Abstract
Transparent displays can be used to support collaboration,
where collaborators work on either side while
simultaneously seeing what the other person is doing. This
naturally supports workspace awareness: the up-to-the-moment
understanding of another person’s interaction with
a shared workspace. The problem is that the transparency of
such displays can change dynamically during a collaborative
session, where it can degrade as a function of the density and
brightness of the displayed graphics and changes in lighting.
This compromises workspace awareness. Our solution is to
track and graphically enhance a person’s touch and gestural
actions to make the feedthrough of those actions more visible
on the other side. We had subjects perform three tasks over
degrading transparency conditions, where augmentation
techniques that enhance actions were either present or
absent. Our analysis confirms that people’s awareness is
reduced as display transparency is compromised, and verifies
that augmentation techniques can mitigate this awareness
loss.
