More than Words: The Impact of Memory on How Undergraduates with Dyslexia Interact with Information

Despite the prevalence of dyslexia and the challenges it poses for seeking, assessing and using information, there has been relatively little research on the challenges people with dyslexia face when interacting with information. What existing research there is has mostly focused on the impact on information comprehension and spelling. However, people with dyslexia often face considerable memory impairment that can affect their learning. This paper reports findings from retrospective think-aloud (RTA) observations with 13 undergraduates with dyslexia, focusing on the memory-related barriers they face and the workarounds they use to overcome these barriers. An enhanced understanding of the full range of barriers faced by information-seekers with dyslexia can inform the design of dyslexia-aware digital information environments and information literacy programs. These can ‘level the information playing field’ by helping to break down barriers to information and, in turn, to knowledge creation

Dyslexia and password usage:accessibility in authentication design

Governments and businesses are moving online with alacrity, driven by potential cost savings, changing consumer and citizen expectations, and the momentum towards general digital provision. Services are legally required to be inclusive and accessible. Now consider that almost every online service, where people have to identify themselves, requires a password. Passwords seem to be accessible, until one considers specific disabilities, one of which can lead to many challenges: dyslexia being a case in point. Dyslexia is associated with word processing and retention difficulties, and passwords are essentially words, phrases or alphanumeric combinations. We report on a literature review conducted to identify extant research into the impact of dyslexia on password usage, as well as any ameliorations that have been proposed. We discovered a relatively neglected field. We conclude with recommendations for future research into the needs of a large population of dyslexics who seem to struggle with passwords, in a world where avoiding passwords has become almost impossible. The main contribution of this paper is to highlight the difficulties dyslexics face with passwords, and to suggest some avenues for future research in this area

Experimental Methods in IIR: The Tension between Rigour and Ethics in Studies Involving Users with Dyslexia

Designing user studies in the interactive information retrieval (IIR) paradigm on people with impairments may sometimes require different methodological considerations than for other users. Consequently, there may be a tension between what the community regards as being a rigorous methodology against what researchers can do ethically with their users. This paper discusses issues to consider when designing IIR studies involving people with dyslexia, such as sampling, informed consent and data collection. The conclusion is that conducting user studies on participants with dyslexia requires special considerations at all stages of the experimental design. The purpose of this paper is to raise awareness and understanding in the research community about experimental methods involving users with dyslexia, and addresses researchers, as well as editors and reviewers. Several of the issues raised do not only apply to people with dyslexia, but have implications when researching other groups, for instance elderly people and users with learning, cognitive, sensory or motor impairments

Mobile search made easier: An ability-based mobile search prototype for people with dyslexia

Although 1 person in 14 has dyslexia, most search interfaces are designed based on a ‘one-size-fits-all’ approach, creating inequity for neurodiverse searchers. This is also the case for mobile search, which accounts for most Google searches. While existing research has found search typically presents greater challenges for people with dyslexia, no prior work has examined how best to support them when searching on mobile devices. Rather than focus on addressing their search difficulties, we adopted an ability-based design approach. This involved designing a prototype, based on modifications to Google’s mobile SERPs, aimed at enhancing their abilities – identified through interviews and observations with mobile searchers with dyslexia. A user evaluation found several of the modifications were useful; they supported searchers with dyslexia in making relevance judgements and boosted their resilience and self-efficacy. Based on these findings, we propose four broad design principles for mobile search interface design. This research provides valuable insight into how to better support mobile searchers with dyslexia that can inform IIR research and design. It also demonstrates the potential of ability-based design approaches in supporting neurodiverse searchers
