SYMBOLIC INPUT VIA MID-AIR FINGER/THUMB MOTIONS

摘要

An information system includes primary inductance coils driven by an energy source, secondary inductance coils, a processor, a display device, and a lookup table. The processor determines an inductance value generated when coils are brought into proximal interaction with each other. The processor extracts associates alphanumeric or other symbolic information from the lookup table, and transmits the symbolic information to the display device. A circuit is also provided that generates the symbolic information for presentation via the display device, and includes an electrically-driven inductance coil positionable on a thumb of a user, passively-driven inductance coils positionable on the various phalanges of the user's fingers, the processor, and the lookup table. A method for generating and recording symbolic information includes determining the inductance value, associating the inductance value with corresponding symbolic information in the lookup table, and transmitting the symbolic information to a display device.
