Abstract

We implement a wireless pedestrian navigation system for the visually impaired. The system consists of a smartphone with a voice recognition function, a budget direction guide and an osteoacusis headset, which can provide auditory guidance directions while recognizing the sound of the surrounding environment. Experimental results show that the average directional angle error is 8.56 degrees (standard deviation: 14.78), average difference between GPS path and scheduled path is 5.55m (standard deviation: 3.79) and maximum difference is 13.22m in the experimental path, based on which can be stated that the user was navigated relatively stable by the developed system.
