Three Udine (Italy) University researchers have melded GPS, PDAs, an accelerometer and a 3D animated personal trainer named Evita to create a handheld exercise assistant. Dubbed MOPET for Mobile Personal Exercise Trainer, the device uses 3D graphics acceleration capabilities now available on PDAs to provide users with both navigation and training support in a handheld device.

Evita, the device’s 3D animated trainer adapts fitness exercises to user’s condition and demonstrates how to correctly perform exercises using 3D animation

GPS support is used to track user positions against map references. The device provides location-aware audio and map-based navigation instructions to allow users to follow the correct path in the fitness trail.

The device also provides audio and visual feedback of user’s speed and heart rate to help users maintain intensity during their exercise sessions. Researchers plan to add a pulsoximeter as well as a function to generate and update fitness plans according to users’ goals.
