3D Presentations from the Future

I have been using Prezi.com for over a year now and it really changed the way I create my presentations. But the concept and technology the video I just discovered on New Scientist shows will certainly lead to major improvements regarding the experience of presenting and listening to presentations.

The LightSpace prototype projects slides, documents, photographs or video onto any surface, from a table to a door. Presenters can then touch and literally pick up a virtual item from a display and carry it across the room as a spot of light in the palm of their hand.

To perform commands – “play video”, for example – you move your hand along a projected light beam that acts as the central control. Holding your hand in the right position on the menu for a few seconds activates the function.
