Interactive Auditory DisplaysPI: Ming C. LinCo-PIs: Gary Bishop and Dinesh ManochaDepartment of Computer ScienceUniversity of North Carolina at Chapel HillAn auditory display utilizes sound to communicate information to a user and offers an alternative means of visualization. By harnessing the sense of hearing, audio rendering can further enhance a user's experience in a multimodal virtual world. Acoustic realism has many areas of applicability including virtual reality, computer gaming, training systems, desktop interfaces, education, and scientific visualization.We are conducting an ambitious research program to develop interactive auditory displays. Our goal is to develop new algorithms for physics-based sound synthesis and sound propagation for interactive applications including computer gaming, training systems, and enabling technologies. The approach involves the fusion of both geometry (for high frequencies) and physics (for low frequencies) to model sound propagation and the development of techniques for acoustic levels of detail. To this end we are developing efficient numerical algorithms based on domain decomposition and exploiting modern architecture features to further accelerate the overall performance. We are also evaluating the performance of our algorithms on different applications. In addition to acoustic simulation, our research is generating a fundamental scientific foundation and interactive performance methods for solving wave/sound propagation problems in highly complex domains that span many scientific and engineering disciplines.

交互式听觉显示器PI：ming C.LINCO-PI：Gary Bishop和Dinesh Manocha计算机科学系北卡罗来纳大学教堂山分校听觉显示器利用声音向用户传达信息，并提供另一种可视化手段。通过利用听觉，音频渲染可以进一步增强用户在多模式虚拟世界中的体验。声学现实主义有许多应用领域，包括虚拟现实、计算机游戏、培训系统、桌面界面、教育和科学可视化。我们正在进行一项雄心勃勃的研究计划，以开发交互式听觉显示。我们的目标是开发基于物理的声音合成和声音传播的新算法，用于交互应用，包括计算机游戏、培训系统和使能技术。该方法包括融合几何学(对于高频)和物理学(对于低频)来模拟声音传播，并开发声学细节级别的技术。为此，我们正在开发基于区域分解的高效数值算法，并利用现代体系结构特征来进一步加速整体性能。我们还在评估我们的算法在不同应用程序上的性能。除了声学模拟，我们的研究还为解决跨越许多科学和工程学科的高度复杂领域中的波/声传播问题提供了基本的科学基础和交互表演方法。
