TANGerINE Grape is a collaborative knowledge sharing system that can be used through natural and tangible interfaces. The final goal is to enable users to enrich their knowledge through the attainment of information both from digital libraries and from the knowledge shared by other users involved in the same interaction session.
TANGerINE Grape is a collaborative tangible multi-user interface that allows users to perform semantic based content retrieval. Multimedia contents are organized through knowledgebase management structures (i.e. ontologies) and the interface allows a multi-user interaction with them through different input devices both in a co-located and remote environment.
TANGerINE Grape enables users to enrich their knowledge through the attainment of information both from an informative automatic system and from the knowledge shared by the other users involved: compared to a web-based interface, our system enables a collaborative face-to-face interaction together with the standard remote collaboration. Users, in fact, are allowed to interact with the system through different kind of input devices both in co-located or remote situation. In this way users enrich their knowledge even through the comparison with the other users involved in the same interaction session: they can share choices, results and comments. Face-to-face collaboration has also a ‘social’ value: co-located people involved in similar tasks improve their reciprocal personal/professional knowledge in terms of skills, culture, nature, interests and so on.
As use case we initially exploited the VIDI-Video project and then, to provide a faster response time and more advanced search possibilities, the IM3I project enhancing access to video contents by using its semantic search engine.
This project has been an important case study for the application of natural and tangible interaction research to the access to video content organized in semantic-based structures.
TANGerINE cities is a research project that investigates collaborative tangible applications. It was made within TANGerINE research project. This project is an ongoing research on TUIs (tangible user interfaces) combining previous experiences with natural vision-based gestural interaction on augmented surfaces and tabletops with the introduction of smart wireless objects and sensor fusion techniques.
Unlike passive recognized objects, common in mixed and augmented reality approaches, smart objects provide continuous data about their status through the embedded wireless sensors, while an external computer vision module tracks their position and orientation in space. Merging sensing data, the system is able to detect a richer language of gestures and manipulations both on the tabletop and in its surroundings, enabling for a more expressive interaction language across different scenarios.
Users are able to interact with the system and the objects in different contexts: the active presentation area (like the surface of the table) and the nearby area (around the table).
Presented at Frontiers of Interaction V (Rome, June 2009).
TANGerINE cities concept
TANGerINE cities let users choose and elaborate sounds characterizing today’s cities. TANGerINE cube collects sound fragments of the present and reassemble them in order to create a harmonic sounds for the future. TANGerINE cities is a mean of collective sound creation: a glimpse into the sound world of the future cities. TANGerINE cities imagines a future where technological development will have aided the reduction of metropolitan acoustic pollution, as transforming all noises into harmonic soundscape. The collaborative nature of TANGerINE table let users compare face-to-face their ideas as they forecast how noises of future cities will sound like. TANGerINE cities can use noises uploaded on the web by users who have recorded noises of their own sound worlds. Therefore TANGerINE platform provides a real tangible location within the virtual Social Networks.
