‘‘All the PC manufacturers recognize that they have to do things differently,’’ Accenture’s Puri said.
___ ATTENTIVE COMPUTING
CES has been a showcase in recent years for technologies that free users from keyboards, mice and buttons. Instead, they rely on cameras and other sophisticated sensors to track the user and interpret gestures and eye movements. Microsoft’s motion-tracking add-on for the Xbox 360 console, the Kinect, has introduced this type of technology to the living room. Startups and big TV makers are now looking to take it further.
For example, Tobii Technology, a Swedish company, will be at the show to demonstrate ‘‘the world’s first gaze interaction computer peripheral’’ — basically a camera that tracks where the user is looking on the screen, potentially replacing the mouse.
PointGrab, an Israeli startup, will be showing off software that lets a regular laptop webcam interpret hand movements in the air in front of it.
Assaf Gad, head of marketing at PointGrab, said that CES is usually full of hopeful companies with speculative interaction technologies, ‘‘but this year, you can actually see real devices.’’
