SmartCane - Tactile Pavement Substitution

Traditional mobility canes provide essential navigation support for visually impaired individuals, yet they rely heavily on environmental adaptations such as tactile pavements, which may not always be feasible indoors. The SmartCane project proposes an innovative alternative that enhances spatial perception using embedded color sensors and haptic feedback. By detecting colored tape on the ground, the SmartCane replicates the guidance provided by tactile pavements through distinct vibration patterns, allowing users to differentiate between safe paths, caution zones, and navigation cues without requiring permanent infrastructure modifications. The system is built around the Arduino Giga R1 WiFi microcontroller, integrated with TCS34725 color sensors, multiple vibration motors, and buzzers for auditory feedback. The microcontroller processes sensor data and triggers real-time haptic and auditory feedback to inform users of their surroundings. To further enhance indoor navigation, the SmartCane employs Bluetooth beacons that communicate with a companion mobile application. These beacons, strategically placed at key locations such as entrances and path intersections, provide additional directional assistance and safety warnings. The mobile app interprets beacon signals to offer real-time auditory cues, such as distance from intersections or notifications upon entering a beacon-equipped building, supplementing the cane’s tactile feedback. The project follows a structured development timeline, beginning with hardware and sensor selection, followed by software implementation for color detection and vibration feedback. Subsequent phases include field testing, refining sensor accuracy, and integrating Bluetooth communication. User testing with visually impaired individuals will provide insights for further improvements in usability and reliability. Designed for portability and adaptability, the SmartCane offers a cost-effective and scalable assistive solution that complements existing accessibility tools. By leveraging embedded systems, wireless communication, and user-centered design, this project aims to enhance independence and mobility for visually impaired individuals, particularly in indoor environments where traditional tactile pavements may be impractical.
