Haptic Feedback | vendrux Docs

The Haptic Feedback feature provides tactile confirmation for user interactions through device vibration. This native function enhances user experience by delivering immediate physical feedback when actions are performed, creating a more engaging and responsive interface.

This guide helps you add satisfying vibration feedback to user actions in your Vendrux app, making interactions feel more responsive and engaging.

What is Haptic Feedback?

Haptic feedback refers to the use of touch sensations, particularly vibration, to communicate with users through their sense of touch. In mobile and touch-enabled applications, haptic feedback provides:

• Action confirmation: Immediate response that an action has been registered
• Enhanced user satisfaction: Tactile feedback creates a more engaging interaction
• Accessibility benefits: Additional sensory confirmation for users with visual impairments

When to Use Haptic Feedback

Haptic feedback is most effective in these scenarios:

• Button presses and tap interactions
• Form submissions and confirmations
• Toggle switches and checkboxes
• Swipe gestures and drag-and-drop actions
• Success confirmations (save, send, complete)
• Navigation transitions

Implementation

Basic Usage

The haptic feedback function is straightforward to implement:‍


if (navigator.userAgent.toLowerCase().includes('canvas')) {
    // Trigger haptic feedback
    nativeFunctions.hapticFeedback();
} else {
    // Web fallback - no haptic feedback available
    console.log('Haptic feedback not available in web environment');
}

Button Click Confirmation

function handleButtonClick() {
    // Perform the primary action
    submitForm();
    
    // Provide haptic confirmation
    if (navigator.userAgent.toLowerCase().includes('canvas')) {
        nativeFunctions.hapticFeedback();
    }
}

// Attach to button element
document.getElementById('submit-btn').addEventListener('click', handleButtonClick);

Best Practices

User Experience Guidelines

Timing and Responsiveness:

• Trigger haptic feedback immediately when the action occurs
• Don’t delay the feedback – users expect instant response
• Ensure the haptic feedback doesn’t interfere with the primary action

Consistency:

• Use haptic feedback consistently across similar interactions
• Establish clear patterns for when feedback occurs
• Document your haptic feedback strategy for team consistency
