The invention will now be described based on the preferred embodiments, which do not intend to limit the scope of the present invention, but exemplify the invention. All of the features and the combinations thereof described in the embodiment are not necessarily essential to the invention. Furthermore, the following describes the present invention by way of an example of an embodiment in which a training assisting apparatus of the present invention is applied to a mental illness treatment assisting apparatus. However, the application of the training assisting apparatus of the present invention is not limited to treatment of mental illnesses.
For example, the assisting apparatus 10 displays on the display section 160 training images showing spider(s) that differ in type, number, size, and the like depending on the physical state of the patient 200. The assisting apparatus 10 may display on the display section 160 training images of animated spider or photographed spider according to the physical state of the patient 200. For example when having judged that there is a possibility that the patient 200 has a panic attack from the measurement result of the biological information measurement section 105, the assisting apparatus 10 displays a training image of an animated spider on the display section 160. On the other hand, when having judged that there is no possibility that the patient 200 has a panic attack, the assisting apparatus 10 displays a training image of a photographed spider on the display section 160.
For a patient 200 having trouble riding on a train due to agoraphobia, the assisting apparatus 10 may also present to the patient 200 by displaying on the display section 160 various training images differing in how many passengers are in a train, in stations to be stopped at by displaying the training images or the like. The assisting apparatus 10 may display on the display section 160 various images such as an empty train where there is hardly any passenger, or a crowded train packed with passengers, depending on the physical state of the patient 200. The assisting apparatus 10 may extract an image of the patient 200 from a photograph in which the image of the patient 200 is captured, for combining the image of the patient 200 with training images. The assisting apparatus 10 may also show training images into which the image of the patient 200 has been incorporated to the patient 200. Note that the physical state of the patient 200 is identified by the image of the patient 200 captured by the image-capturing section 100, as well as the physical state of the patient 200 measured by the biological information measurement section 105. The physical state of the patient 200 may be information showing existence/nonexistence of blinks, the number of times of blinks per unit time, how the face looks down, change in the size of the pupils, existence/nonexistence of perspiration, change in blood pressure, etc., pertaining to the patient 200.
Furthermore, the assisting apparatus 10 may change the information quantity and the strength of a training image step by step depending on the physical state of a patient 200, and display on the display section 160 the training image of which the information quantity and the strength are changed. For example, the assisting apparatus 10 detects change of the physical state of the patient 200 looking at the display section 160 on real time basis. Then the assisting apparatus 10 displays on the display section 160 a training image by changing the strength thereof step by step. Accordingly, the assisting apparatus 10 is able to subject the patient 200 to a training image for phobia treatment, while preventing the patient 200 from having a panic attack. Note that the strength of a training image may be defined to be stronger as the resolution or tone of the training image gets higher. The strength of a training image may also be defined to be stronger as a certain image changes from the animation version to the photographed version step by step.
For example, the assisting apparatus 10 displays a predetermined training image on the display section 160 step by step, for a patient 200 suffering from a panic disorder attributed to agoraphobia. Concretely, as the first step, the assisting apparatus 10 shows a training image of an empty train to the patient 200 by displaying the same on the display section 160. Then the assisting apparatus 10 measures the physical state of the patient 200 on real time basis using the biological information measurement section 105. Next as the second step, the assisting apparatus 10 displays a training image of which the strength is increased step by step depending on the measurement result of biological information of the patient 200 measured by the biological information measurement section 105 on real time basis. For example, the assisting apparatus 10 displays on the display section 160 a training image in which the number of passengers in the train is increased step by step, for the patient 200 to look at. In this way, the assisting apparatus 10 is able to assist a patient 200 overcome his phobia, by changing the strength of a training image step by step depending on the physical state of a patient 200, and display the training image of which the strength is changed on the display section 160 to subject the patient 200 to the training image.
The training image storage section 140 stores a training image in association with a disease. Here, a training image may be an image representing a situation to which a patient 200 having a phobia such as panic syndrome feels fear or anxiety. A training image may be either a still image or a motion image. Furthermore, a training image may be a photographed version or an animation version. Furthermore, the training image storage section 140 may store a plurality of training images corresponding to the same scene but with different resolution. Specifically, the training image storage section 140 may store a plurality of training images differing in resolution from one another, such as a training image of high resolution considered as a level to which a patient 200 clearly feels fear or anxiety, a training image of low resolution considered as a level to which the patient 200 would not feel fear or anxiety so much as when the patient 200 looks at the training image of high resolution. For example, the training image storage section 140 may store, in association with a spider phobia, a training image of a photographed spider, a training image of a spider blurred in a predetermined blurring quantity a training image of a schematic spider, and a training image of an animated spider, and so on.
