Ar Vr Design

AR Design Principles

• World-anchored: UI elements attached to real-world surfaces.
• Minimal HUD: Don't clutter the real-world view.
• Lighting-aware: UI adapts to environment brightness.
• Occlusion: Virtual objects hidden behind real objects.

VR Design Principles

• Comfort first: Avoid motion sickness. Fixed reference points.
• Spatial audio: Sound direction matches visual position.
• Readable text: Minimum 1.5° angular size (~32px at arm's length).
• Interaction range: Content within arm's reach for interaction.

UI Placement

• Head-locked: Moves with user's head. Use sparingly (HUD, notifications).
• World-locked: Fixed in 3D space. Use for spatial content.
• Body-locked: Follows user but with lag. Use for menus.
• Gaze-following: Faces the user. Use for information panels.

Input Methods

• Gaze + dwell (look at button for 1-2s to activate).
• Hand tracking (pinch, grab, point).
• Controller (ray-casting, trigger, grip).
• Voice commands (hands-free interaction).
