Abstract
An exemplary system for verifying DPI values of computer mice is disclosed. The system comprises: a stepper motor connected with a horizontal servo axle and controlling the horizontal servo axle to perform back and forth movements which drives the computer mice to move in a straight line back and forth; a computer configured for receiving measurement parameters, for sending move instructions to the stepper motor, for recording initial coordinates of a computer pointer of the computer mice and current coordinates of the mouse pointers of the computer mice, and calculating DPI values according to the initial coordinates and the current coordinates; and a servo controller electrically connected between the computer and the stepper motor for sending impulse control signals to control operations of the stepper motor. A related method is also disclosed.
