Presidential Young Investigator Award: Interactive Computer Graphics ,

主要的研究目标是调查用户和计算机之间的交互，以设计更高效的人机系统。为了实现这一目标，正在进行几项实验性研究。第一组主要涉及感知和处理计算机显示的三维图形图像的各种图像转换的理论问题。第二组研究侧重于确定柔性制造系统（FMS）中可由操作员有效监督的最优机器数量，以及跨柔性制造系统任务中操作员和计算机系统之间的最佳任务分配。第三组研究考察了专家和新手在解决需要高水平专业知识（如编程）的任务时的差异。

The main research objective is to investigate the interaction between users and computers in order to design more productive human-computer systems. To pursue this goal several experimental studies are being performed. The first set involve primarily theoretical issues in perceiving and processing computer-displayed 3-D graphical images undergoing various image transformations. The second set of studies focuses on determining the optimal number of machines in a flexible manufacturing system (FMS) which can be effectively supervised by an operator, and the optimum allocation of tasks between operators and computer systems across FMS tasks. The third set of studies examine expert-novice problem solving differences for tasks which require high levels of expertise (such as programming).
