--- name: vr-ar-650a60cd1508 description: "VR/AR development principles. Comfort, interaction, performance requirements." risk: unknown source: community date_added: "2026-02-27" --- # VR/AR Development > Immersive experience principles. --- ## 1. Platform Selection ### VR Platforms | Platform | Use Case | |----------|----------| | **Quest** | Standalone, wireless | | **PCVR** | High fidelity | | **PSVR** | Console market | | **WebXR** | Browser-based | ### AR Platforms | Platform | Use Case | |----------|----------| | **ARKit** | iOS devices | | **ARCore** | Android devices | | **WebXR** | Browser AR | | **HoloLens** | Enterprise | --- ## 2. Comfort Principles ### Motion Sickness Prevention | Cause | Solution | |-------|----------| | **Locomotion** | Teleport, snap turn | | **Low FPS** | Maintain 90 FPS | | **Camera shake** | Avoid or minimize | | **Rapid acceleration** | Gradual movement | ### Comfort Settings - Vignette during movement - Snap vs smooth turning - Seated vs standing modes - Height calibration --- ## 3. Performance Requirements ### Target Metrics | Platform | FPS | Resolution | |----------|-----|------------| | Quest 2 | 72-90 | 1832x1920 | | Quest 3 | 90-120 | 2064x2208 | | PCVR | 90 | 2160x2160+ | | PSVR2 | 90-120 | 2000x2040 | ### Frame Budget - VR requires consistent frame times - Single dropped frame = visible judder - 90 FPS = 11.11ms budget --- ## 4. Interaction Principles ### Controller Interaction | Type | Use | |------|-----| | **Point + click** | UI, distant objects | | **Grab** | Manipulation | | **Gesture** | Magic, special actions | | **Physical** | Throwing, swinging | ### Hand Tracking - More immersive but less precise - Good for: social, casual - Challenging for: action, precision --- ## 5. Spatial Design ### World Scale - 1 unit = 1 meter (critical) - Objects must feel right size - Test with real measurements ### Depth Cues | Cue | Importance | |-----|------------| | Stereo | Primary depth | | Motion parallax | Secondary | | Shadows | Grounding | | Occlusion | Layering | --- ## 6. Anti-Patterns | ❌ Don't | ✅ Do | |----------|-------| | Move camera without player | Player controls camera | | Drop below 90 FPS | Maintain frame rate | | Use tiny UI text | Large, readable text | | Ignore arm length | Scale to player reach | --- > **Remember:** Comfort is not optional. Sick players don't play. ## When to Use This skill is applicable to execute the workflow or actions described in the overview. ## Limitations - Use this skill only when the task clearly matches the scope described above. - Do not treat the output as a substitute for environment-specific validation, testing, or expert review. - Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing. --- Source attribution: DorianGallo Original contribution (preserved): https://github.com/DorianGallo/antigravity-awesome-skills-local/blob/a2a0d2562db3605276a7229bbb822c53b6e0ef30/plugins/antigravity-awesome-skills-claude/skills/game-development/vr-ar/SKILL.md License: MIT + CC-BY-4.0 License information: https://creativecommons.org/licenses/by/4.0/ Original upstream instructions; downloaded from Dave AI. ## Upstream license notice MIT License Copyright (c) 2026 Antigravity User Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
