To attain a system and a method for control using a brain wave signal which controls electronic equipment such as a car navigation system, a robot arm combined with a mechanism, an electric wheelchair, etc. by using brain waves.
The system includes at least a brain wave sensing starting means, an alternatives graphic display means, a brain wave strength display means and a brain wave detecting means. When a push button for starting brain wave sensing which is attached to a handle or a car interior is pushed first, concerning a car, a plurality of graphics or letters showing alternatives are displayed. Thinking and choice are made by a prescribed method. The alternatives have a hierarchical structure wherein one hierarchy includes six alternatives at the maximum, and this operation is conducted a plurality of times by stages. A brain wave detecting electrode is provided at a position near a headrest (bolster) or a component hung from the ceiling. The detected brain waves are subjected to amplification and signal processing and stored, and control signals are transmitted by cable or radio.
