Smart cane location guide for blind using GPS

Visually impaired have a deficiency in their vision which has limitations in terms of mobility. On the other side, the blind must also run their daily activities. Sometimes, the blind must performs a mobility from one building to another building in some area which has a distance like campus, mall and others. In order to make the visually impaired mobility becomes easier, we created a tool that can help them to detect the location of the destination buildings or inform them where the position of the standing place through the sound as the output information. Prototype made using the GPS module, keypad, earphone and raspberry Pi. The results show that the functional testing tools can detect the location area of interest with a deviation of less than 8 m. Also based on the friendly user testing, this prototype categorized good enough to be used by the blind.
