LoL@, a Mobile Tourist Guide for UMTS

Modern lifestyle has created a new species of tourist who makes several short city trips per year and uses high-tech equipment. LoL@ (local location assistant) is a location-based multimedia UMTS (universal mobile telecommunications system) application that aims at supporting this class of tourist. LoL@ offers maps, localization, and routing functionality, and speaker-independent speech input. To stay in contact with people at home a tour diary is offered. Technical constraints like limited bandwidth, connection loss, and varying localization accuracy have to be accounted for. Although the field trials have not been completed yet, it can already be seen that map representation on smart phones with small displays is feasible.
