[0032] Next, the operations of the hand operating unit 5 and the foot operating unit 6 will be described. Figure 4A , 4B This is a side view of the main body of the exercise device 1 and its vicinity as seen from the left side, with the chair portion 2 and the main body cover omitted. Figure 4A Indicates the situation when the left foot steps in. Figure 4B Indicates the situation when the right foot steps in. The left hand operating part 5L and the right foot operating part 6R are connected by the sixth connecting shaft 21, so for example, when the top end (handle 5Lb) of the left hand operating part 5L moves from the back to the front, the right foot operating part 6R also moves in a linkage manner from the back to the front. Similarly, the right hand operating part 5R and the left foot operating part 6L are connected by the fourth connecting shaft 19, so they move in a linkage manner. In addition, the first link piece 16 and the second link piece 17 move in a linkage manner through the first belt 28 and the second belt 32. For example, if the upper end of the first link piece 16 moves from the back to the front by operating the left foot operating part 6L, the upper end of the second link piece 17 moves from the front to the back. That is, the hand operating part 5 and the foot operating part 6 are configured such that when the trainer who uses the exercise device 1 to exercise has the left foot and the right hand located in the front, the right foot and the left hand are located in the back, and when the right foot and the left hand are located in the front, the left foot and the right hand are located in the back.

[0033] In the exercise device 1, as an exercise mode, at least one of a pulse fixed mode, a load fixed mode, and a watt fixed mode is included. In the pulse fixed mode, the load is increased so that the trainee's pulse approaches the target value. In the load fixed mode, the load is increased until it reaches a set load level. In the watt fixed mode, the load is increased to reach a set wattage. The wattage is a numerical value indicating the amount of exercise of the trainee.

[0034] Next, use the block diagram Figure 5The control structure of the exercise device 1 is described. The exercise device 1 includes a power switch 39, a power circuit 40, a communication module 41, magnetic sensors (reed switches) 42a, 42b, a rotation information input circuit 43, a pulse detection circuit 44, a main control unit 45, a load control unit 46, a sound output circuit 47, a speaker 48, a storage unit 49, and the aforementioned personal computer 7, the load unit unit 37, the hand operation unit 5, and the foot operation unit 6. A single-phase power supply 50 is supplied to the power circuit 40 via the power switch 39, and a voltage is supplied from the power circuit 40 to the communication module 41, the pulse detection circuit 44, the main control unit 45, and the load control unit 46. The main control unit 45 controls the personal computer 7, the load control unit 46, the sound output circuit 47, and the storage unit 49, and is composed of a microcontroller (microcomputer). The communication module 41 is used to send information such as data of exercise results to a tablet terminal (not shown), and can perform wireless communication, for example, via Bluetooth (registered trademark). The magnetic sensors 42a and 42b detect pulse waves related to the rotation speed of the load cell unit 37 and the number of steps of the hand operation unit 5 and the foot operation unit 6, and input them into the rotation information input circuit 43. The rotation information input circuit 43 outputs a count signal from which noise of the pulse wave is removed to the main control unit 45, and the main control unit 45 calculates the calories consumed by the exercise based on the count signal. The pulse detection circuit 44 removes noise from the pulse signal detected by the ear sensor 51 attached to the earlobe of the trainee and outputs it to the main control unit 45, and the main control unit 45 detects the pulse rate of the trainee based on the pulse signal. The pulse signal is detected by the ear sensor 51 emitting infrared light and receiving infrared light reflected by the blood vessels, and the pulse detection circuit 44 adjusts the intensity of the infrared light so that the pulse signal can be detected. The load control unit 46 controls the load cell unit 37 to change the load applied to the hand operation unit 5 and the foot operation unit 6. The personal computer 7 includes a control unit 52, a display unit (display means) 53, a storage unit 54, a microphone (sound collection means) 55, and a speaker 56. The display unit 53 is, for example, a liquid crystal touch panel, and information can be input by touching the display unit 53 with the trainee's finger or the like. The control unit 52 is composed of a microcomputer, and includes a question setting unit 52a, a manual input recognition unit (manual input recognition mechanism) 52b, a determination unit (determination mechanism) 52c, a voice recognition unit (voice recognition mechanism) 52d, and a voice synthesis unit 52e.

