In a few years, Samsung’s new Internet-connected TVs might come with an extra function that you may not have expected: switching on and off living room lights. “It will be a new interface that drops the usage of cursors, allowing the user to point to objects that exist beyond the TV screen,” Kim Seok-joong, the chief executive and founder of the start-up behind the technology told The Wall Street Journal in a recent interview. Kim and his company, VTouch, are currently in talks with Samsung, bidding for a deal to supply a gesture-control software solution to the world’s top TV manufacturer. The Seoul-based startup also recently won an undisclosed amount of investment from another Samsung affiliate. A Samsung Electronics spokesman declined to comment.
