SteeringWheel: A Locality-Preserving Magnification Interface for Low Vision Web Browsing

論文URL: http://dl.acm.org/citation.cfm?doid=3173574.3173594

論文アブストラクト: Low-vision users struggle to browse the web with screen magnifiers. Firstly, magnifiers occlude significant portions of the webpage, thereby making it cumbersome to get the webpage overview and quickly locate the desired content. Further, magnification causes loss of spatial locality and visual cues that commonly define semantic relationships in the page; reconstructing semantic relationships exclusively from narrow views dramatically increases the cognitive burden on the users. Secondly, low-vision users have widely varying needs requiring a range of interface customizations for different page sections; dynamic customization in extant magnifiers is disruptive to users' browsing. We present SteeringWheel, a magnification interface that leverages content semantics to preserve local context. In combination with a physical dial, supporting simple rotate and press gestures, users can quickly navigate different webpage sections, easily locate desired content, get a quick overview, and seamlessly customize the interface. A user study with 15 low-vision participants showed that their web-browsing efficiency improved by at least 20 percent with SteeringWheel compared to extant screen magnifiers.

Understanding the Needs of Searchers with Dyslexia

論文URL: http://dl.acm.org/citation.cfm?doid=3173574.3173609

論文アブストラクト: As many as 20% of English speakers have dyslexia, a language disability that impacts reading and spelling. Web search is an important modern literacy skill, yet the accessibility of this language-centric endeavor to people with dyslexia is largely unexplored. We interviewed ten adults with dyslexia and conducted an online survey with 81 dyslexic and 80 non-dyslexic adults, in which participants described challenges they face in various stages of web search (query formulation, search result triage, and information extraction). We also report the findings of an online study in which 174 adults with dyslexia and 172 without dyslexia rated the readability and relevance of sets of search query results. Our findings demonstrate differences in behaviors and preferences between dyslexic and non-dyslexic searchers, and indicate that factoring readability into search engine rankings and/or interfaces may benefit both dyslexic and non-dyslexic users.

日本語のまとめ:

失読症者に対してのウェブ検索における機能は少ない。この論文では失読症者、非失読症者を対象に調査を行なった。その結果から検索エンジンやインターフェースの読みやすさは、両方のユーザーに利益をもたらす可能性があることを示した。

Weaving Lighthouses and Stitching Stories: Blind and Visually Impaired People Designing E-textiles

論文URL: http://dl.acm.org/citation.cfm?doid=3173574.3174044

論文アブストラクト: We describe our experience of working with blind and visually impaired people to create interactive art objects that are personal to them, through a participatory making process using electronic textiles (e-textiles) and hands-on crafting techniques. The research addresses both the practical considerations about how to structure hands-on making workshops in a way which is accessible to participants of varying experience and abilities, and how effective the approach was in enabling participants to tell their own stories and feel in control of the design and making process. The results of our analysis is the offering of insights in how to run e-textile making sessions in such a way for them to be more accessible and inclusive to a wider community of participants.
