Expressive haptics for enhanced usability of mobile interfaces in situations of impairments
Designing for situational awareness could lead to better solutions for
disabled people, likewise, exploring the needs of disabled people could lead to
innovations that can address situational impairments. This in turn can create
non-stigmatising assistive technology for disabled people from which eventually
everyone could benefit. In this paper, we investigate the potential for
advanced haptics to compliment the graphical user interface of mobile devices,
thereby enhancing user experiences of all people in some situations (e.g.
sunlight interfering with interaction) and visually impaired people. We explore
technical solutions to this problem space and demonstrate our justification for
a focus on the creation of kinaesthetic force feedback. We propose initial
design concepts and studies, with a view to co-create delightful and expressive
haptic interactions with potential users motivated by scenarios of situational
and permanent impairments.Comment: Presented at the CHI'19 Workshop: Addressing the Challenges of

Ability-Based Design: Concept, Principles and Examples
Current approaches to accessible computing share a common goal of making technology accessible to users with disabilities. Perhaps because of this goal, they may also share a tendency to centralize disability rather than ability. We present a refinement to these approaches called ability-based design that consists of focusing on ability throughout the design process in an effort to create systems that leverage the full range of human potential. Just as user-centered design shifted the focus of interactive system design from systems to users, ability-based design attempts to shift the focus of accessible design from disability to ability. Although prior approaches to accessible computing may consider users’ abilities to some extent, ability-based design makes ability its central focus. We offer seven ability-based design principles and describe the projects that inspired their formulation. We also present a research agenda for ability-based design.Engineering and Applied Science
Crossmodal spatial location: initial experiments
This paper describes an alternative form of interaction for mobile devices using crossmodal output. The aim of our work is to investigate the equivalence of audio and tactile displays so that the same messages can be presented in one form or another. Initial experiments show that spatial location can be perceived as equivalent in both the auditory and tactile modalities Results show that participants are able to map presented 3D audio positions to tactile body positions on the waist most effectively when mobile and that there are significantly more errors made when using the ankle or wrist. This paper compares the results from both a static and mobile experiment on crossmodal spatial location and outlines the most effective ways to use this crossmodal output in a mobile context
Rethinking access to address the digital divide in news
Professional project report submitted in partial fulfillment of the requirements for the degree of Masters of Arts in Journalism from the School of Journalism, University of Missouri--Columbia.U.S. citizens with disabilities are being denied their constitutional right to information because of barriers-to-access on news websites. Mainstream media organizations such as CNN, Fox News, NBC News, New York Times and USA Today aren't taking accessibility seriously. By prioritizing access, the media industry is treating impaired users like second-class citizens. In order for journalism to fulfill its responsibility in a democratic nation, the industry must adopt and prioritize Web accessibility.Includes bibliographic references
