Motion Capture Emilio Cantu, Jin He, Gerard Louis, Brian Orchosky, Chelsey Salberg
Challenges and New Techniques • Expense • Hardware • Software • More Sensing Methods
Expense • Very expensive • Vicon • Complete Vicon MX40 Motion Capture System - $220,000
Hardware and software • Hardware • Real time • High frame rate • High bandwidth • Software • Image processing algorithms • Extract the target image from its background
New Methods • IR Camera Based • Leap Motion • Electrical signal based • MYO • Wifi Based • WiSee • Wivi
Leap Motion • Human computer interaction • Hand and finger motion • Smaller observation area and higher resolution • 2 IR cameras and 3 IR LEDs • Provide SDK, C++ • App store - new • https://www.leapmotion.com/
MYO • Wristband • Electrical activity in muscles. • https://www.youtube.com/watch?v=oWu9TFJjHaM • Wirelessly control computer. • Interact with digital world.
Wifi Based Methods • Wisee • From Univ of Washington • Published in MobiCom13 • http://wisee.cs.washington.edu/ • Classify a set of 9 gestures • Achieve 94% accuracy.
