Abstract

krooree.comEcho Guidance is an innovative assistive technology designed to enhance mobility and independence for visually impaired individuals. Using ultrasonic sensors, it mimics bat-like echolocation by emitting sound waves and measuring the time it takes for them to bounce back, accurately detecting nearby obstacles. The system provides real-time feedback through vibrations or voice alerts, offering navigation cues such as “Turn left in 10 steps” or “Obstacle ahead, 3 meters.” It operates effectively both indoors and outdoors, combining GPS for open-space navigation with precise sensors for complex environments like malls or busy streets. Over time, Echo Guidance learns and adapts to the user’s surroundings, improving its guidance with continued use. Whether worn as a wristband, integrated into a cane, or used via a smart device, it serves as a personal navigation assistant, helping users move confidently and safely. By replacing visual inpu
