The events csv file provides the outputs of the classification algorithm as a list of time-stamped events and durations.
| Column heading | Description |
|---|---|
| Time | Date and time encoded as a floating point number, The integer part of number represents the date. The decimal portion represents the time. (Full details at: http://support.microsoft.com/kb/210276) To view the time in Excel, follow this these instructions |
| Data Count | Count in 0.1s resolution from the start of the recording |
| Interval | The duration of the event in seconds |
| Activity Code | The event type: 0 – sedentary 1 – standing 2 – stepping (Note: step events are single legged steps, and must be doubled to calculate stepping totals) With the latest classification algorithm, additional event types are available: 2.1 – cycling 3.1 – primary lying 3.2 – secondary lying 4 – non-wear 5 – seated transport |
| Cumulative Step Count | Cumulative total of all stepping events |
| Activity Score | Activity score in MET.h for each event |
| Sum(Abs(DiffX)) | Sum of the absolute sample to sample differences on the x axis |
| Sum(Abs(DiffY)) | Sum of the absolute sample to sample differences on the y axis |
| Sum(Abs(DiffZ)) | Sum of the absolute sample to sample differences on the z axis |
