Abstract. 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 extensively signified and encoded into technology, whether they know it or not. Users are deeply affected by the designers' F2F sociability models. Two qualitative methods of analysis are used to reveal the richness of interpretive and communicative processes in which online communities are involved, and the interplay of designers' and users' signs at interaction time.
Abstract. 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 potential social effects, springing from user-system interaction, as well from user-user interaction (through the system). The paper illustrates how Manas can lead designers to reflect upon both the design problem and its proposed solution(s), which allows them to make more conscious decisions. Increased knowledge and awareness should then enhance the quality of CoSys design.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
