The samples from the trial application functionality. It found that the app offers a hypersensitivity response. Because when the touch screen once it goes into operation in the next step immediately. In fact, Blind people have a habit of touching things like petting. It falls to the touch screen, with no need to push it back to the original page is open, which is quite time consuming. If it turns out to touch the screen once a second time to make applications easier. But overall I was pleased with the application and would like to develop further both the ringer and notification sounds good because it makes us feel, and prepare in time. But he has repeatedly notified when a bus is approaching more vibration and noise while the notification period is too short. And my vibrations with frequencies greater than this. Because most people are blind to the neck strap. The other hand was holding a cane. It also requires a sense of the rest of the fumble. It makes you feel a vibration alert is slow. And urge the frequency of the oscillation period lasting more than this.
