- This paper describes the results of two studies conducted
to determine the role of visual cues for a collaborative
navigation task in a mixed-space environment.
Both studies required a user with an exocentric
view of a virtual room to navigate a fully immersed
user with an egocentric view to an exit. The
first study compares natural hand-based gestures, a
mouse-based interface and an audio-only technique to
determine their relative efficiency on task completion
times. The follow-up study compares natural handbased
gestures against a mouse-based interface in a
scenario in which participants are unable to communicate
verbally.
The results show that visual cue-based collaborative
navigation techniques are significantly more efficient
than an audio-only technique. The results also
show that natural hand gestures are more expressive
and lead to quicker completion times in situations
where verbal communication is not possible.
