection means, storage means, correction means, calculation means, and output means. .

  The input means has a plurality of operated parts arranged in a straight line at equal intervals, and each operated part receives a pressing operation from the subject. The display control means causes the display means to display the determination time measurement image and the operation time measurement image. The determination time detection means detects the determination time of the subject by detecting a pressing operation on the operated part from the subject with respect to the display of the determination time measurement image. The operation time detecting means detects the operation time of the subject by detecting a pressing operation on the operated part from the subject performed according to the display of the operation time measurement image. The storage means stores a correspondence relationship between the shape characteristic of the input means and the action response reference time that is uniquely determined from the form of the operated part and the arrangement interval of the operated parts. The correction means obtains the motion response reference time corresponding to the shape characteristic of the input means and the motion response reference time corresponding to the predetermined reference shape characteristic using the correspondence read from the storage means, The difference between the motion response reference times is calculated as a correction time, and the determination time detected by the determination time detection unit and the operation time detected by the operation time detection unit are corrected using the calculated correction time. The calculation means calculates the driving suitability evaluation value according to a preset arithmetic expression using the determination time and the operation time corrected by the correction means. The output means outputs the driving suitability evaluation value calculated by the calculating means.

  In the above configuration, the storage means stores the correspondence between the shape characteristic of the input means uniquely determined from the configuration of the operated part and the arrangement interval of the operated parts and the operation response reference time, and the correcting means stores the storage means Using the correspondence relationship read out from, the motion response reference time corresponding to the shape characteristic of the input means and the motion response reference time corresponding to the predetermined reference shape property are obtained, and the difference between the obtained two motion response reference times Is calculated as the correction time, the determination time detected by the determination time detection means and the operation time detected by the operation time detection means are corrected using the calculated correction time, and the calculation means corrects the determination time corrected by the correction means. And the driving suitability evaluation value is calculated according to a preset arithmetic expression using the operation time.

  In other words, the calculation means always calculates the driving suitability evaluation value corrected so as to be evaluated in the same manner as when the operated part having the reference shape characteristic is used as a result of the driving suitability diagnosis. Therefore, even if the form and arrangement interval of the operated parts to be used are different, the diagnosis results can be appropriately compared and evaluated.

  According to this invention, even if it is a case where the form and arrangement | positioning space | interval of the to-be-operated part used differ, the diagnostic result can be compared and evaluated appropriately.

  As shown in FIGS. 2 to 7, on the upper surface of the input device 4, three input buttons 7 (7 a, 7 b, 7 c) as input units pressed by the subject are arranged in a straight line at equal intervals. In one input device 4, the operated portions 13 to 17 of the three input buttons 7a, 7b, and 7c have the same size and shape. Note that the subject who receives the driving aptitude diagnosis is informed beforehand that the three input buttons 7 correspond to the symbols “◯”, “Δ”, and “□”.

  As the input button 7 of the input device 4, in addition to the round buttons shown in FIGS. 2 and 3, for example, various types as shown in FIGS. 4 to 7 can be used.

  In the round buttons shown in FIGS. 2 and 3, the operated portions 13 of the input buttons 7 a, 7 b, 7 c have a circular shape in plan view, and a predetermined distance (hereinafter referred to as “the center of gravity” between adjacent operated portions 13). , Referred to as the inter-button distance). The inter-button distance L is set to be larger than twice the radius r of the operated portion 13 (L> 2r), and the outer edges of the adjacent operated portions 13 are separated from each other.

  The input button 7 shown in FIGS. 4 to 6 is a square button having different shapes of the operated parts 14, 15, and 16. The input button 7 shown in FIG. 7 is a piano in which the operated parts 17 are close to each other. Button. In the following description, the direction of the input buttons 7a, 7b, and 7c is the horizontal direction, the direction orthogonal to the direction of the input buttons 7a, 7b, and 7c is the vertical direction, and the operated portions 14 to 14 along the horizontal direction. A width of 17 is referred to as a horizontal width, and a width of each of the operated parts 14 to 17 along the vertical direction is referred to as a vertical width.

The operated portion 14 of the input button 7 shown in FIG. 4 has a hexagonal shape in plan view. The inter-button distance L is set to be larger than twice the radius (circumference of the circumscribed circle) r ₂ having a diameter equal to the width of the operated portion 14 (L> 2r ₂ ), and the outer edge of the adjacent operated portion 14. They are separated from each other.

The operated portion 15 of the input button 7 shown in FIG. 5 has a horizontally long rectangular shape in plan view with a horizontal width longer than the vertical width. The inter-button distance L is set to be larger than twice the radius r ₂ of a circle whose diameter is the width of the operated portion 15 (L> 2r ₂ ), and the outer edges of the adjacent operated portions 15 are separated from each other.

