Abstract
One aspect of the invention relates to an exemplary method for measuring latency of display response of a touch screen on a touch screen based device, comprising recording, by a video camera, an interaction with the touch screen, correlating, by a processor in operative communication with the video camera, data retrieved from the recording to the interaction; and determining, by the processor, a latency of the response of the touch screen to the first contact. An interaction may comprise at least a first contact between a member and the touch screen, and a response of the touch screen to the first contact, including at least a first change of a frame of a display of the touch screen.
