Execution Flow

INTERACTION DESIGN EXECUTION
────────────────────────────────────────────

Step 1: UNDERSTAND USER GOALS
├── Identify user intent
├── Map expected outcomes
└── Define success criteria

Step 2: DESIGN TRIGGERS
├── Define interaction triggers
├── Specify input methods
└── Consider accessibility

Step 3: CREATE RESPONSE
├── Design visual feedback
├── Specify timing/easing
└── Add audio/haptic (optional)

Step 4: HANDLE STATES
├── Success state
├── Error state
├── Loading state
└── Empty state

Step 5: DOCUMENT & TEST
├── Create specifications
├── Prototype interactions
└── Validate with users

────────────────────────────────────────────

Retry Logic

retry_config:
  max_attempts: 3
  backoff_type: exponential
  initial_delay_ms: 500
  max_delay_ms: 5000
  retryable_errors:
    - ANIMATION_RENDER_FAILED
    - PROTOTYPE_SYNC_ERROR

Logging Hooks

interface InteractionLog {
  timestamp: string;
  event: "interaction_start" | "feedback_shown" | "complete" | "error";
  interaction_type: string;
  duration_ms: number;
  success: boolean;
}

Learning Modules

Module 1: Interaction Patterns

COMMON PATTERNS
├── Navigation
│   ├── Tab navigation
│   ├── Sidebar toggle
│   └── Breadcrumbs

│   ├── Infinite scroll
│   ├── Pull to refresh
│   └── Expand/collapse
└── Actions
    ├── Drag and drop
    ├── Swipe actions
    └── Long press

Module 2: Micro-interactions

MICRO-INTERACTION ANATOMY
├── Trigger (user action)
├── Rules (what happens)
├── Feedback (visual response)
└── Loops/Modes (ongoing state)

TIMING GUIDELINES
├── Instant: 0-100ms (feedback)
├── Fast: 100-300ms (transitions)
├── Normal: 300-500ms (animations)
└── Slow: 500ms+ (complex sequences)

EASING CURVES
├── ease-out: Deceleration (entering)
├── ease-in: Acceleration (exiting)
├── ease-in-out: Smooth (moving)
└── spring: Natural (bouncy)

Module 3: User Flows

FLOW DESIGN PRINCIPLES
├── Minimize steps to goal
├── Provide clear progress
├── Allow easy recovery
├── Confirm destructive actions
└── Remember user state

FLOW COMPONENTS
├── Entry points
├── Decision points
├── Action points
├── Exit points
└── Error paths

Module 4: Affordances

AFFORDANCE TYPES
├── Explicit (buttons, links)
├── Pattern-based (icons, gestures)
├── Hidden (shortcuts, gestures)
└── Negative (disabled states)

SIGNIFIERS
├── Visual cues (icons, arrows)
├── Text labels
├── Cursor changes
├── Animation hints
└── Sound cues

Module 5: Feedback Systems

FEEDBACK TYPES
├── Visual (color, motion)
├── Auditory (sounds, voice)
├── Haptic (vibration)
└── Systemic (notifications)

FEEDBACK TIMING
├── Immediate: < 100ms
├── Responsive: 100-300ms
├── Perceived: 300-1000ms
└── Delayed: > 1000ms (show progress)

Error Handling

Troubleshooting

Problem: Users miss interactions

Diagnosis:
├── Check: Affordance visibility
├── Check: Position in hierarchy
├── Check: Size and contrast
└── Solution: Enhance discoverability

Steps:
1. Conduct findability test
2. Increase visual prominence
3. Add onboarding hints
4. Consider progressive disclosure

Problem: Interactions feel slow

Diagnosis:
├── Check: Animation duration
├── Check: Easing curves
├── Check: Response delay
└── Solution: Optimize timing

Steps:
1. Measure time to feedback
2. Reduce to 100-300ms range
3. Use appropriate easing
4. Add immediate micro-feedback
