Abstract
A method and apparatus are disclosed for measuring and performing real-time FFT analysis of bioelectrical signals such as (EEG and EMG) for the control of systems. Passive and active interaction with various electronic media such as video games, movies, music, virtual reality, and computer animations is also discussed. A method and apparatus for detecting the presence of a subject in a controlled area and for controlling real or virtual spaces is also disclosed.
Claims11
A control system comprising:
- at least one presence detector for detecting whether a predetermined relationship with at least one controlled space is satisfied;
- at least one device having a predetermined association with said controlled space;
- at least one sensor for picking up bio-signals from a subject;
- and
- a controller having a first input connected to said presence detector, a second input connected to said sensor, and an output for issuing one or more commands for controlling said device;
- said controller comprising a gate responsive to signals from said presence detector, said gate being in an open state responsive to said predetermined relationship being satisfied;
- said controller further comprising a FFT processor and a command map for converting said bio-signals into said commands;
- said controller being operative during said open state to issue said commands to said device.
5 more elements
A control method comprising the steps of:
- evaluating one or more predetermined relationships;
- sensing bio-signals from a selected subject;
- converting said bio-signals into one or more frequency domain control parameters;
- comparing one or more of said control parameters to a preselected control map;
- and
- generating one or more commands to control one or more aspects of an item.
