Tiny, laser-based projectors could transform these pocket-size devices into full-blown entertainment systems by shining images onto walls, tabletops or the backs of airplane seats. In a bright room, the handheld projectors would produce images about as bright and big as a 10-inch laptop screen, said Greg Niven, the vice president of marketing at laser maker Novalux. “If you turn the lights out, you could make the projection 10 feet,” he said.
