有视觉障碍的学生很难在学术课程中学习各种概念,因为图表,图像和其他视觉对他们来说是不可访问的。为了解决这个问题,研究人员设计了交互式3D打印模型(I3M),当用户触摸模型的组件时,它会提供音频描述。在以前的工作中,I3M是在特别的基础上设计的,目前还不知道什么样的一般准则可以产生有效的I3M设计。为了解决这一差距,我们与视障教师(TVI)进行了两项研究。首先,我们领导了两个设计研讨会,有35个TVI,他们修改了样品模型并添加了互动元素。其次,我们与三个TVI合作,在迭代教学设计过程中设计了三个I3M。在这个过程的最后,TVI使用我们设计的I3M来教他们的学生。我们得出结论,I3M应该(1)具有有效的触觉特征(例如,组件之间的区别模式),(2)包含听觉和视觉内容(例如,解释性动画),以及(3)考虑教学方法(例如,在详细信息之前概述)。
Students with visual impairments struggle to learn various concepts in the academic curriculum because diagrams, images, and other visual are not accessible to them. To address this, researchers have design interactive 3D printed models (I3Ms) that provide audio descriptions when a user touches components of a model. In prior work, I3Ms were designed on an ad hoc basis, and it is currently unknown what general guidelines produce effective I3M designs. To address this gap, we conducted two studies with Teachers of the Visually Impaired (TVIs). First, we led two design workshops with 35 TVIs, who modified sample models and added interactive elements to them. Second, we worked with three TVIs to design three I3Ms in an iterative instructional design process. At the end of this process, the TVIs used the I3Ms we designed to teach their students. We conclude that I3Ms should (1) have effective tactile features (e.g., distinctive patterns between components), (2) contain both auditory and visual content (e.g., explanatory animations), and (3) consider pedagogical methods (e.g., overview before details).
