Abstract The GuideWay system is a smart wearable designed to support visually impaired people in their everyday movements, especially in unfamiliar or crowded places. It uses a Raspberry Pi as the main controller, connected to ultrasonic sensors, a camera, and GPS so that it can sense obstacles and understand the user’s surroundings in real time. With AI-based object recognition, GuideWay can recognize different obstacles, estimate how far they are, and then warn the user using clear audio messages and vibration patterns, helping them move safely both indoors and outdoors. Beyond navigation, GuideWay also cares about emergencies and daily routines. If the user falls or is in trouble, the device can automatically send their location to a caregiver through an emergency alert feature. It can also give spoken reminders, for example for taking medicines on time, which supports independent living. By bringing together embedded hardware, computer vision, and artificial intelligence in a compact wearable form, GuideWay aims to be affordable, reliable, and easy to use, ultimately improving the mobility, safety, and quality of life of visually impaired individuals.
