Disentangling participation through time and interaction spaces–the case of IT design for energy demand management

Participatory Design has recently seen growing interest in developing critical forms of reflexivity able to disentangle the complexity of participatory ensembles. This article makes a methodological contribution to this endeavour. Drawing on socio-cognitive analyses of collaborative design, it proposes the frame of ‘interaction spaces’ as a scaffolding tool for conducting retrospective analyses of participatory design processes. The paper uses the ‘interaction spaces’ frame to analyse the three years of collaborative activities of the CIVIS Project. Through a longitudinal and multi-dimensional account of participatory dynamics involved in the designing, prototyping and testing of an IT platform for home energy management, the frame evidences how participatory configurations evolve over time; it makes clearer the characteristics of participation as partial and overtaken; and it identifies moments of cross-participation as potential basis for the boundary-spanning of design issues.
