Beyond the Desktop: a New Look at the Pad Metaphor for Information Organization
Beyond the Desktop: A new look at the Pad metaphor for Information Organization By Isaac Fehr Abstract Digital User interface design is currently dominated by the windows metaphor. However, alternatives for this metaphor, as the core of large user interfaces have been proposed in the history of Human-computer interaction and thoroughly explored. One of these is the Pad metaphor, which has spawned many examples such as Pad++. While the the Pad metaphor, implemented as zoomable user interfaces, has shown some serious drawbacks as the basis for an operating system, and limited success outside of image-based environments, literature has pointed to an opportunity for innovation in other domains. In this study, we apply the the design and interactions of a ZUI to Wikipedia, a platform consisting mostly of lengthy, linear, hypertext-based documents. We utilize a human centered design approach, and create an alternative, ZUI-based interface for Wikipedia, and observe the use by real users using mixed methods. These methods include qualitative user research, as well as a novel paradigm used to measure a user’s comprehension of the structure of a document. We validate some assumptions about the strengths of ZUIs in a new domain, and look forward to future research questions and methods. Introduction and Background Windows-based user interfaces have dominated the market of multipurpose, screen-based computers since the introduction of the first windowed system in the Stanford oN-Line System (NLS)[3]. From Desktop computers to smartphones, most popular operating systems are based upon at least the window and icon aspects of the WIMP (Window, Icon, Menu, Pointer) paradigm.
