Abstract

Clipboards are omnipresent on today's personal computing platforms. They provide copy-and-paste functionalities that let users easily reorganize information and quickly transfer data across applications. In this work, we introduce personal clipboards to multi-user surfaces. Personal clipboards enable individual and independent copy-and-paste operations, in the presence of multiple users concurrently sharing the same direct-touch interface. As common surface computing platforms do not distinguish touch input of different users, we have developed clipboards that leverage complementary personalization strategies. Specifically, we have built a context menu clipboard based on implicit user identification of every touch, a clipboard based on personal subareas dynamically placed on the surface, and a handheld clipboard based on integration of personal devices for surface interaction. In a user study, we demonstrate the effectiveness of personal clipboards for shared surfaces, and show that different personalization strategies enable clipboards, albeit with different impacts on interaction characteristics.
