AI-Powered Traffic Light and Object Detection for Visually Impaired People
Screenshot from the project

This mobile application prototype aims to help visually impaired people move more independently in urban environments. It detects traffic lights and surrounding objects from a live camera feed and communicates the results through spoken feedback.

Architecture

  • Android and Kotlin manage the camera feed, touch gestures and audio feedback.
  • TensorFlow Lite runs an SSD MobileNetV1 model for real-time object detection.
  • A CNN-based TFLite model classifies red and green traffic lights.
  • OpenCV supports image preprocessing.

Accessibility

The interface supports audio-led interaction and simple touch controls. On-device inference keeps processing local and reduces latency.

Technologies

Kotlin, Android, TensorFlow Lite, SSD MobileNetV1, CNN and OpenCV.
