Input device using elastic material
First Claim
1. An input device for keyboard input or position input based on position information comprising:
- an elastic film member;
an imaging unit which images the elastic film member from the side opposite to the user input side; and
a processor,wherein the processor detects deformation of the elastic film member based on the change in the image thereof taken by the imaging unit, and identifies the position which user pressed on the elastic film member.

Abstract
A conventional mouse and keyboard poses great load on the user'"'"'s finger and hands at key operation, and the material used for its surface is rigid. An input device which can reduce the load on the user'"'"'s finger, and gives soft touch by avoiding abrupt change in downward pressure at key operation. The input device includes elastic material on the surface, a camera to image the back surface of a key when the key is pressed, an image processor which determines finger position from the image, and an output which generates a signal according to the finger position. By using this input device, the user can carry out operations similar to those achieved by a mouse and keyboard for a computer.

6. A setting method of an input device used for keyboard input based on position information, the input device including an elastic film member, a sensor which detects the position on the elastic film member pressed by a user, a memory which stores the correspondence between a position on the elastic film member and the key, and a processor, the method comprising:
-
designating a key to the user; identifying the position of the key pressed by the user in response to the designation by using the sensor and the processor; and storing the correspondence between the key and the position in the memory; wherein the sensor is an imaging device, the elastic film member has a pattern on the surface facing to the sensor, and the processor identifies the pressed position based on the displacement of the pattern detected from the image taken by the imaging device. - View Dependent Claims (7, 8)
