VR/AR Game Design Guide

Design a VR or AR game experience for:

Platform: [META QUEST/PSVR2/PCVR/APPLE VISION PRO/AR MOBILE]
Experience Type: [SEATED/STANDING/ROOM-SCALE/MIXED REALITY]
Target Session Length: [MINUTES PER PLAY SESSION]
Locomotion Preference: [TELEPORT/SMOOTH/PHYSICAL/HYBRID]
Social Component: [SOLO/CO-OP/MULTIPLAYER/SPECTATOR]
Target Audience Comfort: [VR NEWCOMERS/EXPERIENCED/ENTHUSIAST]

Develop the design guide across these sections:

1. Spatial Design & Interaction Principles
Define the play space requirements and how the game adapts to different room sizes. Create the interaction model covering grab, point, gesture, gaze, and voice controls. Design the hand presence system ensuring the player's virtual hands feel natural and responsive. Build the object interaction physics with weight, resistance, and haptic feedback design. Define the UI placement strategy for menus, HUD elements, and world-space information. Create the onboarding sequence that teaches spatial interaction naturally.

2. Comfort & Motion Sickness Prevention
Establish the comfort rating system classifying every mechanic from comfortable to intense. Design the locomotion system with multiple comfort options players can choose from. Create the vignette and visual comfort system that reduces peripheral motion during movement. Define the frame rate and latency targets that are non-negotiable for comfort. Build the static reference point strategy for reducing vestibular conflict. Design the comfort settings menu allowing players to customize their experience.

3. Immersion & Presence Design
Design the scale and proportion system ensuring the virtual world feels physically correct. Create the environmental interaction system where players can touch, move, and break objects. Build the NPC interaction design for eye contact, personal space, and social presence. Define the audio spatialization approach that reinforces the sense of physical presence. Create the haptic feedback design language mapped to every interaction type. Design the body representation strategy whether full avatar, floating hands, or no body.

4. AR-Specific Design Considerations
Define the real-world integration strategy for placing virtual content in physical spaces. Create the surface detection and anchor system for stable AR content placement. Design the occlusion handling approach for virtual objects behind real furniture. Build the lighting estimation system matching virtual object shading to the real environment. Define the shared AR experience framework for multiple users in the same physical space. Create the passthrough and mixed reality transition design for hybrid VR-AR experiences.

5. Performance & Technical Constraints
Define the polygon budget, draw call limit, and shader complexity for the target hardware. Create the foveated rendering strategy for headsets with eye tracking. Design the level streaming approach for maintaining frame rate in large environments. Build the texture and asset quality strategy within the memory constraints. Define the audio processing budget for spatial sound on mobile VR hardware. Create the thermal management strategy for extended play sessions on standalone headsets.

6. Accessibility & Inclusive Design
Design seated play alternatives for every standing or room-scale mechanic. Create one-handed play options for players with limited mobility. Build the visual accessibility features including reticle customization, contrast options, and text scaling. Define the audio accessibility approach with visual sound indicators and subtitle systems. Create the motion sensitivity options beyond basic comfort settings. Design the physical fatigue management system to prevent repetitive strain injuries.
