The information-seeking process of blind and visually impaired Grade 12 learners in selected South African schools for the blind

All people seek information for various reasons sometime during their lifetime. How this process has been researched and documented by various researchers is covered in this thesis, showing how the insights and lessons from various Information Seeking Models in the literature have informed and enriched this study. These models provide a good understanding of the study field and frameworks to explain the different elements of the information seeking process. All available Information Seeking Models, however, are developed based on the assumption that information seeking is performed by people with sight. How applicable these Information Seeking Models are for people who are blind and/or visually impaired is not addressed in the research. There are a number of different realities for a blind and visually impaired person seeking information, e.g. the accessibility of the technology to access the information, the accessibility of the information once it is located, the availability of technologies to assist the blind and visually impaired person to enable him/her to seek information, the availability of other people to assist the blind and visually impaired person during the information seeking process are just some of the challenges not addressed by existing Information Seeking Models. The purpose of this study is therefore to give an overview of existing Information Seeking Models and then to focus on the two leading researchers in the field, i.e. C. Kuhlthau and T.D. Wilson. These models of the information seeking process were contextualised and assessed in relation with the information needs model of N. Moore who researched the information needs of blind and visually impaired people. Based on the work of the three researchers a survey instrument was developed to determine the information seeking process of Grade 12 learners at five South African Schools for the Blind. Since Grade 12 learners must decide about their future, after completing school, it was decided to research how Grade 12 learners seek information to assist them to decide about tertiary studies or work options. The study included learners who had not yet started the information seeking process in this regard. A research instrument was designed to collect data to investigate the information seeking processes of the Grade 12 learners in order to assess the extent to which they correlated with the Information Seeking Models of Kuhlthau (1991) and Wilson (1999). The qualitative research method was followed in this study which was located in a constructivist paradigm. Interviews were conducted with 43 learners at the five schools for the blind representing the total population of Grade 12 learners registered at the selected schools. The literature confirms that low population sizes are customary when researching blind and visually impaired people. Face-to-face interviews were conducted at the five schools. The findings of the interviews were analysed through a framework analysis. Thereafter, a gap analysis was conducted to determine to what extent the findings correlated to or differed from the Information Seeking Models. From this analysis seven components were identified as part of the design of the Inclusive Information Seeking Model applicable to blind and visually impaired Grade 12 learners, a major outcome of the study. A broader application of the model is suggested. This Inclusive Information Seeking Model will raise awareness and assist people working in an information environment to make the necessary provisions, to ensure that the information seeking process for blind and visually impaired people is as successful as possible with available resources

Click-Enter-Send: The Relationship Experiences of People Who are Blind or Visually Impaired in Text-Based Workspaces

Companies have increasingly turned to text-based communications to recruit, hire, and manage a distributed remote workforce. For people who are blind or visually impaired, this movement presents both challenges and opportunities for attaining and retaining employment. Does the potential isolation of telework have a negative effect on workplace relationships for people who are blind or visually impaired? Does participation in text-based workspaces mitigate stereotypes and stigmatization experienced by people with visible disabilities? Using a constructivist grounded theory framework, this study explored how people who are blind or visually impaired experience relationships in text-based workspaces. Building and maintaining social connections and networks is critical for employment success, so understanding the factors at play in text-based workplace communications is key. Interviews with 18 blind or visually impaired professionals revealed a number of ways individuals connected with colleagues, cultivated professional identity, and built extended networks. This happened despite challenges from technologies and organizational processes that failed to account for employees who are visually impaired. This investigation resulted in the development of an emergent theory and a model that can advance policies and practices for employers and for employment training and support programs.

Servicescapes seen by visually impaired travellers : Time-geography approach to servicescape research

