Although Google Glass (aka Project Aura), as cool as it is, isn't very immersive, Google has filed for a patent on a "head wearable display" that would show holograms, Engadget reports.

The hope is that this would create an augmented reality experience that's more involving than what you get today, including a wider field of view a more efficient, easier-to-wear headset.

There's no certainty that Google will do something with the technology, assuming the patent is granted. Microsoft's HoloLens may not get fresh competition any time soon. However, it's no secret that Google is not only working on the next version of Glass, but has poured lots of cash into augmented reality efforts like Magic Leap's still-mysterious project.
