This paper proposes TransformTable, an interactive digital table, whose shape can be physically and dynamically deformed. Shape transformations are mechanically and electrically actuated by wireless signals from a host computer. TransfomTable represents digital information in a physically changeable screen shape and simultaneously produces different spatial(More)
MovemenTable (MT) is an exploration of moving interactive tabletops which can physically move, gather together or depart according to people's dynamically varying interaction tasks and collaborative needs. We present the design and implementation of a set of MT prototypes and discuss a technique that allows MT to augment its visual content in order to(More)
We propose D-FLIP, a novel algorithm that dynamically displays a set of digital photos using different principles for organizing them. A variety of requirements for photo arrangements can be flexibly replaced or added through the interaction and the results are continuously and dynamically displayed. D-FLIP uses an approach based on combinatorial(More)
To allow robots and agents to serve users with less-distractive timing, the systems need to estimate the communication status of human social activity. Nonverbal information has the potential to be used to estimate communication status without recording conversational content. In this study, we prototyped a pervasive speaker estimation system and examined(More)
This study examined how gaze and speech rate affect perceptions of a speaker. Participants viewed a video recording of one of four persuasive messages delivered by a female speaker. Analysis of speech rate, gaze, and listener's sex revealed that when combined with a small amount of gaze, slow speech rate decreased trustworthiness as compared to a fast(More)