The operated portion 16 of the input button 7 shown in FIG. 6 has a square shape in plan view in which two pairs of diagonals face in the horizontal direction and the vertical direction. The inter-button distance L is set to be larger than twice the radius r ₂ of a circle whose diameter is the width of the operated portion 16 (L> 2r ₂ ), and the outer edges of the adjacent operated portions 16 are separated from each other.

The operated portion 17 of the input button 7 shown in FIG. 7 has a vertically long rectangular shape in plan view with a vertical width longer than a horizontal width. Button distance L is substantially equal to twice the radius r ₂ of a circle the width and the diameter of the operating unit 17, the operated portion 15 edge and adjacent are close.

  Which type of input button 7 is set as the standard type is not limited to the round type button, and is arbitrary, and how to set the size and shape of the standard type input button 7 is also arbitrary. It is.

  In addition, in the various types of input buttons 7 described above, if the distance L between the buttons is too short, the subject places a finger with one hand on the plurality of input buttons 7 and presses the input button 7 without moving the hand. There is a possibility that Such a pressing operation is too simple to make a difference in reaction time difficult to appear. For this reason, the inter-button distance L is preferably set to be at least half (for example, 100 mm or more) of the maximum distance from the thumb to the little finger when a relatively large hand is spread.

  The diagnosis execution processing device 2 includes an input / output unit 8, a control unit 9, and a storage unit 10. The input / output unit 8, the control unit 9, and the storage unit 10 are connected via a bus 11. The input / output unit 8 functions as an output unit, and the control unit 9 functions as a display control unit, a determination time detection unit, an operation time detection unit, a correction unit, and a calculation unit. The diagnosis execution processing device 2 may be a dedicated device or a general-purpose personal computer.

  The input / output unit 8 is an interface and transmits / receives data to / from the display device 3, the input device 4, and the printing device 5. In addition, a keyboard (not shown) is connected to the input / output unit 8, and various control signals and various data are diagnosed from the input / output unit 8 by the person performing the aptitude diagnosis and the subject performing input operations on the keyboard. Input to the processing device 2.

  The storage unit 10 includes a ROM (Read Only Memory) and a RAM (Random Access Memory), and stores various programs and various data for the control unit 9 to execute various processes. The various programs include a driving aptitude diagnosis program for the controller 9 to execute the driving aptitude diagnosis process. The driving aptitude diagnosis program includes a judgment time measurement data storage table and an operation time measurement used in the driving aptitude diagnosis process. A data storage table, a judgment time integration storage area, an operation time integration storage area, and a correction data storage area are included. The driving aptitude diagnosis program and each storage table may be read from an external storage medium such as various CD media (Compact Disc Media) and stored in the storage unit 10 or obtained via a network such as the Internet. It may be stored in the storage unit 10.

  In the correction data storage area, the measurement result when the driving aptitude diagnosis test is executed using the input button 7 other than the standard type can be evaluated in the same manner as when the input button 7 of the standard type is used. The correction data is stored in advance.

  In general, if the type and size of the input button 7 are different, the ease (difficulty) of repeatedly pressing a plurality of input buttons 7 is different. If the type and dimensions are different, the measurement results may be greatly different. In order to eliminate such an inconvenience, the correspondence relationship between the shape characteristic C of the input button 7 and the operation response reference time t is stored in advance as correction data in the correction data storage area.

The shape characteristic C of the input button 7 is a parameter representing the difficulty of operability due to the form (dimensional shape) and the arrangement interval (inter-button distance L) of the operated parts 13 to 17. For example, when a plurality of input buttons 7 are repeatedly pressed, the hit point converges to the center of gravity O of the operated parts 13 to 17. For this reason, regardless of the shapes of the operated parts 13 to 17, the effective operation range of the input button 7 is set inside a circle defined by a predetermined radius (hereinafter referred to as a button effective radius r) with the center of gravity O as the center. Can be considered. In the present embodiment, the radius r ₁ of the inscribed circle of the operated parts 13 to 17 centered on the center of gravity O is used as the button effective radius r. Since the pressing operation of the input button 7 tends to be difficult as the effective operation range is narrow, and tends to become difficult as the inter-button distance L is long, in this embodiment, the shape characteristic C of the input button 7 is shown. The ratio (r ₁ / L) between the inter-button distance L and the button effective radius r (inscribed circle radius r ₁ ) is used.

Since the maximum value of the radius r ₁ of the inscribed circle of the operated parts 13 to 17 is ½ of the inter-button distance L, the range of the shape characteristic C exceeds 0 (0%) to 0.5 ( 50%) or less. The smaller the shape characteristic C, the more difficult the pressing operation of the input button 7 is.

  If the correspondence relationship between the shape characteristic C stored in the correction data storage area and the motion response reference time t is such that the motion response reference time t is uniquely determined according to the shape characteristic C, an arithmetic expression or a table is used. Or a map. In the present embodiment, the following expression (1) is stored as an arithmetic expression indicating the relationship between the shape characteristic C and the motion response reference time t.

y = αx ² + βx + γ (1)
In the above equation, y is the value of the motion response reference time t (sec), x is the value of the shape characteristic C, and α, β, and γ are predetermined coefficients.

