| This research investigates new interactions that support the transition from desktop computing beyond Ubiquitous Computing. It focuses on an emerging technology, flexible, paper-like displays, and examines the potential interactions that can be accomplished using this new medium. It provides a conceptual framework of interactions that adequately combines the digital properties of the desktop computer and the physical affordances of a paper-like device. To do this, it develops PaperWindows, a prototype windowing environment that simulates the use of digital paper. By projecting windows on physical paper, PaperWindows allows us to digitally utilize the physical shape of paper. By sensing the users interactions with real paper using computer vision, PaperWindows allows the use of paper as an input device.; Bridging the electronic world with the physical presents new and interesting design challenges. The interaction model of the desktop computer is largely based on the use of a mouse and keyboard. Paper, as an input device, is fundamentally different and more complex. Paper is hands-on; it can be bent, folded, flipped, or even stacked. Given these affordances, the goal of this research is to define an explicit set of interactions that translates the Graphical User Interface into the physical world, thereby minimizing the interaction asymmetry between desktop computer and the physical world of the user. |
