Its Microsoft Research old habit to show off some imaginary cool stuff that may or may not actually happen. Director of Microsoft Applied Sciences Steven "Stevie B" Bathiche showed off a variety of interesting interfaces that respond to gesture movements that take you well beyond the touchscreen, by using a camera and retro-reflective sash to detect hand position and responding. Later things goes to a flat lens called a wedge that can enable holographic-like imagery. Overall the concept lets you feel the real magical power to command the things floating around you. If it become a reality then development can lead us to hyper-real artificial world in future where every individual will be able to build own worlds according to desires.
