项目摘要

We have investigated two application domains of multi-focus zooming interfaces, that is, interactive visualizations of declarative data-flow visual program executions and hierarchical directory structures. In addition, for future enhancement of our zooming interfaces, we have been doing basic research on human-computer interactions beyond traditional desktop environments.1. We have implemented an interactive browser with a multi-focus zooming interface, which provides a support for navigation of a huge and static diagram, representing an entire execution of a declarative data-flow visual program. This browser can effectively put multiple foci on arbitrary portions of a diagram and render an image consisting of not only those focal points but also their overall contexts. Also, based upon the notion of a "trace view,"we have proposed techniques to simultaneously depict asynchronous events such as inputs and outputs of a process and to illustrate dependences among processes.2. We have implemented a prototype system that can interactively visualize a directory structure through a multi-focus zooming interface. This system provides a support for three sorts of navigation patterns, that is, navigation via parent-child links, keywords, and similarities. An important feature of this system is to show the enclosing directories of foci as contexts.3. For the purposes of future enhancement of our zooming interfaces, we have investigated fundamental interaction techniques in wall display and mixed reality environments.

我们已经调查了两个应用领域的多焦点缩放接口，即，声明性数据流可视化程序执行和层次目录结构的交互式可视化。此外，为了将来增强缩放界面，我们一直在进行传统桌面环境之外的人机交互基础研究。1.我们已经实现了一个交互式浏览器的多焦点缩放界面，它提供了一个巨大的和静态的图表导航的支持，表示一个声明性的数据流可视化程序的整个执行。这个浏览器可以有效地将多个焦点放在图表的任意部分，并呈现一个不仅由这些焦点组成的图像，而且还包括它们的整体上下文。此外，基于“跟踪视图”的概念，我们提出了同时描述异步事件（例如流程的输入和输出）并说明流程之间的依赖关系的技术。2.我们已经实现了一个原型系统，可以交互式可视化的目录结构，通过多焦点缩放界面。该系统提供了三种导航模式的支持，即通过父子链接，关键字和相似性导航。这个系统的一个重要特点是显示焦点的封闭目录作为上下文。为了将来增强我们的缩放界面，我们研究了墙壁显示和混合现实环境中的基本交互技术。