Knowledge gaps remain in the study of servicescapes, since existing research on servicescapes tends to ignore major advances in the understanding of space and time as social phenomena. One aspect that particularly requires further study is how emerging constraints influence customers’ interactions with organized service places. The time-geography approach was therefore applied to the current servicescape research to help to identify various constraints that blind and visually disabled persons (VIPs) experienced in a certain service place and time. A complementary usage of the concept of tactics illustrated how constrained customers responded to the constraints. The overall research question - How do blind and visually impaired persons act and move in hospitality servicescapes? – was explored empirically through individual and focus group interviews and go-along observations of 56 blind and VIPs during 3.5 years. The study population was composed of residents of Sweden, Kazakhstan, and Germany. The analysis was organized into two themes – Competition of space-time projects and Tactical behavior: evaluating, mapping, and networking. This was followed by a discussion of the analysis under the two headings A scarcity of resources and A struggle for resources. This book concluded that emerging constraints are not only “created by” the organization of servicescapes, but are also due to the customers’ insufficient capabilities. The outcome of an individual’s action in service place depends on customer’s capability to overcome unexpected constraints and available resources, such as time and an access to service offerings. Some of the key findings that emerged were that blind and VIPs were not passive recipients of services but rather developed tactical strategies to navigate within poorly organized servicescapes. In so concluding the book suggests that servicescape is a place of dynamic interplay between emerging constraints and the tactical behaviors of the constrained customers

The Role of Sonification as a Code Navigation Aid: Improving Programming Structure Readability and Understandability For Non-Visual Users

Integrated Development Environments (IDEs) play an important role in the workflow of many software developers, e.g. providing syntactic highlighting or other navigation aids to support the creation of lengthy codebases. Unfortunately, such complex visual information is difficult to convey with current screen-reader technologies, thereby creating barriers for programmers who are blind, who are nevertheless using IDEs. This dissertation is focused on utilizing audio-based techniques to assist non-visual programmers when navigating through large amounts of code. Recently, audio generation techniques have seen major improvements in their capabilities to covey visually-based information to both sighted and non-visual users – making them a potential candidate for providing useful information, especially in places where information is visually structured. However, there is little known about the usability of such techniques in software development. Therefore, we investigated whether audio-based techniques capable of providing useful information about the code structure to assist non-visual programmers. The major contributions in this dissertation are split into two major parts: The first part of this dissertation explains our prior work that investigates the major challenges in software development faced by non-visual programmers, specifically code navigation difficulties. It also discusses areas of improvement where additional features could be developed in order to make the programming environment more accessible to non-visual programmers. The second part of this dissertation focuses on studies aimed to evaluate the usability and efficacy of audio-based techniques for conveying the structure of the programming codebase, which was suggested by the stakeholders in Part I. Specifically, we investigated various sound effects, audio parameters, and different interaction techniques to determine whether these techniques could provide adequate support to assist non-visual programmers when navigating through lengthy codebases. In Part II, we discussed the methodological aspects of evaluating the above-mentioned techniques with the stakeholders and examine these techniques using an audio-based prototype that was designed to control audio timing, locations, and methods of interaction. A set of design guidelines are provided based on the evaluation described previously to suggest including an auditory-based feedback system in the programming environment in efforts to improve code structure readability and understandability for assisting non-visual programmers

Surveying Persons with Disabilities: A Source Guide (Version 1)

As a collaborator with the Cornell Rehabilitation Research and Training Center on Disability Demographics and Statistics, Mathematica Policy Research, Inc. has been working on a project that identifies the strengths and limitations in existing disability data collection in both content and data collection methodology. The intended outcomes of this project include expanding and synthesizing knowledge of best practices and the extent existing data use those practices, informing the development of data enhancement options, and contributing to a more informed use of existing data. In an effort to provide the public with an up-to-date and easily accessible source of research on the methodological issues associated with surveying persons with disabilities, MPR has prepared a Source Guide of material related to this topic. The Source Guide contains 150 abstracts, summaries, and references, followed by a Subject Index, which cross references the sources from the Reference List under various subjects. The Source Guide is viewed as a “living document,” and will be periodically updated

The Process Of Obtaining And Retaining Employment Among The Vision-restricted

National estimates indicate that only a small percentage of vision-restricted individuals are employed. Identified obstacles to employment include lack of access to assistive technology, inadequate transportation, and negative attitudes of potential employers. A constructivist Grounded Theory methodology was used to gain an in-depth understanding of what people with vision-restrictions, who perceived that they are successfully employed, considered to be fundamental in the search for employment. Three themes emerged from the analysis of their responses: facing and negotiating barriers, the cyclical process of seeking and keeping employment, and settling for second best. As a person with a vision-restriction, I am uniquely situated to relate to participants and to gain insight into their employment experiences. Such knowledge may enable service providers to assist clients in implementing successful strategies, may promote attitudinal changes among employers, and may inspire job seekers not to abandon their search
