Sony reveal its Xperia Projector Prototype at CES2017

it's basically projector that can project a screen onto a surface and uses IR sensors to turn the surface into a 10-point multi-touch screen.

In CES 2017 Sony reveal its Xperia Projector prototype which projects a screen onto a surface in front of the projector and uses IR sensors to turn the surface into a 10-point multi-touch screen; it can also project up to an 80-inch image onto a nearby wall. It runs full, regular, Google Play-compatible Android, working with whatever apps you want, from Google Now to Minecraft PE. It connects to local Wi-Fi networks and plugs into the wall for power.

The projector was easy and responsive to use. Web browsing and games sped along, and the virtual touch screen worked very well. In the entertainment context, it really needed a remote, though. Sony noted that you can attach Bluetooth devices or use a PS4 controller to work it remotely, but I think it should come with a remote (or a smartphone app that functions as a remote) if it's ever sold.
