Navigation system or way finding in Wearable computer help disabled and impaired persons and it is impossible to be safe and efficient for drivers as well as pedestrian. Wearable computing situation must be multi-tasking simultaneously and users need minimal attention. In this paper, we used virtual environment as real way-finding similarly. The direction cues of navigation system are investigated as visual only, visual & auditory, and visual & speech. In the paper, the trial demonstrates the difference of performance in detection of directing and performance of motor and subjective satisfaction of user.
