Providing Touch Feedback

1. Introduction

Touch feedback is an essential aspect of mobile-first design, providing users with visual or tactile responses when interacting with touch elements. This lesson covers how to implement effective touch feedback to enhance user experience.

2. Key Concepts

3. Step-by-Step Process

3.1 Implementing Visual Feedback

Visual feedback can be implemented using CSS transitions and animations.

.button {
    background-color: #007bff;
    transition: background-color 0.3s, transform 0.1s;
}

.button:active {
    background-color: #0056b3;
    transform: scale(0.95);
}
        

3.2 Adding Haptic Feedback (for supported devices)

For mobile devices supporting haptic feedback, use the Vibration API.

function triggerHapticFeedback() {
    if (navigator.vibrate) {
        navigator.vibrate(100); // Vibrate for 100 milliseconds
    }
}
        

4. Best Practices

• Provide immediate feedback for touch interactions.
• Use color contrast to indicate active states.
• Limit haptic feedback to avoid overwhelming the user.
• Test touch feedback across various devices for consistency.
