Sway Sports Reaction Time Test
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.

Sway’s motion reaction time test has been evaluated in multiple published journal articles, showing high test-retest reliability.
Sway’s reaction time tests have been validated with high speed video cameras, the gold standard for reaction time testing. High speed camera validation demonstrates the accuracy of Sway’s motion reaction time test.
Sway Reaction Time is classified as a FDA Class II computerized cognitive assessment aid intended to provide an interpretation of the current level of cognitive function of an individual based on a battery of cognitive tasks. Sway Reaction Time does not identify the presence or absence of clinical diagnoses, and is not intended as a stand-alone or adjunctive diagnostic device. Sway Reaction Time may only be used under the supervision of a practitioner licensed by law to direct its use.
