File contents

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.
