Designing and Prototyping Multimodal Commands.

Abstract

Abstract: Designing and implementing multimodal applications that take advantage of several recognition-based interaction techniques (e.g. speech and gesture recognition) is a difficult task. The goal of our research is to explore how simple modelling techniques and tools can be used to support the designers and developers of multimodal systems. In this paper, we discuss the use of finite state machines (FSMs) for the design and prototyping of multimodal commands. In particular, we show that FSMs can help designers in reasoning about synchronization patterns problems. Finally, we describe an implementation of our FSM-based approach, in a toolkit whose aim is to facilitate the iterative process of designing, prototyping and testing multimodality.
