The folks at Magic Leap remain tight-lipped about what the device looks like and exactly how it functions, but a recently uncovered patent application may provide some helpful clues.

Filled with a wide range of illustrations detailed all manner of head-mounted displays, the drawings don't confirm what the Magic Leap hardware will look like, but it at least offers some hint at what the company is thinking.

In fact, there are so many drawings of would-be gadgets (rings, gloves, cubes, keyboards etc.) and mechanisms in the patent (filed in January and surfaced by Business Insider) that it almost seems like a deliberate attempt to obscure the true nature of the system. Or, it could be a hint at the vast possibilities inherent in the system. At this point, we just don't know. Therefore, we're mostly focusing on the head-mounted device.

We see everything from shoppers using the glasses to watch a virtual screen, play an augmented reality game (hidden in vegetables at the supermarket!), help perform surgery and even share experiences during a yoga session.

As with all patent drawings, what you see isn't necessarily what you'll get later as a commercial product, but in the meantime, these images can tide you over while Magic Leap maintains its hype-fueled campaign of secrecy.
