12 Using the Kinect for Windows Adaptor
12-6
Skeletal Stream
The skeletal stream returns skeletal data using the Kinect depth device. The skeleton
frame returned contains data on the ground plane position and a time stamp. It contains
the overall position of the skeleton and the 3-D position of all 20 joints (position in
meters). Two skeletons are actively tracked, and another four are tracked passively.
Note: To understand the differences in using the Kinect adaptor compared to other
toolbox adaptors, see “Important Information About the Kinect Adaptor” on page
12-2. For information about Kinect device discovery and the use of two device IDs, see
“Detecting the Kinect Devices” on page 12-7. For an example that shows how to
access the skeletal metadata, see “Acquiring Image and Skeletal Data Using Kinect” on
page 12-9.
