A further example shows a map screen on the smartwatch and supporting details (like a description or address) projected onto the wrist, effectively giving the watch dual-screen capabilities. We also see buttons projected onto knuckles and fingers, as well as menu options listed alongside the wrist when the arm is held pointed vertically.
And that’s just the nearby projection: another illustration shows a large image projected from the watch onto a nearby door or wall, with the same kind of touch interactions allowed. The patent also showcases a wearable headset with projection tech, which could provide an experience somewhat akin to Microsoft’s HoloLens.
It appears that the watch concept would use a small camera to detect the surface of your hand and arm, allowing the interface to perfectly fit within your individual shape, and sensors would detect your interactions. This sort of projection technology would seemingly open up augmented reality opportunities as well, whether used for advanced interfaces or entertainment purposes.
It all looks decidedly futuristic, like something we’d see in a sci-fi movie or spy thriller – but for now, it’s just illustrations on a patent application. We have yet to see any indication that Samsung is anywhere near producing this kind of device, but we can’t help but hope this kind of inventive tech is coming sooner rather than later.
