TIRED of hearing other peopleâ€™s cellphone conversations? It may become worse. Soon you may have to watch their favorite television shows and YouTube videos, too, as they project them onto nearby walls or commuter-train seatbacks.
Pint-size 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 â€” entertaining themselves, annoying their neighbors and possibly contributing to a new warning sign: No Projectors in This Area. The microprojectors, still in prototype, use light-emitting diodes, lasers or a combination of the two to cast a display of up to 50 or 60 inches, or perhaps even wider, in darkened spaces and 7 to 20 inches or so when there is ambient light.
