  1. Virtual Me Team:

  2. Team: Trivia • Prepared By: • MennaHamza Mohamed • Mohamed HeshamFadl • Mona Abdel Mageed El-Koussy • Yasmine Shaker Abdel Hameed • Supervised By: • Dr. MagdaFayek

  3. Agenda • Motion Capture • Tracking Techniques • Market Survey • Virtual Me • High Level Design • Time Plan • Tools

  4. Motion Capture

  5. Motion Capture • The process of translating human motion to a digital model • Games • Fast Animation • Movies • Bio Medical Analysis • VR

  6. Types of Tracking • Facial tracking • Full body tracking • Hand tracking • Partial body tracking

  7. Tracking Techniques

  8. 1- Mechanical Motion Capture • Exoskeleton, joints connected to angular encoder • Pros: • No interference, No occlusion • Real time • Large capture range • Cons: • Freedom of movement is limited • Mechanical failures

  9. 2- Magnetic Motion Capture • Magnetic sensors and a constant magnetic field generator • Pros: • No optical occlusion • Sensor orientation is directly given • Cons: • External interference • Small capture range • Wiring and batteries

  10. 3- Optical Motion Capture • Using markers (reflective or emitting) • Uses light intensity to determine marker position • Pros: • Free movement • Capture range • Cons: • Optical occlusion • Extensive pre-processing and post-processing • Controlled lighting condition

  11. 4- Marker-less Tracking • Using computer vision • Detect Humans in the picture • Uses techniques to extract motion information from the image • Silhouette detection • Joint detection

  12. Market Survey

  13. PhaseSpace • 4:24 impulse cams • 20:100 impulse active LEDs • Price: $29,950.00 to $123,950.00 • Features: • Full body motion tracking (including fingers using gloves)

  14. Nintendo Wii • Accelerometer, optical sensors • Gaming system • Price: $199 • Limitations: • Can only track the motion of the hand • Only useable with the Wii

  15. Sony PS3 Eye • Web Cam • Price: • Cam: $34.99  • Play station 3: $299.00 • Features: • Recognizes hand and body movements • Limitations: • Officially works only with Sony PS3 • Low resolution 640x480

  16. Virtual Me

  17. The Virtual Me Approach • A frame work for human motion capture • Color based markers • Arbitrary number of cams • Detect major limbs motion and orientation • Hopefully real time

  18. Sample Application • Virtual Goal • A simple game will be used as a demonstration • The player will defend his goal from multiple balls • Limited translation motion

  19. High Level Design
