The 3D-LIVE project aims to develop and experiment a User Driven Mixed Reality and Immersive (Twilight) platform connected to EXPERIMEDIA facilities in order to investigate the Future Internet (FI) broadband capacity to support Real-Time immersive situations as well as evaluating both the Quality of Experience (QoE) and Quality of Services. The main objective consists to explore 3D/Media technologies and IoT in real and virtual environments in order to sense and experiment live situations. The combination of FIRE testbeds and Living Labs would enable both researchers and users to explore FI capacities to enter the Tele-Immersive application market and to establish new requirements for Internet technology and infrastructure. Combining both FI technology pull and Tele-Immersion market pull would promote and accelerate the creation and adoption of innovative sportive events based FI Services by communities of sport practitioners.The 3D-LIVE project is built around four main activities:1.\tCreate a FI Experiential Design methodology including a holistic User Experience model;2.\tDesign the architecture of the Twilight Platform;3.\tPrototype the Twilight Platform and 3D Tele-Immersive Environments;4.\tExperiment and evaluate the Twilight Platform and 3D Tele-Immersive Environments in conducting the skiing, running and golfing scenarios.The selected FIRE facilities are EXPERIMEDIA CAR and Schladming. Of particular interest is the EXPERIMEDIA advancement in new methods and algorithms for content processing targeting the efficient delivery of augmented reality to mobile devices and 3D processing for on the fly reconstruction of live events in indoor geolocalised spaces.Impacts are the FIRE facilities more useful for researching FI possibilities when integrated with Living Labs especially in extending this to IoT synchronization; New Social Interactions and Collective experiences are made possible; New Business models for the emerging Twilight zone market.
