Abstract
The notion of Ability-Based Design, put forth by Wobbrock et al. [80, 82] as a solution to the challenge of creating accessible technology, has been discussed in human-computer interaction research now for over a decade. However, despite being cited as influential on various projects, the concept still lacks a general characterization of how to implement its required focus on abilities. In particular, it lacks a formulation of how to perceive and model users within an articulated design process. To address this shortcoming, we rely on conceptual user modeling to examine Ability-Based Design and propose a characterization of it that is not dependent upon a specific project or research effort but that enables the ability-based design of new technologies in a systematic manner. Our findings show that Ability-Based Design’s focus on abilities requires important changes in typical user modeling approaches that cannot be met with current techniques. Based on the challenges identified through our analysis, we propose a first modification not only of current user modeling but also of current requirements analysis approaches to address abilities and their intertwined dependencies with tasks and contexts as core elements of conceptual models in Ability-Based Design. We thereby demonstrate not only the complexity of modeling users’ abilities, but also draw out promising ideas and perspectives for future research, emphasizing the need for future evaluative work on our approach.
期刊介绍:
Computer and information technologies have re-designed the way modern society operates. Their widespread use poses both opportunities and challenges for people who experience various disabilities including age-related disabilities. That is, while there are new avenues to assist individuals with disabilities and provide tools and resources to alleviate the traditional barriers encountered by these individuals, in many cases the technology itself presents barriers to use. ACM Transactions on Accessible Computing (TACCESS) is a quarterly peer-reviewed journal that publishes refereed articles addressing issues of computing that seek to address barriers to access, either creating new solutions or providing for the more inclusive design of technology to provide access for individuals with diverse abilities. The journal provides a technical forum for disseminating innovative research that covers either applications of computing and information technologies to provide assistive systems or inclusive technologies for individuals with disabilities. Some examples are web accessibility for those with visual impairments and blindness as well as web search explorations for those with limited cognitive abilities, technologies to address stroke rehabilitation or dementia care, language support systems deaf signers or those with limited language abilities, and input systems for individuals with limited ability to control traditional mouse and keyboard systems. The journal is of particular interest to SIGACCESS members and delegates to its affiliated conference (i.e., ASSETS) as well as other international accessibility conferences. It serves as a forum for discussions and information exchange between researchers, clinicians, and educators; including rehabilitation personnel who administer assistive technologies; and policy makers concerned with equitable access to information technologies.
