Vision Assistance App

Overview

The Vision Assistance App is designed to empower individuals who are completely or heavily partially blind by helping them navigate the real world independently. Leveraging AI-powered object detection, haptic feedback, and emergency features, the app enhances accessibility and safety.

✨ Key Features

🔍 Object Detection & Distance Feedback

Uses the mobile device’s camera to detect objects in real-time.
Divides the field of view into a 9-quadrant grid (3x3) for precise object localization.
Estimates object distance and provides intensity-based haptic feedback.
Recognizes common household items and human faces accurately.

🎛 Interactive Controls

On-Screen Buttons:
- Describe Object in Detail: Short description on tap, detailed info on long press.
- Call Emergency Contact: Quick dial to a preset contact (family, caretaker, etc.).
- Customizable Buttons:
  - Voice commands 🎙
  - Saving object details for later reference 📝
  - Adjusting vibration intensity ⚙
  - Toggling features on/off 📴
- Physical Button Shortcuts: Volume and power button combinations for quick actions.

🚨 Emergency Features
