The Kinect CHOP reads positional and skeletal tracking data from the Kinect and Kinect2 sensors. Up to 6 people's full skeletons can be tracked (2 on the original Kinect), and the center position of an addition 4 people in the camera view is tracked as well. Multiple Kinect devices can be used by using multiple Kinect CHOPs and changing the Camera parameter.
It also supports face tracking.
NOTE: This CHOP is only supported on Windows OS with the Kinect for Windows hardware and the Kinect 2, not Kinect for Xbox hardware.
To use a Kinect 2 device you need to install the Kinect 2 SDK or runtime from here.
To use the original Kinect 1 you will need to install the Kinect Runtime 1.8 for builds greater than 12000, or Kinect Runtime 1.7 for builds below 12000. Multiple Kinects: The Kinect 2 SDK does not allow for multiple kinects to be used on one system at a time. There is no way to connect to different devices through the SDK. The Kinect 1 can do this, but not the 2.
Parameters - Kinect Page
active - When 'On' data is captured from the Kinect sensor.
hwversion - ⊞ - Choose between Kinect v1 or Kinect v2 sensors.
- Version 1
- Version 2
sensor - Selects which Kinect sensor to use. Only available when using Kinect v1.
skeleton - ⊞ - Selects options for skeletal tracking.
full- Track full skeleton.
seated- Track seated skeleton.
off- Do not track skeleton.
maxplayers - Limits how many players to track.
interactions - Enables interactions, which returns interaction data such as "grip" and "press". The additional channels output are prefixed with
- For the x and y values of the interaction hand, 0.0 corresponds to left edge of interaction region and 1.0 corresponds to right edge of interaction region, but values could be outside of this range.
- For the z value of the interaction hand, 0.0 means that hand is close to shoulder and 1.0 represents a fully extended arm, but values could be outside of this range.
NOTE: Interaction mode requires a depth resolution of 640x480. As such, a Kinect TOP displaying a depth image for the same sensor will output an image with a resolution of 640x480 and the Near Depth Mode setting will be set in the Kinect CHOP.

Relative Bone Rotations
relbonerotations - Returns rx, ry, and rz relative rotation channels for each bone. The rotation is relative to the previous joint.
Absolute Bone Rotations
absbonerotations - Returns rx, ry, and rz absolute rotation channels for each bone.
bonelengths - Returns the length for each bone.
Unroll Bone Values
unrollbones - Return the rx, ry, and rz values in a form that includes no discontinuities (or wrap arounds), so that they can be safely blended, filtered, lagged etc. For example, a rotation value running from 0 to 360 continuously, unrolled would start at 0 and increase in value indefinitely.
World Space Positions
worldspace - Returns the tracked positions in world space coordinates. For each tracked point, a
tz triplet of channels will be output.
Color Space Positions
colorspace - Returns the tracked positions in image space coordinates. On the Kinect 2 this is relative to the color image, on the Kinect 1 it is relative to the depth image. For each tracked point, a
tz triplet of channels will be output.
Depth Space Positions
facetracking - Returns face tracking channels for detected faces.
statuschans - A number of additional status channels are reported when this is turned on. A group of channels will report if a joint is currently being tracked, and another group of channels reports if part of the player is clipped outside the bounds of the Kinect sensor. The additional channels output are suffixed with
Near Depth Mode
neardepthmode - Enables near mode for skeleton tracking, which allows the depth camera to see objects as close as 40cm to the camera (instead of the default 80cm).

Parameters - Smoothing Page
smoothing - Increasing the smoothing parameter value leads to more highly-smoothed skeleton position values being returned. It is the nature of smoothing that, as the smoothing value is increased, responsiveness to the raw data decreases. Thus, increased smoothing leads to increased latency in the returned skeleton values. Values must be in the range 0 through 1.0. Passing 0 causes the raw data to be returned.
correction - Lower values are slower to correct towards the raw data and appear smoother, while higher values will correct toward the raw data more quickly. Values must be in the range 0 through 1.0.
prediction - The number of frames to predict into the future. Values must be greater than or equal to zero. Values greater than 0.5 will likely lead to overshooting when moving quickly. This effect can be damped by using small values of Max Deviation Radius.
jitterrad - The radius in meters for jitter reduction. Any jitter beyond this radius is clamped to the radius.
Max Deviation Radius
maxdevrad - The maximum radius in meters that filtered positions are allowed to deviate from raw data. Filtered values that would be more than this radius from the raw data are clamped at this distance, in the direction of the filtered value.
Parameters - Common Page
timeslice - Turning this on forces the channels to be "Time Sliced". A Time Slice is the time between the last cook frame and the current cook frame.
scope - To determine which channels get affected, some CHOPs use a Scope string on the Common page.
Sample Rate Match
srselect - ⊞ - Handle cases where multiple input CHOPs' sample rates are different. When Resampling occurs, the curves are interpolated according to the Interpolation Method Option, or "Linear" if the Interpolate Options are not available.
- Resample At First Input's Rate
first- Use rate of first input to resample others.
- Resample At Maximum Rate
max- Resample to the highest sample rate.
- Resample At Minimum Rate
min- Resample to the lowest sample rate.
- Error If Rates Differ
err- Doesn't accept conflicting sample rates.
exportmethod - ⊞ - This will determine how to connect the CHOP channel to the parameter. Refer to the Export article for more information.
- DAT Table by Index
datindex- Uses the docked DAT table and references the channel via the index of the channel in the CHOP.
- DAT Table by Name
datname- Uses the docked DAT table and references the channel via the name of the channel in the CHOP.
- Channel Name is Path:Parameter
autoname- The channel is the full destination of where to export to, such has
autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is Path:Parameter are relative to.
exporttable - The DAT used to hold the export information when using the DAT Table Export Methods (See above).
