ABSTRACT:
An apparatus for determining a test subject's level of intoxication. Included is a display visible to the test subject and in which is produced by test equipment a pair of randomly moving, spaced apart objects. The test subject operates an actuator to indicate his selections of changing imaginary positions in the display having a predetermined constant spatial relationship to the moving objects. Dynamically determined by a computer system are the actual locations of those positions which are compared with the test subject's selections. Because of the requirement for determining imaginary positions by mental extrapolation, a very rigorous test of the subject's psychomotor capability is obtained.
