- Collaborate with live annotation tools: label, point arrows and draw
- Workspace moves with you and adapts to your work environment
Assist is available through the "Featured Apps" menu option available starting with Magic Leap OS 1.1.0. Note: "Featured Apps" opens a webpage in the browser. You may need to enable the "Install unknown apps" permission for the browser to install Assist after downloading it.
Assist on Magic Leap 2
A home menu will display when the Magic Leap 2 powers on. Use the controller to interact with the menu. Your controller will cast a ray to show where it is pointed.
Select Featured Apps
Scroll through the home menu to locate Featured Apps. Point your controller ray at Featured Apps and press the trigger button to select it. A web browser will appear displaying featured applications for the Magic Leap 2.
Locate and select Assist from the list of featured applications. Selecting Assist will download and install the application. When Assist is finished downloading, it will appear as an item in the home menu.
Locate Assist in the home menu. Select Assist to launch the application.
The Magic Leap 2 controller is used to navigate Assist. The following actions are mapped to the controller:
- Grab Object (Object Targeted)
- Draw (Drawing Tool Active)
- Pin (Pin Tool Active)
- Place Arrow (Arrow Tool Active)
- Erase (Eraser Tool Active)
- Take Photo (Photo Capture Feature Active)
- Drop Annotation Tool (Annotation Tool Active)
- Open Object Context Menu (Object Targeted)
- Hide/Reveal Navigation Menu
- Pauses Assist and opens Magic Leap 2 Home Menu
- Move Annotation Cursor (Annotation Tool Active)
- Move Object (Object Selected)
- Scale Object (Object Selected)
- Rotate Object (Object Selected)
After Assist loads, you will see the menu appear. For first time users, this happens after a brief tutorial.
The menu contains the following:
Call control buttons are disabled when a session is not active. A session is considered active when you are connected with a web-user in a live chat.
When a session is active, the following call controls are accessible:
- Camera On/Off
- End Call
You can open and close submenus by selecting buttons on the menu. Point your controller ray at a menu button and select it by pressing and releasing the trigger button.
Only one menu button can be active at a single time (unless submenus are undocked, see Undocking Submenus). For example, if you open the Session panel and then select the Annotate button, the Session panel will automatically close and the Annotate panel will open in its place.
The Workspace is a body-relative, invisible sphere that houses your menu, tools, and files.
The Workspace travels with you, acting as a mobile workstation, providing easy access to your menu, tools and files regardless of where you are. You are always at the center of the Workspace and when you move, it moves with you.
Configurable for Any Task
The Workspace is highly configurable and can be customized to compliment the task at hand. Your menu, submenu panels, and files can be positioned to accommodate the physical constraints of your environment (see 7.0 Customizing Navigation).
Moving The Menu
To move the menu, hover over the menu with your controller ray and select the move button located below the center of the menu. With the trigger button pressed, move the controller to reposition the menu.
When moving the menu around the Workspace, a dot pattern is visible indicating the surface of the Workspace.
Submenus, such as Annotate, can be undocked from the menu. Hover over the submenu panel and select the move button. With the trigger button pressed, move the controller to undock the submenu from the menu.
The undocked submenu panel can be positioned anywhere on the Workspace.
Customizing Your Workspace
By undocking submenus, you can have multiple submenu panels open at a single time. This can be helpful, for example, if you would like to have both the Annotate panel and the Session panel open at the same time to assist you in performing a task.
Body-Relative or World-Relative
By default, your menu and files are body-relative and attached to the Workspace. Your menu and files can be made world-relative by undocking them from the Workspace and placing them in a world-relative position. If an object is world-relative, then it remains in a fixed position in your environment rather than traveling with you on the Workspace.
To make your menu (or a submenu panel) world-relative, hover over the menu and select the move button. With the trigger button pressed, push or pull the menu off of the Workspace sphere. As the menu detaches from the Workspace, you will notice that the menu is no longer surrounded by dots. When the menu is undocked from the Workspace, it remains world-relative in a fixed position in the environment.
