SYSTEM AND METHOD FOR MEASURING REACTION TIME OF A SUBJECT

摘要

There is provided herein a motion-based evaluation of reaction time that utilizes motion detection hardware of a mobile device to determine auditory and visual stimulated reaction time. In an embodiment, the subject holds a mobile computing device equipped with built-in triaxis accelerometer and gyroscope with both hands at arms length away from the face. A visual or auditory stimulus is then presented on screen via a software application that also records the response time for the individual to initiate a movement of the device. A simple reaction time test could include the movement of the device in any direction that exceeded a threshold of movement beyond what would be expected from static holding. An embodiment of a choice reaction time test would provide for specific directional movements as it related to an instructed stimulus.

主权项

1. A method measuring a reaction time in a subject, comprising the steps of:
a. providing a handheld motion sensor to the subject; b. presenting a stimulus to the subject at a stimulus time; c. continuously reading values from the motion sensor at least from said stimulus time until a first substantial movement of said motion sensor is read; d. determining a time of said first substantial movement; and, e. using said stimulus time, said time of said first substantial movement, and said read values from said motion sensor to determine a time of a first significant movement, thereby determining the reaction time in the subject.
