of obstacle detection . The Ultra Cane transmits the vibration feedback through two buttons, forcing the user to modify their grip . Present day systems available internationally cost more than 450 USD. WHO estimates show that there are 45 million blind people in the world of which 90% live in developing countries  where suc white cane is commonly used by blind people , which has two main disadvantages. It is relatively short and the detection occurs only by making contact with the obstacle which could sometimes might be dangerous. Another popular navigation tool for visually impaired individuals is a guide dog. Compare Any mobility aid for the visually impaired people should be able to accurately detect and warn about nearly obstacles. In this paper, we present a method for support system to detect obstacle in indoor environment based on Kinect sensor and 3D-image processing. Color-Depth data of the scene in front of the user is collected using the Kinect with the support of the standard framework for 3D. Obstacle detection is one of the major concerns for a fully or a partially blind person (e.g. person suffering from night-blindness, cataracts, glaucoma, albinism or injury). Presented here is a smart stick using Arduino Uno. The stick uses Ultrasonic sensors for obstacle detection
detection, and send information related to blind people. The system consists of microcontroller, ultrasonic sensor, and a vibratory circuit. This project aims at the development of an Electronic Travelling Aid (ETA) kit to help the blind people to find obstacle free path. This ETA is fixed to the shoe person mobility aid system works in a short range without the necessity of a full obstacle characterization. The main aim of this paper is to investigate the capability of a novel obstacle detection system designed for visually impaired and blind user mobility and based on the measurement of the TOF of an EM pulse transmitted from a wideband.
Almost 10% of all individuals who are legally blind also have a mobility impairment. The majority of these individuals are dependent on others for mobility. The Smart Power Assistance Module (SPAM) for manual wheelchairs is being developed to provide independent mobility for this population. A prototype of the SPAM has been developed using Yamaha JWII power assist hubs, sonar and infrared. Depth perception and obstacle detection glasses for the visually impaired using ultrasonic sensors and a binaural soundscape environment The urban environment is a very difficult place to navigate and orientate yourself through, especially if you are a visually impaired person trying to live your life A wireless rf based remote is used for this purpose.

(Bonus feature : Computer control using gestures) [Other details in comment] Project. Close. 375. Posted by 2 years ago For people who are deaf-blind The Miniguide is reliable for detecting obstacles (vibrations are sent as a warning when approaching an obstacle). It is often used to know if taking the right route. It identifies entrances or openings (indicated by the vibrations stopping when pointing at a wall), whi Y1 - 2020/3/12. N2 - Pedestrian lane and obstacle detection have been a big problem for a blind person. The person has to use special tool or assistant to do daily activities. This work has utilized camera function, connected with data processing (mini PC) to process information captured by a camera tool for blind persons. On the detection of obstacle in the path of the concerned person the smart blind stick sounds a buzzer to make an alert. With the proposed architecture, if constructed with at most accuracy, the blind people will able to move from one place to another without the help of others I am doing a project using ultrasonic sensors to detect the obstacle and its distance from the blind people and using microcontroller and headphones convey the related information to the blind people. Before starting with the hardware i would like to know if it is possible to do the same using Labv..

The process takes less than one minute and more than 90% of those who. small obstacle available on ground from the memory location and at the same time it will enable the first buzzer for informing the blind person about presence of obstacle on ground and thus avoidance the collision. C. Muddy Surface Detection Methodology Now, if the surface is wet or muddy it can cause slipping on the floor and thus can hurt  will help blind people to move in an unfamiliar environment. Keywords: Ultrasonic sensor, GPS, RFID, obstacle detection. detecting obstacle by listening instruction through audio I. INTRODUCTION Vision is the most important part of human physiology as 83% of information human being gets from the environment is via sight
The audio signal informs the user of the distance of the obstacle or the height of the drop off. This device can detect objects and hazards up to a distance of 12 feet. A part of the cane's handle also vibrates when there is an object in front of the user. The laser cane is suitable for persons who are blind and persons who are deaf blind Since the blind people are more efficient in hearing than the normal people, the system is focused on alerting the user through vibration and voice feedback about the surrounding obstacles. The System Architecture: The navigation system makes use of GPS, voice and ultrasonic sensors for obstacle detection Dalil ( Guide in Arabic) is a system that helps the blind to navigate in an unknown environment through object and obstacle detection. The solution consists of camera glasses linked to a smartphone application. The input is extracted directly from the glasses so the visually impaired person won't have to hold or carry any device with them or. The study aimed to create an obstacle detection device for blind people that would guide them especially with obstacles or obstructions in their proximity using audible warnings. The device was installed in a stick with four (4) ultrasonic sensors, a speech synthesizer and a microcontroller. The sensors were used to detect obstructions in the front, sides, and including head obstacles
the user. Therefore, the notiﬁcation method of obstacle distribution is as important as the obstacle detection method. The use of sensory substitution is an alternative way to transfer visual information of an obstacle and walking environment to the blind user.