[0035] In the exercise device 1, a multi-task exercise can be performed in which questions are asked to the trainee while the trainee moves the hand operation unit 5 and the foot operation unit 6 to exercise. At least one of the pulse fixed mode, the load fixed mode, and the watt fixed mode can be used as the exercise mode. The question selected by the question-posing unit 52a from the questions stored in the storage unit 54 is displayed on the display unit 53, and the trainee answers the question by speaking, and the sound generated by the speaking is collected by the microphone 55. Based on the sound collected by the microphone 55, the content of the answer is recognized by the sound recognition unit 52d. The judgment unit 52c determines whether the content of the answer recognized by the sound recognition unit 52d is a correct answer. In this way, the trainee understands the content of the question asked while exercising the upper limbs and lower limbs using the hand operation unit 5 and the foot operation unit 6, solves the problem and answers it by speaking, so that training that promotes brain activation can be performed. In addition, regarding the question-posing to the trainee, the question can be displayed on the display unit 53, and the question can be read aloud, or the question and the answer options can be read aloud to perform the question by voice, or the question can be only asked by voice. In the case of asking questions by voice, the voice synthesizer 52e converts the question into a voice signal and emits the voice from the speaker 56. Thus, the question or the question and the answer options can be confirmed by voice. Here, the question-asking mechanism for asking questions to the trainee has the question-asking mechanism 52a, and in the case of asking questions by display, the question-asking mechanism further has the display unit 53. In addition, in the case of asking questions by voice, the question-asking mechanism further has the voice synthesizer 52e and the speaker 56.

[0036] The questions asked to the trainees include questions on overcoming at least one of memory impairment (loss of past memories, difficulty remembering new things), executive dysfunction (difficulty doing things in order), attention dysfunction (distraction and inability to focus on one thing), disorientation (difficulty recognizing time, place, and people), and visual-spatial cognitive impairment. Visual-spatial cognitive impairment includes hemispatial neglect, which is difficulty recognizing the space on the opposite side of the damaged cerebral hemisphere, and topographic disorientation, which is getting lost in familiar roads and being unable to remember new routes. The questions used to overcome each obstacle include questions related to at least one of language, arithmetic, science, and society, and questions of low, medium, and high difficulty levels are prepared. Examples of questions include: Figure 6A to Figure 6E shown. Fig. 6A These are language-related questions that are used to overcome memory impairment, executive dysfunction, attention dysfunction, and visual-spatial cognitive impairment, and they have a high degree of difficulty. Figure 6B These are problems related to arithmetic and are used to overcome memory impairment, executive dysfunction, attention dysfunction, and visual-spatial cognitive impairment, and are of medium difficulty. Figure 6CThese are science-related questions designed to help students overcome memory impairment and disorientation problems, and are of medium difficulty. Fig.6D These are questions that are socially relevant and are used to overcome memory impairment and disorientation, and are of medium difficulty. Fig. 6E These are socially relevant questions that are used to overcome memory impairment, disorientation, and visual-spatial cognitive impairment, and are of medium difficulty. Fig. 6A , 6C 6D is a question where you choose to answer from the options. Figure 6B , 6E It is a question that is answered with free words.

[0037] Next, the method of multi-task exercise (training in multi-task mode) is described by taking the case where the exercise mode is a pulse fixed mode as an example. Hereinafter, the training in multi-task mode is referred to as training. The trainee sits on the chair portion 2 of the exercise device 1, attaches the ear sensor 51 to the earlobe of the trainee, and then sets the training conditions. Fig. 7A , 7B An example of a condition setting screen before starting training is shown, which is displayed on the display unit 53 when multi-task exercise using the pulse fixed mode is selected. Fig. 7A This is a common setting screen. For each item used to identify the patient's patient ID, exercise time (minutes), upper pulse rate (BPM), upper pulse rate (BPM), lower pulse rate (BPM), age (years), and weight (kg), you can enter the set value by touching the part where the value is displayed. Here, if the trainee's pulse is less than the value set for the lower pulse rate, the training is temporarily stopped. If the trainee's pulse exceeds the value set for the upper pulse rate, the training is temporarily stopped. If the trainee's pulse exceeds the value set for the upper pulse rate, the training is forcibly terminated. In addition, the upper pulse rate value is automatically entered according to the age. If you touch on Fig. 7A The "Detailed Settings" displayed at the bottom of the common settings screen will switch to Figure 7B The detailed setting screen is shown.

