Abstract
A system and method are disclosed for measuring latency in a device. In an embodiment, a device holder is configured to receive the device under test. A mechanical motor is configured to move a proxy device with respect to the device under test. A ground-truth measurement apparatus configured to record input proxy device movement with respect to the device under test and to record a representation of movement generated by a test application running on the device under test. A method for measuring latency includes causing a proxy device to move with respect to the device under test, recording input proxy device movement with respect to the device under test, and recording a representation of movement generated by a test application running on the device under test. Data from the recording of input proxy device movement and data from the recording of the representation of movement are used to generate latency data for the device under test.
