The way we interact with computers has been transformed in recent years, as we move from the mouse and keyboard to the touchscreen experience. CES, once the place to see the latest personal computers, will still have plenty on show. But many PC laptops will be convertibles, designed to turn into tablets for the hybrid environment of Windows 8.
We will also see more voice-activated devices, though the jury is out on how keen we are to talk to our PCs and phones. There may be more excitement around the idea of gesture controlled devices, using technology like that in Microsoft's XBox Kinect system.
