This can greatly accelerate input with less effort for the user. Rather than typing with air taps, voice dictation can be more efficient to enter text into an app. If you want a complete list, just say, 'Show all commands' anytime. You can also use the head gaze cursor to look around and reveal the voice tooltips for each button in front of you. To learn about what commands you can use, gaze at an object and say, 'what can I say?'. Some commands, like the commands for fast manipulation above, can be hidden. Or you could look at a holographic part on a complex machine and say: 'give me more information about this'. On HoloLens 2, you can also create more natural interactions in combination with eye-gaze, which implicitly provides contextual information about what you are referring to.įor example, you could look at a hologram and say 'put this' and then look over where you want to place it and say 'over here'. These voice commands work on app windows and 3D objects you've placed in the world. There are many voice commands you can say while gazing at a hologram to quickly do manipulation tasks.

Voice commands for fast hologram manipulation You can even say 'select' with your hands at your side. 'Select' is enabled by a low-power keyword detection algorithm, which means you can say it anytime with minimal battery life impact. You'll hear a sound and see a tooltip with 'select' appear as confirmation. This behaves the same as an air tap on HoloLens, pressing the select button on the HoloLens clicker, or pressing the trigger on a Windows Mixed Reality motion controller. Some voice commands don't require a target at all, such as 'go to start' or 'Hey Cortana.'Įven without specifically adding voice support to your app, your users can activate holograms simply by saying the system voice command 'select'. It may not even be required to show any gaze cursor ('see it, say it'). When you're using voice commands, head or eye gaze is the typical targeting mechanism, whether with a cursor to 'select' or to channel your command to an application you're looking at. On HoloLens, speech recognition will always function in the Windows display language configured in your device Settings. Voice input is powered by the same engine that supports speech in all Universal Windows Apps. Voice is especially good at traversing complex interfaces, because it lets users cut through nested menus with one command. Voice input can be a natural way to communicate your intent. It allows you to directly command a hologram without having to use hand gestures. Voice is one of the key forms of input on HoloLens.
