“…(22) Several walking assistive devices for visually impaired people were developed by utilizing useful technologies such as various types of sensors, information fusion, RFID, and AI. (23) However, visually impaired people may not be able to buy devices because of their relatively low average income and the high price of the devices; the minimum price of walking assistive devices is currently roughly $500. To solve this problem, our new walking assistive device for visually impaired people has a simple structure and a light weight, and it should be possible to manufacture it at a low cost.…”

“…Details of the implementation of these four architectures can be seen in the main article previously published. (A new methodology applied to dynamic object detection and tracking systems for visually impaired people [1]). Fig.…”
This paper presents in detail the methodology for the detection and tracking of dynamic objects from the article in press (A new methodology applied to dynamic object detection and tracking systems for visually impaired people [1]). In order to validate this methodology, four different architectures have been designed in this paper. These architectures have implemented the techniques of pattern recognition, optical flow, background subtraction and color tracking to enable comparison and to see which is the most appropriate in a given environment. In this paper we also present a method created to quantify the effectiveness of each architecture implemented.
“…Unless the object comes in the perimeter of the cane it is not identified. A computerized system that recognizes objects without touching them and provides auditory feedback to the person giving more accurate understanding of the environment and avoiding threats involved in the overall process is needed [8][9][10][11][12]. Also the need of VI is not only to identify the obstacles but to gain a better understanding of the surroundings.…”
Human race is blessed with the five basic senses such as touch, taste, smell, hearing and the most important of them all 'vision or eyesight'. It is very difficult to survive without any one of them. Unfortunately a mass population across the globe suffers from the ill effects of vision, hampering their daily life. Detecting objects and providing navigational instructions in an indoor environment can considerably improve the day-to-day quality of life of visually impaired people. The motive of this research work is to propose a solution approach for assisting visually impaired population by identifying obstacles in front of them considering indoor environment. This approach focuses on feature extraction and object detection using Convolutional Neural Network (CNN) from a real time video. For this a head mounted image acquisition device may be used to detect the objects from the scene ahead and information of the detected objects is provided to the visually impaired (VI) person through the audio modality. As a first step towards the overall conceptual process, an object detection system is presented in this article, which processes the live video stream captured through the acquisition device. The video is processed frame-by-frame, treating each frame as a separate image and then using the proposed feature extraction and object detection algorithm to identify the objects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
