People can be taught to control voluntarily their own alpha rhythms. This can be used to send messages in Morse code and printed out by printer when an electroencephalogram pattern is processed by an appropriate computer program. Such procedures can also be used as control signals to activate...

Claims

What is claimed is:

1. A mentally controlled optical communication system that uses volitionally altered oculomotor states to modulate an EEG control signal and activate a light transmitter, said system comprising:

a means for sensing EEG control signals from a user that has been instructed to selectively alter his alpha-wave rhythms of his brain by an eye positioning technique and produce thereby a predetermined EEG control signal pattern corresponding to a Morse code message;
a means for transmitting an optical communication signal which is activated by the EEG control signals from the sensing means; and
a receiver means which receives and displays the optical communication signal of the transmitting means.

2. A brainwave controlled optical communication process that uses volitionally altered ocularmotor states to modulate an EEG control signal and activate a light transmitter, said process comprising:

instructing a user to selectively alter his alpha-wave rhythms of his brain by an eye positioning technique; and sensing EEG control signals from the user to produce a predetermined EEG control signal pattern corresponding to a Morse code message.

3. A process as defined in claim 2, wherein the sensing step comprises:

using a plurality of electrically conductive EEG electrodes placed on the user's head and which selectively block occipital alpha rhythms to produce a 1 toggle signal when blocked and a digital 0 when alpha rhythms are unblocked to thereby send Morse code signals for communication; and
using an amplifier for sensing the differential voltage between at least two of said electrodes and selectively amplifying the electrical signals generated by said electrodes to produce thereby said predetermined EEG control signal.

4. A process, as defined in claim 3, wherein the user selectively blocks alpha rhythms by a controlled manipulation of oculomotor activities that include selective eye closure and eye position.

5. A process as defined in claim 4, wherein said oculomotor activities comprise eye elevation to cause alpha rhythms to appear and fixing eyes on a spot to cause alpha rhythm activities to stop.

6. A process as defined in claim 5, wherein said oculomotor activities comprise eye focusing and convergence to stop alpha rhythms and non-focusing and non-convergence to cause alpha rhythms.
