As an input device, fabric holds potential benefits for three dimensional (3D) interaction in the domain of surface design, which includes designing objects from clothing to metalwork. To investigate these benefits, we conducted an exploratory study of different users' natural interactions with fabric. During this study, we instructed users to communicate various shapes and surfaces of varying complexity. A prevailing way of communicating shapes proved to be an in-the-air sketch metaphor. Based on this result, we proposed and implemented a system supporting three in-the-air sketch-based input devices: a point, a flexible curve, and a flexible surface. A preliminary feasibility study found that users successfully sketched objects and scenes despite the influence of tracking issues, suggesting lessons learned and relevant constraints for such systems in future work.

Storyboards offer designers a way to illustrate a narrative. Their creation can be enabled by tools supporting sketching or widget collections. As designers often incorporate previous ideas, we contribute the notion of blending the reappropriation of artifacts and their design tradeoffs with storyboarding. We present PIC-UP, a storyboarding tool supporting reappropriation, and report on two studies - a long-term investigation with novices and interviews with experts. We discuss how it may support design thinking, tailor to different expertise levels, facilitate reappropriation during storyboarding, and assist with communication. Copyright 2011 ACM.
Artifacts can be used to inspire, guide, and create new designs. As approaches to design can range from focusing on inspiration to formalized reasoning, we seek to create and study artifacts that combine the use of im...

interaction for desktop games is mostly limited to keyboard and mouse input. We are investigating the benefits of adding body-based interaction to complement keyboard and mouse interaction in desktop gaming. We present a proof-of-concept implementation of body-based navigation for the game World of Warcraft, and a formative evaluation to test the feasibility of this kind of interaction. Our observations provide evidence that body-based interaction in addition to keyboard and mouse can help players perform more tasks at the same time and can be especially attractive and helpful to new players. Our study also revealed design consideration for this type of interaction.
