The FrontPlate responds to the proximity of the index fingertip using the Button_Box shader. The ButtonContent object contains front plate, text label and icon. Required to make any object touchable with articulated hand input. Unity audio source for the audio feedback clips. HoloLens gaze, gesture, and voice input and immersive headset motion controller input are directly handled by this script. Interactable Interactable handles various types of interaction states and events. This script sends events from hand press interaction to Interactable. The logic for the button movement with hand press interaction. Inspector propertiesīox Collider Box Collider for the button's front plate. If any proximity lights are found, the ProximityLight.Pulse method is called, which automatically animates shader parameters to display a pulse. The subtle pulse effect is triggered by the pressable button, which looks for ProximityLight(s) that live on the currently interacting pointer. In HoloLens 2 shell-style button, there are many visual cues and affordances to increase the user's confidence on interaction. When the fingertip touches the surface of the front plate, it shows a subtle pulse effect to give visual feedback of the touch point. When pushed with a finger, the front plate moves with the fingertip. There is additional highlighting of the fingertip position on the front plate surface. As a finger approaches or a cursor from gaze input targets the surface, the front plate's glowing border becomes visible. In the idle state, the button's front plate is not visible. To support both near and far interactions, it is recommended to use Interactable's OnClick event. These events will not fire in response to air-tap, hand-ray, or eye inputs, however. To leverage specific articulated hand input state information, you can use pressable buttons events - Touch Begin, Touch End, Button Pressed, Button Released. You can configure when the pressable button fires the OnClick event via the PhysicalPressEventRouter on the button. For example, you can set OnClick to fire when the button is first pressed, as opposed to being pressed and released, by setting Interactable On Click to Event On Press. This event gets triggered for different types of input methods such as gaze, air-tap, hand-ray, as well as physical button presses through the pressable button script. The events exposed in the prefab itself as well as the Interactable component can be used to trigger additional actions. The pressable buttons in the HandInteractionExample scene use Interactable's OnClick event to trigger a change in the color of a cube. These button prefabs are already configured to have audio-visual feedback for the various types of inputs, including articulated hand input and gaze. Simply drag PressableButtonHoloLens2 (Assets/MRTK/SDK/Features/UX/Interactable/Prefabs/PressableButtonHoloLens2.prefab) or PressableButtonHoloLens2Unplated (Assets/MRTK/SDK/Features/UX/Interactable/Prefabs/PressableButtonHoloLens2Unplated.prefab) into the scene. Then, drag PressableButtonUnityUI (Assets/MRTK/SDK/Features/UX/Interactable/Prefabs/PressableButtonUnityUI.prefab), PressableButtonUnityUICircular (Assets/MRTK/SDK/Features/UX/Interactable/Prefabs/PressableButtonUnityUICircular.prefab), or PressableButtonHoloLens2UnityUI (Assets/MRTK/SDK/Features/UX/Interactable/Prefabs/PressableButtonHoloLens2UnityUI.prefab) onto the Canvas. Set the Rect Transform component's X, Y, and Z scale to 0.001.Click 'Add NearInteractionTouchableUnityUI'.

How to use pressable buttons Unity UI based buttonsĬreate a Canvas in your scene (GameObject -> UI -> Canvas). Holograms that are displayed through a transparent plane can be unstable with HoloLens 2's Depth LSR stabilization.It is hard to understand when the event triggers.Icon and text are difficult to read with the physical environment.Transparent buttons are not recommended because of these usability and stability issues: It combines Interactable script with PressableButton script.įor HoloLens 2, it is recommended to use buttons with an opaque backplate. PressableButtonHoloLens2 (Assets/MRTK/SDK/Features/UX/Interactable/Prefabs/PressableButtonHoloLens2.prefab) is HoloLens 2's shell style button that supports the precise movement of the button for the direct hand tracking input. You can also use voice command to trigger the button. The baseline button supports all available input methods, including articulated hand input for the near interactions as well as gaze + air-tap for the far interactions. Unity grid system 2d.The Button (Assets/MRTK/SDK/Features/UX/Interactable/Prefabs/Button.prefab) is based on the Interactable concept to provide easy UI controls for buttons or other types of interactive surfaces.
