Blue Sky conference http://fet-eye.eu/bs-2014 Abstract: Virtual reality technologies are going beyond the desktop, allowing mixed-reality to be embedded in common spaces. The application of these technological advances to the creative collaborative processes, including learning, would not only allow spaces for conveying, understanding, expressing, sharing ideas, safe training and trials, but also preserving and retrieving these highly dynamic activities. This project aims at building a system for exploring, preserving and retrieving knowledge that resides in collaborative activities conducted in mixed reality settings. It is believed that such a system can represent the next step in virtual reality-based working and learning, giving access to the knowledge that is usually hidden and too fluid for being captured and re-experienced. The proposed system will be created as an online platform, based on cloud computing. It will use virtual reality in a new way to ensure high educational value for each unique learner, allowing the use of innovative methodologies based on learning by doing while keeping formation costs low.