Additionally, the training image storage section 140 may store a three-dimensional training image to which the patient 200 would feel stronger fear, and a two-dimensional training image to which the patient 200 would not feel fear so much as when the patient 200 looks at the three-dimensional training image.
Additionally, in storing three-dimensional images, the training image storage section 140 may store a plurality of training images that pop out in different degrees from each other.
The training image storage section 140 stores, in association with a training image for a predetermined phobia, sound of a situation represented by the training image. Specifically, the training image storage section 140 stores sound that the patient 200 feels when the patient 200 is placed in a situation indicated by the training image for a predetermined phobia. For example, when storing a training image of a crowded train in association with agoraphobia, the training image storage section 140 stores sound that can be heard in a crowded train, i.e. sound of the train running, conversation between passengers, and announcement by the conductor. The training image storage section 140 also stores sound heard in a train whose passenger ratio is low. The training image storage section 140 supplies a training image to the image change control section 155 according to control by the image change control section 155. Additionally, the training image storage section 140 supplies sound associated with the training image to the sound change control section 150 according to control by the sound change control section 150.
The training image storage section 140 may store sound that feels as if the sound source is moving by using a Doppler effect, a sound effect, a change in volume, or the like. Accordingly, it becomes possible to realize a situation that the patient 200 has trouble with a realistic sense. For example, in training a patient 200 having a phobia about bees, sound feeling as if a bee is approaching the patient 200 may be stored in association with a training image with higher strength. Further, the training image storage section 140 may store sound feeling as if a bee is resting in association with a training image with lower strength.
The training image storage section 140 stores, in association with a training image for a predetermined phobia, vibration corresponding to a situation that the training image represents. Specifically, the training image storage section 140 stores vibration felt by the patient 200 when the patient 200 is placed in the situation that the training image for the predetermined phobia represents. For example, the training image storage section 140 stores vibration of a train, in case of storing a training image of a crowded train in association with agoraphobia. The training image storage section 140 supplies vibration associated with a training image to the vibration control section 156 according to control by the vibration control section 156.
In addition, the training image storage section 140 stores, in association with a training image for a predetermined phobia, pressure of a situation that the training image represents. Specifically, the training image storage section 140 stores pressure felt by the patient 200 when the patient 200 is placed in the situation that the training image for the predetermined phobia represents. For example, in case of storing a training image of a crowded train in association with agoraphobia, the training image storage section 140 stores pressure that the patient 200 undergoes when pressed by surrounding passengers while on board the crowded train. The training image storage section 140 supplies pressure associated with a training image to the pressure control section 153 according to control by the pressure control section 153.
The display section 160 displays a training image according to control by the image change control section 155. Note that such display devices as a monitor and a stereoscopic television are examples of the display section 160. The sound playback section 165 plays back sound associated with a training image displayed by the display section 160, according to control by the sound change control section 150. The assisting apparatus 10 may include a plurality of sound playback sections 165. If the assisting apparatus 10 includes a plurality of sound playback sections 165 as stated above, it becomes possible to generate more realistic sense with which a training image is displayed by the display section 160 than in a case where there is only one sound playback section 165. Accordingly, when the sound playback section 165 plays back sound associated with a training image of agoraphobia, the patient 200 can feel a sense as if he is actually on board a train. Furthermore, the display section 160 may simultaneously display a plurality of training images.
The vibration playback section 166 plays back vibration associated with a training image displayed by the display section 160, according to control by the vibration control section 156, and gives the vibration to the patient 200. For example, the vibration playback section 166 may vibrate a supporting member 1660 supporting a patient 200, thereby giving the vibration to the patient 200. To be more specific, the supporting member 1660 may be a chair on which a patient 200 is invited to sit, and the chair may be vibrated. Alternatively, the supporting member 1660 may be a floor of a room used in diagnosis of a patient 200, and the room itself may be vibrated. For example, in case of displaying a training image of a crowded train associated with agoraphobia on the display section 160, the vibration playback section 166 subjects a patient 200 to vibration of a train associated with the training image. Accordingly, the patient 200 can feel as if he is actually on board such a train.
Furthermore, the pressure playback section 163 plays back pressure associated with a training image displayed by the display section 160, according to control by the pressure control section 153, and gives the vibration to the patient 200. The pressure playback section 163 may be a cloth in which a balloon is installed for a patient 200 to wear. Alternatively, the pressure playback section 163 may be a balloon installed in a room used in diagnosis of a patient 200. In either case, it becomes possible to play back a situation to which the patient 200 has a phobia about with a more realistic sense, by pumping up the balloon to press the patient 200. For example, in case of displaying a training image of a crowded train associated with agoraphobia on the display section 160, the pressure playback section 163 gives, to the patient 200, pressure incident in a crowded train associated with the training image. Accordingly, the patient 200 can feel as if he is actually on board such a train.
