Voice and Touch Diagrams (VATagrams) Diagrams for the Visually Impaired

If a picture is worth a thousand words would you rather read the two pages of text or simply view the image? Most would choose to view the image; however, for the visually impaired this isn’t always an option. Diagrams assist people in visualizing relationships between objects. Most often these diagrams act as a source for quickly referencing information about relationships. Diagrams are highly visual and as such, there are few tools to support diagram creation for visually impaired individuals. To allow the visually impaired the ability to share the same advantages in school and work as sighted colleagues, an accessible diagram tool is needed. A suitable tool for the visually impaired to create diagrams should allow these individuals to: 1. easily define the type of relationship based diagram to be created, 2. easily create the components of a relationship based diagram, 3. easily modify the components of a relationship based diagram, 4. quickly understand the structure of a relationship based diagram, 5. create a visual representation which can be used by the sighted, and 6. easily accesses reference points for tracking diagram components. To do this a series of prototypes of a tool were developed that allow visually impaired users the ability to read, create, modify and share relationship based diagrams using sound and gestural touches. This was accomplished by creating a series of applications that could be run on an iPad using an overlay that restricts the areas in which a user can perform gestures. These prototypes were tested for usability using measures of efficiency, effectiveness and satisfaction. The prototypes were tested with visually impaired, blindfolded and sighted participants. The results of the evaluation indicate that the prototypes contain the main building blocks that can be used to complete a fully functioning application to be used on an iPad

Enabling audio-haptics

Teaching strategies used with a blind student in a bilingual bachelor program at Universidad Tecnológica de Pereira

Se encontró que no hay suficiente información, entrenamiento para profesores, materiales, publicaciones, planes de bilingüismo o investigaciones que guíen el proceso de aprendizaje de estudiantes ciegos en contextos bilingües. Esta es la razón por la cual los profesores han tenido que crear sus propias estrategias de enseñanza en un proceso constante de ensayo y error. Este estudio de caso cualitativo se preocupó por la falta de importancia que se le ha asignado a la población ciega en el campo educativo. Por esto, el objetivo de este proyecto fue encontrar estrategias de enseñanza para incluir al participante ciego en aulas de clase regulares de un programa bilingüe. Este proyecto se llevó a cabo en la Universidad Tecnológica de Pereira con un grupo de cuatro profesores seleccionados por medio del muestreo no probabilístico debido al enfoque cualitativo del presente estudio. Adicionalmente, el estudiante ciego de la Licenciatura en Bilingüismo con Énfasis en Inglés fue escogido a través del muestreo por conveniencia debido a que él era el único estudiante ciego de este programa

Tools in and out of sight : an analysis informed by Cultural-Historical Activity Theory of audio-haptic activities involving people with visual impairments supported by technology

The main purpose of this thesis is to present a Cultural-Historical Activity Theory (CHAT) based analysis of the activities conducted by and with visually impaired users supported by audio-haptic technology.This thesis covers several studies conducted in two projects. The studies evaluate the use of audio-haptic technologies to support and/or mediate the activities of people with visual impairment. The focus is on the activities involving access to two-dimensional information, such as pictures or maps. People with visual impairments can use commercially available solutions to explore static information (raised lined maps and pictures, for example). Solu-tions for dynamic access, such as drawing a picture or using a map while moving around, are more scarce. Two distinct projects were initiated to remedy the scarcity of dynamic access solutions, specifically focusing on two separate activities.The first project, HaptiMap, focused on pedestrian outdoors navigation through audio feedback and gestures mediated by a GPS equipped mobile phone. The second project, HIPP, focused on drawing and learning about 2D representations in a school setting with the help of haptic and audio feedback. In both cases, visual feedback was also present in the technology, enabling people with vision to take advantage of that modality too.The research questions addressed are: How can audio and haptic interaction mediate activ-ities for people with visual impairment? Are there features of the programming that help or hinder this mediation? How can CHAT, and specifically the Activity Checklist, be used to shape the design process, when designing audio haptic technology together with persons with visual impairments?Results show the usefulness of the Activity Checklist as a tool in the design process, and provide practical application examples. A general conclusion emphasises the importance of modularity, standards, and libre software in rehabilitation technology to support the development of the activities over time and to let the code evolve with them, as a lifelong iterative development process. The research also provides specific design recommendations for the design of the type of audio haptic systems involved

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.

AN EXPLORATORY STUDY OF THE ASSISTIVE TECHNOLOGY KNOWLEDGE, SKILLS, AND NEEDS AMONG SPECIAL EDUCATION TEACHERS AND RELATED SERVICE PERSONNEL

Federal legislation, professional standards, and school district initiatives mandate or support the consideration and application of assistive technology (AT) devices and services for students with disabilities. It is not known if practitioners in the field have the knowledge and skills required to successfully implement AT and AT services as intended. This was an exploratory study to describe and compare the level of AT knowledge among special education professionals and related service providers, identify AT training needs, and determine staff perceptions of the availability and effectiveness of AT technical assistance and support within a school system that serves a large number of parents serving in the military. The study was implemented with descriptive and inferential statistical techniques employed through a self-administered web-based questionnaire. Of the 87 professionals randomly selected, 42 participated. Special education professionals indicated a lack of essential skills and knowledge on selected AT knowledge and skill measures and current AT practices do not meet established AT quality indicators. Each professional had AT knowledge specific to their profession, but the quality and depth of the AT knowledge was similarly limited. The findings question the current effectiveness of existing AT training, policy, and supports across professional disciplines. Results suggested this is in part due to a lack of operational device knowledge and skills compounded by uncertainty of district AT procedures and policy for low and high assistive technology. Timely technical support and professional access to AT Lending Libraries were identified as interventions currently working. The results support a growing body of research in the field of AT regarding the lack of knowledge and skills of special education and related service providers. These results have implications for pre-service AT preparation programs, in-service trainings, and district policy and infrastructure support