Resetting the Menu
You can hide or reset the menu by pressing the menu button on the controller. Pressing the menu button once hides the menu. Pressing the menu button a second time resets the menu. Resetting the menu automatically closes and docks any submenus that may have been active or undocked.
Start A Session
Invite A Participant
The heart of Assist is a live, collaborative session between you and a web-user. You are the session host and the web-user is the participant. As the host, you initiate the session by inviting a participant.
Enter the web-user’s email address by selecting the Participant Email field. A keyboard will open. Use the keyboard to fill in the email address. Select done to close the keyboard. Select the Your Name field, enter your name, and then close the keyboard.
When both fields are complete, select the Invite button. A session invitation will be emailed to the web-user.
A confirmation message is displayed letting you know the invitation has been sent. Select the Next button to proceed.
If you need to resend the invitation or send an invitation to a new participant, select the Send New Invitation button.
Scan Your Environment
Scan your environment by looking around in all directions. Scanning creates a digital mesh of your environment that is shared with the web-user in the Assist Web App.
The mesh visualization is automatically turned on when advancing to this panel. You can turn the mesh visualization off by selecting the Mesh button in the menu. Scanning continues in the background even if the mesh view is turned off.
Accept Join Request
A notification appears when the web-user requests to join the session. You must accept the web-user’s request for the session to begin.
Connect Live with Video Chat
When the session is connected, a live video and audio feed of the web-user appears in the Session panel.
When a session is live, the web-user can hear an audio feed of you and see a camera feed broadcast from your Magic Leap 2. The live camera feed allows the web-user to see your environment from your perspective.
The live video chat continues even if you close the Session panel.
During a session, the call control buttons on the menu are enabled. You can mute/unmute your audio, turn your camera feed on/off, and end the session call at any time.
Objects & Files
Receiving Objects and Files
The web-user can send you objects and files such as schematics, instructions, or 3D models to help assist you with tasks in your environment.
When the web-user sends you a file, a notification displays on the Workspace. Select accept and the file will appear.
The Object Menu displays information about the object and provides access to actions such as delete and scale to actual size. To open the Object Menu, hover over the object and select the menu icon. You can also open the Object Menu by hovering over the object and pressing the bumper button.
Animating Special Objects
Special objects can be disassembled, allowing you to see all of the object's parts and better understand the object’s construction. To disassemble or assemble a special object, hover over the object and select the Assemble/Disassemble button or open the Object Menu and select Assemble/Disassemble.
Move, Scale and Rotate Objects
To move an object, hover over it, press the trigger button, and move the controller while holding the trigger button. Release the trigger button to place the object.
To scale an object, hover over the object, press and hold the trigger button, and press left on the touchpad to scale the object down or right on the touchpad to scale it up.
To rotate an object, select the object, and rotate clockwise or counterclockwise on the touchpad while holding the trigger button.
Direct Object Manipulation
Direct object manipulation gives you the ability to move and rotate digital objects as if they were physical objects.
Objects can be directly manipulated by placing your controller on, or in close proximity to, the digital object. When your controller is close to the object, the controller ray is replaced with a special cursor. Press and hold the trigger button to grab the object. While holding the trigger button you can move or rotate the object free-form, as if you were holding it in your hand. Release the trigger button to place the object.
The files folder can be accessed by selecting the Files button from the menu. The files folder contains a library of pre-loaded 3D objects and 2D assets. The files folder also contains photos taken with the capture feature.
Files can be opened by dragging and dropping them onto the Workspace.
Hover over the file and press the trigger button to select it. While holding the trigger button, drag the file onto the Workspace, and then release the trigger button. The file opens where it is dropped.
Photo Capture Feature
The photo capture feature allows you to take photos during a session. To activate the photo capture feature, select the Capture button on the menu. When the photo capture feature is active, a head-locked viewfinder appears.
