Multimodal Integration - A Statistical View
نویسندگان
چکیده
This paper presents a statistical approach to developing multimodal recognition systems and, in particular, to integrating the posterior probabilities of parallel input signals involved in the multimodal system. We first identify the primary factors that influence multimodal recognition performance by evaluating the multimodal recognition probabilities. We then develop two techniques, an estimate approach and a learning approach, which are designed to optimize accurate recognition during the multimodal integration process. We evaluate these methods using Quickset, a speech/gesture multimodal system, and report evaluation results based on an empirical corpus collected with Quickset. From an architectural perspective, the integration technique presented here offers enhanced robustness. It also is premised on more realistic assumptions than previous multimodal systems using semantic fusion. From a methodological standpoint, the evaluation techniques that we describe provide a valuable tool for evaluating multimodal systems.

Achieving Multimodal Cohesion during Intercultural Conversations
How do English as a lingua franca (ELF) speakers achieve multimodal cohesion on the basis of their specific interests and cultural backgrounds? From a dialogic and collaborative view of communication, this study focuses on how verbal and nonverbal modes cohere together during intercultural conversations. The data include approximately 160-minute transcribed video recordings of ELF interactions ...

متن کاملHuman 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, s...
متن کاملMultimodal Integration A Biological View
We present a novel methodology for building highly integrated multimodal systems. Our approach is motivated by current cognitive and behavioral theories of sensory perception in animals and humans. We argue that perceptual integration in multimodal systems needs to happen at the lowest levels of the individual perceptual processes. Rather than treating each modality as a separately processed, i...
