Research on interactive visual programming environment

以一种并行逻辑编程语言为目标编程语言，进行了交互式可视化编程环境的研究，在交互式可视化编程环境中，用户可以直接从工作站输入图形生成程序，而不需要使用文本。他还可以可视化地执行或调试程序。我们开发了图形编程(PP)，这是一系列的可视化编程环境。ViewPP使用图形绘制算法可视化程序执行。PP-PAD是一个基于集成的单窗口环境的编程环境，其中使用单窗口而不是多窗口。程序的编辑和执行都是在单个窗口上连续进行的。为了开发处理视觉系统的基本技术，我们开展了可视化解析器生成器EVIS的研究。关注三维显示技术，提出了3D-PP三维可视化编程系统3D-PP。程序元素，如目标和原子，用3D图形表示。程序的执行也通过3D图形的变换来表示。

We carried out the research on interactive visual programming environment, assuming a parallel logic programming language as our target programming language.In interactive visual programming environment, a user can generate a program by inputting figures directly from a workstation without using texts. He can also execute or debug a program visually.We have developed PP (Pictorial Programming) which are the series of visual pro- gramming environments. ViewPP visualizes program execution using graph drawing algorithms. PP-pad is a programming environment based on an integrated single en- vironment, where a single window is used instead of multi windows. Both of program editing and execution are carried out continuously on the single window.We carried out the research on visual parser generator "Eviss" in order to develop the elementary technique for handling visual systems.Paying attention to the three dimensional display technique, we have proposed three dimensional visual programming system 3D-PP.3D-PP visualizes a program in a 3D manner. Program elements, such as a goal and an atom, are expressed by 3D figures. Program execution is also expressed by the transformation of 3D figures.
