iPhone Raycaster and Cursor Control for Luxid Vue
How to use an iPhone as an on-screen pointer, when raycasting helps and how it compares with touch or mirroring.
What is phone-based raycaster control?
Raycaster control uses the phone’s movement to guide an on-screen pointer. Instead of reaching for a separate mouse, you point the handset toward the item you want to select and use the app’s interaction controls. It gives the iPhone a second job: phone in hand as a compact cursor controller, while the glasses remain the private display.
This is most helpful when the app interface is spread across a larger virtual workspace. A pointer can make selection feel more direct than repeated touch-and-look switching, especially when the phone is already in your hand.
Raycaster, touchpad, or mirror?
Choose raycasting when you want to point at an on-screen control. Choose a touchpad-style interaction when you prefer relative swipes and taps. Choose direct mirroring when you only need to see the iPhone’s existing screen and do not need the Luxid app workspace.
These are different interaction models rather than competing claims. The best choice depends on whether your task is selecting spatially arranged items, navigating with familiar gestures, or simply viewing the phone output.
- Pointing: raycaster control
- Gestures: touchpad-style control
- Simplest setup: direct display mirroring
A few setup habits improve control
Keep the phone movement small and deliberate, begin with a stable posture, and practice selecting a few large targets before navigating dense interfaces. If the pointer feels too sensitive, check the current app controls and make sure the phone has a steady connection.
Luxid’s iOS app provides pointer control alongside its browser and multi-screen features. The workflow does not require you to claim 3DoF anchoring on iOS; the glasses’ display and the app’s input features are the focus.
