We are developing the robot in order to guide visually impaired persons in large hospitals. This paper describes the structure of the robot and the results of a demonstration examination in Kanagawa Rehabilitation Hospital, Japan. The robot navigates to the destination while steering, depending on the force with which the user pushes on the robot. The success rate for reaching a destination with the robot was higher than with a white cane in the testing at Kanagawa Rehabilitation Hospital. We evaluated the traveling time and the participant questionnaire as an endpoint by Wilcoxon signed-rank test. Though there is no advantage in traveling time between use of the white cane and the robot, according to the scores of the participants questionnaire, it was shown that traveling with the robot was better than traveling with the white cane for the participants.

Although fax communications pose a problem of accessibility for blind and visually impaired office workers, with centralized readers’ services they could be used to address the wider reading needs of blind and visually impaired people. With this technology, blind persons with fax machines could send unknown print to readers at a centralized readers’ service, who would read facsimiles of the documents over voice phones. This article discusses the specifications for appropriate equipment and protocols and presents the preliminary results of a study of such a system.

This article reports on a national survey of recreation personnel in agencies and schools for blind and visually impaired persons. The survey addressed the personnel's employment status, educational background and continuing education experiences, professional affiliation, and interest in networking with other recreation personnel who work with blind and visually impaired persons.

Objective of this study is to help the basic standing position training to take its part among basic exercises of the visually impaired individuals, and to observe the effects of this training on walking and balance skills.Method: 8 visually impaired sedentary individuals with impairment levels of B1 and B2 and ages of 18 to 24 voluntarily participated in the study. After acknowledging the visually impaired individuals with audial information regarding the study, they were told to brisk walk for 15 steps against the audio signal and then to heel-to-toe walk for 15 steps. Their corresponding walking distances, walking durations, directional impairments and losses of balance were recorded. During the 8 week period following this test, 45 minute training sessions accompanied by trainers that included 4 basic standing positions and their combinations were applied once a week, where the trainer corrected the individuals verbally and physically. Abovementioned tests were repeated after these 8 weeks. Gender categorization was not made since the participants were few in number. Non-parametric Wilcoxon Signed Rank Test was applied and a significant increase for the pretest was observed at a 0.05 significance level, where the distances walked increased and walking durations along with losses of balance decreased.Result: It was observed that walking skills of visually impaired individuals that received verbal and physical assistance, and that effectively performed basic positions and their combinations were smoother and more confident; that their walking distances were increased, their losses of balance were decreased and that they encountered less deviations from the direction of movement while walking, compared to their pretest conditions. Starting from this point of view, it might be concluded that the basic standing positions were highly beneficial and applicable activities for walking training of visually impaired individuals.

The White Cane – A tool that both helps and hinders Bodies, shame, normality and the agency of objects   Maria Bäckman   The article discusses the attempts of visually impaired individuals tosometimes pass as seeing. The background is the resistance that many blind or visually impaired people testify they feel, during their ongoingrehabilitation, about a white cane. Often, on these occasions they provid descriptions of dramatic narratives in which the user explains what it was like when they first realized that it was now really time to start using a cane (for example: When I fell in the water from the quay, or stepped out in front of a bus, etc.). However, many also relate the way a cane, even in more mundane contexts, makes the individual’s visual inability obvious to others and thereby makes the person particularly vulnerable. The tool that connects the visually impaired with the outside world is thus also a material expression which makes both the visual damage and the cane usersmore noticeable as less than a fully functional individual.By holding on to the materiality of the cane and its nature of being a physical object, our understanding can be increased of the ambivalent relationship that many visually impaired people develop with a white cane. On the basis of social materiality studies and the concept of ableism, taken from critical handicap research, the article shows how the use of a white cane takes place in a public space; a space where the user variously inhabits an “imaginary” full-sighted body and another, existing body, which on the contrary is characterized by its weakened vision. However, it is important to realize that the persistent rejection mechanism that many visually impaired people have for a cane is intimately linked to ableism and existing norms of bodily functions. A desire to repel an object that reduces one to something else, and consequently to a somewhat lower standing, is a perfectly reasonable reaction to a deeply rooted social conflict. For many people with visual impairment, the resistance to a white cane must therefore be understood as a refusal to embody a functional normative failure.

The aim of this study was to determine the level of social distance towards visually impaired people in relation to the occupation of respondents. The study included 361 adult respondents from the territory of Bosnia and Herzegovina, and who had no personal, not professional contact with persons with impaired vision. For the purpose of this study was used scale of social distance (Oullette-Kuntz, Burge, Brown, Arsenault, 2010), which is adapted in terms of required statements and opinions of respondents to visually impaired people, rather than toward people with intellectual disabilities. For statistical analyzes were used methods of descriptive statistics, and methods of analysis of variance (ANOVA). All results of the study were conducted at a significance level of 0.05. The results indicate that there is no statistically significant difference in the opinions and level of social distance in relation to the occupation of respondents.

A caseload size survey was conducted of both public and large private agencies serving blind and visually impaired people. Wide variations in caseload size were found between different types of professional caseworkers, between agencies, and between public and private agencies.

We developed a robot that can guide visually impaired people and elderly people as they walk around in large hospitals. In relation to this, a previous report described the structure of a guidance robot and the comparison of its use with that of a white cane. It was shown that with the use of the robot, participants could move more easily, safely, and confidently than with a white cane. However, to solve the problems encountered with the use of the previous robot, a new guidance robot was fabricated. This paper describes the structure of the new robot and the results of the demonstration examination of the robot in the Kanagawa Rehabilitation Center. The robot navigates to reach a destination set by using the touch panel, whereas velocity depends on the force exerted by the user on the robot. The questionnaire answered by the participants were evaluated using the system usability scale, which showed that the acceptability range of the robot is “Acceptable” and its usability is high.

Public attitudes toward blindness are shaped by limited contacts with visually impaired people and unrealistic portrayals of blind people in the media. These attitudes hamper the integration of blind and visually impaired persons in society. Professionals in the field need ‘to work together to develop national and local public education programs to change stereotyped thinking. Proactive efforts that include a variety of methods can begin to humanize blindness and hence can lead to greater opportunities for fuller participation in society.
