Abstract:
In this research, we explore using pointing and drawing in a remote
collaboration system. Our application allows a local user with a tablet to
communicate with a remote expert on a desktop computer. We compared
performance in four conditions: (1) Pointers on Still Image, (2) Pointers on
Live Video, (3) Annotation on Still Image, and (4) Annotation on Live Video.
We found that using drawing annotations would require fewer inputs on an
expert side, and would require less cognitive load on the local worker side.
In a follow-on study we compared the conditions (2) and (4) using a more
complicated task. We found that pointing input requires good verbal
communication to be effective and that drawing annotations need to be erased
after completing each step of a task.
