Vision disability is one of the most serious problems. Electronic travel aidsElectronic Travel Aid can help visually impairedVisually Impaired people to perform their mobility and navigationNavigation-related activities. This work presents an electronic travel aidElectronic Travel Aid that interprets the surrounding environment and conveys its audio representation to the user. It uses optical flowOptical Flow for tracking of obstacles. It computes the flow vectors of all the pixels in the frame by monitoring the current frame and the previous frame. The proposed solution implements dense optical flowOptical Flow which is based on Farneback’s algorithm. This aid is implemented in the form of smart clothing. The weight of this wearable and portable system is 440 g. This aid accurately detects the obstacle, its position, and the distance from the user. It shortlists the priority details of the surrounding environment and translate them into simplified audio feedback. It notifies these alerts via an earphone. This aid was subjected to ten usability experiments to assess its relevance as an electronic travel aidElectronic Travel Aid. It consistently helped the user to understand the surrounding environment and provided an average accuracy of 81.84% for overall obstacle detectionObstacle Detection.
