Personal clipboards for individual copy-and-paste on shared multi-user surfaces

摘要: 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 clipboards to multi-user surfaces. Personal enable individual independent operations, in the presence of multiple concurrently sharing same direct-touch interface. As common surface platforms do not distinguish touch input different users, have developed leverage complementary personalization strategies. Specifically, built a context menu clipboard based implicit user identification every touch, subareas dynamically placed surface, handheld integration devices for interaction. study, demonstrate effectiveness shared surfaces, show strategies clipboards, albeit with impacts interaction characteristics.
