发明名称 VIRTUAL KEYBOARD SYSTEM
摘要 <p><P>PROBLEM TO BE SOLVED: To perform key input without a physical key and to improve operability and mounting facility. <P>SOLUTION: A light emitting part for emitting different signals is mounted to each finger of a user, a light emitted from the light emitting part is converted into voltage in proportion to illuminance of the light, and a move direction and moving distance of the finger are calculated by way of a light receiving part with a function to analyze an emitted light signal. Thus, key detection is performed and the key is displayed to the display. Also, by having a keyboard image and a finger image to be displayed to a part of the display, the user can confirm the current key input position, a move direction of the key, and a moving distance of the key. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p>
