Abstract
A touch panel system 1 includes: a bag-shaped touch panel body part V having a flexible touch face 11 and a visible light transmittable opposite face 12, wherein a colored fluid 20 is contained in a space between the touch face and the opposite face; a camera 50 for taking an image of the opposite face; and an image analysis part 100 for analyzing RGB values of pixels in the image captured by the camera, wherein the camera captures a change in color of the opposite face resulting from an external force applied to the touch face and making the opposite face closer in distance, moving the fluid from the location 14; and the image analysis part calculates at least coordinates of the location or shape of the location based on the RGB value analysis results, and reflects the result in an image on an image display device.
Claims20
A touch panel system, comprising:
- a touch panel body part shaped like a bag, having a touch face made of a flexible material, and an opposite face to the touch face made of a material that transmits visible light, wherein a colored fluid is contained in a space sandwiched between the touch face and the opposite face;
- a camera capable of capturing light of visible wavelengths, for taking an image of the opposite face;
- and
- an image analysis computer for analyzing RGB values of pixels in an image captured by the camera;
- the touch panel system characterized in that:
- the camera captures, when an external force is applied to the touch face, a change in a color of the opposite face resulting from the touch face and the opposite face coming closer in distance and the fluid moving from a distance-reduced location;
- and
- the image analysis computer calculates at least one of two things—coordinates of the distance-reduced location and shape of the distance-reduced location—based on RGB value analysis results of the pixels in the image captured by the camera, and reflects a result in an image on an image display device.
