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.
