System keyboard

A Unity application can invoke the system keyboard at any time. Note that the system keyboard will behave according to the target platform's capabilities, for example the keyboard on HoloLens 2 would support direct hand interactions, while the keyboard on HoloLens (1st gen) would support GGV¹.

How to invoke the system keyboard

    public TouchScreenKeyboard keyboard;

    ...

    public void OpenSystemKeyboard()
    {
        keyboard = TouchScreenKeyboard.Open("", TouchScreenKeyboardType.Default, false, false, false, false);
    }

How to read the input

    public TouchScreenKeyboard keyboard;

    ...

    private void Update()
    {
        if (keyboard != null)
        {
            keyboardText = keyboard.text;
            // Do stuff with keyboardText
        }
    }
