  • Poster for CHIIR 2017: Visual Analysis of Dyslexia on Search  
    In category: Posters.
    Uploaded by Andrew MacFarlane on 21 March 2017.

    A key problem in the field of search interfaces is dyslexic users interaction with the UI. Dyslexia is a widespread specific learning difficult (SpLD) (10% of any population is estimated to have this cognitive disability) which is under researched in the field of information retrieval. The focus here is an analysis of the User Interface (UI) for search, using visual analytical methods on eye tracking data to examine the difference between control and dyslexic searchers. We use a n umber of visual analytic methods including path similarity analysis (PSA) and clustering of time Intervals to demonstrate both similarities and differences between the user groups. Observations of videos are used to augment the visualizations. Results demonstrate a clear difference between the user groups, and a clear memory effect on the user of search interfaces is shown – this is a key contribution of this paper. We examine the results using of theories of dyslexia, contributing also to the field of dyslexia and search.
