Capturing a Procedure
Before you capture your procedure with Vuforia Capture, you’ll want to make sure that you’ve documented the process you will use to create work instruction procedures. For more information, see Create Procedure Workflow in the Vuforia Expert Capture success path.
Prepare your environment before you begin your Capture session. Remove movable objects, make sure machines are configured appropriately, and remove clutter that may not be representative of the ideal scenario.
Plan the path of how you will move through the environment before you begin.
Make sure others are aware that you are conducting a Capture to avoid interference while recording.
Before you start your Capture session, make sure that your camera is positioned properly.
Use short, action-oriented instructions, and speak in a clear and natural tone of voice. Treat the Capture session as if you were instructing or guiding another person on how to successfully complete the procedure from start to finish.
Make an intentional effort to ‘look with your head’ rather than your eyes to make sure you’re capturing the appropriate view.
Video is continuously recorded throughout a Capture session (unless deliberately paused)
Don’t worry about making it absolutely perfect—you’ll be able to edit it in Vuforia Editor.
Pause the capture to reduce content that is not core or relevant to authoring the work procedure (for example, a long wait time between steps).
The “Pause capture" command inserts a new step once you resume.
HoloLens 2 and Magic Leap devices:
Create location markers at any point during a Capture session to associate a step with a physical place in the environment. To make sure your locations show up in the right place, Capture automatically scans your environment throughout your Capture session and generates a Vuforia Area Target to make sure users see the location markers in the correct place. To make sure an optimal Area Target is captured, use the following guidance.
Make sure lighting conditions are not too dark.
Don’t try to create procedures with large physical gaps between steps; this can cause imperfections in the Area Target.
Avoid capturing shiny, transparent, or dark colored objects if possible.
If this is unavoidable, make sure to approach these objects slowly from an angle and try to identify irregular edges on the object to focus on. If possible, use 3D Scanning spray to coat your objects with a layer that can be captured within a scan.
Be sure to move slowly and look around your surroundings in between steps to ensure that the scan is representative of your environment.
The area you are capturing should be no larger than 15,000 square feet.
Locations aren’t required, but if you do choose to use them, the current step you’re on will be associated to that anchor behind the scenes. Additionally, any future steps are also associated to that location until another location is placed. All step information is displayed where that location was placed upon Playback. If you do not use locations, the steps will float in front of the user instead of being associated to a particular spatial location.
Use bookmarks to mark significant moments during the Capture session. Bookmarks are used during editing as reference points to revisit during the authoring process.
Ensure that the device battery is fully charged before beginning a Capture session.
Regularly remove old Capture files from the device to ensure there’s sufficient space for new captures (~100MB per minute).
Adjust the camera to ensure that the microphone is not in view of the camera.
Also make sure ensure that the camera is adjusted to capture their hands or any other desirable surface or area that you want included in your Capture session.

Device thermal conditions:
Avoid using the device for extended period of times (over 30 minutes).
Avoid repeated usage to generate multiple Captures in a row.
If you notice your device becoming overheated, let the device rest for 10–15 minutes to cool down.
