Visual Dignity Shield: A Cane With a Local Safety Layer
A Grade 11 student’s prototype adds obstacle sensing and on-device human-presence monitoring to a cane-style mobility device.
Field notes
The prototype mounts a Raspberry Pi 5, Camera Module 3, three ultrasonic sensors, and a buzzer onto a cane-style platform. Its two sensing layers cover approximately 180 degrees for obstacles and use a stated 10-second threshold for prolonged proximity; the page says processing happens locally, with no required cloud connection and no stored images. The documentation also records a community visit to Happy Home School for the Blind and links to a full research paper and project poster.
