New TVs from Samsung will recognise an expanded range of gestures so people can swipe through on-screen menus in a way that revolutionises the old remote control.
Samsung, the Korean electronics maker that is successfully challenging Apple in smartphones, touts the new user interface as faster and more intuitive than before.
Samsung said the new interface will be a feature of upcoming smart TVs. In addition, certain high-end Samsung smart TVs sold since last year can be upgraded with an add-on kit — complete with the required quad-core processor — that will be sold separately for a few hundred dollars.
Samsung President Boo-Keun Yoon said the new features are designed to make TV viewing easy as consumers face more and more choices in what they watch.
"We have developed TVs that respond to people's needs and lifestyles, TVs that know in advance what people want to watch, TVs that have the power to create the ultimate lean-back experience," Yoon said.
At the Consumer Electronics Show in Las Vegas, Samsung also introduced an 85-inch "ultrahigh-definition" set, in line with rivals that are all rolling out screens with four times the pixels as the current HD. The higher resolution will let TV screens get larger and people to sit closer without a decline in picture quality, though initially the price tag will limit those sets to technology's early adopters.
The new lineup of smart TVs respond to more natural speech and motion, similar to the way the Kinect controller on an Xbox 360 game console allows users to swipe through menus by gesturing in the air. The camera is mounted on top of the screen and can be folded back for people concerned about privacy.
Earlier on Monday, LG unveiled a new Magic Remote, which acts like a wand that is sensitive to motion and is used to navigate on-screen menus. LG said the new model responds better to natural speech and can be controlled with a single finger. It also lets you change the channels by writing numbers in the air.
Samsung's new handheld remote control comes with a touch-sensitive clickable track pad, which is another way to navigate through viewing options.
Because it is integrated with Facebook, Twitter and YouTube, the new interface accepts text input. There are a range of options for typing — through a synced smartphone, a Bluetooth-enabled wireless keyboard accessory, using hand gestures for an on-screen keyboard, or using its voice-to-type software.
Search functions also span web video apps and live TV, meaning that searches of a show will inform viewers if and when an episode is available on live TV, or if it's available through an app such as Netflix.
Nintendo's Wii U game console does something similar by showing search results from live TV and web video apps. But by being integrated with the TV, Samsung's universal search function doesn't require the user to change the TV's source input.
And since you can also play some games on its new smart TVs, the new sets from Samsung are acting more and more like mobile computing devices with an extra-large screen.
