This paper presents Manas, a Semiotic Engineering epistemic tool for the design of collaborative systems (CoSys) whose aim is to expand the designers' knowledge and awareness of their influence on groups and group dynamics. Manas has been developed to help designers represent their conception of computer-mediated communication and reflect upon some of its(More)
This paper discusses how semiotic engineering can support the formulation of problems and solutions involved in handling face-to-face (F2F) sociability models in computer-mediated communication (CMC). Based on a case study where a group of users migrated through different types of CMC systems, we show that the designer's model of F2F sociability is(More)
This paper presents MArq-G*, a semiotic engineering epistemic tool for the design of multi-user applications that leverages the designers' knowledge about the influence such applications may have on group dynamics and development. More precisely, MArq-G* is a conceptual architecture model for multi-user application design-support tools. It has been devised(More)
