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 disclosed. 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.
Claims14
A control system comprising:
- at least one controlled device;
- at least one sensor for picking up bio-signals from a subject;
- and
- a controller having an input connected to said sensor, an FFT processor for converting said bio-signals into one or more control parameters, a selector having at least one device selection map, a command processor having at least one command map, and an output for sending one or more device commands to said device;
- said selector being responsive to at least one of said control parameters to generate a device selection parameter;
- said command processor being selectively responsive to said device selection parameter and to at least one of said control parameters to generate said device commands for controlling said device.
3 more elements
A controller apparatus comprising:
- an input for receiving relationship signals;
- a selector responsive to said relationship signals for selecting a subject;
- a control processor connected to said selector, having an input for receiving bio-signals from said selected subject, and having an output for providing control signals to one or more objects;
- said control processor being operative to perform fourier transform calculations on said bio-signals and mapping one or more results of said calculations to control signals.
1 more element
A control system comprising:
- a plurality of appliances;
- a first sensor for picking up bio-signals from a first subject;
- a second sensor for picking up bio-signals from a second subject;
- and
- a controller having a first input connected to said first sensor, a second input connected to said second sensor, an FFT processor for converting said bio-signals into one or more control parameters, a router, a command processor, and an output for sending one or more commands to said appliances;
- said FFT processor performs FFT calculations on said bio-signals and generates one or more control parameters;
- said router responsive to at least one of said control parameters to generate an appliance pointer for a selected one or more of said plurality of appliances;
- said command processor being responsive to said appliance pointer to choose a selected command map having a predetermined relationship with said selected one or more of said plurality of appliances and further responsive to at least one of said control parameters to generate said commands using said selected command map for controlling said selected one or more of said plurality of appliances.
