Wearlab Beach Volleyball Serves and Games

The dataset comprises data from 10 users in 4 sessions of 4 players each (2 players were present in two sessions). The data were recorded using 4 BlueSense [1] inertial platforms per user. The sensors were placed on the torso, and on each segment of the dominant arm (i.e. upper arm, lower arm and hand).

The players were asked to perform 12 repetition of 4 type of serves, i.e. long float, long top spin, short float and short top spin. After the completion of the 48 serves (12 serves x 4 types), the players were asked to play freely in 2-vs-2 games, following the standard beach volleyball rules.

The dataset include one file per user per session. In the file, the data are formatted in single .txt files for every user. - Each file contains 54 columns:

• 1 timestamp in milliseconds
• 13 x 4 body position (torso, upper_arm, lower_arm, hand):
• 9 for sensor data
• 3 x accelerometer
• 3 x gyroscope
• 3 x magnetometer
• 4 for quaternion format of orientation data (w, x, y, z)
• 1 for the activity label ID:
• 1001 Long float serve
• 1002 Long top spin serve
• 1003 Short float serve
• 1004 Short top spin serve
