This page is for **field workers** executing a procedure on the HoloLens. By the end of it, you will know how to use the visual guidance attached to each step: the media panel for images and video, and the 3D models that appear in your physical workspace. Both media and models are **step-specific** — as you move between steps, each step shows only its own content. What appears, and how you can interact with it, depends on how the procedure was authored. ## The Media Panel Media panel displaying an attached video for the current step with a play button The **Media panel** appears next to the step panel only when the current step has an image or video attached. If a step has no media, the panel simply doesn't appear. ### When the Step Has an Image The image is displayed in the panel and stays visible while you are on that step. There are no playback controls. ### When the Step Has a Video The panel shows a video player with a **Play / Pause** control and a **Mute / Unmute** (speaker) control. * The video **starts playing automatically** when you enter the step, and plays **in a continuous loop**. * Select **Pause** to stop on the current frame; select **Play** to resume looping. * Select the **speaker icon** to toggle audio on or off. When you move to another step, the media panel refreshes: a new video auto-plays, a new image displays statically, and if the step has no media the panel disappears. This works the same on every step type, including choice steps. ## 3D Models in Your Workspace Procedure view showing 3D models placed in the physical environment alongside the step main panel If the current step includes 3D models, they appear directly in the physical space at their saved positions, anchored relative to the QR code you confirmed — see [Anchoring & QR Codes](/frontline/overview/concepts/anchoring-and-qr-codes). If a step has no models, none appear. You cannot add new models or change model settings. How much you can interact with each model depends on how it was configured: ### View-Only Models Some models are fixed visual references. You can see the model at its position, but you cannot grab, move, or manipulate it. ### Movable (Interactable) Models A repositioned interactable model showing a reset control to return it to its original position Other models can be **grabbed and moved** — useful for holding a reference part next to the real one. Moving a model affects only your current session; the procedure's saved configuration is unchanged. A **reset control** lets you return a moved model to its original position. ### Ghost Reference A moved model with a reset control hovered near the ghost placeholder remaining at the original position Some movable models leave a **ghost** — a shadow that stays at the original position when you move the model, showing you the intended placement. If no ghost appears when you move a model, that model wasn't set up with one; only the relocated model is visible. ### Animations Animated models play automatically according to their saved settings — playback mode (loop, once, ping-pong), direction, and speed are fixed. You cannot change the animation, adjust its speed, or pause it. Models without animation stay static. Moved a model and lost track of things, or panels out of reach? Open the palm side menu and use **Reposition** to bring panels back in front of you — see [Follow the Steps](/frontline/hololens/operate/follow-steps). *** **Next:** [Complete and Sign Off](/frontline/hololens/operate/complete-and-sign-off)
