50 years of research in Engineering Interactive Computing Systems: the CCL 1974 to EICS 2024 journey

This panel commemorates the 50th anniversary of the IFIP TC2 Working Conference on Command Languages (CCL) and the 30th anniversary of the workshop series on Design Specification and Verification of Interactive Systems (DSV-IS), and uses that opportunity to position EICS within the HCI community. The discussion traces the origins of the EICS conference, from the union of seminal conferences to its current status and looks forward into its (possible) future. Reflecting on its contributions to the evolution of HCI methodologies, tools, and practices, the panel highlights the conference's role and impact on shaping the engineering of interactive systems.
