Since its inception, a core aspiration of deliberative democracy has been to enable more and better inclusion within democratic politics. In this article, we argue that deliberative democracy can achieve this aspiration only if it goes beyond verbal forms of communication and acknowledges the crucial role of non-verbal communication in expressing and exchanging arguments. The article develops a multidimensional approach to deliberative democracy by emphasizing the visual, sonic and physical dimensions of communication in public deliberation. We argue that non-verbal modes (...) of communication can contribute to public deliberation when they (1) are used as part of reason-giving processes, (2) enable the inclusion of marginalized actors in public debates and (3) induce reflection and encourage new ways of thinking about the public controversies at hand.

The cornerstone of the human-centred tradition lies in two notions: socially useful production and human machine symbiosis. However, only the latter became in focus in the successive user-centred design approaches. The paper makes a critical ‘flash-back’ to various human centred design approaches since the 1970s. In addition, it explores the sustainability challenges facing the current situation and suggests that ‘human-centredness’ should be extended to ‘human-context centred’ approach in order to recognize the challenges of the sustainability. Finally, the paper discuss the (...) possibilities to develop and use narrative and modelling simulation methods including both qualitative and quantitative tools in a combined approach to meet the challenges of sustainable development within such a human-context centred approach.
