  Hereinafter, embodiments of the present invention will be described in detail for each example.

FIG. 1 is a functional block diagram illustrating an example of a rehabilitation apparatus.
First, after explaining the outline of this figure, the rehabilitation movement and the operation of detecting and analyzing this movement by a computer and changing the art image will be explained. This figure shows that the user 23 moves the upper limb by rotating the shoulder joint and bending and stretching the elbow. In the illustrated example, the user 23 holds the towel 24 with his left hand and exercises to wipe the upper surface of the table 22. The personal computer 14 is a computer that observes the motion of the user 23 through the camera 18 and calculates the evaluation.

  The existing rehabilitation support device physically measures rehabilitation movements such as the rotation of the shoulder joint and the bending and stretching of the elbow of the user 23, and counts and records, for example, what kind of movement is performed. Display the result as a comment. On the other hand, in the present invention, repeated exercises are evaluated each time, and an art image corresponding to the achievement level is displayed.

  With such processing, the user 23 can enjoy the art image itself and the process of changing the image. In the example of FIG. 1, the projector 20 projects an art image generated by the personal computer 14 on a table 22. The user 23 can enjoy the pleasure of creating an art image while moving the towel 24. The completed art image can be printed by the printer 16.

(Computer)
For this analysis process, the personal computer 14 stores necessary data in the storage device 28 and executes arithmetic processing by the arithmetic processing unit 30. The main data stored in the storage device 28 includes a screen 44 for selecting a part, a screen 46 for explaining an operation method, a screen 48 for setting an evaluation standard, a maximum movable distance 50, a target part 52, and a measured movement. Distance 54, achievement level 56, image parts library 57, and the like. Specific examples of data will be described later.

  The arithmetic processing unit 30 is provided with an arithmetic processing module realized by a computer program. The main arithmetic processing modules are target part evaluation setting means 32, motion detection means 34, motion evaluation means 36, image processing means 42, and the like.

  The target part evaluation setting unit 32 has a function of setting an evaluation standard for evaluating the rehabilitation movement of the part 52 to be rehabilitated, for example, the upper limb, for example, the maximum movable distance 50. The motion detection means 34 has a function of detecting the rehabilitation movement of the user 23 and measuring the amount of movement, the direction of movement, or the speed of movement of a part to be rehabilitated.

  The motion evaluation means 36 has a function of evaluating the detected rehabilitation exercise and obtaining the achievement level 56 in comparison with the evaluation standard. The image processing unit 42 has a function of updating the screen displayed on the image display device, for example, the projector 20 so as to change the content and image quality of the image corresponding to the achievement level 56 by the motion evaluation unit 36 when the rehabilitation exercise is repeated. have. More specific examples of these means will be described later.

(Initial setting)
2-4 is explanatory drawing of a display screen for rehabilitation exercise support of an upper limb. 2A is a start screen, FIG. 2B is a screen 44 for selecting a part, FIG. 3A is a screen for selecting an art image to be created, and FIG. 3B is a completed state with the selected art image. FIGS. 4A and 4B are screens 46 for explaining the operation method, and FIGS. 5 to 7 are explanatory diagrams of specific examples of the screen 48 for setting evaluation criteria.

  The personal computer 14 first displays on the display a screen 44 for selecting a rehabilitation target site, as shown in FIG. In this example, the user 23 is made to select left hand or right hand. When you put the corresponding hand on the screen, the computer detects this and recognizes which hand rehabilitation movement. In addition to the upper limb, the lower limb or the like can be selected.

  The art image desired by the user is selected on the screen shown in FIG. That is, it is preferable that the art image to be displayed can be freely selected by the user, such as a picture or a photograph. Then, the completed state of the selected art image is shown in FIG. 3B, and the rehabilitation exercise is guided to start with this as a target.

