MoLIC, a modeling language for designing interaction as a metaphor of conversation, was proposed to allow designers to build a blueprint of all interaction that may take place when the application is used. With the tool presented on this paper, we are willing to address some questions regarding the use of MoLIC when designing interactive applications, while it might serve to raise the critical mass onto Semiotic Engineering among HCI practitioners and researchers. It is composed of a diagram builder, with syntactic verification based on the MoLIC language. It also allows designers to bind goals with interaction paths and helps to compare different design decisions. Categories and Subject Descriptors
