It is no secret that smartwatches are pretty cool. At the same time, it is also no secret that they're a pain to use at times. For many users, especially those who were gifted with sausage fingers, using smartwatches could be a tricky affair, mainly because the screen on the device is just too darn small. Well, Samsung might have just filed a patent to solve that problem.

A recent patent granted to the South Korean tech giant includes a pretty nifty feature. In a sense, Samsung's patent turns skin, or any other surface, into an extension of the smartwatch's screen through the use of a special projector.

Thus, users attempting to call their contacts through their watches do not need to struggle with the small screen of their devices anymore. With Samsung's new technology, the keypad for dialing would be projected onto the back of the users' hand, allowing for pretty easy use.

The magic of the technology lies in the mini projector embedded inside the device. The projector essentially beams UI elements such as dial pads, notifications, or menu options to users' skin. Once the user touches his or her skin, a built-in camera inside the smartwatch would process the input, allowing a dedicated chipset to translate the actions into mobile or virtual actions.

But that is not all. From what the patent has revealed so far, it seems like Samsung is not limiting the applications of the technology to human skin alone, as there are some illustrations in the patent that features the smartwatch projecting onto other surfaces such as doors and walls. Doing so, of course, enlarges the virtual interface even more, allowing for more control and actions.

Of course, only time will tell if Samsung does go forward with the design featured in the smartwatch patent. After all, tech companies such a the Korean giant are known to file multiple patents, with a number of them never making it to consumer products.

Considering the possible applications of the wearable projector, however, one could only hope that at some point, Samsung would include the nifty feature in its future devices.
