Glass, Paper, Scissors: Investigating the Metaphors of the Glass Cast through Paper Prototyping

Ernesto Peña, Teresa Dobson


This article reflects on the importance of user feedback in early stages of the design process of Glass Cast. A 3-D interface, Glass Cast is intended for the visualization of knowledge networks, including parameters such as authorship, time, subject, discipline, and connections between documents in a corpus. The name Glass Cast refers to the working metaphor of the prototype, which is a cast sculpture in which the object of representation appears as negative space in a glass block. The participants in this study, graduate students and faculty in the humanities and social sciences, provided feedback on a low-fidelity paper prototype in the context of interviews. Their feedback is organized following the taxonomy of user-interface metaphors.