For the values of α, β and γ, for example, a plurality of input devices 4 having different shape characteristics C are used, and each input device 4 autonomously presses two predetermined input buttons 7 alternately as quickly as possible. The average time required to press the two input buttons 7 is measured in advance as the motion response reference time t, and as shown in FIG. 8, the shape characteristic C is the vertical axis (x axis) and the motion response reference time t is the horizontal axis (y axis). Each measured value is plotted in the coordinates defined as), and an approximate curve (secondary curve) thereof is determined. Note that in one input device 4, two adjacent input buttons 7 (e.g., an input button 7a input button 7b) as an input button 7 (input button 7a of the shape characteristics C ₁ and ends when using input buttons 7c ) from the shape characteristics C ₂ when using, C 1 _{= 2} × C _2, and the order they are different, to measure the dynamic response reference time t for two shape property C vary from one input device 4 Is possible. In the measurement for obtaining the relationship between the shape characteristic C and the operation response reference time t, the number of the practitioners may be one or plural.

In the example of FIG. 8, the values of α, β, and γ are α = + 0.6375, β = −0.5658, and γ = + 0.2649. In this case, the motion response reference time t with respect to the shape factor C = 0.2 (20%) is calculated as 0.177 sec, and the motion response reference time t with respect to the shape factor C = 0.5 (50%) is 0. It is calculated as 141 sec. Assuming that the shape factor C _{0 of the} standard type input button 7 is 0.2, it is measured when a driving aptitude diagnosis test described later is performed using the input button 7 having a shape factor C of 0.5. The operation time and the reaction time are faster by 0.177−0.141 = 0.036 sec than when the same subject uses the standard type input button 7. That is, the diagnostic result when the driving suitability diagnostic test is performed using the input button 7 having the shape factor C of 0.5 is obtained by adding 0.036 sec to the measured operation time and reaction time, respectively. Evaluation using the standard type can be performed in the same manner as the diagnostic result of the driving aptitude diagnostic test.

  In addition, the arithmetic expression which shows the relationship between the shape characteristic C and the operation | movement reaction reference time t is not limited to said (1) Formula.

The effective radius r is not limited to the radius r ₁ of the inscribed circle of the operated parts 13 to 17. For example, as shown in FIG. 4, when the difference between the radius r ₁ of the inscribed circle of the operated portion 14 and the radius r _{2 of} the circle whose diameter is the width of the operated portion 14 is relatively small, As shown, the radius r ₁ is the same when the difference between the radius r ₁ of the inscribed circle of the operated portion 15 and the radius r _{2 of} the circle whose diameter is the width of the operated portion 15 is relatively large. also, it radius r ₂ is greater (better shown in FIG. 5) is smaller (the one shown in FIG. 4) effective operation range is enlarged than. For this reason, the effective radius r may be calculated based on the radius r ₁ of the inscribed circle of the operated portion 15 and the radius r _{2 of} a circle whose diameter is the lateral width of the operated portion 15. Specifically, the effective radius r may be calculated according to r = m × r ₁ + n × r ₂ (m + n = 1, m and n are predetermined positive coefficients).

  The control unit 9 is configured by a CPU (Central Processing Unit), reads a driving aptitude diagnosis program from the storage unit 10, and executes driving aptitude diagnosis processing. The control unit 9 includes a timer 12 that can acquire a count value (for example, time) indicating a time for calculating a total measurement time and a unit measurement time described later. In addition, the control unit 9 transmits / receives various control signals, various data, and detection signals to / from the outside via the input / output unit 8, generates image data, and outputs the image data to the display device 3. Display the image. When the input button 7 is pressed, the detection signal is input to the control unit 9 via the input / output unit 8. Further, the control unit 9 can determine which of the three input buttons 7a, 7b, and 7c has been pressed.

[Overview of driving aptitude diagnostic test]
Next, an outline of the driving aptitude diagnosis test using the driving aptitude diagnosis apparatus 1 will be described.

  In this driving aptitude diagnosis test, the subject performs a predetermined number of times (three times in the present embodiment) a determination time measurement test and a predetermined number of times (two times in the present embodiment). The judgment time measurement test measures the total time (judgment time) of the subject's judgment + motion, and the motion time measurement test measures the time of the subject alone (motion time).

  In each determination time measurement test, after an image informing the start of the test is displayed on the display screen 6 of the display device 3, one symbol of “◯”, “Δ”, and “□” is displayed. (Measurement identification image) is sequentially displayed at random for a predetermined time (in this embodiment, 10 seconds), and an image for informing the end of the test is displayed after the predetermined time has elapsed. The subject visually recognizes the symbol displayed on the display screen 6 and inputs the input button 7 corresponding to the displayed symbol (for example, the input button 7a when the symbol is “◯”, and the input button 7a when the symbol is “△”). In the case of the input button 7b, “□”, the input button 7c) is pressed as soon as possible after the symbol is displayed. In this test, the time required from the display of the symbol until the input button 7 is pressed is sequentially measured and stored, and the average value is calculated as the determination time for one test. Then, the above test is performed three times, and finally the average value of the three tests is calculated as the determination time of the subject.

