The Microsoft HoloLens will be an impressive, yet expensive headset once it is finally released to the public. This week at Microsoft's Build conference, the future device was the highlight of the show, CNet reported.

The HoloLens will display 3D images in front of a user's eyes. The 3D images will intermingle with a user's real-world environment to create a unique experience.

Microsoft's upcoming headset is not trying to be a virtual reality device. Instead, it is an "augmented reality." Someone wearing the device could see some objects on a table that are not really there, and they will be able to interact with them as if they were real and actually in front of them.

When someone who is not wearing a HoloLens sees someone who is wearing one, they will think some of their movements are strange. The HoloLens user will walk around things that are not really there, make tap or "click" gestures in the air (Microsoft calls this air-tapping) or even make some vocal reactions like "ooh" or "ahh."

Like Apple's Siri or Windows Phone's Cortana, the HoloLens will respond to vocal commands that a user gives it.

The HoloLens skips out on the use of headphones and instead puts small "floating audio" speakers near the user's ears. These speakers will be loud enough to hear things but not too loud to make outside noises inaudible.

The headset has a total of seven cameras built into it. Two cameras are on each side of the visor and then there are three in between these two pairs, Gizmodo reports.

The HoloLens will be optimized for Windows 10. Users of the HoloLens will be able to interact with their computers in a whole new way.

The price of the HoloLens is expected to be expensive, at least during its initial release. An unnamed Microsoft executive told The New York Times that the headsets would cost significantly more than a console like an Xbox One.

What do you think of the Hololens? Is this going to be the future of wearable tech?
