Webcams and Crowdsourcing: 2014-2016
Project Dates: 2014-2016
This project is a novel, interdisciplinary collaboration between public health and computer science to improve surveillance and evaluation of physical activity patterns and associated built environment characteristics.
Specifically, the project examines innovative strategies to develop a real-time, non-labor intensive assessment of physical activity and built environment characteristics by capitalizing on webcams continually taking photographs of outdoor spaces.
The Media and Machines Laboratory of Dr. Robert Pless developed and maintains the Archive of Many Outdoor Scenes (AMOS) that has collected over 325 million images of outdoor environments from more than 23,000 web cameras (webcams) since 2006. Every identified, outdoor, publicly-available on the Internet webcam is added to the AMOS dataset with an image taken and archived each half hour from the webcam thereafter. AMOS continues to expand with new webcams and newly captured images. Scenes include street intersections, plazas, parks, and school playgrounds.
- Develop and test the reliability of using publicly available, outdoor webcams to enumerate built environment characteristics and physical activity patterns across thousands of global outdoor environments.
- Develop and test the reliability and validity of using crowd-sourcing to enumerate built environment characteristics and physical activity patterns across thousands of global outdoor environments.
Implications for Research and Practice
Results will yield actionable knowledge regarding the use of webcams and crowd-sourcing to increase by orders of magnitude the amount and quality of global recorded measurements of physical patterns and built environments. This type of consistent and up-to-date surveillance has wide-ranging applicability from community to international obesity prevention evaluation.
