Human Factors and Design Issues in Multimodal (Speech/Gesture) Interface

Multimodal interfaces are the emerging technology that offers expressive, transparent, efficient, robust, and mobile human-computer interaction. In this paper, we described the speech/gesture based multimodal interface systematically from the human factors point of view. To design more practical and efficient multimodal interface, human factors issues such as user modeling, usability studies, speech and gesture interaction/integration, and redundancy are discussed. This paper can be helpful to the researchers in the field of study that enhances the performance of multimodal interaction.
