Description of Invention
Blind people still face challenges in navigation when they use the conventional white cane because it cannot detect the head-level and trunk-level obstacles. Hence, our group proposes a smart mobility aid for blind people called 'Smart Walking Cane (SWC)'. It is built on an ESP32 with RTOS implementation. Two ultrasonic sensors and one human sensor are used to detect the head-level obstacles, trunk-level obstacles, and the presence of human. Vibration and sound are the alert notification. Mobile phone is connected to SWC for cane's setting and location tracking purposes. The SWC has great potential in commercialization because it helps the blind people.
