"It looks like the rivalry between Samsung and LG is about to get even more heated. \nAccording to a report by Yonhap News, LG has called out its fellow Korean competitor for possible patent infringement on a feature that pauses video playback when you look away from the screen.\nSamsung announced last week that its new Galaxy S 4 smartphone would include Smart Pause, which recognizes when you're watching video and pauses the clip if you turn your head away. \nDuring a preview of the Galaxy S 4 device before the launch, the company made it clear that it isn't using eye-tracking technology. Instead, it uses facial recognition. \nSEE ALSO: 10 Strange Pictures From the Samsung Galaxy S 4 Launch\n\nThe day before, however, LG said Smart Video \u2014 which uses eye tracking to control video playback \u2014 would be coming to its Optimus G Pro device. With Smart Video, LG says the phone recognizes the position of the eyes to automatically play or stop a video.\nLG said it applied for a patent to protect the feature back in 2009. Samsung filed for a patent for \"Eye Pause\" in February 2013.\nThis isn't the first time LG and Samsung have released similar products. Samsung has previously slammed LG with a patent lawsuit regarding its LCD displays, and at the 2013 International Consumer Electronics Show, Samsung unveiled a curved OLED TV just hours before LG touted what it called the world's first curved OLED TV.\nImage by Mashable"^^<http://www.w3.org/2001/XMLSchema#string>
