The visually impaired are the people who can have permanent or temporary loss of vision. Such people cannot see, read or write as the normal human beings. There are several substituting equipments and aid to help them lead a normal life. Similarly to read, Braille notations are being used. These Braille editions are not available for each text book. Thus to help them read the conventional text ...

Different text to Braille converter software for different languages is currently available. But for Sinhala language there is no such converter. Hence the visually impaired people of Srilanka who work with Sinhala language, suffer a lot. They need to operate manually for getting the desired output, which is a time consuming procedure. This software / conversion engine will easily convert the S...

Limited sensory information about a new environment often requires people with a visual impairment to rely on sighted guides for showing or describing routes around the environment. However, route descriptions provided by other blind independent navigators, (e.g., over a cell phone), can also be used to guide a traveler along a previously unknown route. A visually impaired guide can often descr...

Wayfinding is of vital importance if visually impaired pedestrians are to walk by themselves from one place to another, since they must calculate both their orientation and position. Here, a new haptic direction indicator is proposed, which will help blind pedestrians to avoid hazardous areas intuitively and safely by means of haptic navigation. A novel translational force perception method, ca...

Navigation in indoor environments is highly challenging for the severely visually impaired, particularly in spaces visited for the first time. Several solutions have been proposed to deal with this challenge. Although some of them have shown to be useful in real scenarios, they involve an important deployment effort or use artifacts that are not natural for blind users. This paper presents an i...

Many of the current GPS (Global Positioning Systems) navigation aids use an audio method to deliver navigation information to the user. For the visually impaired person this method can be problematic. The visually impaired pedestrian relies heavily on information contained within the ambient sound environment; for location and orientation information, navigation information, and importantly, sa...

-This paper suggests a smart blind stick that detects obstacle in front of man on street. Arduino and ultrasonic sensor is used to detect the depth below or obstacles between LED, Buzzer,9V Battery, Jumper wires, stick. As per statistics World Health Organisation (WHO), currently there are 45 million people all around globe. The visually impaired very much dependent external assistance such as ...

The aim of this paper is to represent a method where a blind person can get information about the shape of an object through speech sound. Nowadays a lot of image shape approximation and representation algorithms are available, but these representations are very lengthy. Here, we have proposed a digital image shape approximation method where a shape boundary is divided & approximated to a few n...

Door is a very significant element as it enables person to enter house or room. Though identifying doorway an easy task for regular person, robots visually impaired people challenging task. To overcome this challenge, we have proposed door detection method. Our method based on Prewitt edge and Harris corner detector. Here, are using number of predefined rules detect the doorframe correctly. est...
