Visual training device and visual training method
First Claim
1. A visual training device, which training includes changing a line of vision and looking to areas adjacent a visual point, comprising:
- a screen arranged facing a subject with a visual impairment and visible to a third party;
a line of vision detection unit that detects the line of vision of the subject and outputs line of vision signals indicating the line of vision;
a visual field data storage unit that stores visual field data indicating a specific visible area that the subject can see completely and a specific area of visual impairment that the subject cannot see completely or partially;
a response signal receiving unit that receives response signals indicating the response from the subject viewing the screen; and
a screen control unit that displays on the screen a specific image for visual training in the specific visible area and prevents the display of an image in the specific area of visual impairment, the screen control unit moving the specific visible area based on the visual field data in correspondence to the movement of the line of vision of the subject specified by the line of vision signals, wherein the screen control unit enables the third party to view the specific image for visual training in the specific visible area and to view the area of visual impairment superimposed over the specific image,wherein the screen control unit displays on the screen the specific image represented in a virtual space where the specific image imitates an actual scene that the subject would experience in real life, the virtual scene image is moved corresponding to the response signals relating to the directional indications received by the response signal receiving unit from the subject, and the subject is allowed a pseudo-moving experience within the visual space while the third party simultaneously views the relationship of the specific image and the area of visual impairment.

Abstract
A visual training device 1 including: a screen arranged facing a subject H having visual impairment; a line of vision detection unit that detects a line of vision of the subject H and outputs line of vision signals indicating the line of vision; a visual field data storage unit that stores visual field data indicating the visible area AR2 and the area of visual impairment AR1 of the subject H; and a screen control unit 53 that, on the aforementioned screen, moves the visible area AR2 specified based on the aforementioned visual field data in correspondence to the movement of the line of vision of the subject H specified by the aforementioned line of vision signals. The display format of the visible area AR2 or a region including the vicinity thereof, is displayed different from the display format of the other region. By doing this, an attitudinal barrier of the person with visual impairment, the subject, can be removed, and the visual training device can allow easy training to be provided.

4. A visual training method, which training includes changing a line of vision and looking to areas adjacent a visual point, comprising:
-
arranging a screen facing a subject with a visual impairment and visible to a third party; detecting the line of vision of the subject via a line of vision detection unit; storing in a visual field data storage unit set up in a specified region of memory, visual field data indicating a specific visible area that the subject can see completely and a specific area of visual impairment in the visual field of the subject that the subject cannot see completely or partially; using a computer to receive response signals indicating the response from the subject viewing the screen; using a computer to display on the screen a specific image for visual training in the specific visible area and preventing the display of an image in the specific area of visual impairment, move on the screen the visible area specified based on the visual field data in correspondence to the selection of behavior or movement of the line of vision of the subject specified by the line of vision signals output from the line of vision detection unit, and to enable a third party to view the specific image for visual training in the specific visible area and to view the area of visual impairment; and using the computer to display on the screen the specific image represented in a virtual space where the specific image imitates an actual scene that the subject would experience in real life, the virtual scene image is moved corresponding to the response signals relating to the directional indications received by the response signal receiving unit from the subject, and the subject is allowed a pseudo-moving experience within the visual space while the third party simultaneously views the relationship of the specific image and the area of visual impairment. - View Dependent Claims (5, 6, 7, 8)

9. A visual improvement training device for subjects with limited fields of vision, which training includes changing a line of vision and looking to areas adjacent a visual point, comprising:
-
an image generating unit for providing images that can be viewed by a subject and a third party; a line of vision detection unit to monitor an eye of the subject and provide signals indicative of the subject'"'"'s line of vision relative to images viewed by the subject from the image generating unit; a visual field data storage unit that stores visual field data including a first area indicating a specific visible area that the subject can see completely and a second area indicating a specific visual impairment field that the subject cannot see completely or partially; a control unit that receives the signals indicative of the subject'"'"'s line of vision and controls the image generating unit to provide specific images for visual training in the first area, and preventing the display of images in the second area from the visual field data storage unit in correspondence to the movement of the line of vision signals, the control unit also enabling a third party to view the first area and the second area, and displays on the screen the specific image represented in a virtual space where the specific image imitates an actual scene that the subject would experience in real life, wherein the virtual scene image is moved corresponding to the response signals relating to the directional indications received by the response signal receiving unit from the subject, and the subject is allowed a pseudo-moving experience within the visual space while the third party simultaneously views the relationship of the specific image and the area of visual impairment; and an input control member to enable the subject to change the images provided by the image generating unit to provide a pseudo moving experience within a virtual space.
