Abstract
A computer interface device for a coordinate measuring machine comprises a trackball that transmits perpendicular movement signals to a computer in response to corresponding perpendicular tangential movement of the trackball. The computer is interconnected with the coordinate measuring machine and normally receives measurement data corresponding to a location of a probe on the computer. The trackball is located adjacent the probe so that a user grasping the probe can manipulate the trackball to transmit data manipulation signals to the computer. Typically, the trackball moves a cursor about the computer screen. A plurality of data entry buttons are included on the interface device and enable the user to execute computer procedures selected by the cursor.
