As touch screen interactivity has evolved in the past decade due to the introduction of capacitive technologies, so have the devices that use these screens. Higher refresh rates and the possibility of using multiple fingers simultaneously made devices more complex and the device latency harder to optimize and measure. Nowadays, it is more vital than anytime to measure the response time of a complete system.

See first-hand insights into how black-box evaluation method, based on measuring latency using a high-speed camera, was implemented in order to accurately determine touch screen response time.
