Haptic Navigational Vest for Visually Impaired with LiDAR & Ultrasonic Obstacle Matrix
Wearable assistive vest with 4-zone directional haptic vibration motors and TF-Luna LiDAR rangefinder for intuitive hands-free indoor/outdoor navigation.
Project Overview
An ergonomic wearable prototype engineered with a central ESP32-S3 microcontroller, a TF-Luna micro-LiDAR distance sensor, 3 ultrasonic directional sensors, and an array of 4 ERM vibration motors mapped to directional proximity feedback. ### Real-World Problem Traditional white canes cannot detect upper-body, head-level, or fast-approaching overhead obstacles. ### Practical Student Solution Translates spatial distance telemetry into intuitive directional haptic pulses on the wearer's torso, enabling seamless navigation without holding equipment. ### Hardware Modules & Sensors - ESP32-S3 AI/BLE Board - TF-Luna Mini LiDAR - 3x HC-SR04 Ultrasonic Sensors - 4x ERM Haptic Drivers - Wearable Nylon Harness - LiPo Power Bank ### Commercial & Institutional Value Exceptional assistive tech demonstration prototype with strong hackathon and grant-winning track record.
Modern commercial and industrial infrastructure requires automated, real-time sensing and telemetry. Conventional manual monitoring suffers from high latency, human error, and lack of predictive fault visibility for Haptic Navigational Vest for Visually Impaired with LiDAR & Ultrasonic Obstacle Matrix.
A turnkey engineering prototype integrating high-precision sensor modules, dedicated microcontroller unit, and cloud telemetry protocols to automate measurement, trigger alert thresholds, and provide remote dashboard control.
