Response speed and accuracy measurement device

Claim 1

A response speed and accuracy measurement device, comprising, a random number generator operative to generate an at least quasi-random multidigit code of digits selected from numeric characters, alphabetic characters and other symbols, an output means including a display operative to display said code, a start switch operatively associated with said random number generator and display and actuatable to cause said multidigit code to be generated and displayed on said display, a keyboard comprising a plurality of data entry keys by which an operator may enter the generated code, means for limiting the time duration of said generated code on said display in response to operation of said start switch to one second or less to thereby remove the generated code from said display prior to the operator's entry of the generated code by memory, timer means for measuring the response time for an operator to enter the generated code by said keyboard, said response time beginning upon actuation of said start switch and ending upon actuation of the last of a number of data entry keys equal to the number of digits in said multidigit code whereby said response time tests the speed of both memory and physical response, check means for comparing the code entered by an operator to the generated code and for detecting a match of said codes and said output means being operatively connected to said timer means and check means for indicating the operator's response time and whether a match was detected by said check means.
