Remote Collaborative Software Development Environments with Wall-Size Displays

我们一直在研究(1)用于两个或多个用户相互协作的大屏幕显示环境的新交互技术，以及(2)用于测试和基于组件的安全软件构造的新软件开发环境。主要成果如下：1.在大屏幕显示环境中，鼠标和键盘不是很方便的输入设备，用户经常站在显示器前面。因此，我们研究了各种笔式和语音输入法。我们已经建立了(1)基于笔的3D自由曲面和模型的输入法，(2)基于笔的动画输入法，以及(3)基于语音的光标控制方法。前两个旨在与白板大小的显示器一起使用，以协作创建3D模型和动画。与此形成对比的是，最后一种设计用于更大尺寸的显示器，这种显示器非常大，用户无法触摸到顶端边缘。我们的结论是，后一种方法同样适用于骨科损伤患者控制图形用户界面。我们计划在多显示器环境下继续这项工作。我们正在研究复杂的软件开发环境。我们已经建立了方法和实现工具，用于(1)基于静态和动态程序分析的安全软件构建，用于具有分层插件的组件模型，以及(2)在可能存在零星I/O异常的情况下的可重复性测试。

We have been doing research on (1)new interaction techniques for large format display environments where two or more users cooperate with one another and (2)new software development environments for testing and component-based secure software constructions. The following are our major achievements :1. Mice and keyboards are not convenient input devices in large format display environments, where users are often standing in front of the display. So, we have investigated into various pen-based and speech-based input methods. We have established (1) pen-based input methods for 3D free surfaces and models, (2) pen-based input methods for animations, and (3) speech-based methods for cursor control. The first two are intended to be used with whiteboard-size displays for collaborative creation of 3D models and animations. In contrast, the last one is intended to be used with larger format displays that are so large that users cannot touch the top edges. We have concluded that the last methods are also useful for orthopedically impaired to control GUI. We plan to continue the work in multi-display environments.2. We have doing research on sophisticated software development environments. We have established methods and implemented tools for (1) secure software construction, based on static and dynamic program analysis, for a component model with hierarchical plug-ins and (2) reproducible testing in the presence of possibly sporadic I/O exceptions.
