Abstract

By presenting continuously updated heading and distance information on a small head-mounted display, as a supplement to a GPS-receiver, the authors examined if workload could be reduced and performance increased when navigating in a demanding situation. The purpose was to present as limited, but sufficient, information as possible to facilitate navigation. The technique was tested on ground troops, but could also be used by rescue services and police in situations that require navigation in unknown environments. The main findings were that the workload was reduced in two aspects (during navigation and handling personal equipment) but increased in another (looking for foot placement). When using the head mounted display, it was found that participants stopped fewer times to look at the GPS-receiver if they had continuous updated heading and distance information. This suggests that a supplement with minimal information on a head mounted display could be useful when navigating with a GPS-receiver in an unknown environment.