The image-capturing section 100 captures an image of the patient 200 looking at a training image displayed by the display section 160. The image-capturing section 100 captures an image of a patient 200 with resolution with which an expression of the patient 200 is identifiable, resolution with which the size of the pupils of the patient 200 is identifiable, and resolution with which the motion of the patient 200 is identifiable. Further, the assisting apparatus 10 may include a plurality of image-capturing sections 100. Furthermore, the image-capturing section 100 may be a three-dimensional camera, and an omnidirectional camera. The image-capturing section 100 supplies the image of the patient 200 having been captured, to the physical state analysis section 112 within the physical state acquiring section 110. The biological information measurement section 105 measures biological information of the patient 200. Biological information of a patient 200 may be information indicating heart rate, blood pressure, breathing quantity, temperature, change quantity thereof, existence/nonexistence of perspiration, change in perspiration, and so on. The biological information measurement section 105 supplies the measured biological information to the biological information analysis section 114 within the physical state acquiring section 110.
The physical state acquiring section 110 acquires a physical state of a patient 200 looking at a training image displayed by the display section 160. Specifically, the physical state acquiring section 110 acquires a motion of the patient 200 according to analysis performed by the physical state analysis section 112 within the physical state acquiring section 110 onto an image of the patient 200 having been captured by and received from the image-capturing section 100. For example, the physical state analysis section 112 detects a motion of the patient 200, from a plurality of images that the image-capturing section 100 has captured in a predetermined time interval. Subsequently, the physical state analysis section 112 judges whether the detected motion of the patient 200 corresponds to either of predetermined motions. Here, the predetermined motions may be change in expression of a patient 200 (e.g. from a smiling expression to without expression), existence/nonexistence of blinks, the number of times of blinks, the size of pupils, a motion of turning his eyes away, a motion of closing his eyes, a body lurch, a motion of turning his face away, a motion of looking down, a tremor, etc. The judgment about whether the patient 200 is actually turning his face away may be performed for example by extracting a skin color of an area corresponding to the face of a patient 200, and examining based on the change in area size of the extracted area corresponding to the face.
Specifically, the assisting apparatus 10 displays on the display section 160 an image not intended as a training image and to which the patient 200 does not feel fear or anxiety. For example, for a patient 200 having a phobia about spiders, an image that does not contain any spider is displayed, and the image-capturing section 100 captures an image of the patient 200 while he is not feeling fear or anxiety. Subsequently, the physical state analysis section 112 analyzes the image of the patient 200 captured by the image-capturing section 100, and detects a motion of the patient 200 when he is not feeling fear or anxiety. Meanwhile, the physical state analysis section 112 receives an image in which a motion of the patient 200 is captured when a training image is displayed by the display section 160, and compares the received image with the image of the patient 200 while he is not feeling fear or anxiety. By using the comparison result, the physical state analysis section 112 acquires motions that he has taken in response to looking at the training image, from among the motions of the patient 200.
Further, the physical state analysis section 112 may acquire a change quantity per unit time of the motion of the patient 200, by analyzing an image of the patient 200 received from the image-capturing section 100. For example, the change quantity per unit time of the motion of the patient 200 may be the change quantity of the number of times of blinks per unit time of the patient 200, the change quantity per unit time of the size of the pupils, and the change quantity per unit time of the position of the line of sight, relating to the patient 200. Specifically, the physical state analysis section 112 receives an image of the patient 200 from the image-capturing section 100 for each predetermined time. The physical state analysis section 112 then analyzes each of a plurality of received images, and calculates the change quantity per unit time of the motion of the patient 200.
For example, the assisting apparatus 10 displays on the display section 160 an image not intended as a training image and to which the patient 200 would not feel fear or anxiety, for the patient 200 to look at. In this occasion, the physical state analysis section 112 analyzes an image received from the image-capturing section 100, and calculates the number of times of blinks per unit time of the patient 200. Next, the assisting apparatus 10 shows a training image to the patient 200. In this occasion, the physical state analysis section 112 analyzes the image received from the image-capturing section 100 for each predetermined time, and calculates the number of times per unit time of blinks of the patient 200 when the patient 200 feels fear or anxiety. Then the physical state analysis section 112 compares the number of times per unit time of blinks of the patient 200 when he is not feeling fear or anxiety with the number of times of blinks per unit time of the patient 200 when he is feeling fear or anxiety, and calculates the change quantity per unit time for the number of times of blinks of the patient 200. The physical state analysis section 112 supplies the acquired motion of the patient 200 and the change quantity per unit time for the motion of the patient 200, to the image change quantity extraction section 120 and the sound change quantity extraction section 125.