  In each operation time measurement test, an image for informing the start of the test is displayed on the display screen 6 of the display device 3, and an image for informing the end of the test after a predetermined time (in this embodiment, 10 seconds) is displayed. The In the meantime, the subject presses the two input buttons 7 (for example, the input button 7a and the input button 7c) autonomously and alternately as soon as possible regardless of the display on the display screen 6. In this test, the time required to press one input button 7 is sequentially measured and stored, and the average value is calculated as the operation time of one test. And the said test is performed twice and finally the average value of two tests is calculated as a test | inspection time of a test subject. In order to notify the subject that the input button 7 has been pressed, the display screen 6 has a predetermined symbol that moves up and down each time the input button 7 is pressed (for example, a star-shaped symbol (illustrated (Omitted)) is displayed.

[Driving aptitude diagnosis processing]
Next, driving aptitude diagnosis processing executed by the control unit 9 will be described.

  As shown in FIG. 3, the driving suitability diagnosis processing includes subject information acquisition processing (step S1), determination time calculation processing (step S2), operation time calculation processing (step S3), correction processing (step S4), and diagnosis result output. Including the process (step S5), the control unit 9 starts the process sequentially from the subject information acquisition process (step S1) when receiving a control signal instructing the start of the driving suitability diagnosis process from the keyboard.

[Subject information acquisition process]
In the subject information acquisition process, the control unit 9 causes the display screen 6 to display an image that requests the practitioner of the aptitude diagnosis and the subject to input various information. The various information includes the identification number or name, age, and sex of the subject. When the provider or subject of the aptitude diagnosis operates the keyboard according to the display on the display screen 6 and sequentially inputs various information (data), the input data is transmitted to the diagnosis execution processing device 2, and the control unit 9 receives the information. Data of various types of information is stored in the storage unit 10. When the input of all requested information is completed, the subject information acquisition process ends, and the process proceeds to a determination time calculation process.

[Judgment time calculation process]
When the process proceeds to the determination time calculation process, the control unit 9 causes the display screen 6 to display an image that prompts the subject of aptitude diagnosis to input a determination time measurement test start instruction. When the subject inputs a determination time measurement test start instruction by operating the keyboard according to the display on the display screen 6, a start instruction signal is transmitted to the diagnosis execution processing device 2, and the control unit 9 starts the determination time measurement test.

  When the determination time measurement test is started, the control unit 9 displays an image informing the start of the practice of the determination time measurement test on the display screen 6 and then executes the practice process. Since the practice process is the same as the contents of the test described later, the description thereof is omitted. However, the data acquired in practice is not used to calculate the average judgment time that will be the final diagnosis result.

  When the practice is finished, the control unit 9 displays an image on the display screen 6 asking whether it is possible to start the main test (actual). When the subject operates the keyboard to input a start instruction (start OK) for the main test, an instruction signal for starting the main test is transmitted to the diagnosis execution processing device 2, and the control unit 9 starts the main test. On the other hand, when the subject operates the keyboard to input the start rejection (start NO) of the test, an instruction signal for executing the practice again is transmitted to the diagnosis execution processing device 2, and the subject can practice again.

  When the main test is started, the control unit 9 displays an image informing the start of the main test and the number of the main test on the display screen 6 and acquires the count value of the timer 12 as the start of the main test. And stored in the storage unit 10.

  Subsequently, the control unit 9 randomly selects one symbol from the three types of symbols “◯”, “Δ”, and “□”, and displays an image of the selected symbol on the display screen 6 (stimulus display At the same time, the timer 12 starts measuring the total measurement time and the unit measurement time. If the previous unit time measurement reference time is already stored in the storage unit 10, the unit time measurement reference time acquired this time is updated. FIG. 2 shows an example in which the symbol “Δ” is selected and displayed.

  The subject visually recognizes the symbol displayed on the display screen 6 and presses the input button 7 corresponding to the displayed symbol as soon as possible after the symbol is displayed. When the input button 7 is pressed, the detection signal is transmitted from the input device 4 to the diagnosis execution processing device 2. When the input / output unit 8 receives the detection signal from the input device 4, the control unit 9 acquires the count value of the timer 12 as the current unit time measurement reference time, and reads the previous unit time measurement reference time from the storage unit 10. The time difference between the previous unit time measurement reference time and the current unit time measurement reference time is calculated as the unit measurement time, and the calculated unit measurement time is stored in the determination time measurement data storage table of the storage unit 10 and the storage unit The previous unit time measurement reference time stored in 10 is updated to the latest (current) unit time measurement reference time.

