Abstract

A method and system for projecting an image. An image projection system may include a sensor configured to detect the presence of an observer within a proximity of a medium, e.g., screen, window. In response to the sensor detecting the presence of an observer within a proximity of the medium, one or more portions of the medium may be switched from a transparent state to a substantially translucent state. At a substantially concurrent time as switching the one or more portions of the medium to a substantially translucent state, an image may be projected onto such portion(s). Hence, an image may be displayed in response to detecting an observer within the proximity of the medium.
