EEG Biofeedback Kit

The problem with various devices controlled by brainwaves is that we have no idea what sort of brainwaves we are generating. We can perceive only the internal states they generate. It is like a blind person making sculpture - the artist knows how the work feels but cannot tell how it looks.

EEG machines are huge, fearfully primitive looking affairs. Most are clearly relics from the 1970s. I propose a small, modern home EEG machine with a limited number of leads and a visual readout (rather than a long strip of paper). The readout would display a shape, number, or some other visual cue corresponding with the detected signals.

Once it is possible to perceive what the machine detects, we can start developing mind control for electronics. Imagine there is a transient pattern you notice coming up on the readout. Using biofeedback, you could train yourself to think so as to hold that pattern for a full second. Now a remote control hooked up to the home EEG machine could be programmed to do a task (eg: flip the channel) when the given pattern appears and is held for a full second.

This type of interface would be great for a motorized wheelchair used by a quadriplegic.
