It is assigned based on the following template: &lt;UserId&gt;-&lt;Gender&gt;-&lt;Age&gt;yrs-&lt;SignalLength&gt;_&lt;Year&gt;-&lt;Month&gt;-&lt;Day&gt;_&lt;Hour&gt;-&lt;Minute&gt;-&lt;Seconds&gt;.csv</p> <p>The content of the file itself corresponds to the sensor readings collected during the measurement session. It is a collection of timestamped sensor values, reported in a comma-separated format. The first column represent the timestamp of the sensor event (in nanoseconds), the second one the type of the considered sensor and the 3 following ones the actual values along the different axis. Please refer to the official Android SensorEvent documentation for more details.</p>
