Technology Overview

CARLSBAD, Calif. — May 29, 2007 — Picture a surface that can recognize physical objects from a paintbrush to a cell phone and allows hands-on, direct control of content such as photos, music and maps. Today at the Wall Street Journal's D: All Things Digital conference, Microsoft Corp. CEO Steve Ballmer will unveil Microsoft Surface™, the first in a new category of surface computing products from Microsoft that breaks down traditional barriers between people and technology. Surface turns an ordinary tabletop into a vibrant, dynamic surface that provides effortless interaction with all forms of digital content through natural gestures, touch and physical objects. Beginning at the end of this year, consumers will be able to interact with Surface in hotels, retail establishments, restaurants and public entertainment venues.

The intuitive user interface works without a traditional mouse or keyboard, allowing people to interact with content and information on their own or collaboratively with their friends and families, just like in the real world. Surface is a 30-inch display in a table-like form factor that small groups can use at the same time. From digital finger painting to a virtual concierge, Surface brings natural interaction to the digital world in a new and exciting way. (Microsoft Press, May 2007)

Surface computing is the term for the use of a specialized computer GUI in which traditional GUI elements are replaced by intuitive, everyday objects. Instead of a keyboard and mouse, the user interacts directly with a touch-sensitive screen. It has been said that this more closely replicates the familiar hands-on experience of everyday object manipulation.

Recent minor innovations in the surface computing field are attributed to Apple, Inc and to Microsoft Corporation. Apple had demonstrated surface computing interfaces intended for professional use since 2006, with no expected product release date. Microsoft unveiled plans for the Microsoft Surface in May 2007. The Microsoft Surface seems to be closer to production, with devices intended for consumer use at large establishments such as hotels and casinos. Much earlier work in this area was done at the University of Toronto, Alias Research, and MIT. Finally, there is Linux surface computing software as well, called Linux MPX.

Surface computing is slowly starting to catch on and is starting to be used in real world applications. Here is just a sample of what surface computing technologies have been used.
