Abstract:
1. An apparatus configured to touch test a device having a capacitive touch interface, comprising: a plurality of touch probes; a plurality of actuators configured to move members of the plurality of touch probes to produce touches on the capacitive touch interface; a two dimensional positioning logic configured to control a two dimensional positioning apparatus to produce relative motion between the apparatus and the device in two dimensions; a camera configured to detect light associated with the capacitive touch interface; a vision system configured to provide closed loop position control for the two dimensional positioning apparatus based on light detected by the camera from the capacitive touch interface; a calibration logic configured to establish a spatial relationship between the apparatus and the device and to map a pixel co-ordinate system of the apparatus to a pixel co-ordinate system of the device to facilitate having the apparatus operate in the pixel space of the device, and a test logic configured to test the device by producing a programmed series of touches on the capacitive touch interface according to an interface test.
