The following is a description of the file ogranization of uWave gesture library.

On the top level, each .rar file includes the gesture samples collected from one user on one day.
The .rar files are named as U$userIndex ($dayIndex).rar, where $userIndex is the index of the participant from 1 to 8, and $dayIndex is the index of the day from 1 to 7.

Inside each .rar file, there are .txt files recording the time series of acceleration of each gesture.
The .txt files are named as *$gestureIndex-$repeatIndex.txt, where $gestureIndex is the index of the gesture as in the 8-gesture vocabulary, and $repeatIndex is the index of the repitition of the same gesture pattern from 1 to 10.

In each .txt file, the first column is the x-axis acceleration, the second y-axis acceleration, and the third z-axis acceleration.
The unit of the acceleration data is G, or acceleration of gravity.
