Fondato negli anni '90, il CRS4 è un centro di ricerca interdisciplinare che promuove lo studio, lo sviluppo e l'applicazione di soluzioni innovative a problemi provenienti da ambienti naturali, sociali e industriali. Tali sviluppi e soluzioni si basano sulla Scienza e Tecnologia dell'Informazione e sul Calcolo Digitale ad alte prestazioni. L'obiettivo principale è l'Innovazione.

La missione del Centro è quella di aiutare la Sardegna a dar vita e far crescere un tessuto di imprese hi-tech essenziali per il suo sviluppo economico e culturale.

Dal 2010 il Centro occupa circa 200 persone, tra ricercatori, tecnologi e staff di supporto, che operano in 4 settori strategici della ricerca scientifica: Biomedicina, Data Fusion, Energia e Ambiente e Società dell'Informazione. Il CRS4, inoltre, gestisce uno dei principali centri di calcolo italiani, la prima piattaforma in Italia dedicata alla genotipizzazione e al sequenziamento massivo del DNA e un laboratorio di Visual Computing allo stato dell'arte.

    Advances in networked audiovisual communication facilitate the emergence of computer-supported collaborative work (CSCW). In the COHERENT project, six leading European organisations provide complementary competencies to create a new networked holographic audio-visual platform to support real-time collaborative 3D interaction between geographically distributed teams. The display component will be based on innovative holographic techniques that can present, at natural human interaction scale, realistic animated 3D images to an unlimited number of freely moving simultaneous viewers. The design of the basic networked audiovisual components will be driven by two innovative demanding applications - a collaborative medical visualisation system and a collaborative design review system for the automotive industry - that will constitute by themselves an advancement of the state of the art in their specific domains. Both applications will provide intuitive access and interaction with shared 3D models through a sensory rich 3D user interface based on non-intrusive wireless interaction devices and offering 3D audio cues. Research will strongly concentrate on enabling technology for intuitive multi user access and interaction with complex 3D signals and objects. This project proposes to build a working high-resolution display in the one metre size range that, thanks to its human scale work area, will be ideally suited for multi-user collaborative working in true 3D. The challenge of providing the large visualisation data flow needed to drive such a device will be met using a cost-effective parallel solution based on commercial-off-the-shelf graphics and computing technology. Using GEANT, the pan-European Gigabit Research Network, the project will conduct distributed testing and validation of the system concepts for the two representative application scenarios. The research will be conducted in a 30-month schedule, to guarantee evaluation and demonstration of tangible results. Rapidly evolving advances in networked audiovisual communication technology are facilitating the emergence of computer-supported collaborative work (CSCW) systems. These systems are striving to seamlessly support collaboration between geographically distant teams for the purpose of achieving higher levels of participation, productivity, and creativity. They therefore address a major societal and economic challenge. Since visualisation is one of the most natural and intuitive ways to exchange information between humans, it has become the principal medium used in co-operative and multi-user situations. At the present time, however, state of the art collaborative real-time audiovisual systems typically rely on essentially 2D environments (traditional flat screens) to share information. For many professional applications, however, the main goal is to share the physical 3D object of common interest. These applications typically include clinical discussions among teams of medical specialists, multi-disciplinary scientific debate, design reviews between OEM's and suppliers using computer aided design (CAD), where the objects may be anatomical, molecular and product models respectively. Since these are almost exclusively very complex 3D objects, providing collaborative environments able to process, transmit and display 3D data in ways that match human perceptual abilities is therefore of primary importance and would represent a significant technology breakthrough. However, at present the only computer displays able to provide all the depth cues processed by the human brain to reconstruct a three-dimensional scene are unfortunately limited to single user configurations. Quite ironically, these limitations have led to networked solutions that facilitate remote collaboration only at the expense of the isolation of each participant from their local physical environment. In the COHERENT project, six leading European organisations in their respective fields provide complementary competencies to create a new networked holographic audio-visual platform striving to seamlessly support real-time collaborative 3D interaction between geographically distributed teams. The display component will be based on innovative holographic techniques that can present, at natural human interaction scale, realistic animated 3D images to an unlimited number of freely moving simultaneous viewers. The design of the basic networked audiovisual components will be driven by two innovative demanding applications - a collaborative medical visualisation system and a collaborative design review system for the automotive industry - that will constitute by themselves an advancement of the state of the art in their specific domains. Both applications will provide intuitive access and interaction with shared 3D models through a sensory rich 3D user interface based on non-intrusive wireless interaction and offering 3D audio cues. Research will strongly concentrate on enabling technology for intuitive multi user access and interaction with complex 3D signals and objects. The technical feasibility of the proposed holographic display solution has been recently demonstrated with the development of a ''small scale'' proof-of-concept, using white light based, 24 bit true colour, holographic 3D display. This project proposes to build on this earlier success to produce a working high-resolution display in the one metre size range that, thanks to its human scale work area, will be ideally suited for multi-user collaborative working in true 3D. The challenge of providing the large visualisation data flow needed to drive such a device will be met using a cost-effective parallel solution based on commercial-off-the-shelf graphics and computing technology. The driving applications have been chosen in two important sectors where collaborative 3D technology and networked audiovisual communication have a clear potential impact and provide a sizeable market for the future exploitation of the project results. Moreover, the need for distant teams to work together for a collaborative goal is becoming increasingly common in many industrial and social situations. Therefore, the best practice and methods opened-up by this project will have implications in other application domains. In particular, they will concern high potential, industry-driven domains such as next generation 3D-TV, electronic cinema, virtual and tele-presence and future mixed-reality-based communication services. The consortium has centred the project workplan around continuous and detailed end-user involvement in the research, development, evaluation, and validation activities. The end-users will also play an instrumental role in reaching their larger community as part of the dissemination and exploitation strategy. The research will be conducted against an ambitious, but achievable, 30-month schedule, to guarantee early delivery, evaluation, and demonstration of tangible results.
