Over in Las Vegas, Samsung took the stage today to make some big announcements in the field of home theatre and entertainment, with some new ideas added to Samsung’s lineup.

No less than four new technologies were announced today for Samsung’s new line-up of television sets, with Samsung announcing that more than half of the models released in 2012 would support 3D.

But viewing in the third-dimension is hardly new, so Samsung announced that this year, the company would be releasing a new way of controlling your TV.

The built-in camera and microphone in the new Samsung ES8000 LED TV.

Called “Smart Interaction”, TVs would use voice control, hand gestures, and face recognition to take charge of the TV set. According to Samsung, you’ll be able to turn the TV on and off by speaking, load up applications, search the web, and more, thanks to a built-in camera and dual-microphones.

With this new way of controlling your TV, Samsung intends to have even more applications available, with the addition of infotainment choices for kids, fitness apps that take advantage of the built-in camera, and an app called “Family Story” that essentially turns the TV into a giant family sharing notice board.

The technology inside the TV is changing too, with a faster processor being thrown in some of the new TVs. You might not think that a TV needs a lot of speed, but Samsung has today said that the dual-core processor thrown into televisions will make multitasking better, provide a “smoother web browsing experience”, and even result in better image quality.
