GHOSTs are display surfaces made of malleable materials that can change into and retain arbitrary shapes to display output from the system or afford new actions. At the same time, GHOSTs allow users to deform, touch, or otherwise manipulate the shape of their display surface to provide input to the system. The objective of the project is to design, develop, and evaluate GHOST prototypes. The project combines disciplines focusing on (a) the hardware and software for shape change, using combinations of shape actuators and smart materials; (b) the industrial and interaction design for such interfaces, how to make them physically appealing, useful, and usable; and (c) the user experience of interacting with GHOSTs, quantifying and modelling users’ performance with and affect towards the interface.
At ID two PhD candidates worked on GHOST and it was the topic of various student projects. Matthijs Kwak explored how the design opportunities of shape-change could be opened for expert designers and students. Supported by user studies evaluating emergent interaction phenomena and patterns he developed tools that allow for a high-level design of shape-change. Brandon Yeup Hur explored how embodied approaches to interaction design can support designers in dealing with the complex challenge of designing for shape changing technologies that are not available yet. He developed a design method that departs from interaction with classical mechanical products to inspire future interactions through design frameworks and dance. Various bachelor and master students developed prototypes that explored both abstract shape-changes, addressing their aesthetics, and concrete applications.
