RIDERS members you may be interested in a PhD opportunity in Participative Mixed Reality Gaming within the Cognovo project. There is much current interest in mixed or augmented reality gaming, which highlights the emergence of new patterns of behaviour associated with the use of mobile devices. These participative games with simple rules are often played by many participants and provide a platform which will allow us to examine emergent behaviours in individual and group decision making. A key research question focuses on how to design ‘local’ gaming rules that give rise to a gaming outcome that is interesting yet coherent, and also generates unpredictable or novel emergent social collective properties not anticipated in advance. Mixed reality, location-based experiences are characterised by a transition between immersive and non-immersive states, which may be characteristic of inherent multi-stability in human cognition.
