With this work, we propose and validate a new service system in the context of Wayfinding services to improve the SmartCities mechanism: smart mobility, smart people, smart governance and smart living services. Steering and navigation tasks through an environment constitute an essential activity in our daily lives. They have a high degree of practical value in a variety of domains, such as public area design, architectural Wayfinding, geo-positioning and navigation, as well as urban planning and environmental design. At times, people with a visual impairment may also have problems in navigating autonomously and without personal assistance, especially in unknown environments (outdoor and indoor) using a smartphone. There could also be emergency situations in which the receiving of information in real time could be crucial. People with motor disabilities usually need information to avoid environments with obstacles, to arrive at a target or to manage touchscreens in daily activities and different environments. The use of landmarks is therefore vitally important in human navigation. Wayfinding systems must change, given that according to the United Nations (UN) Development Program, people with a disability represent around 10% of the world’s population, which is approximately 650 million people. Additionally, according to the World Health Organization, the world’s population of people 60 years of age and older has doubled since 1980 and is predicted to reach 2 billion by 2050. Most Wayfinding applications in the Smartphone market suffer from at least one of the following problems: the information is not dynamic, the design is not universal or the interface is not adapted to different users and preferences. Accordingly, apps do not currently have a universal design. The GAWA platform provides a universal and accessible solution to manage Wayfinding applications that focuses on people with a disability in outdoor and indoor environments in Smartcities. According to the results, the platform could be used for performing activities in their daily lives. 相似文献

网络资源用户中具在残障的群体，他们或者在认知方面存在障碍（如失聪、听力障碍、失明、视力障碍等）或由于衰老而引起残障，而这些身体上或认知上的障碍意味着他们在浏览使用网络信息的时候需要有适合他们需要的特殊元数据和界面。尽管每个人的残障情况各有不同，但是每一种情况都会有一些共同点。通过建立元数据应用纲要来对这共同点进行描述，使信息系统能够根据元数据纲要描述的不同来调节网络信息的显示和功能，同时又保证残障用户的隐私权，是本文的主要内容。本文作者为都柏林元数据提出了一个新的元素：DC：Adaptability，用这个元素来描述具有残障的个人（匿名）元数据纲要，并且为该元素提出了一套规范词，包括显示、控制、内容三个大类共22个规范用词，这些规范词照顾到了用户的个人隐私权，不对残障种类和个人需要或偏好作任何暗示。作者还解释了该纲要不仅可以用来为残障用户提供个人化的信息显示和操作，而且也可以用来为一般用户提供个人化的系统显示。 相似文献

ABSTRACTSonification is the use of non-speech audio to convey information. In this article, sonifications are representations of plots aimed at improving the accessibility of teaching materials. The electronic nature of sonifications means that they can be deployed to students via teaching interfaces such as virtual learning environments. We describe a two-phase study that explores sonifications of plots as a teaching tool in the context of distance learning in STEM. The overall objective of these two phases was to begin to assess the suitability of audio versions of graphs as a teaching tool for non-sighted and sighted students. In the first phase the effectiveness of sonifications within a small group of participants who took part in activities like those encountered in a distance learning setting was explored. We found that even though sonifications were new to them, participants were able to use them to gain impressions of the corresponding plots. The second phase deployed sonifications to all students on an Open University (OU) module. Although many of the students who chose to respond did so negatively, some found the sonifications an interesting augmentation of the plot. Overall, we demonstrate that for a subset of students, information in a plot can be communicated using sonifications. 相似文献

In light of the growing population of students with disabilities at colleges and universities worldwide, faculty development connected to accessible teaching is of paramount importance. Drawing from the existing literature and from the results of a qualitative study of educational accessibility at one Canadian university, this article offers a series of recommendations for academic developers hoping to establish effective development initiatives focused on accessible teaching and learning. Key issues considered include the need to support instructors in translating principles of inclusive teaching into practice, the value of discussion-based approaches that take up difficult questions about minimum standards, and the question of whether development initiatives should be discipline-specific or interdisciplinary, mandatory or optional. Recommendations for further research are also discussed. 相似文献

基于WCAG2.0政府网站可访问性评价研究 总被引：1，自引：0，他引：1
在对国内外网站可访问性的法规与标准以及相关评价研究进行综述的基础上,利用Achecker在线软件工具对4个公认的世界城市和我国北京、上海的政府网站进行基于WCAG2.0级别A标准的可访问性检测。从网页平均错误数来看,上海错误数最少,巴黎和北京有待改进;从网站首页检测结果来看,六城市政府网站的首页均没有通过检测;从错误类型来看,各城市网站的错误主要集中在某一种或两种类型上;六城市政府网站的可访问性排名依次为：伦敦、东京、上海、纽约、巴黎、北京。根据检测结果提出如下建议：重视首页的可访问性;改进终端页面;有针对性地改正技术错误;定期检测和改进;提高用户参与度。图1。表5。参考文献31。 相似文献

指称偏误影响着作文的连贯性和语篇的质量。文章选取部分中外学生的英汉二语作文中的作文例句作为范例,对六种指称偏误进行比较,并分析其成因。文章指出,指称词的可及度影响着指称手段的选择;英汉二语学习者在进行二语写作时所产生的指称偏误,是由于不了解英汉两种语言之间在指称语码转换表现形式上的不同所造成的;六种指称偏误的误用程度有所不同;指称偏误类型,在一定程度上,能反映学生的语言表达水平。 相似文献

This article examines whether Section 255 of the 1996 Telecommunications Act achieves accessibility for people with disabilities. Taking the interest group approach, it shows that the Federal Communications Commission (FCC) implemented Section 255 in a way that is favorable to the telecommunications industry and not to people with disabilities. The FCC's regulations only encourage the telecommunication industry to consider accessibility issues for people with disabilities. This proindustry regulatory bias is in keeping with the established pattern of policymaking in other areas concerning people with disabilities. The paper argues that if the FCC continues to rely on the voluntary efforts of the industry, people with disabilities will not enjoy benefits of access to telecommunications systems. 相似文献
