The HoloLens is packed with a bunch of hardware. At the core of it is an unreleased Intel Atom chip. Microsoft says it contains a CPU, GPU and HPU (holographic processing unit). Let’s look at the hardware controls that are visible from the outside.
At the center of the first picture above, there is a circular gear on the inside band. The inside band is the main part of the HoloLens that rests on your head. It is also were the majority of the weight is felt, albeit a very lightweight device. Some of the Microsoft HoloLens team members have recommended putting the front end of the inner band at about the hairline to have the most comfortable wear. This gear expands and contracts the inner band to fit around a head.
The red pieces on the bottom of the HoloLens are the spatial speakers. In the close up picture, you can see it’s an elongated piece. This contains a bunch of smaller speakers to help with the spatial perception.
Here is a close up from the bottom of the HoloLens. Worth looking at is the layers of the inside lens.
On the top side, roughly over the ears, there are controls for Brightness on one side and Volume on the other side. They are plus and minus type of buttons.
I’ve gotten a lot of questions about whether someone can wear their classes. The HoloLens definitely supports glasses. In the picture above, on the inside band behind the speakers, you can see an open slot. That is for sliding the outside band in relation to the inside band. This allows for extending the outside band either closer or farther away from a face. The only glass wearer that I’ve talked to that experienced trouble was with heavy bifocals. That person had success after going through the HoloLens configuration without her glasses.
On the back of the outer band, there is a button for the power, along with a 5 light power indicator. The button is a long-press type to avoid accidental power-offs. On the bottom of the HoloLens in the same area is the micro-USB port for charging.
Finally, we look at the clicker. The clicker has a micro-USB port for charging, which is the same as the HoloLens. The strap is elastic and is best to wrap around your middle or ring finger. There is a bluetooth pairing button on the underside of the clicker that is small enough to require a pencil or pen tip sized object to start the pairing. The Clicker can work as a replacement for the common AirTap gesture, which is very nice in development scenarios.
