Abstract

We describe an architecture for coping with latency and asynchrony of multisensory events in interactive virtual environments. We propose to decompose multisensory interactions into a series of discrete, perceptually significant events, and structure the application architecture within this event-based context. We analyze the sources of latency, and develop a framework for event prediction and scheduling. Our framework decouples synchronization from latency, and uses prediction to reduce latency when possible. We evaluate the performance of the architecture using vision-based motion sensing and multisensory rendering using haptics, sounds, and graphics. The architecture makes it easy to achieve good performance using commodity off-the-shelf hardware.
分布式交互式多感官渲染的事件体系结构
我们描述了一种在交互式虚拟环境中处理多感官事件的延迟和异步的体系结构。我们建议将多感官交互分解为一系列离散的、感知上重要的事件,并在这种基于事件的上下文中构建应用程序架构。我们分析了延迟的来源,并开发了一个事件预测和调度框架。我们的框架将同步与延迟解耦,并在可能的情况下使用预测来减少延迟。我们使用基于视觉的运动传感和使用触觉、声音和图形的多感官渲染来评估该架构的性能。该体系结构使得使用现成的商品硬件很容易实现良好的性能。