Then the biological information analysis section 114 within the physical state acquiring section 110 acquires the biological information of the patient 200 received from the biological information measurement section 105. For example, the assisting apparatus 10 first displays on the display section 160 an image not intended as a training image and to which the patient 200 would not feel fear or anxiety, for the patient 200 to look at. In this occasion, the biological information analysis section 114 acquires the biological information of the patient 200 received from the biological information measurement section 105, as biological information of the patient 200 when he is not feeling fear or anxiety. Next, the assisting apparatus 10 displays a training image on the display section 160. The biological information analysis section 114 compares the biological information of the patient 200 in this occasion with the biological information when the patient 200 is not feeling fear or anxiety, and acquires biological information having shown any change.
In addition, the biological information analysis section 114 acquires the change quantity per unit time of the biological information of the patient 200 measured by the biological information measurement section 105. For example, the assisting apparatus 10 first displays an image not intended as a training image and to which the patient 200 would not feel fear or anxiety, to the display section 160 for the patient 200 to look at. In this occasion, the biological information analysis section 114 analyzes the biological information of the patient 200 received from the biological information measurement section 105, and calculates biological information (e.g. heart rate) of the patient 200 per unit time. Next, the assisting apparatus 10 shows a training image to the patient 200. In this occasion, the biological information analysis section 114 analyzes the biological information of the patient 200 received from the biological information measurement section 105 for each predetermined time, and calculates the biological information per unit time of the patient 200 when the patient 200 is feeling fear or anxiety. Then the biological information analysis section 114 compares the biological information per unit time of the patient 200 when he is not feeling fear or anxiety with the biological information per unit time of the patient 200 when he is feeling fear or anxiety, and calculates the change quantity per unit time of the biological information of the patient 200. The biological information analysis section 114 supplies the acquired biological information of the patient 200 and the change quantity per unit time of the biological information of the patient 200, to the image change quantity extraction section 120 and the sound change quantity extraction section 125.
Further, the physical state acquiring section 110 supplies the motion of the patient 200 and the change quantity per unit time of the motion of the patient 200 acquired by the physical state analysis section 112, to the electronic chart storage section 170. Further, the physical state acquiring section 110 supplies the biological information of the patient 200 and the change quantity per unit time of the biological information of the patient 200 acquired by the biological information analysis section 114, to the electronic chart storage section 170. The electronic chart storage section 170 stores motion, biological information, etc. of the patient 200, in association with time. The electronic chart storage section 170 may supply a motion, biological information, etc. of the patient 200 in the past, to the physical state analysis section 112 and the biological information analysis section 114 according to control by the physical state acquiring section 110. For example, the physical state analysis section 112 may detect change in motion of the patient 200, by comparing the motion of the patient 200 in the past received from the electronic chart storage section 170 to the motion of the patient 200 obtained by analyzing an image received from the image-capturing section 100. Furthermore, the biological information analysis section 114 may compare the biological information of the patient 200 in the past received from the electronic chart storage section 170 and the biological information of the patient 200 received from the biological information measurement section 105, thereby detecting the change quantity of the biological information.
The image change quantity storage section 130 stores the change quantity of the information quantity of the training image displayed by the display section 160, in association with the physical state of the patient 200. Specifically, the image change quantity storage section 130 stores the change quantity of the information quantity of the training image displayed by the display section 160, in association with either the motion of the patient 200 being a physical state of the patient 200 or the change quantity per unit time of the motion of the patient 200. Additionally, the image change quantity storage section 130 may store the change quantity of the information quantity of the training image displayed by the display section 160, in association with either the biological information of the patient 200 being a physical state of the patient 200, or the change quantity per unit time of the biological information of the patient 200.

The pressure change quantity extraction section 123 supplies the extracted change quantity of the pressure to the pressure control section 153.