  Next, the screen of FIG. 4A is displayed. Here, how to perform rehabilitation exercises, an operation method is shown by an image. Further, the user is requested to move his hand several times as much as possible on this screen. The computer recognizes the maximum movable distance 50 and stores it in the storage device 28. By this operation, the user can understand the exercise method and the goal. Furthermore, by detecting the user's own movement in the preparation process before starting the movement evaluation, the evaluation standard for the rehabilitation exercise can be automatically set in the computer. Thereafter, support for rehabilitation exercise is started by placing a hand on the screen of FIG.

  That is, in this example, the computer analyzes the movement by repeating the movement of wiping the table with a towel. The marker 26 displayed on the towel is photographed by the camera 18. The screen of FIG. 4B is shown so that the movement of the upper limb enters the field of view of the camera 18. In addition to this, as will be described later, any method that can detect the rehabilitation movement according to the type of the target region can be employed.

FIG. 5 to FIG. 7 are explanatory diagrams for explaining a rehabilitation exercise evaluation method.
Three kinds of evaluation criteria are displayed at the top of these drawings. The target moving distance is as shown in FIG. When the detected rehabilitation movement of the user is determined to be a movement of 69% or less of the target moving distance, the evaluation is set to C rank. If it is determined that the movement is between 70% and 89% of the target moving distance, the evaluation is B rank. If it is determined that the movement is 90% or more of the target moving distance, the evaluation is A rank.

  Such evaluation criteria may be set in advance by an expert who teaches rehabilitation. Of course, the user himself / herself can be set. A program is prepared in which an art image is completed when the upper limbs are moved 50 or 100 times. In 50 programs, one set of 10 rehabilitation exercises. In 100 programs, one set is counted when 20 rehabilitation exercises are performed. Then, a part image of a part of the art image is sequentially added and projected for each set. The number of times for each set may be set freely by the user.

  One area corresponding to the additional part 62 in the image 60 to be displayed is additionally displayed for each set. The drawings illustrate the internal processing of the computer. The image to be displayed is shifted sequentially from the left end to the left by a width corresponding to one part. Only the image on the left side of the area corresponding to the additional part 62 is displayed on the display.

  In the area corresponding to the additional part 62, the original image is converted and output according to the rank of the evaluation. In the example of FIG. 5, when the evaluation is C rank, the parts are displayed after being converted into a coarse mosaic image. If the evaluation is B rank, the image is displayed after being converted into a fine mosaic image. When the evaluation is A rank, a clear part obtained by cutting the original image is displayed.

  In the example of FIG. 6, when the evaluation is C rank, the part is displayed after being converted into a monochrome image. If the evaluation is B rank, the number of display colors is reduced before being displayed. When the evaluation is A rank, the original image is displayed as it is. In the example of FIG. 7, when the evaluation is C rank, an image converted into a pencil drawing is displayed. When the evaluation is B rank, an image converted into an ink painting is displayed. When the evaluation is A rank, the original image is displayed as it is. In this case, in the area corresponding to the additional part 62, another image data may be cut out without converting the original image.

FIG. 8A shows a completed image example in the case of FIG. 5, and FIG. 8B shows a completed image example in the case of FIG.
In the example of FIG. 8A, the evaluation of the second set and the fifth set is A rank, and clear images of only the parts 58-2 and 58-5 of the portion are displayed. The evaluation of the third set is rank B, and the part 58-3 in that portion is a fine mosaic image. The evaluation of the first set and the fourth set is C rank, and the parts 58-1 and 58-4 of the part are coarse mosaic images. Further, in the example of FIG. 8B, the evaluation of the second set and the fourth set is A rank, and clear images of only the parts 58-2 and 58-4 are displayed. The third set, 58-3, is rated C, so it is displayed as a pencil drawing. Since the evaluations of the parts 58-1 and 58-5 of the first set and the fifth set are B ranks, an ink painting is displayed. Since color images cannot be expressed in the application drawings, illustration is omitted.

