Interaction Design Research of SMA motion display

We propose a shape memory alloy motion display (SMD), a novel piece of display equipment taking advantage of the existence of an actual object. Then, we introduce an interactive art work plant based onSMD technology. SMD does not display images with a combination of changes in light as in visual displays, instead the elements corresponding to light dots in visual displays are replaced by objects (actuators). We do not aim to display high density information as is done with images, but realize abstract expressions with physical movements and changes in shape. We are working on devices that give visual expressions and a feeling of creature-like existence from soft, creature-like movements. Applications include interactive walls as Digital Public Art [1], digital signage using visual expressions, Ambient Displays, and the moving dolls in theme parks combining 3D structure impossible with images and robotics.
