Digital Radar Aided Cane

Abstract

The life of the blind people is very hard, even today in the 21. Century, when there are several things that make their life easier. Their biggest problem is traffic, because people sense the environment mostly through their eyes and sadly, the other organs cannot substitute sight. On the other hand, in traffic one risks the lives of others too. Serious injuries can be obtained by not seeing the obstacles in the homes. Bones can break, or even worse, permanent injuries can occur. In serious cases even the chance of death is present. Our vision is to help in this problem by developing a device and corresponding software. Handling should be easy, dynamic and minimalistic. The solution consists of two parts. The first being the software running on a Windows Phone based mobile phone, and the other one is the custom built DRAC1 hardware. The hardware contains an ultrasound sensor and two infrared sensors which detect the distance between the objects and the phone, and then the software processes the signal and notifies the user.