FIG. 9 is an explanatory diagram of an evaluation example of rehabilitation exercise.
For example, the image illustrated in FIG. 8A is displayed as a result of the processing shown in this figure. On the left, the degree of achievement of the maximum movable distance 50 is shown by the height of the bar graph. In this example, one set was set to 10 times and 50 sets were set to 5 sets, and the achievement level of each set was shown by a bar graph. The average value 54 of the movement distance measured in the first set is 62% of the maximum movable distance 50 and the evaluation is C rank, and the average value 54 of the movement distance measured in the second set is evaluated as 95% of the maximum movable distance 50. The average value 54 of the travel distance measured in the A rank and the third set is 76% of the maximum movable distance 50, and the evaluation is B rank. The average value 54 of the travel distance measured in the fourth set is the maximum travel distance 50 Evaluation is 68% at C rank, average value 54 of the measured movement distance in the fifth set is 95% of the maximum movable distance 50, and evaluation is A rank.

(Function of the motion detection means 34)
Here, the function of each module of the arithmetic processing unit shown in FIG. 1 will be described in more detail. For example, the sanding operation has been described in the example of FIG. 1 as a rehabilitation exercise for the purpose of strengthening the strength of the upper limbs or improving the range of motion of the joint. This operation is an exercise of bending or extending the upper limb by performing an operation of wiping the desk with a hand on the towel 24. The marker 26 is attached to the towel 24 held in the hand, and the moving marker 26 is photographed by the camera 18 of the computer.

  The marker 26 moves integrally with the part 52 to be rehabilitated. The marker 26 is realized by a mark or a light emitter that can be clearly photographed by the camera 18. Inside the computer, the moving distance, moving direction, moving speed, and the like of the hand are measured by calculation processing from the locus of the marker 26 in the photographed image. When the movement of the marker 26 is a curve, the movement distance may be obtained along the curve if the movement direction is within an appropriate range. This movement distance corresponds to the amount of flexion or extension movement of the shoulder, hand, or upper limb. As the motion detection means 34, any known sensor or the like can be used. For example, a joystick that can directly detect rehabilitation movement, a mouse, a touch panel, or the like can also be used. Further, a non-contact type distance image sensor can be used. It is also possible to detect movement by attaching a sensor to a hand or finger.

(Function of the motion evaluation means 36)
The computer stores in advance in the storage device 28 the condition that the target of rehabilitation is the upper limb and the target maximum movable distance 50. The target part evaluation setting means 32 (FIG. 1) sets the maximum movable distance 50 of the part 52 to be rehabilitated as 100% as an evaluation criterion. Then, the achievement ratio of the measured movement distance 54 with respect to the maximum movable distance 50 (FIG. 9) is calculated, and this is set as the achievement level 56.

  For example, in a program in which one set is 10 times and exercise is completed in 50 times, nothing is displayed in the corresponding area at the time of the first to fifth movements of one set (10 times). During the operation from the sixth time to the tenth time, for example, an image of the corresponding part is projected when the achievement level is less than 69%. When the 10th set is completed, the average travel distance for 10 times is calculated. The ratio of this average moving distance to the maximum movable distance is the achievement level. A part image corresponding to this achievement is selected and projected. Such programs can encourage users to actively exercise.

  That is, when the rehabilitation exercise is repeated N times in total, the N times are divided into a plurality (M) of sets, and the area of the art image to be displayed is also divided into M. Then, when the exercise is completed a predetermined number of times for each set, an art image to be displayed in the corresponding area is selected and displayed according to the achievement level. Thus, the user can check the evaluation of the operation for each set, that is, the degree of achievement with respect to the evaluation standard. The number of exercises for each set may be set arbitrarily. All sets need not have the same number of exercises.

