Microsoft HoloLens 2 is a pair of mixed reality smart glasses developed and manufactured by Microsoft. It offers one of the most comfortable and immersive mixed reality experience available.
Place the HoloLens 2 on your head. If you wear eyeglasses, leave them on. The brow pad should sit comfortably on your forehead and the back band should sit in the middle-back of your head.
If necessary, extend the headband by turning the adjustment wheel, and then loosen the overhead strap.
The overhead strap isn't required, but it can make wearing HoloLens 2 more comfortable during long periods of use.
To detach the front of the overhead strap, unhook the strap and slide it through the retractable loop on the brow pad. To reattach it, pull out the loop and slide the strap back through.
To detach the back of the overhead strap, press the button below each connection tab and pull gently. To reattach it, push the connection tabs back into the slots until they click.
You can rotate the visor up while wearing the HoloLens, which makes it easier to view and interact with real life objects, without taking the HoloLens off.
HoloLens has sensors that can see a few feet to either side of you. When you use your hands, you'll need to keep them inside that frame, or HoloLens won't see them. However, the frame moves with you as you move around.
Touching the Holograms in the HoloLens is done as if the Hologram is in front of you and touch it as if you would any other real life object.
When there are no holograms near your hands, the touch cursor will hide automatically and hand rays will appear from the palm of your hands. Hand rays allow you to interact with holograms from a distance.
To select something using hand ray, follow these steps. Use a hand ray from your palm to target the item. You don't need to raise your entire arm, you can keep your elbow low and comfortable. Point your index finger straight up toward the ceiling. To perform the air tap gesture, pinch your thumb and index finger together and then quickly release them.
To grab a hologram or scroll app window content using hand ray, start with an air tap, but keep your fingers together instead of releasing them. To scroll app window content, air tap and hold on the content and then move your hand ray up and down or side to side. To grab an app window or hologram, target the app title bar or hologram with your hand ray and then air tap and hold. To open context menus, air tap and hold with your hand ray.
The Start gesture opens the Start menu. To perform the Start gesture, hold out your hand with your palm facing you. You’ll see a Start icon appear over your inner wrist. Tap this icon using your other hand. The Start menu will open where you’re looking.
Grab and use the resize handles that appear on the corners of 3D holograms and app windows to resize them. For 3D holograms, grab and use the rotate handles that appear on the vertical edges of the bounding box.
HoloLens Tips App is an app downloaded in the HoloLens that lets you explore all the controls in a fairly simple way. It is a quick way to start getting comfortable with the controls before moving on to something else. The App can be found in the All apps tab on the start menu. Once the app has started, clear instructions will be given and follow the instructions until they are completed.
Apps can be found by opening the Microsoft Store from the Start menu. To download apps, you'll need to be signed in with a Microsoft account. Some apps are free and can be downloaded right away. Apps that require a purchase require you to be signed in to the Store with your Microsoft account and have a valid payment method. The downloaded apps can be found in the Apps tab from the Start menu.
Basic development for the HoloLens can be done through the Mixed Reality Toolkit (MRTK). MRTK is an open-source, cross-platform development kit for mixed reality applications. It provides a cross-platform input system, foundational components, and common building blocks for spatial interactions.
