Recent years have witnessed an increasing shift in interest from single user multimedia/multimodal interfaces towards support for interaction among groups of people working closely together, e.g. during meetings or problem solving sessions. However, the introduction of technology to support collaborative practices has not been devoid of problems. It is not uncommon that technology meant to support collaboration may introduce disruptions and reduce group effectiveness. Human-centered multimedia and multimodal approaches hold a promise of providing substantially enhanced user experiences by focusing attention on human perceptual and motor capabilities, and on actual user practices. In this paper we examine the problem of providing effective support for collaboration, focusing on the role of human-centered approaches that take advantage of multimodality and multimedia. We show illustrative examples that demonstrate human-centered multimodal and multimedia solutions that provide mechanisms for dealing with the intrinsic complexity of human-human interaction support.

Oviatt, Sharon, Lunsford, Rebecca and Coulston, Rachel (2005): Individual differences in multimodal integration patterns: what are they and why do they exist?. In: Proceedings of ACM CHI 2005 Conference on Human Factors in Computing Systems 2005. pp. 241-249. Available online

Techniques for information fusion are at the heart of multimodal system design. To develop new user-adaptive approaches for multimodal fusion, the present research investigated the stability and underlying cause of major individual differences that have been documented between users in their multimodal integration pattern. Longitudinal data were collected from 25 adults as they interacted with a map system over six weeks. Analyses of 1,100 multimodal constructions revealed that everyone had a dominant integration pattern, either simultaneous or sequential, which was 95-96% consistent and remained stable over time. In addition, coherent behavioral and linguistic differences were identified between these two groups. Whereas performance speed was comparable, sequential integrators made only half as many errors and excelled during new or complex tasks. Sequential integrators also had more precise articulation (e.g., fewer disfluencies), although their speech rate was no slower. Finally, sequential integrators more often adopted terse and direct command-style language, with a smaller and less varied vocabulary, which appeared focused on achieving error-free communication. These distinct interaction patterns are interpreted as deriving from fundamental differences in reflective-impulsive cognitive style. Implications of these findings are discussed for the design of adaptive multimodal systems with substantially improved performance characteristics.

I'm an enemy of what I call 'computer theology.' There's a class conflict out there. There's a techno-elite that lives in a different world.
