documentation
Our HoloLens example scenes include simple commands that you can invoke with your voice or a connected Bluetooth keyboard. Please note that voice commands only work if your HoloLens has an internet connection.
We provide prefabs for speech inputs and key codes that trigger VisionLib events. These inputs are listed in the table below. The prefabs are located at VisionLib SDK - HoloLens/Prefabs/Input and are used in our HoloLens example scenes. There, the prefabs are located under the Input GameObject in the hierarchy.
You can set up your own custom speech or keyboard input using WindowsSpeechInput and KeyboardInput.
