Visual impairments often pose serious restrictions on a visually impaired person and there is a considerable number of persons, especially among aging population, which depend on assistive technology to sustain their quality of life. Development and testing of assistive technology for visually impaired requires gathering information and conducting studies on both healthy and visually impaired individuals in a controlled environment. We propose test setup for visually impaired persons by creating RFID based assistive environment – Visual Impairment Friendly RFID Room. The test setup can be used to evaluate RFID object localization and its use by visually impaired persons. To certain extent every impairment has individual characteristics as different individuals may better respond to different subsets of visual information. We use virtual reality prototype to both simulate visual impairment and map full visual information to the subset that visually impaired person can perceive. Time-domain color mapping real-time image processing is used to evaluate the virtual reality prototype targeting color vision deficiency.

Objective: to analyze mental health in the face of visual impairment, identifying the stages of psychological distress in the encounter with the not seeing. Method: This is an exploratory study with a qualitative approach. Fifteen adults with visual impairment attended at a specialized ophthalmology ambulatory in a university hospital in the city of Natal, Rio Grande do Norte, Brazil were studied, from June to August 2015, through a semistructured interview. The speeches were analyzed based on the theory of mourning. Results: the results showed that the mental health of the visually impaired person is structured through a normative apparatus constituted of individual and social attributes dynamically constructed. These attributes are related to the constitution of stages of mourning, characterized by shock, denial, bargaining, depression, and acceptance. The mental health of the visually impaired person contemplates the phases of normal mourning, established before the condition of visual loss, as structuring mode in a process of personal reconstruction, reflected in the ways of walking the life, proper from each one. Conclusion: With this study, it was possible to understand the ways of constitution and reconstitution of people in dealing with a new condition, the one of visual impairment, providing caregivers, family, and society with an ethical spirit and solidarity, more compliant and humane in the to deal with people with disabilities.

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.

□ Visual impairment is not necessarily blindness and the requirements of visually impaired persons are in many ways significantly different from those of blind persons. All too often agencies for the blind have not distinguished between these different requirements in providing services. The essential difference is that blind persons must rely on their other senses in order to function, while partially sighted persons must be helped to use whatever vision they have in coordination with their other senses. In providing services to partially sighted persons, the following basic principles should be considered: 1) Full service requires the cooperation of medical, physical, and behavioral specialists; 2) Services for partially sighted clients should be individualized on the basis of their differences in degree and quality of sight; 3) Whatever vision the client has should be augmented or strengthened through either mechanical or physical means; and 4) Clients should be helped to enhance their perception to its maximum functional potential.

This article thematizes relations between visual impairment and urban space, drawing from the analytical perspective of actor-network theory (ANT). It traces the ways in which visually impaired people create specific connections with space and how they transform it. Urban space is configured for use by able-bodied persons, for whom movement within it is easy and seems to be disembodied. However, for those who defy the standardization of space, the materiality of movement is constantly present and visible, because the passages are difficult to make and are not ready in advance. These materialities, as well as the strategies that people use to make connections with urban space, differ according to the assemblages that visually impaired people create. A route is different with a cane, a human companion, a guide dog, or the use of a combination of such assistance; the visually impaired person pays attention to different clues, follows specific lines, and other information is important and available. Each configuration makes it possible or impossible to do something; this shows disability as dynamic, and demonstrates the collective nature of action, which is more visible and palpable in the case of a disabled person.

This chapter shows how elements of gamification, i.e. game thinking and game mechanics, can be integrated into a collaborative navigation system for visually impaired persons in order encourage them to travel independently and thus improve their quality of life and self-confidence. The system supports independent navigation in unknown places by mediating help from another visually impaired person, who is familiar with the particular place. Our system utilizes a thermal user interface to introduce an additional communication channel and thus to increase the usability of the system. The system has been successfully enhanced by game elements and illustrates the potential of introducing game elements into these systems.

The California Psychological Inventory and the Minnesota Multiphasic Personality Inventory were administered to 128 women and men, aged 18-55, who were totally blind or partially sighted from birth, infancy, or early childhood, who had no other neurological, perceptual, or sensory-motor difficulties in addition to blindness, and had completed the eighth grade. The significant findings relate to the differences between the sample and sighted reference groups. Although both inventories seem to be highly sensitive to the adjustment patterns of early visually impaired persons, the findings clearly indicate that individual personality test results can be interpreted only when norms are appropriate and based on a representative group of visually impaired persons. Variant CPI and MMPI scale scores may not necessarily reflect psychopathology, but rather may be indicative of the unique adaptive processes of persons who experienced early visual impairment. Since the total experience of congenital or early visual impairment is not easily understood, normative data must be developed so meaningful and relevant comparisons can be made among persons who have shared common developmental experiences.

This article discusses two major obstacles that visually impaired persons face when considering the purchase of assistive technology—cost and lack of information about technology and financial assistance programs. The results of a survey of direct service organizations and three telephone surveys of visually impaired persons are presented to document the problem. Implications for administrators who wish to develop a financial assistance program are discussed.

This article presents a research program which examined the employment conditions of Swedish visually impaired persons, aged 25–45 at the onset of their visual impairment, who were employed at that time. A conceptual framework, through which the adaptive process necessary for the visually impaired individual to make, is addressed. The return to work did not necessarily mean that the person had been truly rehabilitated, since many of these workers were underemployed. Major qualitative changes of job characteristics also impacted dramatically on the workers.

Mobility for people with visual impairments is a challenge in placeswhere there is no knowledge of obstacles. Research carried out inthis work identified that people with visual impairment have difficultieswith obstacles located above 1 meter. Thus, an approach isproposed to notify the visually impaired person through sound andvibration about such obstacles. The proposed solution is available onthe ThingSpeak platform and components such as microcontrollers(ESP8266 NodeMcu ESP-12), sensors, buzzer and GPS were usedin its development. Results confirmed that the proposed approachcorrectly identified the existence of obstacles with a height equalto or greater than 1 (one) meter in the way of visually impairedpeople.
