Small digital projectors are in the works. These devices, when plugged into cellphones and portable media players, will let consumers beam video content from their hand-held devices to the closest smooth surface -- entertaining themselves, annoying their neighbors and possibly contributing to a new warning sign: "No Projectors in This Area."
The microprojectors, still in prototype stages, use light-emitting diodes, lasers or a combination of the two to cast a display in darkened spaces of up to 50 or 60 inches wide, or 130 to 150 centimeters, and perhaps even wider, and of 7 to 20 inches wide when there is ambient light.
