Supporting Awareness in Mixed Presence Groupware (02 Feb 2005)
Mixed presence groupware (MPG) is software that
connects both collocated and distributed collaborators
together in a shared visual workspace. Our early study of
this new genre is that people focus their collaborative
energy on collocated partners at the expense of remote
partners, which imbalances collaboration. We call this
problem presence disparity, caused by the imbalance of
awareness exuded by virtual embodiments versus actual
people. VideoArms is an embodiment technique that
mitigates presence disparity by enhancing awareness of
remote collaborators in a mixed presence workspace. We
describe how VideoArms works, and the design principles
behind its construction.
