What is Reaction Time?

Reaction time is a measure of how quickly you can identify a signal and produce a response. Reaction time is an analysis sensory and neuromotor function that encompasses stimulus recognition and processing, followed by the initiation of a neuromotor response.

Motion Reaction Time

Sway’s proprietary algorithms measure reaction time in response to a user’s movement of a mobile device. The built-in motion sensors of the mobile device assist in identifying the earliest intentional movement as a response to a stimulus. Sway’s Simple Reaction Time is a significant step in bringing accurate cognitive testing to a mobile device.

Touch Reaction Time

Cognitive testing on a mobile device typically replaces the keyboard or mouse in computerized models with the touch screen of a tablet or mobile phone. Mobile devices use projected-capacitive touch screens, which detect touch through a cyclical “searching” for a touch event. This presents concerns over consistency across devices and variable latency cycles depending on when the touch event occurred in the cycle.
