We present a description and an evaluation of the interface for the TrekWizard, a tool that adds value to raw location information available to trekkers from the GPS system. The interface has a novel component for providing distance and time readouts, including ETA (Estimated Time of Arrival) and ETT (Estimated Time to Travel) information.
