In this research, we explore how different types of augmented gesture
communication cues can be used under different view sharing techniques in a
remote collaboration system. In a pilot study, we compared four conditions:
(1) Pointers on Still Image, (2) Pointers on Live Video, (3) Annotation on
Still Image, and (4) Annotation on Live Video. Through this study, we found
three results. First, users collaborate more efficiently using annotation
cues than pointer cues for communicating object position and orientation
information. Second, live video becomes more important when quick feedback is
needed. Third, the type of gesture cue has more influence on performance and
user preference than the type of view sharing method.
