Sources have told Re/code that HP will show a new computing device on 29th October, which is called Sprout.
According to the sources, the Sprout combines a large flatscreen display with a flat, touch-sensitive work surface. There is also an overheard device holding a projector and 3D scanner. Images are projected down onto the worktop and can be manipulated with hands or pens. New elements can be added to the image using the 3D scanner.
Initially, Sprout will run Windows; however, future versions could use the ChromeOS. It will apparently be just one of the devices on show at the event.
