本文描述了一种名为 Digitizer Auditory Graphfia 声音处理软件工具的辅助技术的设计目标、设计方法和用户测试，该工具允许用户使用光学输入设备（例如网络摄像头、数码相机、手机摄像头）上传或拍摄线图图像，然后听到数字化图形图像的听觉图。该技术使视障学生能够以图形方式多模式显示信息。初步评估结果表明，视觉障碍者和视力正常的人都可以通过听听觉图形来理解图形的模式，并且光学输入使他们能够简单快速地输出结果。
This paper describes the design goal, design approach, and user testing of an assistive technology called Digitizer Auditory Graphfia sonification software tool that allows users to upload or take an image of a line graph with an optical input device (e.g., webcam, digital camera, cell phone camera) and then hear an auditory graph of the digitized graph image. This technique enables visually impaired students to have a multimodal display of the information in a graph. Preliminary evaluation results indicate that both visually impaired and sighted people can understand the patterns of graphs by listening to auditory graph, and optical input allows them to have simple and fast output results.
