The criteria for the award include IFIP involvement through IFIP TC13, TC13 Working Groups (WGs) or in the organization of the INTERACT conference, multiple publications at INTERACT, a significant research contribution (possibly with specific/new application domains), or being a HCI pioneer in the original meaning of the word, either in the area of HCI or in a local area (region or country) in the world.