  Next, the control unit 9 acquires the count value of the timer 12, reads out the time when the main test starts from the storage unit 10, calculates the time difference between the acquired count value and the time when the main test starts as the total measurement time, It is determined whether or not the time has reached a predetermined time (10 seconds) (whether or not the predetermined time has passed since the start of the test). A symbol is selected at random, an image of the selected symbol is displayed on the display screen 6, and unit measurement times are sequentially calculated and stored each time the input button 7 is pressed. As described above, in the determination time measurement test, the time actually taken until the subject identifies the displayed symbol and performs the input operation is repeatedly measured and stored.

  When the total measurement time reaches a predetermined time (10 seconds), the first determination time measurement test ends, and the control unit 9 causes the display screen 6 to display an image for informing the end of the determination time measurement test. After the end of the first determination time measurement test, the second determination time measurement test and the third determination time measurement test are subsequently executed, and the determination time measurement process ends. As a result, the results of the three determination time measurement tests are stored in the determination time measurement data storage table.

  The control unit 9 calculates the average judgment time of one judgment time measurement test from the measurement results stored in the judgment time measurement data storage table, and the overall average judgment time used for diagnosis (hereinafter referred to as judgment time average value). (Referred to as T1) and is stored in the determination time measurement data storage table.

  Next, the control unit 9 determines the average judgment time of one judgment time measurement test from the measurement results stored in the judgment time measurement data storage table, and the overall average judgment time used for diagnosis (hereinafter referred to as judgment). (Referred to as a time average value T1) is calculated and stored in the determination time measurement data storage table, the determination time measurement process is terminated, and the process proceeds to the operation time measurement process.

[Operation time calculation process]
When the operation time calculation process is started, the control unit 9 causes the display screen 6 to display an image that prompts the subject of aptitude diagnosis to input an operation time measurement test start instruction. When the subject inputs an operation time measurement test start instruction by operating the keyboard according to the display on the display screen 6, a start instruction signal is transmitted to the diagnosis execution processing device 2, and the control unit 9 starts the operation time measurement test.

  When the operation time measurement test starts, the control unit 9 displays an image informing the start of the operation time measurement test practice on the display screen 6 and then executes the practice process. Since the practice process is the same as the contents of the test described later, the description thereof is omitted. However, data acquired in practice is not used to calculate the average operating time that will be the final diagnostic result.

  When the practice is finished, the control unit 9 displays an image on the display screen 6 asking whether it is possible to start the main test (actual). When the subject operates the keyboard to input a start instruction (start OK) for the main test, an instruction signal for starting the main test is transmitted to the diagnosis execution processing device 2, and the control unit 9 starts the main test. On the other hand, when the subject operates the keyboard to input the start rejection (start NO) of the test, an instruction signal for executing the practice again is transmitted to the diagnosis execution processing device 2, and the subject can practice again.

  When the main test is started, the control unit 9 displays an image for informing the start of the main test and the number of the main test on the display screen 6, and sets the count value of the timer 12 at the start of the main test and the unit. Obtained as time for time calculation and stored in the storage unit 10 individually.

  After the start of this test, the test subject autonomously presses the input button 7a and the input button 7c alternately as soon as possible regardless of the display on the display screen 6. When the input button 7 is pressed, the detection signal is transmitted from the input device 4 to the diagnosis execution processing device 2, and the control unit 9 acquires the count value of the timer 12 as the unit time measurement reference time and stores it in the storage unit 10. Remember. When the previous unit time measurement reference time is already stored in the storage unit 10, the unit time measurement reference time acquired this time is updated.

  Next, when the input button 7 is pressed, the detection signal is transmitted from the input device 4 to the diagnosis execution processing device 2, and the control unit 9 acquires the count value of the timer 12 as the current unit time measurement reference time. The previous unit time measurement reference time is read from the storage unit 10, the time difference between the previous unit time measurement reference time and the current unit time measurement reference time is calculated as the unit measurement time, and the calculated unit measurement time is stored in the storage unit 10 The previous unit time measurement reference time stored in the storage unit 10 is updated to the latest (current) unit time measurement reference time. During execution of the operating time measurement test, the control unit 9 informs the subject that the pressing operation of the input button 7 has been detected, so that the display screen 6 is moved up and down each time the input button 7 is pressed. A predetermined symbol (star symbol) to be moved is displayed.

  Next, the control unit 9 adds the number of executions (the number of times of pressing) in the number-of-executions storage area (area for accumulating the number of pressings) of the storage unit 10 once. In addition, the count value of the timer 12 is acquired, the start time of the main test is read from the storage unit 10, the time difference between the acquired count value and the start of the main test is calculated as the total measurement time, and the total measurement time is a predetermined time (10 Seconds) (whether or not a predetermined time has elapsed since the start of the test), and if the predetermined time has not elapsed, the input button 7 Unit measurement times are sequentially calculated and stored each time the button is pressed. As described above, in the operation time measurement test, the time for which the subject alternately performs the input operation on the input button 7 is repeatedly measured and stored.

