Abstract
A system and method of measuring the continuous latency of a touch controller is presented. According to an exemplary embodiment, the method includes generating a detection signal in response to detecting touch reports from the touch controller indicating a change in input direction; capturing a sequence of image frames, each image frame depicting a contact point on the touch screen display and indicating a state of a detection signal; and determining a difference between a time twhen an actual change in input direction occurred and a time twhen the detection signal is generated, based on the image frames.
