Abstract:
Lightweight Augmented Reality eyewear will soon offer an opportunity to extend mobile Web browsing beyond the physical phone, enabling users to interactively offload parts of a page into the space around them. But developing a system that effectively supports such user-driven content offloading poses both design and technical challenges. Informed by a set of mobile Web browsing scenarios, we identify three main challenges: Expressive Selection - let users easily offload any Web page part they want; Stable Anchoring - let users seamlessly place those elements in their surroundings, not only in their field of view or in the world, but anchored to the phone as well; and Adaptable Rendering - enable changes to the layout, styling and interactive behavior of offloaded elements to optimize them for display in mid-air. We rely on these challenges to structure the space of existing design options. Using two complementary probes, we explore design options addressing these challenges and assess their feasibility and integration within the constraints of current AR eyewear and Web technologies. We discuss the strengths and weaknesses of the different options to individual challenges, as well as the trade-offs involved in addressing all challenges jointly.
