# Environment considerations for HoloLens
|
||||
|
||||
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.
|
||||
|
||||
## Setting up an environment
|
||||
|
||||
HoloLens devices know how to place stable and accurate holograms by *tracking* users in a space. Without proper tracking, the device does not understand the environment or the user within it so holograms can appear in the wrong places, not appear in the same spot every time, or not appear at all. The data used to track users is represented in the *spatial map*.
|
||||
|
||||
Tracking performance is heavily influenced by the environment the user is in, and tuning an environment to induce stable and consistent tracking is an art rather than a science. Many different environmental factors are fused together to enable tracking, but as a Mixed Reality developer, there are several factors you can keep in mind to tune a space for better tracking.
|
||||
|
||||
### Lighting
|
||||
|
||||
Windows Mixed Reality uses visual light to track the user's location. When an environment is too bright, the cameras can get saturated, and nothing is seen. If the environment is too dark, the cameras cannot pick up enough information, and nothing is seen. Lighting should be even and sufficiently bright that a human can see without effort, but not so bright that the light is painful to look at.
|
||||
|
||||
Areas where there are points of bright light in an overall dim area are also problematic, as the camera has to adjust when moving in and out of bright spaces. This can cause the device to "get lost" and think that the change in light equates to a change in location. Stable light levels in an area will lead to better tracking.
|
||||
|
||||
Any outdoor lighting can also cause instability in the tracker, as the sun may vary considerably over time. For example, tracking in the same space in the summer vs. winter can produce drastically different results, as the secondhand light outside may be higher at different times of year.
|
||||
|
||||
If you have a luxmeter, a steady 500-1000 lux is a good place to start.
|
||||
|
||||
#### Types of lighting
|
||||
|
||||
Different types of light in a space can also influence tracking. Light bulbs pulse with the AC electricity running through it - if the AC frequency is 50Hz, then the light pulses at 50Hz. For a human, this pulsing is not noticed. However, HoloLens' 30fps camera sees these changes - some frames will be well-lit, some will be poorly lit, and some will be over-exposed as the camera tries to compensate for light pulses.
|
||||
|
||||
In the USA, electricity frequency standard is 60Hz, so light bulb pulses are harmonized with HoloLens' framerate - 60Hz pulses align with HoloLens' 30 FPS framerate. However, many countries have an AC frequency standard of 50Hz, which means some HoloLens frames will be taken during pulses, and others will not. In particular, fluorescent lighting in Europe has been known to cause issues.
|
||||
|
||||
There are a few things you can try to resolve flickering issues. Temperature, bulb age, and warm-up cycles are common causes of fluorescent flickering and replacing bulbs may help. Tightening bulbs and making sure current draws are constant can also help.
|
||||
|
||||
### Items in a space
|
||||
|
||||
HoloLens uses unique environmental landmarks, also known as *features*, to locate itself in a space.
|
||||
|
||||
A device can almost never track in a feature-poor area, as the device has no way of knowing where in space it is. Adding features to the walls of a space is usually a good way to improve tracking. Posters, symbols taped to a wall, plants, unique objects, or other similar items all help. A messy desk is a good example of an environment that leads to good tracking - there are a lot of different features in a single area.
|
||||
|
||||
Additionally, use unique features in the same space. The same poster repeated multiple times over a wall, for example, will cause device confusion as the HoloLens won't know which of the repetitive posters it is looking at. One common way of adding unique features is to use lines of masking tape to create unique, non-repetitive patterns along the walls and floor of a space.
|
||||
|
||||
A good question to ask yourself is: if you saw just a small amount of the scene, could you uniquely locate yourself in the space? If not, it's likely the device will have problems tracking as well.
|
||||
|
||||
#### Wormholes
|
||||
|
||||
If you have two areas or regions that look the same, the tracker may think they are the same. This results in the device tricking itself into thinking it is somewhere else. We call these types of repetitive areas *wormholes*.
|
||||
|
||||
To prevent wormholes, try to prevent identical areas in the same space. Identical areas can sometimes include factory stations, windows on a building, server racks, or work stations. Labelling areas or adding unique features to each similar-looking areas can help mitigate wormholes.
|
||||
|
||||
### Movement in a space
|
||||
|
||||
If your environment is constantly shifting and changing, the device has no stable features to locate against.
