How Kinect Works
• Compute Depth (using depth sensors)
– Structued Light Technique
– Stereo Images
• Get Body (and parts) data
– Machine Learning
– Get body parts from depth image
– Transform to skeleton

Using Kinect for Games
What you need :
• Kinect sensor device
• Kinect SDK
• Open area
– One player: Stand back 6 feet (1.8 m).
– Two players: Stand back 8 feet (2.4 m).
– Make sure that the play space is at least 6 feet (1.8 m) wide, and not wider or
longer than 12 feet (3.6 m).

14. @agatestudio@agatestudio@agatestudio
Using Kinect for Games
• Kinect SDK
– Microsoft SDK (Official for kinect)
– Open Source SDK (For other motion sensing devices :
PrimeSense, Asus Xtion, etc) : OpenNI

15. @agatestudio@agatestudio@agatestudio
Using Kinect for Games
Official SDK supports only C, C++, and Visual Basic
(Microsfot based)
Wrappers :
- AIR : AS3Kinect, as3NUI
- Unity : ZDK
- etc
