The company says it is hoping its latest smartphones will offer an alternative for people who have to carry around their tablet computer, laptop, smartphone and camera all at once.

　　CES has been a showcase in recent years for technologies that free users from keyboards, mice and buttons.

　　Swedish company Tobii Technology is at CES to demonstrate its REX product, which, as CEO Henrik Eskilsson explains, is its "latest eye-tracking sensor."

　　"So, basically, this is an eye-tracking sensor that allows a computer to know exactly where on the screen you're looking. We integrate that concept of eye control together with the keyboard, mouse or touchpad to create a revolutionary new user interface for the computer."

　　CES runs until January 11th.
