HoloLens provides the ability to work with accessories via Bluetooth. Two common scenarios for using accessories are substitutes for the air-tap gesture and the virtual keyboard. For this, the two most common accessories are the HoloLens Clicker and Bluetooth keyboards. Microsoft HoloLens includes a Bluetooth 4.1 radio and supports Bluetooth HID and Bluetooth GATT profiles.
Pairing a Bluetooth peripheral with Microsoft HoloLens is similar to pairing a Bluetooth peripheral with a Windows 10 desktop or mobile device:
The HoloLens Clicker is the first peripheral device built specifically for HoloLens and is included with the HoloLens Development Edition. The HoloLens Clicker allows a user to click and scroll with minimal hand motion as a replacement for the air-tap gesture. It is not a replacement for all gestures. For instance, bloom and resize or move gestures use hand motions. The HoloLens clicker is an orientation sensor device with a simple button. It connects to the HoloLens using Bluetooth Low Energy (BTLE).
To select a hologram, gaze at it, and then click. Orientation of the clicker does not matter for this operation. To scroll or pan, click and hold, then rotate the Clicker up/down or left/right. While scrolling, you’ll reach the fastest speed with as little as +/- 15° of wrist rotation. Moving more will not scroll any faster.
There are two LEDs inside the Clicker:
You can expect 2 weeks or more of regular use on a full charge (i.e., 2-3 hours on a wall charger). When the battery is low, the amber LED will blink 10 times over a 5-second period if you press the button or wake it from sleep. The amber LED will blink more rapidly over a 5-second period if your Clicker is in critically low battery mode.
English language Qwerty Bluetooth keyboards can be paired and used anywhere you can use the holographic keyboard. Getting a quality keyboard makes a difference, so we recommend the Microsoft Universal Foldable Keyboard or the Microsoft Designer Bluetooth Desktop.
You can use a controller with apps and games that specifically enable gamepad support. Gamepads cannot be used to control the HoloLens user interface.
Xbox Wireless Controllers that come with the Xbox One S or sold as accessories for the Xbox One S feature Bluetooth connectivity that enables them to be used with a HoloLens. The Xbox Wireless Controller must be updated before it can be used with HoloLens.
Other brands of Bluetooth gamepads may work with the HoloLens, but support will vary by application.
As long as the peripheral supports either the Bluetooth HID or GATT profiles, it will be able to pair with HoloLens. Other Bluetooth HID and GATT devices besides keyboard, mice, and the HoloLens Clicker may require a companion application on Microsoft HoloLens to be fully functional.
Unsupported peripherals include:
This will turn off the RF components of the Bluetooth radio and disable all Bluetooth functionality on Microsoft HoloLens.