[0038] exist Figure 7BIn the detailed setting screen, it is possible to set whether to ask questions for overcoming memory impairment, executive dysfunction, attention dysfunction, disorientation or visual-spatial cognitive impairment, and to set the difficulty of the questions asked. Questions set as "0" in the question-asking column will be asked. The difficulty can be selected from "low", "low·medium", "low·medium·high", and the selected difficulty will be asked. In addition, the answer time, question interval, answer method, answer method, voice output, voice speed and correct answer display can be set. Here, the answer time is the time limit from asking the question to answering, and the next question is transferred if it cannot be answered within the answer time. The answer time can be set in the range of 10 to 200 seconds, or "unlimited" can be set. The question interval is the time from the determination of whether the answer is the correct answer to the next question, which can be set in the range of 1 to 99 seconds. The answer method can be selected from answering with both sound and touch operation, answering with sound only, and answering with touch operation only. The answer method can be selected from free words, answering by selecting from answer options, and answering by both (free words, selecting from answer options), and the question corresponding to the set answer method will be asked. The voice output can be selected from reading only the question text, reading the question text and answer options, and not reading. The voice speed is the speed of the voice broadcast, and can be selected from fast, normal, and slow. The correct answer display can be selected to display the correct answer when the answer is incorrect, or not display it. In addition, if you touch Figure 7B "Common Settings" displayed at the bottom of the detailed settings screen of Fig. 7A If you touch "Start" displayed at the bottom of the common setting screen or detailed setting screen, training starts.

[0039] If the training starts, the message "Please step on the pedal" is displayed on the display unit 53, and the trainee moves the upper limbs and lower limbs to warm up by operating the hand operation unit 5 and the foot operation unit 6. After a predetermined time (for example, 30 seconds) from the start of the warm-up, when the trainee's pulse rate reaches the set lower pulse rate, the trainee starts to ask questions by displaying questions on the display unit 53. In the case that the trainee's pulse rate does not reach the set lower pulse rate even after the aforementioned predetermined time, the warm-up is continued until the set lower pulse rate is reached. If the question is started, the trainee answers the question by speaking while continuing the exercise of the upper limbs and lower limbs. The sound generated by the trainee's speaking is collected by the microphone 55, and the sound recognition unit 52d recognizes the content of the answer based on the sound collected by the microphone 55. Then, the judgment unit 52c judges whether the content of the answer recognized by the sound recognition unit 52d is the correct answer, and the judgment result is reflected on the display unit 53. If the judgment of the answer content is completed, the next question is raised, and the trainee is asked questions until the set exercise time ends. In addition, as a method of answering, when choosing to answer with both sound and touch operation, or to answer only with touch operation, the trainee inputs the answer by touching the display unit 53 with a finger, etc., the manual input recognition unit 52b recognizes the content of the answer, and the judgment unit 52c determines whether the content of the answer is a correct answer.

[0040] Figure 8 This is an example of a screen of the display unit 53 during training. The question is displayed in the area surrounded by dotted lines in the question area 60 in the center of the screen, and the remaining time (seconds) to answer the question is displayed in the form of a countdown at the upper right position 61 in the question area 60. Thus, the trainee can be aware of the time until the answer is given to perform training. As long as the "skip question" displayed in the lower right of the question area 60 is touched, the current question can be transferred to the next question without answering it. "5 / 8" displayed on the upper left side of the question area 60 indicates that the question currently displayed is the eighth question, and the number of questions answered correctly so far is five. "0 points + 30" displayed on the upper center of the question area 60 indicates that the current score is 0 points, and 30 points are generated as a bonus. The name of the bonus and the name of the bonus are displayed on the right side of the display. For example, the name of the bonus "question" is a bonus that adds points for each question asked. In the area 62 at the bottom of the screen, "stop", "interval mark", and "volume mark" are displayed from the left. If "stop" is touched, the training is stopped and transferred to the screen showing the results of this training (described later). If you touch the "interval mark", you can change the number of times the interval sound during training is sounded per minute, and if you touch the "volume mark", you can change the volume of speakers 48 and 56. The interval sound during training is emitted from speaker 48. Figure 7BIf you set the correct answer to be displayed when the answer is incorrect in the correct answer display item on the detailed settings screen of the trainee, the correct answer will be displayed in a pop-up window above the question text if the trainee's answer is incorrect.

[0041] The area 63 on the left side of the question area 60 displays the time (exercise time) elapsed since the start of the exercise with multiple tasks in a bar graph. As time passes, the oblique line portion rises, and when it reaches the top, it becomes the set exercise time. The remaining time of the exercise is displayed on the upper side of the bar graph (in Figure 8 In the bar graph, the value set by the lower pulse number is displayed as the lower pulse limit, and the value set by the upper pulse number is displayed as the upper pulse limit. The trainee can train in such a way that the pulse number is between the lower pulse limit and the upper pulse limit while checking his / her pulse number in the bar graph in the area 65.

