Obstacle detection device for physically challenged people

In last few decades there has been a rapid increase in research work in the field of wearable devices for the physically challenged people. However the research work being carried out is still in the preliminary stage and the wearable devices are just coming into existence and beginning to display some future potential. Hence there are not many wearable devices available which can substantially benefit the physically challenged person in improving the lifestyle. In this study we have attempted to propose a design of a wearable travelling aid for a person who is blind as well as deaf. The wearable is an electronic device in which Infrared sensors (IR) are deployed to detect obstacles which are in close proximity to the user. Furthermore, on detecting the obstacle, the wearable device warns the user with the help of haptic sensor. The wearable device is hands-free and easy to operate and with the use of the IR sensor it is easy to detect the obstacle as it is a sharp detector and also covers the significant range of distance.
