1. 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 an 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.

11. 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;
