Smartwatch makers have tried a few ways to overcome the limitations of a tiny wrist-worn screen, such as gestures, pressure sensitivity or voice commands. Samsung thinks there might be a better way, though: moving the display beyond the watch. It's applying for a patent on a concept that would project a wearable's interface on to everything from your hand to the wall. It'd use sensors to detect those outside-of-the-wrist interactions, and it could even detect the geometry of your hand to adapt the interface to that area. You might see extra buttons on your fingers if your palm is open.