|
||||
|
||||
The more moving objects that are in a space, including people, the easier it is to lose tracking. Moving conveyor belts, items in different states of construction, and lots of people in a space have all been known to cause tracking issues.
|
||||
|
||||
The HoloLens can quickly adapt to these changes, but only when that area is clearly visible to the device. Areas that are not seen as frequently may lag behind reality, which can cause errors in the spatial map. For example, a user scans a friend and then turns around while the friend leaves the room. A 'ghost' representation of the friend will persist in the spatial mapping data until the user re-scans the now empty space.
|
||||
|
||||
### Proximity of the user to items in the space
|
||||
|
||||
Similarly to how humans cannot focus well on objects close to the eyes, HoloLens struggles when objects are close to it's cameras. If an object is too close to be seen with both cameras, or if an object is blocking one camera, the device will have far more issues with tracking against the object.
|
||||
|
||||
The cameras can see no closer than 15cm from an object.
|
||||
|
||||
### Surfaces in a space
|
||||
|
||||
Strongly reflective surfaces will likely look different depending on the angle, which affects tracking. Think of a brand new car—when you move around it, light reflects and you see different objects in the surface as you move. To the tracker, the different objects reflected in the surface represent a changing environment, and the device loses tracking.
|
||||
|
||||
Less shiny objects are easier to track against.
|
||||
|
||||
### Wi-Fi fingerprint considerations
|
||||
|
||||
As long as Wi-Fi is enabled, map data will be correlated with a Wi-Fi fingerprint, even when not connected to an actual WiFi network/router. Without Wi-Fi info, the space and holograms may be slightly slower to recognize. If the Wi-Fi signals change significantly, the device may think it is in a different space altogether.
|
||||
|
||||
Network identification (such as SSID or MAC address) is not sent to Microsoft, and all Wi-Fi references are kept local on the HoloLens.
|
||||
|
||||
## Mapping new spaces
|
||||
|
||||
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. While a HoloLens will learn a space over time, there are tips and tricks to map spaces.
|
||||
|
||||
## Environment management
|
||||
|
||||
There are two settings which enable users to “clean up” holograms and cause HoloLens to “forget" a space. They exist in **Holograms and environments** in the settings app, with the second setting also appearing under **Privacy** in the settings app.
|
||||
|
||||
1. **Delete nearby holograms**. When you select this setting, HoloLens will erase all anchored holograms and all stored map data for the “current space” where the device is located. A new map section would be created and stored in the database for that location once holograms are again placed in that same space.
|
||||
|
||||
1. **Delete all holograms**.By selecting this setting, HoloLens will erase ALL map data and anchored holograms in the entire databases of spaces. No holograms will be rediscovered and any holograms need to be newly placed to again store map sections in the database.
|
||||
|
||||
## Hologram quality
|
||||
|
||||
Holograms can be placed throughout your environment—high, low, and all around you—but you’ll see them through a [holographic frame](https://docs.microsoft.com/windows/mixed-reality/holographic-frame) that sits in front of your eyes. 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!
|
||||
|
||||
For your [holograms](https://docs.microsoft.com/windows/mixed-reality/hologram) 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 you are having trouble mapping spaces, try deleting nearby holograms and remapping the space.
|
||||
|
||||
### Calibration
|
||||
|
||||
If your holograms look jittery or shaky, or if you’re having trouble placing holograms, the first thing to try is the [Calibration app](hololens-calibration.md). 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 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.

# Restore HoloLens 2 using Advanced Recovery Companion
|
||||
# Restart, reset, or recover HoloLens
|
||||
|
||||
>[!TIP]
|
||||
>If you're having issues with HoloLens (the first device released), see [Restart, reset, or recover HoloLens](https://support.microsoft.com/help/13452/hololens-restart-reset-or-recover-hololens). Advanced Recovery Companion is only supported for HoloLens 2.
|
||||
If you’re experiencing problems with your HoloLens you may want to try a restart, reset, or even re-flash with device recovery.
|
||||
|
||||
Here are some things to try if your HoloLens isn’t running well. This article will guide you through the recommended recovery steps in succession.
|
||||
|
||||
This article focuses on the HoloLens device and software, if your holograms don't look right, [this article](hololens-environment-considerations.md) talks about environmental factors that improve hologram quality.
