First Claim
1. A system comprising:
- a projector to project light corresponding to an image in a projection direction toward a display surface;
one or more processors;
one or more computer-readable media;
at least one light emitter configured to emit non-visible light;
a light sensor to detect the non-visible light; and
one or more modules maintained on the one or more computer-readable media which, when executed by the one or more processors, cause the one or more processors to perform operations comprising;
ascertaining whether the projector is (1) oriented so that the projection direction is within a first range of directions that includes a substantially horizontal direction or (2) oriented so that the projection direction is within a second range of directions that includes a substantially vertical direction;
based at least partly on a first determination that the projector is oriented so that the projection direction is within the first range of directions, emitting first non-visible light in a first direction away from the projection direction, receiving at least a first portion of the first non-visible light reflected from one or more first objects in an environment, and detecting at least one first gesture in a first area outside of the first range of directions relative to the projector based on first information generated from the first non-visible light reflected from the one or more first objects in the environment;
based at least partly on a second determination that the projector is oriented so that the projection direction is within the second range of directions, emitting second non-visible light in a second direction toward the projection direction, receiving at least a second portion of the second non-visible light reflected from one or more second objects in the environment, and detecting at least one second gesture in a second area within the second range of directions relative to the projector based on second information generated from the second non-visible light reflected from the one or more second objects in the environment.

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.
