  • Patent number: 4978303
    Abstract: An apparatus for generating non-personalized and personalized test scores. Characters are displayed on a display of a housing containing a microprocessor and means for driving the display. A keyboard is provided on the housing, whereby the user of the device may match a cursor on the display with each of the displayed characters, with the number of actions taken by the user, the time of response, and the number of correct and incorrect responses by the user being used to generate a score. The score may be used for comparison with later scores of the same user, who is identified by an individualized code stored in the microprocessor. The date and time of the most recent test for the given user may also be stored in the microprocessor. A test may be taken which is not to be compared with any other test results, in the non-personalized embodiment. Pass and fail displays are provided, to generate a pass or fail result depending upon the user's score compared with his earlier score or with a standardized score.