  Furthermore, at any timing during the set, a part image that can be compared with the target achievement level is temporarily displayed. After the set is completed, the average value of the number of exercises determined for each set is calculated and the evaluation criteria A degree of achievement is obtained from the ratio to the above, and a part image corresponding to the degree of achievement is selected and projected. If the part image displayed after the end of the set is equivalent to the temporarily displayed part image, or if the image quality is better, the user can feel a sense of accomplishment with respect to the exercise. On the contrary, if the part image displayed after the set is finished is inferior to the temporarily displayed part image, there is an effect that the user is conscious of trying hard in the next part image movement. In addition, by starting the temporary display of the part image in the middle of the exercise, the displayed image becomes image information of the part image after the set is completed and encourages the exercise being executed.

FIG. 10 shows an example of the motion detection means 34, and FIG. 11 shows an example of an art image drawn using the motion detection means 34.
Two types of motion detection means 34 are displayed. The left side includes an air pump 74 that blows out air when grasped by a palm, and a sensor 76 that detects the pressure, amount, sound, or temperature of the air blown out by the air pump 74. The pressure can be detected by a pressure sensor. The amount can be detected by rotating a fan or the like. A sound generated by a lead that vibrates due to an air current may be detected by a microphone. Further, when the air flows and the temperature decreases, this can be detected by the temperature sensor.

  The means 36 (FIG. 1) evaluates the output of the motion detection means 34. The air pump 74 is useful for the grasping operation of the hand 72 and the rehabilitation of fingers and the like. In addition, as shown on the right side of this figure, when breath is blown from the mouth 73, it can be said that the expiration detector 77 detects and the motion evaluation means 36 evaluates. The breath detector 77 may be any sensor that is exactly the same as when the air pump 74 is used. That is, it is preferable to detect the pressure, volume, sound, temperature, or air flow of the breath that has been blown. The breath detector 77 can be used when respiratory motion is a target for rehabilitation.

  FIG. 11 shows an operation example of the apparatus using the operation detecting means 34 using the pressure sensor 76. Thereby, it can enjoy and perform the rehabilitation exercise | movement for recovering the operation | movement which grasps an object, and grip strength. The user is prompted to select a background image on the first screen (a). In (b), four types of background images are displayed. One of the background images is selected by screen operation of the computer touch panel.

  Next, a color is selected on the screen of (c). On the screens (d) and (e), the user is informed that the part of the artwork (parts, jellyfish, color, shape, swimming direction, etc.) changes when the air pump 74 is held. It can be a still image or a video. By the operation of gripping the air pump 74, the displayed image and the state of the parts 58 in the image are switched in order.

  If there is a jellyfish appearing, changing direction, swimming or stopping, an unpredictable change, etc., the operation of gripping the air pump 74 becomes more intense. After that, the completed screen can be viewed and printed, resulting in an improvement in the quality of the deliverables and motivation for continuous rehabilitation.

  In other words, the design elements of the displayed image and the parts of the artwork in the image are linked with the screen operation of the computer touch panel and the operation (operation such as holding the air pump or blowing air) linked to the sensor (pressure, sound, temperature, etc.). By changing the contents (background, color, shape, material, etc.), arrangement, number, etc., you can enjoy the enjoyment of art works while performing rehabilitation exercises.

FIG. 12 is an explanatory diagram of an example in which another motion detection unit is used.
Some rehabilitation exercises use a chair 84 to stand and sit. For example, this can be detected by a gyro sensor or the like built in a portable terminal worn by a user. You can also use an interface (Kinect) developed by Microsoft. Such a sensor can be used for a locomotion training program for the elderly that incorporates knee flexion / extension motion and abdominal back muscle motion.

  In the example shown in FIG. 12, the user 23 wears the head mounted display 94. For example, a gyro sensor, a transmitter that transmits the detected signal to the personal computer 14 shown in FIG. 1, and a display that three-dimensionally displays an image generated by the personal computer 14 are built in the head mounted display 94. Keep it.

  In this embodiment, when the user 23 is sitting on the chair 84, the underwater image 88 is visible. When the user 23 stands up, the sky image 90 on the sea surface can be seen. The operation evaluation means 36 evaluates the number of times of standing by this operation. If the evaluation is low, the image quality of the landscape projected in the sky is low, and if the evaluation is high, the image quality of the landscape projected in the sky increases.

