Making use of a full scale keyboard (gaming screen or piano) the concept device projects onto a surface below, which enables users to make use of what is effectively virtual hardware.
The focus free projector is significantly different to those already available on pocket devices and as well as being able to cast a keyboard it will also be able to cast films and games onto a wall like a standard projector.
Details on when the technology powering this concept will make it to the consumer market are scant and those present at the conference reported that no pricing or availability details were made available.
Demos included Fruit Ninja projected onto a desktop surface, a musical keyboard, integrated kickstand and an illustration of how the projector flip around to project images in a desired direction.
Although various devices have attempted this sort of technology before, none have been winners in the commercial market but hopefully Lenovo can find to turn this concept into a commercial success.
