TransformTable: A self-actuated shape-changing digital table

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 arrangements of users around the table. This provides visual information while changing the physical workspace to allow users to effectively handle their tasks. We implemented the first TransformTable prototype that can deform from/into one of three typical shapes: round, square, or rectangular. We also discuss implementation methods and further application designs and scenarios. A preliminary study shows fundamental and potential social impacts of the table transformation on users' subjective views in a group conversation.
