Microsoft HoloLens Development Edition

The Microsoft HoloLens consists of a big black headband and a transparent black visor.

The visor contains the bulk of the electronics. It's a large, smoke-colored plastic shield on the front of the headband that extends over the front, protecting the various sensors and the display.

Multiple sensors, including four environment cameras, one depth camera, and an ambient light sensor, cover a wide arc in front of the user.

The headband wraps completely around the head above the ears, with thick, fixed arms that connect to the visor and an adjustable, padded back strap with a wheel that extends or contracts to fit the size of your head.

The arms feature their own speakers, small orange rectangular protrusions that project sound toward the wearer's ears.

The Clicker is a small one-button remote that simply lets you click on whatever you're looking at, using a small dot in the center of your view as a cursor.

A wheel on the back of the headband lets you tighten it to fit your head.

The left arm features a power button and five-LED battery indicator on the back, a micro USB port for charging with the included cable and power adapter on the underside, and two buttons that adjust display brightness on top.

The right arm has a 3.5mm headphone jack on the bottom and volume control buttons on top.

Small buttons on either arm control display brightness and speaker volume.
