Social Feedback in Display Ecosystems

Public display technology (like digital signage) and private one (like smartphones) has advanced significantly in capacity, capability and spread over the past years. For the provision of information services in display technology rich settings we draw the analogy to biological ecosystems as a community of living organisms together with nonliving components of the environment, linked together through information flows, and by that acting as a global system. We identify individuals in the information society with their situational information demands and their implicit and explicit interaction styles as the living, and the plethora of display devices as the non-living part of an information ecosystem. A local interactions oriented service architecture is developed, the SAPERE pervasive service substrate. A situation aware social feedback mechanism is proposed and implemented in the SAPERE architecture, demonstrating how incentivizing local interactions can stand as a principle to attain desirable global information balance.
