An iPhone application developed by a University of Houston computer science professor is being featured on television again, this time on KUHT Houston PBS.

A one minute segment about the Walk’n’Play exercise app, developed by Ioannis Pavlidis, Eckhard Pfeiffer Professor of Computer Science. Available for free from Apple’s “App Store,” it allows users to keep track of their physical activity and compete with other users.

The one minute segment on the Walk’n’Play app will air during programming breaks. Is part of the UH Moment series, a segment that began on KUHF radio and has now expanded to Houston’s public television.

You can watch the KUHT segment here.

The Walk n’ Play app tallies a users’ every movement over the course of a day, including walking and climbing stairs, and translates it into calories burned.  The game gives an accurate calorie count thanks to a biomedical calibration process applied on the iPhone’s accelerometer that senses motion and can be made to measure metabolic activity. The method was developed in the UH Computational Physiology Lab and lauded in peer-reviewed publications.

More than 10,000 users have downloaded the app so far.

The app was also recently featured in February in a Houston television news story, which you can view here.
