Abstract
A vision system associated with a projection system includes multiple optical pathways. For instance, when the projection system projects an image onto a generally vertical surface, the vision system may operate in a rear sensing mode, such as for detecting one or more gestures made by a user located behind the projection system. Alternatively, when the projection system projects the image onto a generally horizontal surface the vision system may operate in a front sensing mode for detecting gestures made by a user located in front of the projection system. One or more thresholds may be established for switching between the front sensing mode and the rear sensing mode based on orientation information. As another example, the vision system may be operated in both the front sensing mode and the rear sensing mode contemporaneously.