According to the change quantity of the information quantity of the training image received from the image change quantity extraction section 120, the image change control section 155 changes the information quantity of the training image displayed by the display section 160. Specifically, the image change control section 155 changes tone, resolution, dimension, the degree in which the three-dimensional image pops out, the number of training images simultaneously displayed, contrast, and the like, relating to the training image(s) displayed by the display section 160. Additionally, the image change control section 155 may change the contents of the training image displayed by the display section 160. For example, the image change control section 155 displays a non-training image on the display section 160 when not receiving the change quantity of the information quantity of the training image from the image change quantity extraction section 120. Then after a predetermined time has elapsed, the image change control section 155 extracts and displays on the display section 160 a training image that the training image storage section 140 stores in association with a disease of a patient 200. In such cases, the image change control section 155 may display on the display section 160 a training image to which the patient 200 would feel fear or anxiety last from among the training images to which the patient 200 would feel fear or anxiety. A training image to which the patient 200 would feel fear or anxiety last is for example an image of inside a train where there is no passenger, which represents a situation where there is no sound of train running or train announcement, as a training image for agoraphobia
In receiving the change quantity of the information quantity of a training image from the image change quantity extraction section 120, the image change control section 155 changes the training image according to the received change quantity of the information quantity. For example, suppose a case where the biological information measurement section 105 is measuring the change quantity of a heart rate per unit time as a physical state of the patient 200. In such a case, the biological information measurement section 105 first measures a heart rate per unit time for a patient 200 when a non-training image is displayed by the display section 160. Next, after a predetermined time has elapsed, the image change control section 155 displays a training image to which the patient 200 would feel fear or anxiety last on the display section 160. Then the biological information measurement section 105 measures a heart rate per unit time of a patient 200 in this occasion. The biological information analysis section 114 compares the heart rate per unit time of the patient 200 when he is looking at the non-training image and the heart rate per unit time of the patient 200 when he is looking at the training image, and calculates the change quantity of the heart rate per unit time.
Then the image change quantity extraction section 120 extracts the change quantity of the information quantity of a training image that the image change quantity storage section 130 stores in association with the change quantity of a heart rate per unit time calculated by the biological information analysis section 114, and supplies the same to the image change control section 155. For example, the image change quantity storage section 130 may store a larger change quantity as the change quantity of the information quantity of the training image toward a negative direction, in association with a case where the change quantity toward a positive direction of a heart rate per unit time is larger. In addition, the image change quantity storage section 130 may store a larger change quantity as the change quantity toward a positive direction of the information quantity of a training image, in association with a case where the change quantity of a heart rate per unit time toward a negative direction is larger. The image change control section 155 changes the training image stored in the training image storage section 140, according to the change quantity of the information quantity of the training image received from the image change quantity extraction section 120. The image change control section 155 controls the display section 160 to display the training image of which the information quantity has been changed. The sound change control section 150 changes the information quantity of sound played back by the sound playback section 165 according to the change quantity of sound information received from the sound change quantity extraction section 125. The sound change control section 150 controls the sound playback section 165 to play back the sound of which the information quantity has been changed.
Next, the image change control section 155 controls the display section 160 to display the training image of which the information quantity has been changed step by step. Specifically, the image change control section 155 displays the training image of which the strength has been changed to the display section 160, according to the change quantity extracted by the image change quantity extraction section 120 in accordance with the result of the physical state analysis section 112 and the biological information analysis section 114 measuring the physical state of the patient 200 on real time basis.

According to the assisting apparatus 10 according to the present embodiment, when the patient 200 is feeling strong fear or anxiety, it becomes possible to perform: shortening the display time of a training image; decreasing the combination ratio of the training image to reduce the occupation area of the training image in the display area; or decreasing the superimposing degree between the training image and a non-training image. Accordingly, it becomes possible to restrain the occurrence of the patient 200 having an attack such as panic attack, while automatically subjecting the patient 200 to a suitable training image.
For example, when the patient 200 performs the motion of closing his eyes, the fear or anxiety felt by the patient 200 is large, and so the display ratio storage section 132 may store the change quantity indicating to decrease the display time by 10 seconds in association with the motion of closing the eyes. When receiving from the display ratio extraction section 122 the change quantity of the display time stored in the display ratio storage section 132 in association with the motion of closing the eyes, the display control section 157 displays the training image on the display section 160 by decreasing the display time by 10 seconds. On the other hand, the display ratio storage section 132 may store the change quantity indicating to increase the display time by 10 seconds in association with a case where the patient 200 is smiling. Further, the display ratio storage section 132 may associate the change quantity of a predetermined combination ratio with the motion of closing the eyes. When receiving from the display ratio extraction section 122 the change quantity of the combination ratio stored in the display ratio storage section 132 in association with the motion of closing the eyes, the display control section 157 performs the display on the display section 160 by changing the combination ratio between a non-training image and a training image, according to the received change quantity of the combination ratio.