[0042] A voice recognition waveform 64 is displayed on the left side of the bar graph representing the exercise time. When the voice recognition function is activated, multiple ellipses 64a rotate slowly. If the voice recognition unit 52d actually recognizes the sound collected by the microphone 55 (the trainer's voice, etc.), the multiple ellipses 64a rotate quickly. By visually confirming the voice recognition waveform 64, it can be known whether the trainer is speaking appropriately. For example, questions are asked to the trainer who is exercising, the trainer listens to the questions asked by voice, and the trainer reads the questions aloud by voice. At this time, it is possible to confirm whether the trainer is speaking appropriately through the voice recognition waveform 64. Moreover, the trainer solves the problem and answers by voice, and it is determined whether the content of the answer is the correct answer. Such training can promote brain activation.

[0043] Here, as mentioned above, the difficulty of the questions to be asked can be set, and the difficulty of the questions can be set according to the degree of the trainee's obstacle. In addition, when the difficulty of the questions is set to "low·medium" or "low·medium·high", the difficulty of the questions to be asked can be changed according to the correct answer status during training. For example, when the previous question and the question before that are answered correctly in succession, the difficulty of the next question to be asked is increased by one level. However, when the current difficulty is "high", the status quo is maintained. When the previous question and the question before that are answered incorrectly in succession, the difficulty of the next question to be asked is reduced by one level. However, when the current difficulty is "low", the status quo is maintained.

[0044] If the exercise time exceeds the set value, the state is changed to cool down, and the screen of the display unit 53 changes from Figure 8 The screen shown switches to a relaxation screen (not shown), and "Thank you for your hard work" is displayed in the upper center of the screen. During the relaxation period, the trainee continues to operate the hand operating unit 5 and the foot operating unit 6. If a predetermined relaxation time (e.g., 5 minutes) has passed, the trainee ends the operation of the hand operating unit 5 and the foot operating unit 6, and the display unit 53 displays the training results of this time. Fig. 9A This is an example of the training results for this time, showing the patient ID, exercise time, number of questions asked, number of correct answers, answer accuracy, score, pulse fix time, and calories consumed. Here, pulse fix time is the time during training when the trainee's pulse rate is within the range of above the set lower pulse rate and below the set upper pulse rate. If you touch Fig. 9A The "Past Comparison" displayed below the Fig. 9B The screen shown in the figure shows the current result on the left side of the screen and the previous result on the right side of the screen. Fig. 9B The "current result" displayed below the Fig. 9A If you touch Fig. 9A , 9B The "Table Data" displayed below will display the current and previous results in table format (e.g. the results of up to 10 training sessions). Fig. 9A , 9B In addition, "Stop" is displayed on the relaxation screen (not shown), and by touching "Stop", the relaxation can be stopped and the display of the training results can be transferred even in the middle of relaxation.

[0045] Here, in the exercise device 1, it is configured to ask questions to the trainee when the trainee's pulse rate is above the set lower pulse rate and below the set upper pulse rate. When the trainee's pulse rate exceeds the set upper pulse rate for a predetermined time (for example, 3 seconds), for example, "The pulse exceeds the set upper pulse rate. Interrupt training. If the pulse is below the upper limit, restart training." is displayed, and the asking of questions to the trainee is temporarily stopped. Furthermore, when the trainee's pulse rate becomes below the set upper pulse rate, the asking of questions to the trainee is restarted. On the other hand, when the trainee's pulse rate is below the set lower pulse rate for a predetermined time (for example, 3 seconds), for example, "The pulse is below the set lower pulse rate. Interrupt training. If the pulse exceeds the set lower pulse rate, restart training." is displayed, and the asking of questions to the trainee is temporarily stopped. Furthermore, when the trainee's pulse rate becomes above the set lower pulse rate, the asking of questions to the trainee is restarted. In addition, if the trainee's pulse rate exceeds the upper limit pulse rate, the state shifts to relaxation.

[0046] In the above embodiment, an example of asking questions to a trainee who is exercising the upper limbs and lower limbs is described, but it is possible to ask questions to a trainee who is exercising either the upper limbs or the lower limbs, so that the trainee understands the content of the question, solves the question and answers it by speaking, thereby promoting training for brain activation. Here, questions can also be asked by voice, and the trainee who listens to the question reads the question aloud by speaking. In the exercise of the upper limbs and lower limbs or in the exercise of the upper limbs, if the question is answered by touching the display unit 53 with the hand, the movement of the upper limb will be hindered, but if the question is answered by speaking, it is possible to prevent the movement of the upper limb from being hindered. Even a trainee who is not good at answering by hand can simply answer the question by speaking. In addition, an example in which the control unit 52 of the personal computer 7 has a manual input recognition unit 52b is described, but it is also possible not to have the manual input recognition unit 52b. In addition, a headset composed of headphones and a microphone can be used instead of the microphone 55.
