The conference series HCSE (Human-Centred Software Engineering) was established four years ago in Salamanca. HCSE 2010 is the third working conference of IFIP Working Group 13.2, Methodologies for User-Centered Systems Design. The goal of HCSE is to bring together researchers and practitioners interested in strengthening the scientific foundations of user interface design, examining the re- tionship between software engineering and human-computer interaction and focusing on how to strengthen user-centered design as an essential part of software engineering processes. As a working conference, substantial time was devoted to the open and lively discussion of papers. The interest in the conference was positive in terms of submissions and partici- tion. We received 42 contributions that resulted in 10 long papers, 5 short papers and 3 poster papers. The selection was carried out carefully by the International Program Committee. The result is a set of interesting and stimulating papers that address such important issues as contextual design, user-aware systems, ubiquitous environments and usability evaluation. The final program of the conference included a keynote by Liam Bannon with the title “Approaches to Software Engineering: A Human-Centred Perspective.” This talk raised a lot of interesting questions for IFIP WG 13.2 and might have had some - pact for participants to become a member of the working group. We hope that participants considered HCSE 2010 as successful as its two p- desessors in terms of interesting discussions and new ideas for scientific co-operation.
