虚拟现实系统的开发需要反复的规范，实施和评估。由于沉浸式VR系统的正确评估需要佩戴许多设备的繁琐过程，因此在实施和评估阶段之间存在时间和空间差距，这通常会导致开发过程中的延迟和效率低下。为了克服这个差距，已经有几种方法来构建或建模虚拟环境中的虚拟世界（或对象）的物理方面。然而，建模他们的行为仍然是在传统的（2D）programmingenvironments.This进行的，本文提出了一个交互模型，和接口指定（和修改）对象的行为，在虚拟环境中，基于一个底层的虚拟对象模型。该交互模型遵循演示编程的概念，并在此基础上，我们已经建立了一个名为PiP（Programming virtual object behavior in virtual reality Program）的系统，用户可以创建，修改，测试和保存对象行为。我们举例说明使用PIP构建的交互式虚拟世界，并讨论其优点和缺点作为一个内容开发平台。
Development of virtual reality systems requires iterations of specification, implementation and evaluation. Since correct evaluations of immersive VR systems require the tedious process of wearing many devices, there exist both temporal and spatial gaps between the implementation and evaluation stage, and this usually causes delay and inefficiency in the development process. In order to overcome this gap, there have been several approaches to constructing or modeling the physical aspects of the virtual world (or objects) within the virtual environment. However, modeling their behaviors is still carried out in conventional (2D) programming environments.This paper proposes an interaction model, and interfaces for specifying (and modifying) object behavior, within the virtual environment, based on an underlying virtual object model. The interaction model follows the concept of programming by demonstration, and based on it, we have built a system called the PiP (Programming virtual object behavior in virtual reality Program) "in" which a user can create, modify, test, and save object behaviors. We illustrate examples of interactive virtual worlds constructed using the PiP, and discuss its merits and shortcomings as a content development platform.
