Samsung's MediaSquare can either transform a boring party into a fun one or make you want to punch the asshole in the room. The user interface allows everyone to control and interact through a TV, you see, replacing remote controls with everyone's phones. For instance, you and your friends can flick videos, music tracks and photos to the TV all at once, which appear as floating elements on screen. Anybody can switch the music being played or even adjust the volume either through a phone or through a smartwatch. If that sounds hard to envision, the video below the fold can show you exactly how it works.
