Resumen
The article reports that state-of-the-art multimodal interfaces can process two or more combined input modes using recognition-based technologies in order to accurately identify users or to interpret their communicative intent. There are several classes of multimodal systems that are relatively mature, including ones that process speech and manual input, audiovisual speech input, and multibiometric input. In many important ways, these new interface designs emulate basic biological principles and systems, including the coordinated multimodal communication patterns that have evolved so impressively in humans. During multimodal communication, people's multisensory perception can achieve remarkable accuracy through fusion of different information sources.
