Abstract
A system and method are disclosed for measuring latency in a device which includes a user interface that receives user input and provides output in response. In an embodiment, a body separate from the device under test is provided. A first sensor operatively attached to the body detects a touch event input to the device at a first time and a second sensor detects a response output from the device at a second time. A computational engine computes a time differential between the first time and the second time and an output outputs an indication of a measurement of latency in the device, the measurement being reflective of the time differential between the first time and the second time.
