[0032] Hereinafter, embodiments relating to one aspect of the present invention will be described based on the drawings.

[0033] §1 Examples of Application <Information terminal 10 to which the present invention is applied> Figure 1 shows an example of an information terminal 10 equipped with the cognitive function testing device 1 of the present invention. The information terminal 10 includes a display screen 11 on which test information is displayed when performing a cognitive function test. The information terminal 10 is, for example, a smartphone or a tablet. The display screen 11 also functions as a touch panel on which test information can be entered. The information terminal 10 also includes a speaker (not shown) that outputs the test information as sound.

[0034] §2 Example Configuration <Hardware configuration of cognitive function testing device 1> Figure 2 shows an example of the hardware configuration of the cognitive function testing device 1. The hardware of the cognitive function testing device 1 can be realized, for example, by the information processing device 20 shown in Figure 2. The information processing device 20 comprises a processor 21, a memory 22, a communication interface 23, and a user interface 24. The processor 21, memory 22, communication interface 23, and user interface 24 are connected, for example, by a bus 25.

[0035] The processor 21 is a circuit that performs signal processing, and is, for example, a CPU (Central Processing Unit) that controls the entire information processing device 20. The processor 21 is an example of the control unit of the present invention. The processor 21 may be implemented using other digital circuits such as an FPGA (Field Programmable Gate Array) or a DSP (Digital Signal Processor). Furthermore, the processor 21 may be implemented by combining multiple digital circuits.

[0036] Memory 22 includes, for example, main memory and auxiliary memory. Main memory is, for example, RAM (Random Access Memory). Main memory is used as the work area of ​​processor 21.

[0037] Auxiliary memory is a non-volatile memory such as a magnetic disk, optical disk, or flash memory. Various programs for operating the information processing device 20 are stored in the auxiliary memory. The programs stored in the auxiliary memory are loaded into main memory and executed by the processor 21.

[0038] Furthermore, the auxiliary memory may include portable memory that can be removed from the information processing device 20. Portable memory may include memory cards such as USB (Universal Serial Bus) flash drives and SD (Secure Digital) memory cards, or external hard disk drives.

[0039] The communication interface 23 is a communication interface that performs network communication between the information processing device 20 and an external entity (for example, an external server). The communication interface 23 is controlled by the processor 21.

[0040] The user interface 24 includes, for example, an input device that receives operational input from a test-taker undergoing a cognitive function test, and an output device that outputs information to the test-taker. The input device can be implemented, for example, by a touch panel. The output device can be implemented, for example, by a display or a speaker. The user interface 24 is controlled by the processor 21.

[0041] For example, in a cognitive function test, the processor 21 performs an output process that outputs the "test words" to be memorized to the test-taker, an answer reception process that receives answers from the test-taker indicating whether or not the output is a test word, and a result output process that outputs the results of the cognitive function test. The processor 21 may also perform a training process, for example, between the output process and the answer reception process.

[0042] <Output Processing> The processor 21 plays multiple test words to the test taker via the display screen 11 and speaker of the information terminal 10. For example, the processor 21 sequentially displays the test words as images or text on the display screen 11, thereby allowing the test taker to memorize the displayed test words. Alternatively, the processor 21 may also output the test words as audio via the speaker of the information terminal 10 in combination with the image or text display. The played test words are stored in memory 22 as image information, audio information, and text information. The test words are examples of the first and second words.

[0043] <Answer submission processing> The processor 21 sequentially displays multiple "problem words" on the display screen 11, which consist of multiple test words output to the test-taker during the output process and multiple "non-test words" that are not included in those test words. In this case as well, the display of the problem words on the display screen 11 may be an image or a text. Alternatively, an audio output may be combined with the image or text display. In addition, along with the display of the problem words, the processor 21 also displays an "answer image" on the display screen 11 for the test-taker to answer whether or not the displayed problem word is a test word output during the output process. The processor 21 then accepts the answer to the displayed problem word based, for example, on the test-taker's selection of the answer image by touch operation.

