1. An apparatus for performing machine control functions by the use of the machine operator'"'"'s eye movements comprising:
- a radiation source means, aimed in the approximate direction of the operator'"'"'s eye;
a radiation sensor means, placed in proximity to the radiation source means, activated by radiation reflected from the operator'"'"'s eye, and producing an electrical signal dependent upon the existence of reflections from the operator'"'"'s eye;
a command discriminator means electrically connected to and receiving an input signal from the radiation sensor means comprising;
1. control and logic circuit means, connected to and receiving the input signal from the radiation sensor means, counting the number of interruptions of the input signal;
2. interpreter means, connected to and receiving a signal from the control and logic circuit means, providing electrical signals to the various following sections of the command discriminator depending upon the number of interruptions counted by the control and logic circuit means;
3. sequencer start control means connected to and receiving a signal from the interpreter means, producing a control signal and sending that signal to an automatic sequencer means to start an automatic sequencing action;

Abstract
A machine and telephone controller for complex machine functions which is operated by simply looking at it and winking the eye in a preset code. Photocell and electronic logic circuitry stop a sequencing digital display at the desired numerals and activates the machine or telephone for the displayed number which may indicate either a function of a machine or a telephone number to be dialed.

11. A method of performing machine control functions by the use of an operator'"'"'s eye movements comprising:
-
aiming a radiation source in the direction of an operator'"'"'s eye; capturing the reflection of the radiation from the operator'"'"'s eye with a radiation sensor sensitive to the radiation of the radiation source which generates an electrical signal dependent upon the presence or absence of reflected radiation; counting the interruptions in the electrical signal generated by the radiation sensor; controlling several functions of a digital display and a sequencing device for the digital display by matching the count of interruptions against a previously selected code for the control of each of the several functions; and operating a machine controller by matching a digit displayed upon the digital display at the time a particular number of interruptions is counted, to a digit representing a specific action by a controlled machine.
