Data sources
For each datasource the following table is fulfilled:
|
Name
|
3-axis acceleration for chest and thigh accelerometers
|
|
Description of the information measured
|
sensor acceleration provided by 2 accelerometers placed on the chest and the right thigh
|
|
Units
|
Acceleration (m/s2)
|
|
Example values
|
9.2 m/s2
|
|
Frequency of generated data in operation
|
Acceleration is generated every 20ms (approximately). It is not a constant rate, therefore the timestamp should be used to estimate the exact difference between two consecutive samples.
|
DataSets
After, for instance, 30 minutes operation the competitor generates the following data sets:
-
An array of arrays that include:
[time, accelerationValueChest_x, accelerationValueChest_y, accelerationValueChest_z, accelerationValueThigh_x, accelerationValueThigh_y, accelerationValueThigh_z]
every 20ms (approximately).
An array of arrays that include: [time, accelerationValueChest_x, accelerationValueChest_y, accelerationValueChest_z, accelerationValueThigh_x, accelerationValueThigh_y, accelerationValueThigh_z]every 20ms (approximately).
Files:
- A file containing this sample in .txt format.