  The image 90 on the sea surface is initially only an image of the sky, and the completed image is a beautiful landscape image such as a World Heritage site. It is assumed that the parts are disassembled into pieces in a jigsaw puzzle with respect to the completed image. When the rehabilitation movement of standing and sitting is repeated, the image 90 on the sea surface gradually approaches completion. In this embodiment, the evaluation of the rehabilitation movement corresponds to the width of the image 90 on the sea surface seen above the underwater image 88, and the number of parts increases in proportion to the number of rehabilitation movements. In this way, it is possible to perform control by evaluating the maximum momentum.

  In the above-described embodiment, the addition of the low-quality part image is completed by a certain number of rehabilitation exercises, the whole image is presented, and the change in the aspect of the part image is changed from the higher number of exercises to the higher image quality. If you want to complete a higher quality image, you can increase your motivation for rehabilitation.

  In this embodiment, the image changes with respect to the rehabilitation motion of the standing and sitting motion, but the upper limb and lower limb rehabilitation can be performed simultaneously by detecting the motion of the upper limb and reflecting it in the change of the image.

  In this way, the achievement ratio of the artwork (parts) (image resolution, number of colors, type of material, etc.) and rehabilitation exercise are linked, and the goal achievement ratio is large (the movement distance and the momentum are large). , Make it work better. Depending on the number of standing and sitting, the quality of the part (parts) of the artwork (parts) to be projected (created) is different (image resolution, number of colors, material type, etc.), and the achievement level is large (the number of times is high, the attitude The better, etc.) the better the performance. Furthermore, physical information such as posture may be evaluated as the performance of the rehabilitation exercise.

In the above-described embodiments, examples in which the part image is changed to various modes have been described. However, the present invention is not limited to these embodiments.
As described above, the content and image quality of art images gradually change as the user repeats a high-quality rehabilitation exercise, so that the user can continue to enjoy the mechanical rehabilitation exercise. In addition, the degree of achievement of rehabilitation is fed back as a work of art images, which leads to continuous motivation for rehabilitation. Furthermore, the above-described rehabilitation support device can be used not only for functional recovery for a failure that has occurred, but also for exercise for maintaining or recovering the function of a site whose function is reduced by aging.

The above apparatus is as follows when the functions are schematically listed as examples.
(1) The motivation of the user 23 is enhanced by changing the content and image quality of the displayed art image according to the achievement level of the exercise content, triggered by several rehabilitation exercises.
(2) When the trigger is input, the completeness of the image is increased by adding parts to a part of the image or replacing some parts.
(3) Alternatively, the brightness, saturation, hue, or resolution can be changed all at once by replacing the entire image every time a trigger is input.
(4) The image quality can be changed by changing the brightness from a dark image to an image with appropriate brightness.
(5) The image quality can be changed by increasing the contrast from an image having a low contrast.
(6) The image quality can be changed by changing from a black-and-white or gray tone image to a brightly colored image.
(7) The image quality can be changed by sequentially replacing an image with coarse pixels with a fine image.
(8) The screen may be changed like a car window.
(9) It may be an abstract picture whose performance cannot be predicted.
(10) It is also possible to select whether the art image is a still image or a moving image.
(11) When the completed image is divided into parts and the image quality is changed for each set as in the above embodiment, it is possible to confirm the process in which the rehabilitation movement is gradually improved.

  The program used in the present invention described above is a creative program for creating an art work to support the rehabilitation movement. For example, the “Active Art (active art) program” or “Active Art (active art) rehabilitation”. "Program" can be generically named. In addition, each program having a single function is given a title such as “Let's draw a jellyfish!”, “Get up and draw in the sky!”, “Let's wipe and draw a picture!” If you make it interesting, you can broaden the usage.
