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.”

“The design of robust interfaces that process conversational speech is a challenging research direction largely because users' spoken language is so variable. This research explored a new dimension of speaker stylistic variation by examining whether users' speech converges systematically with the text-to-speech (TTS) heard from a software partner. To pursue this question, a study was conducted in which twenty-four 7 to 10-year-old children conversed with animated partners that embodied different TTS voices. An analysis of children's amplitude, durational features, and dialogue response latencies confirmed that they spontaneously adapt several basic acoustic-prosodic”

“ Software design is the act of determining the user's experience with a piece of software. It has nothing to do with how the code works inside, or how big or small the code is. The designer's task is to specify completely and unambiguously the user's whole experience. ”

-- David Liddle, From Bringing Design to Software, edited by Terry Winograd, 1996 ”
