|-
| Calibrate Kinect        
| Opens the Kinect calibration window        
| {s:atDesign}        
| Boolean        
|  
|-
| Skeleton Mode        
| Defines whether head tracking requires a body skeleton to be detected first. The skeleton mode may increase the tracking accuracy but demands a body in a frame, which is not a case for short distances.        
| {s:atNormal}        
| Boolean        
|  
|-
| Distant Mode        
| Defines whether head tracking is operates in the distant mode, with the optimal range between 0.8 to 4 meters. If false, the near mode will be used, with the optimal range between 0.4 and 3 meters. The X-Box Kinect devices ignore this property because they can operate only in the distant mode        
| {s:atNormal}        
| Boolean        
|  
|-
| Color Image Format        
| Defines a format for the color images obtained from a Kinect sensor        
| {s:atDesign}        
| ColorI..        
|  
|-
| Depth Image Format        
| Defines whether head tracking is operates in the distant mode, with the optimal range between 0.8 to 4 meters. If false, the near mode will be used, with the optimal range between 0.4 and 3 meters. The X-Box Kinect devices ignore this property because they can operate only in the distant mode        
| {s:atDesign}

| Triggering Mode        
| Defines the work program for the element.        
| {s:atDesign}        
| stTarg..        
|  
|-
| Fixation Duration        
| When the triggering mode is fixation, the property defines the duration (in ms) of the time interval in which fixation of head position/vector is required.        
| {s:atNormal}        
| clTime        
|  
|-
| colspan="5" bgcolor="#AADDDDD" | Head Position
|-
| Position Validation        
| Defines whether the head position is validated to the bounding sphere at runtime        
| {s:atNormal}        
| Boolean        
|  
|-
| Bounding Center        
| Defines the center of the valid bounding sphere for the head position (in meters)        
| {s:atNormal}        
| Point3D        
|  
|-
| Bounding Radius        
| Defines the radius of the valid bounding sphere for the head position (in meters)        
| {s:atNormal}        
| Double        
|  
|-
| colspan="5" bgcolor="#AADDDDD" | Head Vector
|-
| Vector Validation        
| Defines whether the head vector is validated to the predefined ranges at runtime        
| {s:atNormal}        
| Boolean        
|  
|-
| Roll Range        
| Defines the valid range for the head roll angle

| Pitch Range        
| Defines the valid range for the head pitch angle        
| {s:atNormal}

|-
| Newest Sample        
| Returns the tracking sample

|-
| Is Head Detected        
| Indicates whether the head is detected in the current tracking        
| {s:atStatus}        
| Boolean        
|  
|-
| Is Valid Head Vector        
| Indicates whether the current head vector is valid across all defined ranges of head angles        
| {s:atStatus}        
| Boolean        
|  
|-
| Is Valid Head Position        
| Indicates whether the current head position is within the defined bounding sphere        
| {s:atStatus}        
| Boolean        
|  
|-
| Current Status        
| Returns a text line describing the current status of head tracking        
| {s:atStatus}        
| String        
|  
|-
| colspan="5" bgcolor="#AADDDDD" | Runtime Status
|-
| Is Triggered        
| Indicates that the element has been triggered by end of the playback at least once, since the onset of the parent event.        
| {s:atNormal}        
| Boolean        
|  
|-
| Triggering Time        
| Indicates the latest event time when the element was triggered (in ms elapsed since the onset of the parent event)

|-
| Frame Rate        
| Returns the current framerate of head tracking (times/sec)
