CRITICAL COORDINATION TESTER

The patent application concerns a system for determining intoxication levels by testing a subject's visual and mental alertness and physical coordination. The system includes an array of switches each having an actuator surface of a given configuration and size and a display control for sequentially identifying individual switches in a random sequence. A test subject is required within a present time interval to activate each identified switch with a stylus having an operator surface corresponding in shape to the actuator surfaces. A detector system measures the test subject's ability to activate each identified switch by properly aligning the actuator surfaces thereof with the operator surface of the stylus.
