At the Consumer Electronics Show in Las Vegas opening today, LG and Lenovo will show TVs that allow users to search for shows and Web applications with natural-sounding voice commands. Samsung introduced three high-end models with so- called Smart Interaction technology, which builds in motion- sensing and voice-command software similar to Microsoft Corp.'s Kinect peripheral for the Xbox 360 video-game console.
"You now can turn on your TV simply by saying, 'Hi TV,' and you can change channels simply by talking or gesturing," Ethan Rasiel, a spokesman for Suwon, South Korea-based Samsung, said in an interview.
Getting consumers to pay up will be tough. Last year, most buyers shunned sets bringing "Avatar"-like 3-D theater experiences into the living room. Since 2009, the average price of an LED TV, the most common type sold in the U.S., dropped 35 percent to $817 from $1,254, according to researcher NPD, which projects a 16 percent decline this year. Three-dimensional sets made up 9 percent of sales in 2011 through November, from 2 percent a year earlier.