|
||||
|
||||
## Restart your HoloLens
|
||||
|
||||
First, try restarting the device.
|
||||
|
||||
### Perform a safe restart by using Cortana
|
||||
|
||||
The safest way to restart the HoloLens is by using Cortana. This is generally a great first-step when experiencing an issue with HoloLens:
|
||||
|
||||
1. Put on your device
|
||||
1. Make sure it’s powered on, a user is logged in, and the device is not waiting for a password to unlock it.
|
||||
1. Say “Hey Cortana, reboot” or "Hey Cortana, restart."
|
||||
1. When she acknowledges she will ask you for confirmation. Wait a second for a sound to play after she has finished her question, indicating she is listening to you and then say “Yes.”
|
||||
1. The device will now restart.
|
||||
|
||||
### Perform a safe restart by using the power button
|
||||
|
||||
If you still can't restart your device, you can try to restart it by using the power button:
|
||||
|
||||
1. Press and hold the power button for five seconds.
|
||||
1. After one second, you will see all five LEDs illuminate, then slowly turn off from right to left.
|
||||
1. After five seconds, all LEDs will be off, indicating the shutdown command was issued successfully.
|
||||
1. Note that it’s important to stop pressing the button immediately after all the LEDs have turned off.
|
||||
1. Wait one minute for the shutdown to cleanly succeed. Note that the shutdown may still be in progress even if the displays are turned off.
|
||||
1. Power on the device again by pressing and holding the power button for one second.
|
||||
|
||||
### Perform a safe restart by using Windows Device Portal
|
||||
|
||||
> [!NOTE]
|
||||
> To do this, HoloLens has to be configured as a developer device.
|
||||
> Read more about [Windows Device Portal](https://docs.microsoft.com/windows/mixed-reality/using-the-windows-device-portal).
|
||||
|
||||
If the previous procedure doesn't work, you can try to restart the device by using [Windows Device Portal](https://docs.microsoft.com/windows/mixed-reality/using-the-windows-device-portal). In the upper right corner, there is an option to restart or shut down the device.
|
||||
|
||||
### Perform an unsafe forced restart
|
||||
|
||||
If none of the previous methods are able to successfully restart your device, you can force a restart. This method is equivalent to pulling the battery from the HoloLens. It is a dangerous operation which may leave your device in a corrupt state. If that happens, you'll have to flash your HoloLens.
|
||||
|
||||
> [!WARNING]
|
||||
>Some information relates to prereleased product which may be substantially modified before it's commercially released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
|
||||
> This is a potentially harmful method and should only be used in the event none of the above methods work.
|
||||
|
||||
The Advanced Recovery Companion is a new app in Microsoft Store that you can use to restore the operating system image to your HoloLens device.
|
||||
1. Press and hold the power button for at least 10 seconds.
|
||||
|
||||
When your HoloLens 2 is unresponsive, not running properly, or is experiencing software or update problems, try these things in order:
|
||||
- It’s okay to hold the button for longer than 10 seconds.
|
||||
- It’s safe to ignore any LED activity.
|
||||
1. Release the button and wait for two or three seconds.
|
||||
1. Power on the device again by pressing and holding the power button for one second.
|
||||
If you’re still having problems, press the power button for 4 seconds, until all of the battery indicators fade out and the screen stops displaying holograms. Wait 1 minute, then press the power button again to turn on the device.
|
||||
|
||||
1. [Restart](#restart-hololens-2) the HoloLens 2.
|
||||
2. [Reset](#reset-hololens-2) the HoloLens 2.
|
||||
3. [Recover](#recover-hololens-2) the HoloLens 2.
|
||||
|
||||
>[!IMPORTANT]
|
||||
>Resetting or recovering your HoloLens will erase all of your personal data, including apps, games, photos, and settings. You won’t be able to restore a backup once the reset is complete.
|
||||
|
||||
## Restart HoloLens 2
|
||||
|
||||
A device restart can often "fix" a computer issue. First, say "Hey Cortana, restart the device."
|
||||
|
||||
If you’re still having problems, press the power button for 4 seconds, until all of the battery indicators fade out. Wait 1 minute, then press the power button again to turn on the device.
