Sounds & Haptics

Ferni communicates through multiple senses. Audio and haptic feedback should feel organic, warm, and intentional—never clinical or mechanical.

Philosophy

Sound

Every sound should feel like it belongs in nature—warm chimes, soft tones, organic textures. Never harsh, never robotic.

Haptics

Touch feedback that feels like communication—breathing rhythms, heartbeats, gentle acknowledgments. Felt, not noticed.

Timing

Synchronize with user actions. Immediate for confirmations, gentle delays for emotional moments. Never jarring.

Sound Library

All sounds are designed to feel warm and organic. Each category serves a specific emotional purpose.

Accessibility

Sensory feedback must respect user preferences and never be the only feedback channel.

System Preferences

  • Always check isReduceMotionEnabled
  • Always check isHapticsEnabled
  • Reduce intensity 50% in low power mode

Fallbacks

  • Haptics disabled → Visual + audio feedback only
  • Audio disabled → Visual + haptic feedback
  • Always provide visual confirmation

Principles

  • Never make haptics the only feedback
  • Always pair with visual or audio
  • Provide option to disable all haptics
  • Test on real devices, not simulators

Implementation

iOS (Swift)

// Ferni Breath Pattern
let generator = UIImpactFeedbackGenerator(style: .medium)
generator.prepare()

func playFerniBreath() {
    let pattern: [Double] = [0.2, 0.4, 0.6, 0.8, 1.0, 0.8, 0.6, 0.4, 0.2, 0]
    for (index, intensity) in pattern.enumerated() {
        DispatchQueue.main.asyncAfter(deadline: .now() + Double(index) * 0.03) {
            generator.impactOccurred(intensity: CGFloat(intensity))
        }
    }
}

Android (Kotlin)

// Ferni Breath Pattern
fun playFerniBreath(vibrator: Vibrator) {
    val timings = longArrayOf(0, 30, 30, 30, 30, 30, 30, 30, 30, 30)
    val amplitudes = intArrayOf(0, 51, 102, 153, 204, 255, 204, 153, 102, 51)
    val effect = VibrationEffect.createWaveform(timings, amplitudes, -1)
    vibrator.vibrate(effect)
}

Web (Limited Support)

// Web haptics have limited support
// Use visual pulse as fallback
function playFerniBreath() {
    if ('vibrate' in navigator) {
        navigator.vibrate([30, 30, 30, 30, 30, 30, 30, 30, 30, 30]);
    }
    // Always show visual feedback
    element.classList.add('pulse-animation');
