Steve Caplin looks at some of the weirdest ideas at the CES, including Segway's 24 mph armchair, augmented reality windscreens, a robotic chef that can't open the fridge and a loo-roll-fetching bear. He also covers a lung kit for snorkelers powered by the swimmer's legs; the Fingerbot for pressing buttons on dumb devices; the headphones that turn into loudspeakers; and how to get a VR theatre experience without leaving home.
