Smart Cane: Public Transportation Code Detection and Identification System for Visually Impaired

The visually impaired people are still having difficulties to be able to take advantage of public transportation in their daily activities. The lack of the facilities that provide convenience and comfort to use public transportation, makes a limitation of the movement of the visually impaired people. This research built an extend system for the blind cane which can determine the existence of the public transportation near the visually impaired. This system is constructed using [Arduino Uno, numeric button, buzzers, white cane and the Radio Frequency APC 220. This system consists of smart cane module and public transportation module. The testing was conducted to determine the RF module range between the smart cane and the detection Public Transportation vehicle with various scenarios. The result stated that public transportation can provide information on arrivals to the visually impaired people with a range of distances of 80-100 meters, depending on the air regulation. The system runs about 31-32 seconds to detect and identify the public transportation.
