Claim of US Patent No. 10,362,977

1. A method of measuring a reaction time in a subject, comprising the steps of:a. providing a handheld device to the subject, said handheld device having a motion sensor and a CPU integral thereto, wherein said CPU is in electronic communication with the motion sensor;
b. presenting a stimulus to the subject at a stimulus time after a selected random period of delay;
c. within the handheld device,
(c1) using said CPU to continuously read values from the motion sensor at least from said stimulus time until one or more of said continuously read motion values corresponds to an acceleration value greater than or equal to 0.1 g, thereby determining a time of a first substantial movement;
(c2) using said stimulus time, said time of said first substantial movement, and said continuously read motion values from said motion sensor to determine a time of a first significant movement that is earlier than said time of said first substantial movement, thereby determining the reaction time in the subject, wherein said time of said first significant movement is determined by:
(i) searching through said continuously read motion values in reverse order from said substantial movement time toward said stimulus time to find a first instance where, as between two adjacent continuously read motion values, an earlier measured one of said two adjacent continuously read motion values is greater than a later one of said two adjacent continuously read motion values, thereby determining a first significant movement, and
(ii) determining the reaction time of the subject to be a time of the first significant movement, and
(c3) using said CPU to report said reaction time of the subject.
