An ultrasonic device is used for measuring the distance to a nearby object and SIFT algorithm based approach is used for object recognition from the captured image. Features of the recognized object as well as the distance to the object are converted to voice output which is available to the visually challenged person for navigation. The system developed and results obtained are described and suggestions are given for further work to be done to develop a better and more compact visual aid. 2017, Indian Academy of Sciences.Article
