INTERACTIVE PROJECTION SYSTEM

摘要

An interactive projection system for outputting illuminated indicia upon a projection surface. A detection system is operable to detect both stationary and movable features. A control system is operable to determine the position of the stationary and movable features. A reflective device reflects light from a light source (natural and/or artificial) upon the projection surface as the illuminated indicia. A drive system moves the reflective device, thereby moving the illuminated indicia across the projection surface in response to control system thereby simulating the stationary feature on the projection surface as a physical boundary to the illuminated indicia and simulating the movable feature contacting the illuminated indicia.

1. An interactive projection system for outputting illuminated indicia upon a projection surface, the projection surface having a stationary feature and a movable feature, the stationary feature defining a perceived spatial limit inhibiting movement of the indicia across the projection surface, the movable feature defining a perceived engaging member contacting the indicia, the interactive projection system comprising:
a detection system directed toward at least a portion of the projection surface, the detection system outputting a detection signal in response to the stationary feature and movable feature; a control system operable to receive the detection signal and determine a position of the stationary feature and the movable feature, said control system determining a boundary of the projection surface based on the determined position of the stationary feature and the movable feature and outputting a projection control signal in response to the determined boundary, a reflective device reflecting light from a light source upon the projection surface as the illuminated indicia; and a reflective device drive system coupled to the reflective device, said reflective device drive system is configured to move the reflective device thereby moving the illuminated indicia across the projection surface in response to the projection control signal thereby simulating the stationary feature on the projection surface as a physical boundary to the illuminated indicia and simulating the movable feature contacting the illuminated indicia.
