BatNAV is a wearable shoe-mounted device that replaces the white cane. It includes: Ultrasonic sensors to detect obstacles in the path Vibration motors that alert the user with varying intensity based on distance Arduino Nano + Gyroscope for processing and orientation Custom-designed PCB Elastic straps for easy shoe mounting The vibrations notify the user about the proximity of objects in real-time, offering safe and dignified navigation. The logo of a bat was used to make the product feel like a stylish accessory rather than a medical aid. 

Idea: Inspired by their friend Moksh, who has 100% visual impairment and feels uncomfortable using a white cane in public, the team aimed to build a discreet and empowering alternative. The solution had to be user-friendly, subtle, and wearable. Constraints: Must be inconspicuous Lightweight and portable Usable independently by the visually impaired Must be accurate to avoid misdirection or risk
