Geometric Fuzzy Techniques for Guidance of Visually Impaired People

In this paper we present the design of a device to guide the visually impaired person who normally uses a cane. We propose a non-invasive device that will help blind and visually impaired people to navigate. The system uses stereoscopic vision, a RGB-D sensor and an IMU to process images and to compute the distances from obstacles relative to cameras and to search for free walking paths in the scene. This computing is done using stereo vision, vanishing points, and fuzzy rules. Vanishing points are used to obtain a main orientation in structured spaces. Since the guidance system is related to a spatial reference system, the vanishing point is used like a virtual compass that helps the blind to orient him- or herself towards a goal. Reinforced with fuzzy decision rules, the system supports the blind in avoiding obstacles, thus the blind person is able to cross structured spaces and avoid obstacles without the need for a cane.

Impaired Person

This paper proposes an effective device for visually impaired person in order to have betterment in their routine life. The spread of visually impairment is very sensitive issue worldwide. Here we develop a Smart system for visually impaired, that make use of ultrasonic sensor and camera.The most point of this work is to plan a voice-based cautioning framework for the outwardly impeded individuals. Visually impaired individual’s finds navigation difficult as they struggle every day in performing actions for bypassing obstacles and hurdles in their regular life. In order to help visually impaired people navigate safely and quickly this system is proposed. Ultrasonic sensor is set on the exhibition which is utilized for impediment location with separate sign. The camera is set to detect the object before the outwardly impeded individuals and alarm them utilizing APR voice module. This system prevents the visually impaired people accidents and identifies the object in front of them. The scope of the work is extracting the object’s image and processing them in the knowledge base and interpret the captured one. Assistive Innovation for individuals with outwardly disabilities is anticipated to develop at a quick pace and affect the lives of people having visual impedance and the elderly ways previously is not possible.

Visual Light

Blindness is a state of lacking the visual perception due to physiological or neurological factors. The partial blindness represents the lack of integration in the growth of the optic nerve or visual centre of the eye, and total blindness is the full absence of the visual light perception. In this work, a simple, cheap, friendly user, smart blind guidance system is designed and implemented to improve the mobility of both blind and visually impaired people in a specific area. The proposed work includes a wearable equipment consists of head hat and mini hand stick to help the blind person to navigate alone safely and to avoid any obstacles that may be encountered, whether fixed or mobile, to prevent any possible accident. The main component of this system is the infrared sensor which is used to scan a predetermined area around blind by emitting-reflecting waves. The reflected signals received from the barrier objects are used as inputs to PIC microcontroller. The microcontroller is then used to determine the direction and distance of the objects around the blind. It also controls the peripheral components that alert the user about obstacle's shape, material, and direction. The implemented system is cheap, fast, and easy to use and an innovative affordable solution to blind and visually impaired people in third world countries.
