Overseas Travel to Olso and Melbourne

阅读障碍是一种普遍存在的认知特异性学习困难（SpLD），影响着大约10%的英国人口。搜索是一种广泛的、几乎无处不在的活动，有阅读障碍的用户每天都会进行搜索。在过去的十年中，HCID设计中心的工作已经开始解决这个问题，即了解阅读障碍对用户搜索行为的影响。HCID进行的一项初步试点研究考察了行为的一般模式，但随后与墨尔本大学的乔治·布坎南（George Buchanan）合作，确定了短期记忆或工作记忆对浏览结果列表和文件的影响。研究发现，有阅读障碍的用户比对照组用户判断的文档更少，这与用户的短期记忆有很强的相关性。眼动追踪数据证实了这一点，该数据显示，有阅读障碍的用户在页面上做了更多的回溯（更多的上下眼动），这表明用户正在忘记信息，不得不重新阅读文本。我们建议安排访问挪威奥斯陆城市大学和澳大利亚墨尔本大学的学者，为EPSRC正在制定的提案积累专业知识。

Dyslexia is a widespread cognitive specific learning difficulty (SpLD), effecting around 10% of the UK population. Searching is a widespread, almost ubiquitous activity which users with dyslexia will undertake on a daily basis. In the past decade, work done in the centre for HCID design has begun to tackle the issue i.e. to understand the impact of dyslexia on users search behaviour. An initial pilot study carried out by HCID examined the general pattern of behaviour, but subsequent work with George Buchanan of the University of Melbourne established the impact of short-term or working memory on browsing results lists and documents. It was found that dyslexic users where judging fewer documents than control users as being irrelevant and there was a strong correlation between this and users short-term memory. This was confirmed by using eye tracking data that showed that dyslexic users did much more backtracking on pages (more up and down eye movements), providing evident that users were forgetting information and having to re-read text. We propose to arrange visits to academics in Oslo Metropolitan University in Norway and the University in Melbourne Australia to build expertise for an EPSRC proposal under development.
