Smart guide extension for blind cane

Cane is a tool that used by blind people or someone who has visually impaired which is caused by an accident or an illness. Cane helps the blind people to check whether there are any obstacles around them. However, before doing the research, we conducted a questionnaire to the blind people about what kind of extension module that would be implemented on their cane. Based-on the result, they need an extension smart tools for their cane that can give information about hitch, obstacle, hole, and also the direction of compass wind position to guide their way and also inform them Qibla direction. This research designed a prototype named Smart Guide Extension that can detect obstacles, holes and give information about eights wind direction using Arduino. The obstacles and holes module uses 2 PING Sensors, while the 8 direction of the wind information uses CMP compass sensor 511. All the information will be informed through the sound. The results of testing the obstacle data module stated that the buzzer will be active at a distance of 150 cm-3 cm and the speed of beep sound faster from 1.1 until 0.3 seconds. The test holes modules state that the beep sound active at a distance of 10-50 cm. The system can detect eight direction of the compass wind position with deviation angle position about ±3°. Based on the questionnaire of trial prototype to the responder, 77.38% of responder stated these tools are user friendly and easily to used.
