An Implementation of Multi-Modal Game Interface Based on PDAs

Abstract

In computer animation and interactive computer games, gesture and speech modality can be a powerful interface between humans and computers. In this paper, we propose a personal digital assistant (PDA)- based multi-modal network game interface using speech, gesture and touch sensations. To verify the validity of our approach, we implement a multi-modal omok game using TCP/IP on a PDA network. The experimental results using the proposed multi-modal network game resulted in an average recognition rate of 97.4%, and accordingly as the weaknesses of uni- modality, such as incorrect command processing by recognition error, are offset by the strengths of other modalities, the user can enjoy a more interactive mobile game interface in any given environment.
