The sense of vision is essential in life. Blind persons have difficulties navigating both indoors and outdoors. A cane is a very important tool for them. However, using conventional cane is quite hazardous and time-consuming. To navigate safely and successfully, they need a device that is more than just an ordinary cane. In this study, an electronic guidance system that is equipped with both Global Systems for Mobile (GSM) and Global Positioning System (GPS) features had been designed and evaluated. The system is capable of alerting the user of the presence of nearby obstacles along the navigation path. It can give audio signals containing the GPS coordinates and direction details of the user. Through the GSM module, the system can send a message containing the location details of the blind user to a dedicated receiver in cases of emergencies. Experiment results had shown that the designed system can effectively detect obstacles and can efficiently provide the location and direction details. With this system, the travel time of the blind user had been significantly reduced by 21.26 percent.
