Direct interaction. Users can actually “grab” digital information with their hands and interact with content by touch and gesture, without the use of a mouse or keyboard.
Multi-touch contact. Surface computing recognizes many points of contact simultaneously, not just from one finger, as with a typical touch screen, but up to dozens and dozens of items at once.
Multi-user experience. The horizontal form factor makes it easy for several people to gather around surface computers together, providing a collaborative, face-to-face computing experience.
Object recognition. Users can place physical objects on the surface to trigger different types of digital responses, including the transfer of digital content.
Behind the scene it has Vista, couple of digital cameras, DLP projector and lot of advancements in touch screen.
Overall this is mind blowing stuff. If this had come from Apple, technology media would have been on fire. I wonder how will this intersect with iPhone patents?
Check this video. Amazing stuff.
