Key Points
We overlay cues for turning points and travel directions on an optical see-through head-mounted display. Subjective assessments with users walking outdoors examine how clearly the system communicates directions and how much users like it.

Abstract
Would outdoor directions be easier to follow if turning points and travel directions appeared over the scene in front of us? We investigated this question using a compact, lightweight head-mounted display. This device lets users see the real world through it while information is added to their view.
We developed a navigation system that places cues for where to turn and which way to go within a walking user's field of view. We focused on users' impressions, which had not been adequately assessed in earlier development. After using the system outdoors, participants rated it through a questionnaire.
Adding these cues improved participants' ratings of how clearly they understood the turning points and travel directions. Statistical analysis supported this difference. The results also showed that the display helped users rate the outdoor navigation system more favorably.
