Discrete and continuous modes of manual control are fundamentally different: buttons select or change state, while handles persistently modulate an analog parameter. User interfac...
We describe an efficient parallel algorithm for hiddensurface removal for terrain maps. The algorithm runs in Olog4 n steps on the CREW PRAM model with a work bound of On + kpolyl...
Applications for computer supported cooperative work can gain from component models and frameworks. The framework for "questionnaires", which is described in this paper,...
CSCW seems to have a persistent problem of understanding the nature of “cooperative work”. This paper argues that this problem is a direct result of not looking at the dynamic...
This document describes the core Legion object model. The model specifies the composition and functionality of Legion's core objects--those objects that cooperate to create, ...
