更好地访问在线信息图形是盲人或视力严重受损的人的迫切需要。我们提出了一个新的模型，在线信息图形的无障碍演示，并展示其用于呈现平面图。虽然越来越多地在网上提供平面图，但盲人最多只能得到高层次的文字描述。这使得他们很难理解平面图上物体的空间排列。我们的新方法为用户提供了更好的访问此类计划的机会。用户可以通过使用Web服务从在线平面图图像快速且独立地自动生成平面图的可访问版本。这将生成一个简化的图形，显示原始平面图中的房间、墙壁、门和窗以及文本概述。无障碍楼层平面图通过音频反馈呈现在iPad上。当用户触摸屏幕上的图形元素时，他们正在触摸的元素由语音和非语音音频描述，以帮助他们导航图形。
Better access to on-line information graphics is a pressing need for people who are blind or have severe vision impairment. We present a new model for accessible presentation of on-line information graphics and demonstrate its use for presenting floor plans. While floor plans are increasingly provided on-line, people who are blind are at best provided with only a high-level textual description. This makes it difficult for them to understand the spatial arrangement of the objects on the floor plan. Our new approach provides users with significantly better access to such plans. The users can automatically generate an accessible version of a floor plan from an on-line floor plan image quickly and independently by using a web service. This generates a simplified graphic showing the rooms, walls, doors and windows in the original floor plan as well as a textual overview. The accessible floor plan is presented on an iPad using audio feedback. As the users touch graphic elements on the screen, the element they are touching is described by speech and non-speech audio in order to help them navigate the graphic.
