Abstract

New design for an infrared virtual, invisible computer keyboard and mouse for a mice and keyboard less computer is presented. The current invention uses the fact that the infrared spectrum of human fingers can be changed when irradiated with low power diodes. Using this fact, the present invention presents a method where a human finger'"'"'s infrared spectrum, irradiated by an array of infrared diodes, is picked up by infrared sensors installed either in stand alone mode, on top of the computer display or directly into the computer display. The computer then uses the finger infrared spectrums picked by the infrared sensors to created virtual, invisible mouse and keyboard where words can drawn in the air and mouse commands are also given by moving the finger in different directions in the air.

Claims

1. Design for an infrared virtual, invisible computer keyboard and mouse where a finger is irradiated by low power or infrared diodes which spectrum is picked up by infrared sensors to be able to type and give computer commands in the air.

2. Any device being electronic or not that uses finger movements irradiated by low power diodes which signal is detected by infrared sensors to give commands.
