An Interactive Whiteboard Environment

9312570 Vander该项目将开发演示性的可视化编程技术，并确定程序员在哪些环境下更喜欢它们而不是文本编程技术。将提供一个交互式的双视图环境，用户可以通过操作具体的图形、数据结构示例或通过在文本编辑器中输入代码来创建程序。用户将能够创建日志质量的数据结构图片，如数组、列表、树和图形，填充示例值。该系统将使用各种推理策略来构造合适的通用代码。用户将能够在可视化和文本编辑器之间来回切换，使用最自然的表示方式。通过同时提供可视化和文本表示，应该可以确定程序员认为本质上是文本的那些操作。最终，这些观察应该允许构建更好的编程环境，提供创建程序的替代方法。＊＊＊

9312570 Vander This project will develop demonstrational, visual programming techniques and determine in which contexts programmers prefer them to textual programming techniques. An interactive, two-view environment will be provided in which users can create programs by manipulating concrete pictorial, examples of data structures or by entering code into a textual editor. Users will be able to create journal- quality pictures of data structures, such as arrays, lists, trees, and graphs, fill in example values. The system will use various inferencing strategies to construct appropriate general-purpose code. Users will be able to move back and forth between the visual and textual editors, using whichever representation is most natural. By providing both a visual and a textual representation, it should be possible to determine those operations which a programmer views as intrinsically textual. Ultimately these observations should allow better programming environments to be built that provide alternative ways of creating programs. ***
