Crowd-Computer Interaction, a Topic in Need of a Model

Abstract. Crowd-Computer Interaction -CCI -is a form of human-computer interaction -HCI -in which single actions from many individuals are aggregated to produce a different result that would not be achievable otherwise for one individual alone. As a research topic several questions remain open regarding CCI, for example, to what extent the principles and heuristics of interactions design under the paradigm of one-user-one-interface are applicable to crowds interacting with a network of interfaces? If a system is usable for individuals, will it be usable for crowds? Should designs be centered on the individual or on the crowd? A model of how crowds interact with computers is needed to start finding answers, that need is discussed in this paper along with some research proposals to develop that model
