2. What is the Kinect?
The Kinect is a motion sensing input peripheral released by Microsoft in 2010 originally for Xbox 360.

3. Competition
The Kinect was developed to compete with the Nintendo Wii and the Playstation Eye/Move.

4. Development Kit
Microsoft provides an SDK for development on Kinect. This can be downloaded from the Microsoft website.

5. How it Works The Kinect provides four types of information: Camera
Infrared
Voice Recognition
Skeletal Tracking

6. Skeletal Tracking Example
if (playerSkeleton != null) {
Joint rightHand = playerSkeleton.Joints[JointType.HandRight];
handPosition = new Vector2((((0.5f * rightHand.Position.X) + 0.5f) * (640)), (((-0.5f * rightHand.Position.Y) + 0.5f) * (480))); }

18. Pros Voice recognition Facial recognition Doesn't require a controller
Has uses beyond gaming
Rehabilitation
Modeling
Education
Affordable Motion Capture
Troy takes over

19. Cons Not a Good Device for Authentication/Login
Imprecise Motion Capture
Requires a lot of movement room, which serves as a possible barrier to gameplay
Records you when you enter the room even in hibernation mode

Leap Motion

21. Alternatives
ASUS - Xtion

22. Other Controllers
Playstation Move

23. Playstation Move Pros Cons High precision and accuracy
Rumble feature allows for physical feedback
3D sculpting
Cons
Requires a physical controller for every player
Not as many uses outside of gaming as the Kinect

24. Other controllers
Wiimote

25. Wiimote Pros Cons Cheap Rumble feature Built-in speaker
Requires a controller for every player
Not very accurate
Limited range of motion