  When the total measurement time reaches a predetermined time (10 seconds), the first operation time measurement test is ended, and the control unit 9 causes the display screen 6 to display an image for informing the end of the operation time measurement test. After the end of the first operation time measurement test, the second operation time measurement test is subsequently executed, and the operation time measurement process ends. As a result, the results of the two operation time measurement tests are stored in the operation time measurement data storage table.

  Next, the control unit 9 determines the average operation time of one operation time measurement test from the measurement results stored in the operation time measurement data storage table, and the total average operation time used for diagnosis (hereinafter referred to as operation). (Referred to as a time average value T2) and is stored in the operation time measurement data storage table, the operation time measurement process is terminated, and the process proceeds to the correction process.

[Correction process]
When the process proceeds to the correction process, as shown in FIG. 10, the control unit 9 acquires the inter-button distance L and the button effective radius r (the radius r ₁ of the inscribed circle of the operated units 13 to 17) (step S11). Then, the shape characteristic C is calculated (step S12). Note that the inter-button distance L and the button effective radius r are input by a driving aptitude diagnostic test provider or a subject, and stored in the storage unit 10, and the control unit 9 reads them from the storage unit 10. The input of the inter-button distance L and the button effective radius r by the provider or the like may be the start of execution of the correction process or before that (for example, when inputting subject information).

Next, the control unit 9, according to the above formula (1), and the dynamic response reference time t based on the calculated shape characteristics C in step S12, shape characteristics (reference shape characteristics) of standard type dynamic response reference time based on C ₀ calculating a t ₀ (step S13), and by subtracting the dynamic response reference time t from the dynamic response reference time _{t 0,} to calculate a correction time _{Δt (Δt = t 0 -t)} ( step S14).

For example, a driving aptitude diagnosis test is performed using a round button (shown in FIG. 3) in which the radius of the operated portion 13 (radius of the inscribed circle) r (r ₁ ) is 20 mm and the distance L between the buttons is 100 mm. In this case, the shape characteristic C is 0.2, and the motion response reference time t is calculated as 0.1772 sec according to the above formula (1). Assuming a round button (shown in FIG. 3) having a radius of the operated portion 13 (radius of the inscribed circle) r (r ₁ ) of 30 mm and a distance L between the buttons of 100 mm as a standard type, the shape characteristics of the standard type C ₀ is 0.3, and this shape characteristic C ₀ is stored in advance in the storage unit 10 as the reference shape characteristic, and the motion response reference time t ₀ corresponding to the reference shape characteristic C ₀ is 0 according to the above equation (1). Calculated as 1525 sec. This is because a test subject who can respond in 0.1525 sec when using the input button 7 of the standard type (shape characteristic C ₀ = 0.3) used the input button 7 having the shape characteristic C of 0.2. In this case, it means that the reaction is delayed by 0.1772 sec, and this difference (Δt = −0.1772 sec) is calculated as the correction time.

  Next, the control unit 9 converts the average judgment time and judgment time average value T1 stored in the judgment time measurement data storage table, and the average operation time and operation time average value T2 stored in the operation time measurement data storage table. On the other hand, the correction time Δt is added and stored in the determination time measurement data storage table and the operation time measurement data storage table, respectively, and the correction process is terminated (step S15), and the process proceeds to the diagnosis result output process.

[Diagnosis result output processing]
When shifting to the driving suitability evaluation value calculation process, the control unit 9 corrects the average judgment time and the judgment time average value T1 after correction stored in the judgment time measurement data storage table and the correction stored in the operation time measurement data storage table. The subsequent average operation time and the operation time average value T2 are read out, and the driving suitability evaluation value is calculated and stored in the storage unit 10 in accordance with the following arithmetic expression stored in advance.

Driving aptitude evaluation value = 3 / T1-1 / (T2 × 2)
When the driving aptitude evaluation value calculation process is completed, the process proceeds to a diagnosis result output process, and the control unit 9 generates image data for displaying the driving aptitude diagnosis result explanation sheet shown in FIG. 11 and inputs the generated image data. The data is output from the output unit 8 to the display device 3 and the printing device 5. As a result, the driving aptitude diagnosis result explanation sheet is displayed on the display screen 6 and is printed out on a predetermined sheet and provided to the subject. The image data of the driving aptitude diagnosis result commentary sheet includes image data (evaluation value data) representing the driving aptitude evaluation value, but the driving aptitude evaluation value is numerical data (evaluation value data) and the image data is You may make it output separately.