[0044] When the processor 21 switches the question word displayed on the display screen 11 to another question word, it changes the display configuration of the answer image displayed together with the question word. For example, when the processor 21 switches question words, it changes the arrangement of the displayed answer images. Alternatively, when the processor 21 switches question words, it may change the spacing between the displayed answer images, change the display size of the answer images, change the display shape of the answer images, change the movement of the answer images, change the design of the answer images, or change the timing of the display of the answer images.

[0045] <Result Output Processing> The processor 21 displays the results of the correctness judgment for each question word received from the examinee during the answer reception process on the display screen 11. For example, the processor 21 displays the number of correct answers relative to the number of questions as the examinee's test score on the display screen 11.

[0046] §3 Example of Operation [Operation of cognitive function testing equipment] Next, with reference to Figures 3 to 19, we will explain examples of the operation of the cognitive function testing device 1 in cognitive function testing.

[0047] Figure 3 is a flowchart showing the overall processing procedure in a cognitive function test. As shown in Figure 3, the processor 21 of the cognitive function test device 1 performs the cognitive function test in the following order: output processing in step S11, training processing in step S12, answer reception processing in step S13, and result output processing in step S14. The cognitive function test is started by touch operation on the display screen 11 of the information terminal 10.

[0048] <Output processing in step S11> When output processing begins, the processor 21 makes an announcement, for example, "Now, please memorize the words displayed on the screen. There are 16 questions. Let's begin." Then, the processor 21 displays the test words 31 that the test taker is to memorize, one word at a time, on the display screen 11, for example, as shown in Figure 4. The test words 31 are displayed from question 1 to question 16. The display time for each test word can be set arbitrarily, but is set to approximately 5 seconds, for example. In the example shown in the figure, the test word 31 "moon" is displayed as text. The processor 21 also displays a question mark 41a on the display screen 11 to indicate that the current test process is the "output process" among the "output process," "training process," "answer process," and "result process." The processor 21 also displays a question number mark 42 on the display screen 11 to indicate that the current question is, for example, question 13 out of 16 questions, and an elapsed time bar 43 to indicate the elapsed time of the output process.

[0049] <Training process in step S12> Once the output processing in step S11 is complete, the processor 21 executes a training process that plays content different from the cognitive function test in order to load the test-taker's cognitive abilities. In other words, the training process is performed to train the test-taker, who has memorized the target words in the output processing, not to answer with the memorized words immediately, but to answer with them after a short delay.

[0050] When transitioning from output processing to training processing, the processor 21 displays a training mark 41b, as shown in Figure 5, to indicate that the current process is training, and also displays a comment 44 such as, "Now, let's train your brain with the time you have to answer." The training is configured so that the test-taker can arbitrarily select from, for example, training A, B, and C. The processor 21 displays selection buttons 45a to 45c for selecting the type of training.

[0051] <Step S13 Answer Reception Processing> When the training process in step S12 is completed, the processor 21 sequentially displays multiple words on the display screen 11 and executes an answer reception process in which the user answers whether the displayed words are the test words presented in the output process. For example, as shown in Figure 6, the processor 21 displays an answer mark 41c to indicate that the current process is the answer reception process, and also displays a comment 46 such as, "Now, please answer whether the words you memorized were there." This starts the answer reception process.

[0052] Figure 7 shows an example of a question image for one question that is displayed on the display screen 11 when answering each question. As shown in Figure 7, the processor 21 sequentially displays question words 47 on the display screen 11, which the user is asked to answer whether they were present in the test words. Question words 47 are displayed, for example, from question 1 to question 32. In the example shown in the figure, the question word 47 "piano" is displayed as text.

[0053] The processor 21 also displays two answer buttons: one showing an affirmative answer image 48a indicating that the question word 47 was output as a test word, and another showing a negative answer image 49a indicating that the question word 47 was not output as a test word. The processor 21 also displays a question comment 50, such as "Was this word present?".

[0054] Furthermore, the processor 21 displays a question number mark 51 indicating that the current question is, for example, the 25th question out of 32, and an elapsed time bar 52 showing the time elapsed to answer the 25th question. The time allotted to answer each question can be set arbitrarily, but is set to, for example, about 5 seconds. The affirmative answer image 48a is an example of a first answer image. The negative answer image 49a is an example of a second answer image.

