Smart Navigating Stick

The scope of this study is to create a product that will benefit persons who are blind or have to rely on others frequently. This is a unique concept that enables visually impaired persons to move around and go from one location to another with speed and confidence by identifying surrounding obstructions. They merely need to hold this device in their hands like a regular stick, and it will assist the individual in overcoming the impending challenges. Ultrasonic, Moisture, and Night sensors are among the sensors included. Designing an assistive system for visually impaired persons that can detect impediments and suggest alternate pathways for the blind are among the goals of this research project.

Patients with age-related visual loss suffer reduced ability to recognize faces and other scenes in photographs and on television. Recently, progress has been made in image enhancement, using controlled distortion of digitally stored images that increases their usefulness in particular applications. Described are two approaches to image enhancement for the visually impaired. In one approach, the visual losses that characterize individual patients and disease classes are described using detailed measurements of visual degradation transfer functions, which are profiles of loss of image information at various spatial scales. The particular distortion used for image enhancement is then adjusted to the impairment of the individual patient or disease class. A second approach takes advantage of the resemblance between the visual losses of many patients and the degradation of picture information in other applications due to external limitations (e.g., fog and haze) on photography. Several enhancement algorithms have been found useful with such images and may also improve picture recognition by the visually impaired.

The Individual ◽

The article tackles the problem of improving mathematical communication in a group of students with diﬀerent visual impairment levels, under the guidance of a group leader or a teacher. Visually impaired persons face a problem while learning mathematics. The said problem results from the speciﬁc nature in which mathematical content (formulas, function graphs, geometrical ﬁgures and projections of solids) is recorded and presented. The eﬀectiveness of learning mathematics is boosted when students work in a group moderated by a leader. This requires them to share documents, with the leader being able to keep track of the individual work of each participant, and with the group discussing speciﬁc solutions. In order for a visually impaired student to be able to participate in and contribute to the work of the group, either remotely or locally, all participants must use universal IT tools that support visually impaired students without complicating the work of others. This paper presents interactive multimedia solutions developed under two research projects carried out by the author. The said solutions support communication in mathematics. Results of qualitative surveys on new solutions are presented, conﬁrming their usefulness and the measurable impact they exert on the eﬃciency of the group’s work concerning mathematical problems.

Studies have shown inadequate reading materials for the visually impaired in Nigeria. Information technology has greatly advanced the provision of information to the visually impaired in other industrialized climes. This study investigated the extent of application of information technology to the transcription of reading materials for the visually impaired in Nigeria. The study adopted survey research design of the ex-post facto to select 470 personnel as respondents. A questionnaire titled Information Technology Use Scale (α=0.74), and Interview Schedule (α=0.75), were used. Data were analyzed using descriptive statistics and Pearson Product Moment Correlation. The findings indicate that information technology in transcription was low and a significant positive relationship between application of information technology and transcription of information materials (r=0.62: p<0.05). The study recommended among others that Multi-National Corporations should be sensitized to extend their Corporate Social Responsibility (CSR) activities to help in procuring modern information technology devices and software to enhance transcription.

Other authors have compared commercially available night vision aids used by visually impaired persons who have night blindness. The Wide Angle Mobility Lantern (WAML) is usually the more recommended device. This article suggests that other night vision aids, as yet unmentioned in the literature, may be equally effective and sometimes preferred to the WAML. Lights in the Streamlight series are comparable in price and size to the WAML and are more widely available. Personnel working with school-aged children who are night blind are encouraged to provide them with information about, and hands-on experience with, various night vision aids.

Many visually impaired individuals are found to be too passive or too aggressive in their social interactions. Lack of assertive behavior is related to the concept of learned helplessness. Components of assertive behavior are described with suggestions for enabling the visually impaired person to develop these skills. The underlying concepts of assertion training are explained along with specific techniques to be utilized in the school or rehabilitative setting. With a structured intervention resulting in improved assertiveness skills, blind or partially sighted individuals can increase their effectiveness in communicating with others and can feel more in control of their lives.
