Japanese technology titan NEC has unveiled a gadget that allows users to control their TV, mobile phone or tablet computer using a virtual input device.
The company said a camera that recognises three-dimensional shapes and their movements will combine with a projector that could show the image of an input device - such as a keyboard - on almost any surface.
Users can then gesture at the projected image to move an electronic file or play a video, with the movement of their hand relayed back to the device they want to control.
'With the recent expansion of cloud-based services, information terminals have become increasingly diversified, ranging from PCs to smartphones and tablet devices,' a company statement said on Tuesday.

It will be useful. I often have difficulty in typing on my smartphone because of small size keyboard displayed on the screen.
But, when we use virtual keyboards in public such as in trains, it may be ashaming. What we type on the virtual keyboards are visible by people around us.
By the way, My senior researcher who works at NEC sent me an e-mail about his college days' friends.
I wonder if he knows the announcement of NEC.
