Stanford Reference:

05-433

Abstract

Applications

• Initially developed for biomechanical and clinical uses but can also be used for:
  • Sports performance evaluation or sports medicine
  • Animation and computer graphics
  • Digital movies
  • Interactive gaming and video games industry
  • Biofeedback and rehabilitation
  • Design and engineering
  • Ergonomics
  • Visual arts and any art using biological signals as an input or output
  • Robotics - development of biomimetic robots
  • Surveillance

Advantages

• Accurately and precisely measures three-dimensional kinematics of the dynamically moving object or human.
• Simple and time-efficient
• Markerless - No requirement for the placement of any device or object on the subject’s body
• Low cost – uses off the shelf cameras, no custom hardware required
• Many data points - Synchronizes video streams from different views that maximize the amount of information made available by the system
• Can operate in outdoor conditions and does not require a specific controlled environment
• Does not require a specific protocol set up
• Provides straightforward full body kinematics
• Broad applications
