MultiView adds a new level of spatial fidelity to the
many-to-many video conferencing experience by providing multiple views but giving
each person in the conference the single unique and correct view of the remote
side. This new level of spatial fidelity restores many of the
non-verbal and spatial cues lost in typical single-view video conference
systems -- like eye contact and deixis -- and improves the overall
effectiveness of remote collaboration.
Three remote participants are gazing toward their right
(viewer's left). Column 1 is the view from the left position, column 2, the
center position, and column 3, the right position. The top row is what is seen
from the respective positions with standard (non-directional) video
conferencing. Notice that from all viewing positions, all remote participants
appear to be gazing toward the left -- even the participant they are looking
toward will perceive this -- demonstrating perspective invariance. The bottom
row is what is seen using MultiView and shows appropriately changing
