A closer look at the Microsoft HoloLens (pictures)

The Microsoft HoloLens headset. Or more specifically, the current $3,000 developer version of the upcoming headgear. There's no price or release date for a consumer version yet.

Inside the visor, a pair of lenses. They let you see 3D, computer generated objects that appear to exist in your real world.

Physically, the headset is a pair of concentric bands. The inner one goes on your head, while the outer one can slide along tracks to be positioned closer or further from your face.

Here's how the current HoloLens fits on the wearer's head. Note how the inner ring opens up to an angle, and is propped up on the forehead.

The power button and battery life indicators live at the rear, inside one of the flexible stems. It's not too hard to reach around and press it.

A view from underneath. You can see the two speakers (in red), the padding, and some vents for cooling the system.

On top of the headset's outer ring are some buttons for adjusting volume and brightness.

The reason the HoloLens is so good at what it does is because it uses an array of cameras to scan your surroundings in 3D. Then it knows where your walls, furniture and floor are located.

Lots of sensors embedded in the front, and a very glossy visor.

Inside the lenses, you can often see a rainbow glint.

The Development Edition comes in this carrying case, along with a few accessories. There's a clicker if you don't want to AirTap, and some optional straps to keep it better balanced on your head.

Here's the box that the Development Edition comes in.
