/**
|
|
The `ORKReactionTimeResult` class represents the result of a single successful attempt within an ORKReactionTimeStep.
|
|
|
|
The `timestamp` property is equal to the value of systemUptime (in NSProcessInfo) when the stimulus occurred.
|
|
Each entry of motion data in this file contains a time interval which may be directly compared to timestamp in order to determine the elapsed time since the stimulus.
|
|
|
|
The fileResult property references the motion data recorded from the beginning of the attempt until the threshold acceleration was reached.
|
|
Using the time taken to reach the threshold acceleration as the reaction time of a participant will yield a rather crude measurement. Rather, you should devise your own method using the data recorded to obtain an accurate approximation of the true reaction time.
|
|
|
|
A reaction time result is typically generated by the framework as the task proceeds. When the task
|
|
completes, it may be appropriate to serialize the sample for transmission to a server
|
|
or to immediately perform analysis on it.
