HoloLens 2 gestures for authoring and navigating in Dynamics 365 Guides
Hand-tracking in Microsoft HoloLens 2 provides instinctual interactions for authors. You can select and position holograms by using direct touch, just as if they were real objects. You can also use hand rays to interact with holograms that are out of reach.
Basic actions and gestures to know
To author or navigate in HoloLens 2, you must know how to do these actions and gestures:
Touch. With HoloLens 2 and Dynamics 365 Guides, you can reach out and touch or grab holograms. This approach is the easiest and most intuitive way to author guides. As the following animation shows, when HoloLens sees your hand, a floating pointer (similar to a mouse pointer) appears near the tip of your index finger to help you target elements.
Use touch interaction to work with parts that you've placed in the world. In Dynamics 365 Guides, instruction cards (Step cards) are meant to be kept out of the way so that they are out of reach for touch interaction.
Hand ray. To use a hand ray, hold your hand in front of you, with your palm facing away. A laser pointer (hand ray) appears. After you target an item with your hand ray, you can act on that target in different ways, as described later in this topic.
Gaze. Gaze is the act of selecting an item or targeting an object with the HoloLens. If the item has a selection box or circle (gaze/dwell button), you can select the item by gazing at it. The item is selected when the box or circle is filled. Often, you will use gaze and air tap together. When you gaze, turn your whole head, not just your eyes. The pointer will follow.
Air tap. Air tap is a gesture that's equivalent to a "click" with a mouse. Hold your hand straight out in front of you in a loose fist, point your index finger straight up toward the ceiling, tap your finger down, and then quickly raise it back up again.
Air tap and hold. Start by air tapping, but keep your finger down instead of raising it back up.
It's also important to know about the gesture frame. HoloLens 2 has sensors that can see a few feet to each side of you. When you use gestures, you must keep them inside that frame. Otherwise, HoloLens won't see them. As you move around, the frame moves with you. When your hand is inside the frame, a hand ray will appear from your palm. If HoloLens can't see your hands, and you're looking at a user interface (UI) element, you'll see the gaze pointer in the center of your display.
Work with close-up UI elements and holograms by using touch
For close-up UI elements and holograms, you can just reach out and touch or grab them with your hands. When your hand gets close enough to touch or grab a hologram, a visual appears around the control to let you know what that control does.
Select a button
- Push the button with your index finger.
Select a hologram
Touch the hologram with your index finger. The controls will appear.
Move a hologram
Grab the large white sphere in the center of the controls with your hands, and move it where you want. The sphere will light up based on where your index finger is in relation to it.
Rotate a hologram
Pinch one of the blue spheres (rotation controls), and rotate it the way that you want. Arrows appear around the rotation controls to show which direction they can be rotated.
Change the size of a hologram
Pinch the blue dial (Scale control) on the right side of the part. A slider track appears above and below the Scale control to show scaling up or down.
Edit a hologram
Touch the Edit hologram button with your finger, and then touch the command that you want.
Work with far-away UI elements and holograms by using hand rays and gaze
You can use hand rays to work with UI elements and holograms from a distance. You can use gaze to work with the instruction card from a distance, but you can't use it to manipulate holograms.
When you author a guide, if your hand is visible, hand rays are enabled and gaze is disabled. To use gaze, place your hands at your sides, so that the HoloLens 2 device can't see them.
Select a button or UI element with a hand ray
Point your hand ray at the object to target it.
Follow one of these steps:
Air tap to select the object.
If there is a selection box or circle, hold your hand ray on it until it's selected.
Manipulate a hologram by using a hand ray
Point your hand ray at the object to target it. Controls appear around the hologram.
Follow one of these steps:
To move the hologram, air tap and hold the hand ray, move the hologram where you want it, and then release.
To rotate the hologram, air tap and hold one of the blue spheres, rotate the hologram, and then release.
To change the size of a hologram, air tap and hold the Scale control. While you hold the control, move it up or down along the slider track.
To edit the hologram, air tap the Edit button, and then air tap the selections that you want.
Select an item on the instruction card by using gaze
Put your hands at your sides, and gaze at the button or UI element.
Continue to gaze until the button is filled.
Open the Start menu
On HoloLens 2, you can use either one hand or two hands to open the Start menu. If you're ever unsure what to do, opening the Start menu is a good way to get reoriented.
Open the Start menu with one hand
Hold out one of your hands with the palm facing up, and look at your wrist. You should see a holographic Microsoft Windows logo.
With the hand that you're holding out, touch your index finger to your thumb in a pinching motion.
Open the Start menu with two hands
Hold out one of your hands with the palm facing up, and look at your wrist. You should see a holographic Windows logo.
With the index finger of your other hand, touch the Windows logo.
