An Al Edge Computing Based Wearable Assistive Device for Visually Impaired People Zebra-Crossing Walking

This paper proposes an artificial intelligence (Al) edge computing-based wearable assistive device for assisting zebra-crossing walking of the visually impaired people. The proposed assistive device is composed of a pair of smart glasses, a walking cane, and a waist-mounted box. When the visually impaired pedestrian prepares to cross the zebra-crossing, thus the visually impaired pedestrian will receive the current traffic light signal message. The visually impaired guidance voice service will be provided via Bluetooth (BT). Moreover, when the walking offset occurs on the zebra-crossing, then the visually impaired pedestrian will be reminded through the voice prompt of the earphone.