[0055] In the problem image shown in Figure 7, the test-taker touches the affirmative answer image 48a if they remember that "piano" was among the test words, and touches the negative answer image 49a if they remember that it was not. Figure 8 shows the test-taker touching the affirmative answer image 48a. If "piano" was among the test words, a correct answer mark 53 is displayed for the test-taker's answer, as shown in Figure 8. On the other hand, if "piano" was not among the test words, an incorrect answer mark (for example, an "×" image and the word "Incorrect") is displayed.

[0056] As explained in Figures 7 and 8, once the answer to question 25 is completed, the processor 21 displays the image of question 26 on the display screen 11. Figure 9 is an example of the question image displayed on the display screen 11 when answering question 26. As shown in Figure 9, the processor 21 displays "morning glory" as the word 47 in the question image of question 26.

[0057] Furthermore, the processor 21 displays both "morning glory" (problem word 47) and an affirmative answer image 48b indicating that "morning glory" was output as a test word, and a negative answer image 49b indicating that "morning glory" was not output as a test word. At this time, the processor 21 changes the display arrangement of the affirmative answer image 48b and the negative answer image 49b, which are the answer images for question 26, from the display arrangement of the affirmative answer image 48a and the negative answer image 49a, which are the answer images for question 25. Specifically, in the problem image for question 25 shown in Figure 7, the processor 21 displayed the negative answer image 49a on the right side of the display screen 11 and the affirmative answer image 48a on the left side, whereas in the problem image for question 26 shown in Figure 9, the processor 21 displays the affirmative answer image 48b on the right side of the display screen 11 and the negative answer image 49b on the left side. The question number mark 51 indicates that the question is the 26th out of 32 questions. Furthermore, the content displayed for question comment 50 and the elapsed time bar 52 is the same as in question 25.

[0058] In the problem image shown in Figure 9, the processing after the examinee answers by touch operation is the same as the processing for answering question 25 above.

[0059] <Changes to the display of the answer image> The display method of the answer image in question 26, "Morning Glory," as described above, involves a change in the arrangement of the display compared to the display method of the answer image in question 25, "Piano," but is not limited to this.

[0060] <Change Display Pattern 1> Figure 10 shows one of the modified display modes for the answer image in question 26, "Morning Glory". As shown in Figure 10, the processor 21 may change the display interval between the affirmative answer image 48c and the negative answer image 49c, which are the answer images for question 26, "Morning Glory," from the display interval between the affirmative answer image 48a and the negative answer image 49a, which are the answer images for question 25, "Piano." Specifically, the processor 21 may make the display interval between the affirmative answer image 48c and the negative answer image 49c displayed on the display screen 11 in the question image for question 26, "Morning Glory," shown in Figure 10, smaller than the display interval between the affirmative answer image 48a and the negative answer image 49a displayed on the display screen 11 in the question image for question 25, "Piano," shown in Figure 7.

[0061] <Change Display Pattern 2> Figure 11 shows the second modified display method for the answer image in question 26, "Morning Glory." As shown in Figure 11, the processor 21 may change the design of the answer image in question 26, "Morning Glory," from the design of the answer image in question 25, "Piano." Specifically, while the processor 21 displays the background images of the affirmative answer image 48a and negative answer image 49a, which are the answer images for question 25, "Piano," as colorless, it may display the background image 54 of the affirmative answer image 48d and negative answer image 49d, which are the answer images for question 26, "Morning Glory," as colored, as shown in Figure 11. However, "answer image design" may refer to information conveyed to the test-taker (text information such as "piano" and "morning glory") or information related to appearance (design) (such as the color and font of the background image of the answer image), other than the design of elements included in the answer image such as "○," "×," "yes," and "no." Alternatively, it may refer to the design of the appearance of the answer image.

