HoloLens blends the holographic with the "real" world, placing holograms in your surroundings. A holographic app window "hangs" on the wall, a holographic ballerina spins on the tabletop, bunny ears sit on top of your unwitting friend’s head. When you’re using an immersive game or app, the holographic world will spread to fill your surroundings—but you’ll still be able to see and move around the space.
The holograms you place will stay where you’ve put them, even if you turn off your device. Here are some things to keep in mind for the best experience with the holographic world. Note, HoloLens is designed to be used indoors in a safe space with no tripping hazards. Don’t use it while driving or performing other activities that require your full attention.
Get the best view
Holograms can be placed throughout your environment—high, low, and all around you—but you’ll see them through a view frame that extends for a few feet on either side of you. To get the best view, make sure to adjust your device so you can see the entire frame. And don’t hesitate to walk around your environment and explore!
HoloLens learns about your space so it can remember where you’ve placed holograms. HoloLens can remember multiple spaces, and is designed to load the correct space when you turn it on.
HoloLens can map and remember your spaces best if you choose the right environment.
When you enter a new space (or load an existing one), you’ll see a mesh graphic spreading over the space. This means your device is mapping your surroundings. If you’re having trouble placing holograms, try walking around the space so HoloLens can map it more fully. If your HoloLens can’t map your space or is out of calibration, you may enter Limited mode. In Limited mode, you won’t be able to place holograms in your surroundings.
HoloLens remembers the spaces you’ve used it in by associating them with what Wi-Fi networks are available in that location. A space will get its name from the Wi-Fi network that HoloLens is connected to in that location, but being connected to a Wi-Fi network or not, does not affect they way HoloLens remembers the space you are in.
When you are in a new location and HoloLens does not recognize the Wi-Fi networks around you, it will create a new space, which will have a default name since you are not connected yet, so once you connect to the Wi-Fi network, the space name will change to be the same as the Wi-Fi network. Note that this is not the case where you first set up your HoloLens and connect to Wi-Fi, by the time you are done with the initial set up, a space will already be created with the name of the Wi-Fi network you connected to.
When you go to a location that HoloLens recognizes, the space for that location will be automatically loaded and any holograms that were already placed in that space will appear as well.
You can see and manage your spaces by going to Settings > System > Spaces. There, you can remove a space you no longer need or load the space you want. There are important points to have in mind when using HoloLens and managing spaces:
For your holograms to look crisp, clear, and stable, your HoloLens needs to be calibrated just for you. When you first set up your HoloLens, you’ll be guided through this process. Later on, if holograms don’t look right or you’re seeing a lot of errors, you can make adjustments.
If your holograms look jittery or shaky, or if you’re having trouble placing holograms, the first thing to try is the Calibration app. This app can also help if you’re experiencing any discomfort while using your HoloLens.
To get to the Calibration app, go to Settings > System > Utilities. Select Open Calibration and follow the instructions.
If you run the Calibration app and are still having problems with hologram quality, or you’re seeing a frequent “tracking lost” message, try the Sensor Tuning app. Go to Settings > System > Utilities, select Open Sensor Tuning, and follow the instructions.
If someone else is going to be using your HoloLens, they should run the Calibration app first so the device is set up properly for them.
