Paper Abstract
"In recent years, shape change interfaces have been the focus of attention, where novel interaction techniques and application possibilities have been explored through the incorporation of shape change into static objects. In this paper, we focus on the interaction with shape-changing vertical surfaces. Existing work on vertical plane interaction is mainly concerned with visual representation using projection mapping or shape change to present interaction results. We believe that the reason for the limitation of the interaction method is that the vertical surface, such as the wall and the door, is inherently fixed. In this paper, we propose a shape-changing vertical surface that goes beyond mere 2D interaction space, which we call DeforVerFace. DeforVerFace consists of a set of linear deformable elements and modules for sensing the nearby environment. In this paper, we design and implement DeforVerFace and present a user study aimed at understanding the possibilities of a shape-changing vertical surface in our everyday building environment."
