Lenovo showcased a new pico-projecting smartphone concept,Smart Cast at its TechWorld event in Beijing today. This smartphone features a built-in pico projector and laser sensors, which not only let you project your smartphone’s display onto a larger surface, but interact with it as well. Samsung came out with a similar device a few years ago and there have been virtual laser keyboards for even longer. Lenovo’s concept, called Smart Cast, combines the two into one device.
While still in development, Smart Cast can recognize several gestures, including clicking, swiping, and multitouch, so you can interact with your smartphone as you would on its display. The projector on the phone can also rotate so it can be used to display images on a wall for presentations and movies. A small kickstand on the back of the phone lets it stand up on its own, so you don’t have to prop it up against something else. The smartphone measures 34mm x 26mm x 5mm.
At Lenovo Tech World, the smartphone was demonstrated by the pianist Lang Lang, who used the technology first to project a virtual keyboard onto a table, where he played Scott Joplin’s The Entertainer. Next, used the projector to show sheet music above a piano, and swiped between pages as he played a classical piece on the piano. In both cases, the phone was very responsive, as Lang played effortlessly, with no lag at all.
