Understanding the Benefits and Drawbacks of Shape Change in Contrast or Addition to other Modalities
Anke van Oosterhout · 2019
Shape changing interfaces enable exciting new ways to interact with devices, to communicate information, meaning and affect, and provide dynamic affordance. Such interfaces are often complex and more expensive to fabricate compared to tangible, screen-based and voice interfaces. The research field has yet to explore the advantages and drawbacks of shape change in contrast to other modalities. The research outlined in this paper aims to evaluate shape changing interfaces for different purposes in contrast to interfaces that rely on tangible, screen-based or voice interaction. Shape change will be explored in the context of explainable AI to examine how it affects aspects like usability, user experience, user engagement and trust. The aim of this research is to generate an understanding about the conditions under which shape changing interfaces are beneficial and when traditional or multimodal interfaces are more appropriate.
