A new patent from Samsung, published by the United States Patent and Trademark Office (USPTO), shows a concept smartwatch interface designed to project a touch-enabled display onto the back of the user's hand.
The concept device looks awfully ambitious. Basically, it scans the back of the user's hand in order to detect the display area. Then, the device projects different interactive panels onto the hand. This extra display could be used to provide larger keyboards and keypads.
The touch-enabled area could also serve as a larger plot when using handwriting recognition for input, and certain applications show extra virtual buttons being displayed on the rear of the user's fingers.
The patent takes things a step further, showing the concept smartwatch throwing projected panels onto other surfaces, such as a keypad on a security door.
There’s no way of verifying whether anything will be done with this just yet, but the concept is interesting. And, although it might just be a concept for now, it does show that Samsung is looking past how consumers currently interact with wrist-based wearables.
