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 observationarea 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=oWu9

TFJjHaM● 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.

Wifi Based Methods

● Wivi ○ From MIT○ Published in SIGCOMM13○ Motion Capture Behind Walls○ http://people.csail.mit.edu/

What is need for Motion Capture

• Need 8 cameras for performances• Need 3 for props• Must avoid occlusion• Input from cameras into giganet that

sends data to computer software processed input

accad

• Uses 12 Vicon cameras
