KARD contains 18 Activities. Each activity is performed 3 times by 10 different subjects.

1 Horizontal arm wave
2 High arm wave
3 Two hand wave
4 Catch Cap
5 High throw
6 Draw X
7 Draw Tick
8 Toss Paper
9 Forward Kick
10 Side Kick
11 Take Umbrella
12 Bend
13 Hand Clap
14 Walk
15 Phone Call
16 Drink
17 Sit down
18 Stand up

In total, you have 4 (files) x 18 (activities) x 3 (repetitions) x 10 (subjects), that is 2160 files.
Each filename is in the form aA_sS_eN_string where A is a two-digit actionID and S is a two-digit subjectID for the N-th repetition.

The string parameter depends on the the type of provided information:

- depthmaps.txt: depth map,
- .mp4: 640x480 RGB video,
- realworld.txt: joints position in real world coordinates,
- screen.txt: joints position in screen coordinates and depth value.

For example, the file a04_s03_e02_realworld.txt contains the skeleton joints position in real world coordinates for the second repetition of the action #4 performed by the subject #3.
The files containing the skeleton coordinates (realworld.txt and screen.txt) list the 15 joints in consecutive blocks, one for each frame.

line 1 Head
line 2 Neck
line 3 Right Shoulder
line 4 Right Elbow
line 5 Right Hand
line 6 Left Shoulder
line 7 Left Elbow
line 8 Left Hand
line 9 Torso
line 10 Right Hip
line 11 Right Knee
line 12 Right Foot
line 13 Left Hip
line 14 Left Knee
line 15 Left Foot

Each file contains 15xF lines, where F is the number of frames for that sequence, and each line reports three numbers: real world coordinates (x, y, z) for realworld.txt, or screen coordinates and depth value (u, v, depth) for screen.txt.

The dataset is made of 540 sequences for about a total of 1 hour of videos captured at a resolution of 640x480 pixels at 30fps. Uncompressed frame images are also available on request.
