The graphic representation method as the universal-designed touch-screen interface for visually impaired people

这项研究得到了2009财政年度至2010财政年度的资助。本研究的目的是提出一种新颖的图形表示方法，以触摸和声音作为视障人士通用设计的触摸屏界面。所提出的方法和接口是开发插件的基本技术，帮助盲人使用普通的大规模生产的触摸屏计算机设备，如智能手机和iPad。我们的想法是如此简单，音乐音阶引导用户的手指跟踪图形和记忆他们在触摸屏上的位置。四个接口的基础上的想法，实现和视障人士的评价。

This research has been supported by the grant from FY2009 to FY2010. The research goal is to propose the novel graphic representation method with touch and sound as the universal designed touch-screen interface for visually impaired people. The proposed method and interfaces are basic techniques for developing plug-ins which help blind people to use ordinary mass-produced computer devices with touch-screens, such as smart-phones and iPad. Our idea is so simple that musical scales guide users' finger to trace graphics and to memorize their position on the touch-screen. Four interfaces based on the idea were implemented and evaluated by visually impaired people.
