Data Structure – Vicon data

Subjects Motions (6 types)

Angles (11 joints)

Trial 1 Trial 2 Trial 3 Trial4 Trial 5

Important! - Take 5 trials from the last column- Sampling rate is 120Hz- Sampling rates of Kinect and

Vicon data are different

Do not use

Raw ‘*.mat’ file - Kinect data

Sampling rate is not constant , check Time stamp (20 ~ 30Hz)

If Kinect fails to respond, the size of ‘mat’ file is zero.
