Column Heading | Description |
---|---|
Sample 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 |
Time (approx) | For convenience, the date and time accurate to the nearest second. This should not be used for calculations of time diffferences |
Data Count | Count in 0.1s resolution from the start of the recording |
Event Type | 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 |
Duration | The duration of the event in seconds |
Waking Day | 0 – events during identified primary time in bed period 1 – events during identified waking day |
Cumulative Step Count | Cumulative total of all stepping events |
Activity Score | Activity score in MET.h for each event |
AbsSumDiffX | Sum of the absolute sample to sample differences on the x axis |
AbsSumDiffY | Sum of the absolute sample to sample differences on the y axis |
AbsSumDiffZ | Sum of the absolute sample to sample differences on the z axis |
Time Upright | Time in upright orientation during the event |
Time Upside Down | Time in upside down orientation during the event |
Time Back Lying | Time in back lying orientation during the event |
Time Front Lying | Time in front lying orientation during the event |
Time Left Lying | Time in left lying orientation during the event |
Time Right Lying | Time in right lying orientation during the event |
