This paper describes a new approach to visualization of scenarios within the use case-based engineering of functional requirements – the so-called Video Camera metaphor. The Vid...
iary models in order to bridge the semantic gap between high-level, abstract user requirements and low-level, concrete programs and to support a stepwise refinement process. This d...
We outline strategies for actuated tangible user interfaces (TUIs) to improve the study of proteins. Current protein study tools miss fundamental biology concepts because graphica...
A novel interface system for accessing geospatial data (GeoMIP) has been developed that realizes a user-centered multimodal speech/gesture interface for addressing some of the cri...
We present research leading toward an understanding of the optimal audio-visual representation for illustrating concepts for illiterate and semi-literate users of computers. In ou...