[0062] <Change Display Method 3> Figure 12 shows a modified display method 3 for the answer image in question 26, "morning glory." As shown in Figure 12, the processor 21 may change the timing of displaying the affirmative answer image 48e and the negative answer image 49e, which are the answer images for question 26, "morning glory," from the timing of displaying the affirmative answer image 48a and the negative answer image 49a, which are the answer images for question 25, "piano." Specifically, in the question image for question 25, "piano," shown in Figure 7, the processor 21 displays "piano" (question word 47), the affirmative answer image 48a, and the negative answer image 49a simultaneously on the display screen 11, whereas in the question image for question 26, "morning glory," shown in Figure 12, the processor 21 may first display "morning glory" (question word 47) on the display screen 11, and then display the affirmative answer image 48c and the negative answer image 49c a little later (for example, 0.5 seconds later).

[0063] <Change Display Pattern 4> Figure 13 shows the fourth modified display mode for the answer image in question 26, "Morning Glory." As shown in Figure 13, the processor 21 may change the display size of the affirmative answer image 48f and the negative answer image 49f, which are the answer images for question 26, "Morning Glory," from the display size of the affirmative answer image 48a and the negative answer image 49a, which are the answer images for question 25, "Piano." Specifically, the processor 21 may make the display size of the affirmative answer image 48f and the negative answer image 49f displayed on the display screen 11 in the question image for question 25, "Piano," shown in Figure 7, larger than the display size of the affirmative answer image 48a and the negative answer image 49f displayed on the display screen 11 in the question image for question 26, "Morning Glory," shown in Figure 13.

[0064] <Change Display Pattern 5> Figure 14 shows the modified display method 5 for the answer image in question 26, "Morning Glory". As shown in Figure 14, the processor 21 may change the type of characters displayed for the affirmative answer image 48g and negative answer image 49g, which are the answer images for question 26, "Morning Glory," from the type of characters displayed for the affirmative answer image 48a and negative answer image 49a, which are the answer images for question 25, "Piano." Specifically, while the processor 21 displays the characters of the affirmative answer image 48a and negative answer image 49a displayed on the display screen 11 in the question image for question 25, "Piano," shown in Figure 7, in hiragana, the processor 21 may display the characters of the affirmative answer image 48g and negative answer image 49g displayed on the display screen 11 in the question image for question 26, "Morning Glory," shown in Figure 14, using a string that includes kanji.

[0065] <Change Display Pattern 6> Figure 15 shows a modified display mode 6 of the answer image for question 26, "Morning Glory". As shown in Figure 15, the processor 21 may change the display shape of the affirmative answer image 48h and the negative answer image 49h, which are the answer images for question 26, "Morning Glory," from the display shape of the affirmative answer image 48a and the negative answer image 49a, which are the answer images for question 25, "Piano." Specifically, while the processor 21 displays the answer buttons that display the affirmative answer image 48a and the negative answer image 49a as rectangular shapes in the question image for question 25, "Piano," shown in Figure 7, the processor 21 may display the answer buttons that display the affirmative answer image 48h and the negative answer image 49h as rectangular shapes with rounded corners or as roughly circular shapes in the question image for question 26, "Morning Glory," shown in Figure 15.

[0066] <Change Display Pattern 7> Figure 16 shows a modified display method 7 of the answer image for question 26, "Morning Glory". As shown in Figure 16, the processor 21 may move the display position of the affirmative answer image 48i and the negative answer image 49i, which are the answer images for question 26, "Morning Glory," on the display screen 11. Specifically, the processor 21 may move the affirmative answer image 48i and the negative answer image 49i back and forth in opposite directions in the left-right direction on the display screen 11, displaying the two images by bringing them closer together or further apart. Note that the direction of movement of the answer images is not limited to the left-right direction.

[0067] <Other types of display changes> The processor 21 may, for example, display multiple copies each of the affirmative answer image 48j and the negative answer image 49j, which are the answer images, on the display screen 11, as shown in Figure 17. Alternatively, the processor 21 may, for example, in the example shown in Figure 9, display the affirmative answer image 48k and the negative answer image 49k, which are the answer images, while increasing or decreasing their display size over time, as shown in Figure 18.

[0068] <Result output processing in step S14> Once the answer reception process in step S13 is complete, the processor 21 executes a result output process to inform the user of the test results. Upon transitioning from the answer reception process to the result output process, the processor 21 displays a result screen mark 41d to indicate that the current process is the result output process, as shown in Figure 19, along with a test result 55 indicating that 31 out of 32 questions were answered correctly, and a comment 56 such as, "Well done! That's a very good result!!"