  The driving aptitude diagnosis result commentary sheet includes personal information 20 such as name, age, and gender input from the subject and the results of the judgment time measurement test (first to third average judgment time and overall average judgment time). (Judgment time average value T1)) 21, results of the operation time measurement test (first and second average operation time and overall average operation time (operation time average value T2)) 22, driving suitability evaluation value 23, The first driving aptitude evaluation graph 24 and the second driving aptitude evaluation graph 25 are displayed. A type display field 26 for displaying the type of the subject corresponding to the driving aptitude evaluation value 23 is provided below the driving aptitude evaluation value 23. Next to the first driving aptitude evaluation graph 24, the operation time is displayed. And a description column 27 such as an evaluation regarding the balance of judgment time and points to be noted on safe driving based on this evaluation, and next to the second driving aptitude evaluation graph 25 is a driving aptitude evaluation considering this age and this A description column 28 for points to be considered for safe driving based on the evaluation is provided.

  In the first driving aptitude evaluation graph 24, mainly the balance between the operation time and the judgment time and the diagnosis result of the driving aptitude evaluation value are visually displayed to the subject. In other words, the first driving aptitude evaluation graph 24 displays a diagnostic result display area that is partitioned by a vertical axis having the judgment time as a parameter and a horizontal axis orthogonal to the vertical axis using the operation time as a parameter. In this diagnostic result display area, the closer to the upper left part, the longer the judgment time and the shorter the operation time, the more the behavior tends to be sensual (lighter and a little bit). The closer to the lower part, the more the behavior tends to be logical (careful and tired). The tendency of each part is appropriately displayed in the diagnosis result display area.

  Further, a plurality of boundaries 31 to 38 and a diagnostic result display point 39 are displayed in the diagnostic result display area. Each of the boundaries 31 to 38 represents a driving aptitude evaluation value that serves as a threshold for determining aptitude for driving. Specifically, the boundary 31 is the judgment time and the operation time when the driving suitability evaluation value is 0.5, the boundary 32 is the judgment time and the operation time when the driving suitability evaluation value is 1.0, and the boundary 33 is the driving suitability. The judgment time and the operation time when the evaluation value is 1.5, the boundary 34 is the judgment time and the operation time when the driving suitability evaluation value is 2.0, and the boundary 35 is the judgment time when the driving suitability evaluation value is 2.5. The boundary 36 indicates the determination time and the operation time when the driving aptitude evaluation value is 3.0, the boundary 37 indicates the determination time and the operation time when the driving aptitude evaluation value is 3.5, and the boundary 38 indicates the driving aptitude. The judgment time and the operation time at which the evaluation value is 4.0 are continuous lines. And the subdivision area | region I above the boundary 31 is a type which drives by a can, and the subdivision area | region II between the boundary 31 and the boundary 32 is a type which relies too much on the senses, and between the boundary 32 and the boundary 33 The subdivision region III is a type that tends to depend on the senses, the subdivision region IV between the boundary 33 and the boundary 34 is the type in which the action precedes, and the subdivision region V between the boundary 34 and the boundary 35 is optimal ( The subdivision area VI between the boundary 35 and the boundary 36 is the optimum (thinking) type, and the subdivision area VII between the boundary 36 and the boundary 37 is a type in which thought comes first. The subdivision area VIII between the boundary 37 and the boundary 38 is a type that tends to rely on thinking, and the subdivision area IX below the boundary 38 is a type that relies too much on thinking. The above type for each subdivision area is appropriately displayed in the diagnosis result display area and its margin.

  The diagnosis result display point 39 is a point corresponding to the determination time average value T1 and the operation time average value T2. Accordingly, the subject can visually recognize the balance between his / her operation time and determination time by viewing the position of the diagnosis result display point 39 in the diagnosis result display area. Further, the subdivision area to which the diagnosis result display point 39 belongs can be visually recognized, and the self type can be easily understood.

  In the second driving aptitude evaluation graph 25, the driving aptitude evaluation in comparison with drivers of the same age group is visually displayed to the subject. That is, in the second driving aptitude evaluation graph 25, a diagnostic result display area is displayed that is partitioned by a vertical axis having the determination time as a parameter and a horizontal axis orthogonal to the vertical axis using the operation time as a parameter. In this diagnostic result display area, the closer to the upper left part, the longer the judgment time and the shorter the operation time, the more the behavior tends to be sensual (lighter and a little bit). Similar to the first driving aptitude evaluation graph 24, the closer to the lower part, the more the behavior tends to be logical (careful and tired).

  In addition, within the diagnostic result display area, age-specific standard ranges 41 to 46 and the diagnostic result display points 39 are displayed. Each age standard range 41 to 46 represents a range of standard determination time and operation time for drivers belonging to each age group. Specifically, the range 41 is teenage (under 20 years old), the range 42 is in the 20s (under 20 and under 30), the range 43 is in the 30s (under 30 and under 40), and the range 44 is in the 40s ( 40 years old and under 50 years old), range 45 is in the range of standard judgment time and operating time for drivers in their 50s (over 50 years old and under 60 years old), and range 46 is for those in their 60s and over (60 years old and over) is there. The standard range is, for example, an average value ± standard deviation of determination time and operation time in each age group.