|
||||
|
||||
If neither of those things works, force restart the device. Hold down the power button for 10 seconds. Release it and wait 30 seconds, then press the power button again to turn on the device.
|
||||
|
||||
## Reset HoloLens 2
|
||||
|
||||
If the device is still having a problem after restart, use reset to return the HoloLens 2 to factory settings.
|
||||
|
||||
To reset your HoloLens 2, go to **Settings > Update > Reset** and select **Reset device**.
|
||||
## Reset to factory settings
|
||||
|
||||
>[!NOTE]
|
||||
>The battery needs at least 40 percent charge to reset.
|
||||
|
||||
## Recover HoloLens 2
|
||||
If your HoloLens is still experiencing issues after restarting, try resetting it to factory state. Resetting your HoloLens keeps the version of the Windows Holographic software that’s installed on it and returns everything else to factory settings.
|
||||
|
||||
If the device is still having a problem after reset, you can use Advanced Recovery Companion to flash the device with a new image.
|
||||
If you reset your device, all your personal data, apps, and settings will be erased. Resetting will only install the latest installed version of Windows Holographic and you will have to redo all the initialization steps (calibrate, connect to Wi-Fi, create a user account, download apps, and so forth).
|
||||
|
||||
1. Launch the Settings app, and then select **Update** > **Reset**.
|
||||
1. Select the **Reset device** option and read the confirmation message.
|
||||
1. If you agree to reset your device, the device will restart and display a set of spinning gears with a progress bar.
|
||||
1. Wait about 30 minutes for this process to complete.
|
||||
1. The reset will complete and the device will restart into the out-of-the-box experience.
|
||||
|
||||
## Re-install the operating system
|
||||
|
||||
If the device is still having a problem after rebooting and resetting, you can use a recovery tool on your computer to reinstall the HoloLens' operating system and firmware.
|
||||
|
||||
HoloLens (1st gen) and HoloLens 2 use different tools but both tools will auto-detect your HoloLens and install new software.
|
||||
|
||||
All of the data HoloLens needs to reset is packaged in a Full Flash Update (ffu). This is similar to an iso, wim, or vhd. [Learn about FFU image file formats.](https://docs.microsoft.com/windows-hardware/manufacture/desktop/wim-vs-ffu-image-file-formats)

# Restart, reset, or recover HoloLens
|
||||
|
||||
Here are some things to try if your HoloLens is unresponsive, isn’t running well, or is experiencing software or update problems.
|
||||
|
||||
## Restart your HoloLens
|
||||
|
||||
If your HoloLens isn’t running well or is unresponsive, try the following things.
|
||||
|
||||
First, try restarting the device: say, "Hey Cortana, restart the device."
|
||||
|
||||
If you’re still having problems, press the power button for 4 seconds, until all of the battery indicators fade out. Wait 1 minute, then press the power button again to turn on the device.
|
||||
|
||||
If neither of those things works, force restart the device. Hold down the power button for 10 seconds. Release it and wait 30 seconds, then press the power button again to turn on the device.
|
||||
|
||||
## Reset or recover your HoloLens
|
||||
|
||||
If restarting your HoloLens doesn’t help, another option is to reset it. If resetting it doesn’t fix the problem, the Windows Device Recovery Tool can help you recover your device.
|
||||
|
||||
>[!IMPORTANT]
|
||||
>Resetting or recovering your HoloLens will erase all of your personal data, including apps, games, photos, and settings. You won’t be able to restore a backup once the reset is complete.
|
||||
|
||||
## Reset
|
||||
|
||||
Resetting your HoloLens keeps the version of the Windows Holographic software that’s installed on it and returns everything else to factory settings.
|
||||
|
||||
To reset your HoloLens, go to **Settings** > **Update** > **Reset** and select **Reset device**. The battery will need to have at least a 40 percent charge remaining to reset.
|
||||
|
||||
## Recover using the Windows Device Recovery Tool
|
||||
|
||||
Before you use this tool, determine if restarting or resetting your HoloLens fixes the problem. The recovery process may take some time, and the latest version of the Windows Holographic software approved for your HoloLens will be installed.
|
||||
|
||||
To use the tool, you’ll need a computer running Windows 10 or later, with at least 4 GB of free storage space. Please note that you can’t run this tool on a virtual machine.
