Abstract
The smart glasses present a real-time obstacle detection and tactile feedback system utilizing an Arducam Time-of-Flight (ToF) depth camera integrated with vibration motors. The system is designed to enhance spatial awareness by detecting obstacles within predefined regions of interest (ROIs) and providing corresponding tactile alerts.
Key Features
- Depth data processing to identify minimum distance of objects within left, middle, and right ROIs
- Vibration motors actuated with varying frequencies based on object proximity
- Closer obstacles trigger higher vibration frequencies for intuitive feedback
- Optimized sensor performance through depth noise filtering
Technical Implementation
- Hardware: Raspberry Pi, Arducam ToF Camera, Vibration Motors
- Software: Python, OpenCV
- Fabrication: 3D Printed enclosure
Technical Skills
Raspberry Pi, Python, 3D Printing, ToF Camera, Signal Processing
