Content of each dataset
Each dataset is made up of multiple files, with each file corresponding to a given measurement session.
The name of a given file indicates some metadata about the measurement session itselft. It is assigned based on the following template: --yrs-_--:--.csv
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.
