  2. Agenda • Propaganda • Current games • Exampleapplication • Real Kinectcapabilities • Structured light • SDKs • Howwould I do it

  3. Propaganda :: wow! • Controller-free gaming • Kinect responds to how you move • new type of hardware for interacting with people • Magic Disguised as Technology • Motion Sensor, SkeletalTracking, Facial Recognition, VoiceRecognition

  4. Propaganda :: prices

  11. Kinect sensor demystified :: hardware

  12. Kinect sensor demystified :: hardware

  13. Kinect sensor demystified :: hardware

  14. Structured light :: from 2D to 3D • Triangulation • Recovery of 3D information • Points • Throughtherelationshipbetweencameraandprojector (2D sources) • Twopossibilities • Ray x Plane intersection • Ray x Ray intersection

  15. Structured light :: from 2D to 3D • Codingschemes • temporal • spacial • modulated • colored

  16. Structured light :: from 2D to 3D • Codingschemes • temporal • spacial • modulated • colored

  18. Structured light :: from 2D to 3D • Codingschemes • temporal • spacial • modulated • colored

  19. SDKs :: hacksandofficial • CL NUIhttp://codelaboratories.com/nui • OpenKinecthttp://openkinect.org • OpenNIhttp://www.openni.org • Microsoft Kinect SDKhttp://research.microsoft.com/kinectsdk

  20. How I would do it :: KinectAdventures http://www.youtube.com/watch?v=xwgu7n_8RY4

  21. How I would do it :: KinectAdventures • Whatinformation do wehave? • RGB, DepthandSkeleton • Howto do it? • Skeletonmatching • Joint collision

  22. How I would do it :: KinectAdventures • Skeletonmatching

  23. How I would do it :: KinectAdventures • Joint collision . . . . . . . . . . . . . . . . . . . .

  24. Questions • Why a dot pattern? • Why a laser? • Why only one IR camera? • Is the dot pattern random? • How is it calibrated? • Why isn’t depth computed everywhere? • Would it work outside?
