PATENT 6024700

A method of detecting a thought and generating a control instruction
corresponding to the thought includes detecting the thought by
monitoring air pressure near a human ear when a user is thinking. In
addition, the method includes providing a control instruction
corresponding to the detected thought. A system for detecting a
thought and generating a control instruction corresponding to the
thought is also disclosed and includes a pressure sensor for sensing
a pressure near a human ear when a user is thinking, wherein the
sensor produces an electrical signal corresponding to the pressure. A
processor processes the electrical signal to detect the thought,
generates the control instruction in response to the detection, and
sends a control instruction to an output peripheral which provides an
output control function corresponding to the control instruction.