[0069] In this example, we have described a case where the test result (for example, the number of correct answers out of 32) is output by determining whether each word (including dummy words) output in the answer reception process is a test word presented in the output process. However, the processor 21 may also output as the test result the number of test words (excluding dummy words) presented in the output process that were answered as test words when output in the answer reception process (for example, the number of correct answers out of 16).

[0070] As explained above, the cognitive function testing device 1 changes the display mode of the answer images (affirmative answer images and negative answer images) for answering a question word when switching question words displayed on the information terminal 10. As a result, the changing display mode of the answer images increases the examinee's sense of tension, which can prevent the examinee from mindlessly touching the answer images when answering multiple questions displayed sequentially on the information terminal 10, thereby improving the accuracy of the test.

[0071] For example, when the cognitive function testing device 1 switches the question words displayed on the information terminal 10, it reverses the display arrangement of the affirmative answer image 48b and the negative answer image 49b from the display arrangement of the affirmative answer image 48a and the negative answer image 49a (Figure 7), as shown in Figure 9. This prevents the test-taker from mindlessly touching the answer images for multiple questions that are displayed sequentially.

[0072] Furthermore, for example, when the cognitive function testing device 1 switches the question words displayed on the information terminal 10, it changes the display interval between the affirmative answer image 48c and the negative answer image 49c to be smaller than the display interval between the affirmative answer image 48a and the negative answer image 49a (Figure 7), as shown in Figure 10. This prevents the test-taker from mindlessly touching the answer images for multiple questions that are displayed sequentially.

[0073] Furthermore, for example, when the cognitive function testing device 1 switches the question words displayed on the information terminal 10, it changes the background image 54 of the affirmative answer image 48d and the negative answer image 49d to a different design from the colorless background image (Figure 7) of the affirmative answer image 48a and the negative answer image 49a, as shown in Figure 11. This prevents the test-taker from mindlessly touching the answer images for multiple questions that are displayed sequentially.

[0074] Furthermore, for example, when the cognitive function testing device 1 switches the question word displayed on the information terminal 10, it delays the display timing of the affirmative answer image 48e and the negative answer image 49e slightly compared to the display timing of the answer image "morning glory," as shown in Figure 12. This differs from the case where the affirmative answer image 48a and the negative answer image 49a and the question word "piano" are displayed simultaneously (Figure 7). This prevents the test-taker from mindlessly touching the answer images for multiple questions that are displayed sequentially.

[0075] Furthermore, for example, when the cognitive function testing device 1 switches the question words displayed on the information terminal 10, it changes the display size of the affirmative answer image 48f and the negative answer image 49f to be larger than the display size of the affirmative answer image 48a and the negative answer image 49a (Figure 7), as shown in Figure 13. This prevents the test-taker from mindlessly touching the answer images for multiple questions that are displayed sequentially.

[0076] Furthermore, for example, when the cognitive function testing device 1 switches the question words displayed on the information terminal 10, it uses kanji characters for the affirmative answer image 48g and the negative answer image 49g, as shown in Figure 14, to differentiate them from the hiragana display (Figure 7) of the affirmative answer image 48a and the negative answer image 49a. This prevents the test-taker from mindlessly touching the answer images for multiple questions that are displayed sequentially.

[0077] Furthermore, for example, when the cognitive function testing device 1 switches the question words displayed on the information terminal 10, it makes the display shapes of the affirmative answer image 48h and the negative answer image 49h circular, as shown in Figure 15, thus differentiating them from the rectangular shapes of the affirmative answer image 48a and the negative answer image 49a (Figure 7). This prevents the test-taker from mindlessly touching the answer images for multiple questions that are displayed sequentially.

[0078] Furthermore, for example, when the cognitive function testing device 1 switches the question words displayed on the information terminal 10, it moves the display positions of the affirmative answer image 48i and the negative answer image 49i on the display screen 11, as shown in Figure 16, thus differing from the case where the display positions of the affirmative answer image 48a and the negative answer image 49a are not moved (Figure 7). This prevents the test-taker from mindlessly touching the answer images for multiple questions that are displayed sequentially.
