Clarisse Sieckenius de Souza is a professor at the Department of Informatics of Pontifical Catholic University of Rio de Janeiro (PUC-Rio). With a Ph.D. in applied linguistics, she started in computer science doing research in natural language processing and text generation. She gradually moved from artificial intelligence into HCI, switching her interdisciplinary base from linguistics to semiotics. She is the founder and principle investigator of the Semiotic Engineering Research Group (SERG) at PUC-Rio, which produced the most comprehensive semiotic account of HCI in Informatics to date.Carla Faria Leitao is a senior researcher of SERG at PUC-Rio. She has a Ph.D. in clinical psychology and has been drawn to informatics and HCI by the subjective aspects of computer artifacts exposed and explored by semiotic engineering. With a special interest in how qualitative methods can be used outside the social and human sciences, she has been leading methodological research in SERG since 2002.

• Introduction.- Essence of Semiotic Engineering.- Semiotic Engineering Methods.- Case Study with Audacity.- Lessons Learned with Semiotic Engineering Methods.- The Near Future of Semiotic Engineering.
