Data sources

For each datasource the following table is fulfilled:

Name

Acceleration data gathered from Android phone

Description of the information measured

Y axis accelerometer data

L2 Norm of accelerometer data : sqrt(x^2 + y^2 + z^2)

Units

Acceleration (m/s2)

Example values

9.918428421020508 m/s2

Frequency of generated data in operation

Acceleration rate is generated with the setting SENSOR_DELAY_FASTEST that get sensor data as fast as possible (~5ms).

 

Name

Received Signal Strength from wireless sensor network installed at the test site.

Description of the information measured

Mean and Standard Deviation values of Received Signal Strength (RSS) of each tag provided by the Crossbow IRIS tags

Units

RSSI (RSS Index)

Example values

Mean: 15.75 - Standard Deviation: 2.4874685

Frequency of generated data in operation

RSSI mean and standard deviation rate is generated every 250ms


DataSets

After, for instance, 30 minutes operation the competitor generates the following data sets:

3 text files with the following information separated by white spaces:

  • inputFromWSN.txt
    • timestamp MEAN_RSSI_12 SD_RSSI_12 MEAN_RSSI_13 SD_RSSI_13 MEAN_RSSI_23 SD_RSSI_23 MEAN_RSSI_14 SD_RSSI_24
    • where the indexes i and j represent the tag id  (MEAN_RSSI_IJ SD_RSSI_IJ), so ij is the reciprocal value
    • i=1 -> left ankle; i=2 -> right ankle; i=3 -> chest; i=4 -> cyclette
  • L2NormAccelerationVector.txt
    • timestamp L2NormAccelerationValue
  • YGravity.txt
    • timestamp AccelerationYValue

Files:

-        inputFromWSN.txt

-        L2NormAccelerationVector.txt

-        YGravity.txt
