Accessibility and UX
Practical frameworks for controller-based games that more people can play and enjoy.
Core Principle: Accessibility is Design
Accessibility isn't extra work—it's good design. Features that help disabled players often improve experience for everyone.
Controller Design
Button Mapping Principles
| Principle | Example |
|---|---|
| Primary actions on face buttons | Jump = A, Attack = X |
| Modifiers on shoulders | Sprint = L1, Aim = L2 |
| Menu on Start/Options | Pause, inventory |
| Movement on left stick | Always |
| Camera on right stick | When applicable |

D-Pad: Face:
Up: _______ Y: _______
Down: _____ A: _______
Left: _____ B: _______
Right: ____ X: _______
Left Stick: _______ Right Stick: _______

Remapping Checklist
- All buttons remappable
- Presets available (e.g., "lefty," "one-handed")
- Settings saved per profile
- Preview before confirming
Difficulty Options
Difficulty Spectrum
| Approach | Description | Accessibility |
|---|---|---|
| Single difficulty | One experience | Low |
| Presets | Easy/Normal/Hard | Medium |
| Granular options | Individual sliders | High |
| Assist modes | Specific helpers | Very High |
Granular Options Template
| Option | Range | Default |
|---|---|---|
| Damage taken | 50-200% | 100% |
| Damage dealt | 50-200% | 100% |
| Enemy aggression | Low-High | Normal |
| Timing windows | Generous-Strict | Normal |
| Auto-aim strength | Off-Strong | Light |
Assist Modes
| Assist | Helps With | Implementation |
|---|---|---|
| Invincibility | Can't die | No damage taken |
| Skip encounter | Stuck on fight | Button to bypass |
| Auto-complete QTE | Reaction time | Always succeeds |
| Increased coyote time | Precision | More forgiving jumps |
| Contrast mode | Visibility | High contrast colors |
Visual Accessibility
Colorblind Modes
| Type | Population | Solution |
|---|---|---|
| Protanopia (red) | ~1% male | Avoid red/green distinction |
| Deuteranopia (green) | ~6% male | Avoid red/green distinction |
| Tritanopia (blue) | ~0.01% | Avoid blue/yellow distinction |
Solutions
- Multiple colorblind presets
- Shapes/patterns in addition to colors
- Text labels on colored elements
- Customizable UI colors
Text Readability
| Element | Minimum | Recommended |
|---|---|---|
| Body text | 18pt | 24pt |
| Headers | 24pt | 32pt |
| HUD elements | 20pt | 28pt |
| Contrast ratio | 4.5:1 | 7:1 |
Audio Accessibility
Subtitles and Captions
| Feature | Description |
|---|---|
| Subtitles | Dialogue text |
| Closed captions | All audio described |
| Speaker names | Who is speaking |
| Direction indicators | Where sound comes from |
Audio Options
- Separate volume: Master, Music, SFX, Voice
- Mono audio option
- Visual cues for important sounds
- Haptic feedback for audio events
Motor Accessibility
One-Handed Play
- All actions possible with one hand
- OR alternative control scheme for one-handed
- No simultaneous button requirements
Reduced Input
- Hold instead of mash
- Auto-run option
- Simplified combo inputs
- Toggle vs hold options
Information Design
HUD Hierarchy
CRITICAL (always visible)
├── Health
├── Current objective
└── Immediate threats
IMPORTANT (visible when relevant)
├── Resources
├── Minimap
└── Active effects
OPTIONAL (toggle or menu)
├── Detailed stats
├── Quest log
└── Full map
Information Checklist
- Most important info most visible
- Redundant cues (audio + visual)
- Nothing purely color-dependent
- Font is readable at all sizes
- UI scales with resolution
Menu Design
Menu Navigation
| Best Practice | Reason |
|---|---|
| D-pad navigation | Precise, accessible |
| Clear current selection | Know where you are |
| Back button always works | Easy escape |
| Confirm = A/X | Convention |
| Cancel = B/Circle | Convention |
Settings Checklist
- Accessible from pause menu
- Changes apply immediately (or preview)
- Reset to defaults available
- Settings persist across sessions
Quick Accessibility Audit
