Headset with virtual reality and augmented reality features.
Microsoft is currently developing HoloLens, a wearable computer that layers digital elements over the real world. Google has invested in Magic Leap, a startup that has similar aims, creating "mixed reality" images with a dedicated headset. It is not clear if the headset Google is currently developing will complement Magic Leap's technology or if it's an entirely separate project.
While it does have a screen, it will offer features more in line with augmented reality systems than existing VR headsets, which are presently focused on gaming. There is no release date in sight for the headset, but it remains an important part of Google's future plans.
