LRI (Laboratoire de Recherche en Informatique) is the laboratory of computer science at the Université Paris-Sud, France. The HCI group conducts fundamental research to build software systems and prototypes that explore new ideas, to validate abstract models and frameworks, and to disseminate the results through high-quality research publications

The HCI group has developed many international collaborations including: University of Toronto (Canada), Xerox PARC (USA), Rank Xerox EuroPARC (UK), University of Aarhus (Denmark), the Royal College of Art (UK). Projects are funded by French industry and/or government and the European Union (Eureka ESF project, 1990-94).

Recent projects include a collaboration with University of Aarhus funded by Hewlett-Packard, Microsoft Research and the Danish Centre for IT on new interaction techniques for graphical editing. Current projects include the IST project InterLiving on communication technologies with families and a French-government funded project on engineering for user interfaces called INDIGO.

Members of the group have been very active in the French HCI community, including founding the French annual HCI conference (Journées IHM, since 1989), the first French journal on human-computer interaction (RIHM) and the French HCI organisation, AFIHM (Association Francophone d'Interaction Homme-Machine). Members of the group are also active internationally in ACM, AMC/SIGCHI and in IFIP working groups. The HCI group's expertise in engineering of user interfaces, advanced interaction techniques and groupware and CSCW is particularly suited to the challenges of end-user programming. The HCI group has been working on computer-supported co-operative work for over a decade, installed the first French media space in 1993 (still in use today), and has developed original interfaces using gestures, sound, and video.
