Abstract

A multifunction wristwear device includes a distance tracking device to calculate the total distance traveled by the wearer during an event by using GPS signals. The distance tracking device automatically adjusts the sampling rate to compensate for blockage of GPS satellites and changes in direction so as to provide the optimal accuracy given the available battery power. The device can provide useful information to the wearer during and after the event through a menu-driven interface on a matrix-type display screen.