  Accordingly, as in the case of the first driving aptitude evaluation graph 24, the subject visually recognizes the balance between his / her operation time and judgment time by looking at the position of the diagnosis result display point 39 in the diagnosis result display area. can do. Further, by comparing the diagnostic result display point 39 with the age-specific standard ranges 41 to 46 to which the own age belongs, it is possible to visually recognize the evaluation of driving aptitude in comparison with drivers of the same age group. it can. For example, when the diagnosis result display point 39 is not included in the age-specific standard ranges 41 to 46 to which the user's age belongs, the subject is earlier in the operation time and the determination time than the driver of the same age group, or It can be judged that it is slow. When the diagnosis result display points 39 are included in the age-specific standard ranges 41 to 46 to which the user's age belongs, the subject has the diagnosis result display points 39 in any part of the age-specific standard ranges 41 to 46. Depending on the position, it is possible to visually recognize the evaluation of the balance between the operation time and the judgment time in comparison with drivers of the same age group.

  As described above, according to the present embodiment, the driving suitability evaluation value corrected so as to be evaluated in the same manner as when the standard type operated part 13 having the reference shape characteristic is used is always calculated as a result of the driving suitability diagnosis. And provided to the subject. Therefore, even when the driving suitability diagnosis test is performed using the operated parts 13 to 17 having different forms and arrangement intervals, the diagnosis results can be appropriately compared and evaluated.

  Note that each time the driving suitability evaluation test is performed, the control unit 9 updates the correspondence relationship (calculation formula) between the shape characteristic C and the motion reaction reference time t and stores it in the correction data storage area (correspondence relationship). Update processing) may be executed.

  It is preferable to execute the correspondence update process before calculating the motion response reference time t in the correction process.

When the correspondence update process is started, the control unit 9 acquires the inter-button distance L and the button effective radius r (the radius r ₁ of the inscribed circle of the operated units 13 to 17), for example, as shown in FIG. Step S21), the shape characteristic C ₁ (C ₁ = r / L) when the two adjacent input buttons 7 are pressed, and the shape characteristic C ₂ (C ₂ = r / L) when the input buttons 7 at both ends are pressed. 2L) is calculated (step S22). When one or both of the shape characteristic C ₁ and the shape characteristic C ₂ are already calculated and stored in the storage unit 10, this process is omitted, and the shape characteristic C ₁ and the shape characteristic C ₂ are stored in the storage unit. Read from 10.

Next, the control unit 9 requests the subject to perform an input operation similar to the operation time measurement test. In accordance with this request, the test subject autonomously presses two adjacent input buttons 7 (for example, the input button 7a and the input button 7b) alternately as soon as possible, and then inputs the input buttons 7 (the input buttons 7a and the input buttons 7a). Buttons 7c) are alternately pressed as soon as possible autonomously. The control unit 9 executes the same process as in the operation time calculation process, and calculates the average operation time as the operation response reference times t ₁ and t ₂ (steps S23 and S24).

Next, the control unit 9 corrects the calculated values (C ₁ , t ₁ ) and (C ₂ , t ₂ ) as sample data for obtaining a correspondence relationship between the shape characteristic C and the operation reaction reference time t. The data is stored (registered) in the data storage area (step S25). When the operation time calculation process has already been executed and the average operation time when the input buttons 7 (input button 7a and input button 7c) at both ends are used is stored in the storage unit 10, the process proceeds to step S24. process is omitted, may be used an average operation time calculated in operation time calculation processing as an operation reaction reference time t _2. A plurality of sample data may be stored in advance in the correction data storage area as initial setting sample data.

  Next, the control unit 9 determines whether or not the number of sample data (the number of registrations) registered in the correction data storage area is equal to or greater than a predetermined number (for example, 20) (step S26). If the number is greater than or equal to the predetermined number (step S26: Yes), the correspondence relationship (calculation formula) between the shape characteristic C and the motion reaction reference time t is obtained based on the registered sample data, and the correspondence stored in the correction data storage area The relationship (calculation formula) is updated (step S27), and this process is terminated. Note that the initial setting sample data may or may not be included in the number of sample data.

  On the other hand, when the number of registrations is less than the predetermined number (step S26: No), this process is terminated without updating the correspondence relationship (calculation formula) between the shape characteristic C and the operation response reference time t. In this case, in the correction process, the correspondence relationship (calculation formula) that is set and stored in advance is used as it is.

  Thus, since the correspondence relationship (calculation formula) between the shape characteristic C and the motion reaction reference time t is updated every time the driving suitability evaluation test is performed, the reliability of the correspondence relationship between the two is improved. Therefore, even when the driving suitability diagnostic test is performed using the operated parts 13 to 17 having different forms and arrangement intervals, the diagnostic results can be compared and evaluated more appropriately.
