1. A method comprising:

  • displaying a moving item by a touchscreen device;

    receiving data that describes one or more touch inputs that are to follow the display of the moving item; and

    calculating end-to-end latency of the computing device based on the data corresponding to the one or more touch inputs and data describing the display of the moving item by at least computing a distance between a position at which the item is displayed and a position at which the touch input is received at a particular point in time, wherein the calculating involves the following expression to model the end-to-end latency;

    end-to-end latency=d/v, where d is distance and v is average velocity.
