Multifunction GPS embedded wrist device for runners

In this paper we represent a wearable wrist device for runners that is equipped with a GPS chip and programmable features. While running, the device would offer velocity, distance and time measurements at a glance. A button to begin and end a tagged area would also be available so that runners could mark particular parts of their run over which they wish to improve their time. The primary components of the proposed wrist device are as follows: a Microchip dsPIC 33FJ128MC802, a Sparkfun 128×128 pixel color LCD, and the LS20031 GPS chip, also available through Sparkfun. However, these components will be reviewed again and replaced with more suitable ones later.
