Smart Glasses & Blind Stick

Developed for JuFo 2021, this assistive technology suite bridges the gap between spatial awareness and digital connectivity. The system tightly integrates a virtual cane, dubbed the "iCane", which uses a single precise Ultrasonic sensor for environment mapping, with haptic-feedback Smart Glassesthat overlay directional cues onto the wearer's field of awareness.

Achieving sub-millisecond response times for obstacle detection required meticulous hardware-to-software integration. The core logic relies on a sophisticated dynamic tri-zone haptic and auditory feedback algorithm that instantly translates sensor distance into graduated physical and sound alerts. To ensure adaptability in the field, the firmware features a Serial CLI allowing for deep runtime calibration without requiring a reflash.

A custom Bluetooth Serial bridge maintains a persistent, low-latency connection between the wearable components. The bridge effortlessly multiplexes telemetry and state data between the iCane and the glasses, ensuring reliable delivery even in electromagnetically noisy environments.

For emergency features and remote monitoring, the system connects to an Android Companion App developed specifically for this project. The app handles GPS tracking and features direct WhatsApp SOS integration, instantly dispatching the user's live coordinates to emergency contacts with the press of a physical panic button.
