"You've got Panasonic showing forward facing video in the home entertainment environment. Instead of using a conventional remote control you hold up your hand and it recognises you have done that," he said.
"It also recognises your face and that you are you and it will display on your TV screen your menu. You can move your hand to move around and select what you want," he added.
"Sony and Canon and other video and photographic manufacturers are using face recognition that recognises your face in real time," he said. "And it recognises even when you smile."
"You even have emotive systems where you can wear a headset and control a computer by simply thinking and that's a device set to hit the market in September."
"This" Mr Prentice said, "is all about using computer power to do things smarter."
