Title	Scripting Method Based on Temporal Intervals for Designing Interactive Systems
Author	K. Mase, C. Pinhanez, and A. Bobick
Abstract	Multimodal interfaces are often used in immersive interactive systems, which integrate many sensors and actuators, to provide situated and robust interactions. This paper presents a novel programming paradigm, Interval Scripts, which has the temporal flexibility in designing event handling and actuator control. In such interval scripts, the system's designer attaches sensor and actuator routines to time intervals and the development of the interaction is defined by local precedence relations provided by the designer of the system. Interval scripts have the potential to express more clearly the complex structure of time events in immersive environments where the user's actions span non-punctual intervals of time, making the use of event-based interaction design very difficult. This paper examines in detail two scenes implemented in a prototype interactive system called SingSong.
