摘要: This paper reports on a field experiment comparing two different kinds of verbal turn instructions in the context GPS-based pedestrian navigation. The was conducted city Salzburg with 20 participants. Both instruction sets were based qualitative direction concepts. first one enhanced metric distance information and second landmark-anchored directions gathered from participants previous experiment. results show that GPS-enhanced navigation both lead to similar performance. Results also demonstrate effective voice-only guidance pedestrians unfamiliar environments at minimal error rate without stopping walk is feasible. Although performance, clearly preferred landmark-enhanced instructions.
