Lenovo showcased a concept smartphone that comes with a built-in projector which can make any surface touch responsive. Lenovo intends to deliver the experience of a touch screen on any surface with its smartcast technology.
The company said that "With a combination of the world’s first laser projector and high-accuracy IR sensors, the smartcast concept phone can project a keyboard on a table, let you play a game or even be used as dual screens.”
High-accuracy IR sensors are used in the smartcast technology. With this technology, you can type anything on the phone without using the device's screen. With smartcast you can play games on a table or a wall.
Lenovo hasn’t revealed much about the smartcast technology. The smartcast technology is still being tested by the company to improve the overall experience.
