InCA: A mobile conversational agent

Abstract

InCA is a distributed personal assistant conversational agent. The front-end runs on a handheld PDA and uses facial animation and natural speech input/output to interact with the user to provide services such as appointments, e-mail and weather reports. Existing conversational character research focuses on desktop platforms, but there are obvious differences when the platform is a mobile device, the two most obvious being the limited computational power and the restrictions on input modalities. This paper discusses the architecture and implementation of InCA, which addresses these two challenges. © Springer-Verlag Berlin Heidelberg 2004.
