Cost reduction and simplification of digital technologies. Personalisation and interactivity of viewing experiences in DCH, including the use of social media. New types of User Experiences (UX) with DCH that arise from the current ‘hardware and software revolution’ in the realms of VR/AR; interface selection (e.g. Augmented Reality, holograms) to allow seamless blending of on-site and on-line dimensions. Visualisation techniques and their combination in different contexts, drawing on the state of the art in technology and standards e.g. for Interactive Video (IV); Immersive VR (IVR); Augmented Reality (AR); 3D Real-time Editors (game-engines), Ultra High and Giga-Pixel Panoramas; infinite zooming images; VR Wearables and Gesture Recognition Interfaces. inter-disciplinary collaborative research to establish paradigms in socio-economic areas of DCH impact e.g. tourism, education, employment, economic growth. Crowdsourcing, co-creation and Citizen Science. using innovative social platforms to exchange user experiences and support. multidisciplinary approaches.
