Motion (for OpenNI/NITE)

NI Device Data

• In OpenNI, the Position Data of joints and the Rotation Matrix are obtained. It specifies which is used.
• By the manual of OpenNI/NITE, the Position Data has good accuracy than the Rotation Matrix.
   

Confidence

• The threshold of the confidence (reliability) of the data in OpenNI is specified.
   

Joint Constraint

• Restrictions are given and corrected to a motion of a joint and a gradual vibration of hand and foot etc.
• But this is under experimental.
   

Smoothing

• NITE Smoothing
  • A motion of joint is smoothed using the function of NITE.
  • It seems that the Moving Average is probably used. But detailed parameters are unknown.
  • It is referring to the manual of OpenNI/NITE for details (if it exists).
• Moving Average Smoothing (our implementation)
  • This uses typical Moving Average to smoothing move of joints
     

Correction

• Rotation of Y-Axis
  • This rectifies the inclination of avatar's front and back. A unit is a degree.
     

Detection of Parts

• ALL
  • The whole body is detected.
• UPPER
  • The upper body is detected.
