Evaluation of Automated Systems for Assessing Physical Activity in Specific Environments

FUNDING SOURCE: Active Living Research, Robert Wood Johnson Foundation

TIMELINE: December 2002 - May 2005

PRINCIPAL INVESTIGATOR: Patricia Sharpe, PhD, MPH (USC PRC)

This project involves the development of an automated system for monitoring the use of indoor and outdoor facilities for physical activity and to assess the validity and reliability of the system. The monitoring system that will be developed, field tested, and refined is based on a complementary metal oxide semiconductor (CMOS) image acquisition sensor that addresses the weaknesses of existing automated systems. Documentation will be placed in the public domain.
