Abstract (en)
[origin: WO2009061620A1] A dual-mode projection apparatus has a projection module for projecting an image onto a projection surface. An image sensor module captures images of the projection surface and determines spatial and temporal characteristics of a visible light spot superimposed on the projection surface. A communications module transmits the spatial and temporal characteristics of the visible light spot to a remote device for remote control of the device based on the spatial and temporal characteristics of the visible light spot.
