This project investigates combined visual and haptic (touch) interfaces to display multi-dimensional data generated by computer models of physical systems. The focus is on data features that are difficult to convey visually, such as scalar data which fills volumes, vector fields, and tensor fields. First, tests are conducted to better understand the perception of haptic rendering elements: virtual surfaces and constraints, forces and torques, and mechanical impedances. Second, new haptic rendering modes are developed which can convey multi- dimensional data via combinations of haptic rendering elements. These modes are tested using representative visualization problems in fluid dynamics, electromagnetics, and solid mechanics. Third, visualization puzzles are developed which quantify the perceptual added value of haptic rendering modes. Both cooperative and complementary visual/haptic rendering are explored. The project seeks to discover synergistic rendering modes which produce understanding more easily than visual rendering alone. An improved visual/haptic interface enables intuitive debugging of computer models, efficient visualization of modeling results, and improved physical understanding. Such a capability benefits the conduct of scientific research in many fields, the design and analysis of engineered systems, and the education of future scientists and engineers.

该项目研究组合视觉和触觉（触摸）界面，以显示物理系统计算机模型生成的多维数据。 重点是难以视觉传达的数据特征，例如填充体积的标量数据、向量场和张量场。 首先，进行测试是为了更好地理解触觉渲染元素的感知：虚拟表面和约束、力和扭矩以及机械阻抗。 其次，开发了新的触觉渲染模式，可以通过触觉渲染元素的组合来传达多维数据。 这些模式使用流体动力学、电磁学和固体力学中的代表性可视化问题进行测试。 第三，开发了可视化谜题，量化触觉渲染模式的感知附加值。 探索了合作和互补的视觉/触觉渲染。 该项目旨在发现协同渲染模式，比单独的视觉渲染更容易产生理解。 改进的视觉/触觉界面可以直观地调试计算机模型，有效地可视化建模结果，并提高物理理解。 这种能力有利于许多领域的科学研究、工程系统的设计和分析以及未来科学家和工程师的教育。
