Samsung is moving away from the gimmicks of gesture control and seems to want make it more useful for users. The Korean tech giant aims to integrate single-finger gesture support for next year’s line of smart TVs. For example, you can return to a previous screen or stop a video by motioning your finger counterclockwise. Next year’s Samsung TVs will also feature improved voice control capabilities, like just mentioning the channel number to switch channels.
