We describe MAUI, a user interface design tool that is based on a matrix algebra model of interaction. MAUI can be used to build and analyse designs for interactive systems, such as handheld devices. This paper describes MAUI, its advantages and underlying mathematical approach. MAUI is implemented in Java and XML, which allows flexible integration with other parts of the design life cycle, suc...

LATEX by Adam Jobson For a family of graphs F closed under subgraphs, and a graph G from F , define a game (G,F) played by Builder and Painter. The game begins with Builder presenting an edge and Painter coloring the edge red or blue. On each turn thereafter, Builder adds another edge to the red-blue colored graph present (adding vertices if needed), so that the new graph, viewed uncolored, is ...

Online Questionnaire Builder (OQB) is web-based survey software that provides complete set of tools for users to conduct the overall survey process from questionnaire design and distribution to the presentation of the survey results. This paper delivers the implementation a comprehensive set of guidelines for the design of online questionnaires via our survey software. The guidelines are drawn ...

When graph Ramsey theory is viewed as a game, “Painter” 2-colors the edges of a graph presented by “Builder”. Builder wins if every coloring has a monochromatic copy of a fixed graph G. In the on-line version, iteratively, Builder presents one edge and Painter must color it. Builder must keep the presented graph in a class H. Builder wins the game (G,H) if a monochromatic copy of G can be force...