Look at the area where you would like to capture a photo. Press the bumper button to take a photo. The photo captures both the real-world and digital content within the viewfinder. The photo is automatically saved in the files folder.
The photo capture feature is only available when a session is active and when your video feed is on.
To exit the capture feature, select the Capture button in the menu.
Open the files folder by selecting the Files button from the menu. Select the Photos folder in the files panel. The Photos folder contains all photos created using the capture feature.
A preview image is displayed for each photo. Photos are named with the time and date they were taken. Photos can be opened by dragging and dropping them onto the Workspace.
Photos generated with the capture feature can be sent to the web-user. A share icon appears on each photo thumbnail.
Select the share icon to send the photo to the web-user. A dialogue box will display confirming you would like to send the photo.
Mark Up Your Space
Annotations are visual communication tools. Both you and the web-user can annotate directly in your space using digital tools.
Annotation tools can be accessed by opening the Annotate submenu panel. The following annotation tools are available: Draw, Pin, Arrow, Eraser, and Color Palette.
You can place arrows to direct attention or guide someone through a large space. You can use pins to mark components or label detailed parts on a piece of machinery. You can use drawings to highlight important areas or communicate
Using Annotation Tools
When an annotation tool is active, the controller ray is replaced with a custom cursor. A label is mapped to the touchpad of the controller displaying the name of the active tool (ex: Draw, Pin, Arrow, Eraser).
The user can “drop” an active tool at any time by pressing the bumper button on the controller. An active tool can also be “dropped” or unselected by selecting the tool button a second time.
Swipe to Customize Cursor Position
The custom cursor (ex: crosshair) position can be adjusted. Swipe up on the trackpad to move the cursor farther away from the controller. Swipe down on the trackpad to move the cursor closer to the controller. Adjusting the position can help extend your reach.
The color pallet allows you to select a color for your annotations. The selected color is used when creating drawings, placing pins, or placing arrows.
The current active color is displayed at the center of the color pallet wheel and is reflected in the tool icons.
When the color pallet is active, it replaces the Annotate panel. Select the X icon to close the color pallet.
Drawing tools can be used to create freeform lines in space. There are two drawing tools available: thick and thin.
When a drawing tool is active, a crosshair appears floating in front of your controller.
Place the crosshair point where you would like to start drawing. Then press and hold the trigger while moving the controller to draw. Releasing the trigger completes the drawing.
A pin is a physical marker with a label that can be used to identify objects in your space.
When the pin tool is active, a crosshair appears floating in front of your controller. Place the crosshair where you would like the pin tip to point. Then press and release the trigger to place the pin. Hover over the pin and select the form field to add a label.
The label is a helpful communication feature that is unique to pins. Imagine using pins to identify and label small parts on a piece of machinery.
Arrows are used to direct attention towards points of interest and as a wayfinding mechanism.
When the arrow tool is active, a crosshair appears floating in front of your controller. Place the crosshair where you would like the arrow tip to point. When you press the trigger button, the arrow appears with the point originating at the crosshair center. While holding the trigger, the user can move the controller to change the arrow’s length and direction. Releasing the trigger places the arrow.
The eraser can be used to delete individual objects.
When the eraser tool is active, a crosshair appears floating in front of your controller. Target individual pins, drawings, or arrows by hovering over the annotation. When the annotation is targeted, the crosshair turns red. Press and release the trigger button to erase the targeted annotation.
Delete All Annotations
Delete All (trash icon) removes all annotations from the session including annotations that were created by you and annotations created by the web-user.
Selecting the delete all button displays a confirmation message dialogue box. Annotations will not be deleted until confirmed through the dialogue box.
The tutorial can be accessed at any time through the Assist panel. To open the Assist panel, select the Assist icon from the menu. The tutorial tab is active by default when the Assist submenu panel opens.
