measure walking activity by leveraging cell phone, gis, and widely available sensors

How much do you walk, and where do you do it?

The footstep project measures walking activity by leveraging cell phone, GIS, and sensor technologies. The philosophy is that an accurate and individual feedback is essential in addressing and improving awareness of exercise patterns.

The first-generation system targets to provide an easy to understand heat-map of walking traces, a comprehensive data histogram, and a trend-analyzer. http://footstep.cens.ucla.edu
