Abstract:
1. A system comprising: a memory; a processor; a projector to project content onto a surface in an environment; an infrared (IR) emitter to emit IR light onto the surface in the environment; a depth sensor to receive at least a portion of the IR light reflected from the surface and to produce depth data at discrete times for use in determining a distance to the surface; an analysis module stored in the memory and executed on the processor to receive the depth data produced the depth sensor and to average the depth data produced over multiple discrete times to produce averaged depth data, wherein the averaged depth data is used at least in part to focus the projector for projection of the content onto the surface; a first application stored in the memory and executed by the processor to provide first content for projection by the projector, wherein the analysis module is configured to average the depth data over a first number of the multiple discrete times when the first application is being executed to provide content for projection; and a second application stored in the memory and executed by the processor to provide second content for projection by the projector, the second content being different from the first content, wherein the analysis module is configured to average the depth data over a second, different number of the multiple discrete times when the second application is being executed to provide content for projection.
