1. A system for two-dimensional (2-D) or three-dimensional (3-D) display of images, comprising: a projector for projection of the 2-D and 3-D images; multiple pairs of glasses for viewing the 3-D images; a first transmitter in the projector for synchronizing the projector with the glasses for viewing 3-D images; a switch in each pair of glasses to detect whether the glasses are powered on or powered off; a second transmitter in each pair of glasses for transmitting power on/power off information; a receiver in the projector for receiving power on/power off information from the second transmitters and sending power on/power off information to a processor; and a processor for analyzing the power on/power off information received from the second transmitters and determining whether to project 2-D or 3-D images responsive to the analyzed power on/power off information.
