Youtube: Through the combining glass
Diego Martinez Plasencia, Florent Berhaut and Sriram Subramanian will present their paper on how semi transparent mirrors blend together the spaces in front and behind them. The paper investigates this further and highlights a whole new range of interactive experiences enabled by it.
In a museum, people in front of a cabinet would see the reflection of their fingers inside the cabinet overlapping the exact same point behind the glass. By directly pointing at the exhibit with their reflection, instead of pointing at them through the glass, people could easily discuss the features of the exhibits with other visitors. Pop-up windows can also show additional information about the pieces being touched.
Combining this approach with different display technologies offers interesting possibilities for interaction systems. By placing a projector on top of the cabinet, fingertips could work as little lamps to illuminate and explore dark and sensitive objects. When a hands reflection cuts through the object, the projections on visitorsí hands could be used to reveal the inside of the object, which would be visible to any user.
We also demonstrated artistic installations that combine this approach with volumetric displays. Musiciansí record loops in their digital mixers and these appear as floating above the digital mixer. Musicians could then grab these representations, to play them or tweak them with different musical effects.
