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

4

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

6 Facial tracking Full body tracking Hand tracking Partial body tracking

7

8 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 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 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 Using computer vision Detect Humans in the picture Uses techniques to extract motion information from the image Silhouette detection Joint detection

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

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

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