A Novel Multimedia Interactive System for Public Show and Presentations

Holographic interactivity is nowadays a promising research topic within HCI field, mainly due to recent technological improvements. Moreover, low-cost off-the shelf components are widely availables, with respect to the last century situation for traditional human-machine interaction paradigms. The way of displaying information and data communication are now much more robust and solid than in the past, allowing better user experiences (Ux) than before in terms of presence and immersion. The paper presents a novel interaction system based on holographic and multi-touch technologies well suited for shows and interactive talks. The performer/presenter operates behind a vertical touch enabled transparent holographic panel where multimedia contents are projected and directly manipulated. This type of communication is much more cogent and immersive than any other, since both the presenter and the public interact facing each other with the possibility of focusing their attention on the same interspersed interactive elements. Furthermore, the system relies on a web based cross-platform framework allowing both proximal and remote interaction and visualization on smartphones, tablets and internet enabled devices in general. Preliminary interviews have underlined the goodness of this new interaction paradigm suggesting that this could be a strong base of a much larger platform for many and different uses.
