AIDING VISUALLY CHALLENGED INDIVIDUAL FOR OBJECT DETECTION AND NAVIGATION USING ASSISTIVE TECHNOLOGY

D. Priyadharshini, M. Dhivya

Abstract: Visual impairers are not a new augury for the society. It is a condition of deficient visual perception. Accessibility in the anonymous environment for the visually challenged individuals is more critical. They are more prone to fall in accidents since they cannot discern their surroundings. The wide availability of equipment’s which help the blind people are quite expensive and cannot be easily expanded. Moreover the most of the techniques prevailing to aid them with the help of IR sensors do have a drawback i.e. in the presence of the sunlight it won’t produce an efficient result. For overcoming these drawbacks, the current paper contributes two concepts. The First concept deals with the identification of hindrance such as trees trunk, opened doors, stair case, etc. This is done with the help of an Obstacle Detection Unit (ODU) which discovers the obstacle that are against the visually impaired by capturing the image of the object present. In the latter case, Navigation Tracking Device (NTD) delivers route for the impaired where they wish to proceed without any human assistance.
