The name Surface comes from Surface Computing, and Microsoft envisions the coffee-table machine as the first of many such devices. Surface computing uses a blend of wireless protocols, special machine-readable tags and shape recognition to seamlessly merge the real and the virtual world — an idea the Milan team refers to as "blended reality." The table can be built with a variety of wireless transceivers, including Bluetooth, Wi-Fi and (eventually) radio frequency identification (RFID) and is designed to sync instantly with any device that touches its surface.

It supports multiple touch points – Microsoft says "dozens and dozens" -- as well as multiple users simultaneously, so more than one person could be using it at once, or one person could be doing multiple tasks.

The term "surface" describes how it's used. There is no keyboard or mouse. All interactions with the computer are done via touching the surface of the computer's screen with hands or brushes, or via wireless interaction with devices such as smartphones, digital cameras or Microsoft's Zune music player. Because of the cameras, the device can also recognize physical objects; for instance credit cards or hotel "Loyalty" cards.

For instance, a user could set a digital camera down on the tabletop and wirelessly transfer pictures into folders on Surface's hard drive. Or setting a music player down would let a user drag songs from his or her home music collection directly into the player, or between two players, using a finger – or transfer mapping information for the location of a restaurant where you just made reservations through a Surface tabletop over to a smartphone just before you walk out the door.

Surface computing

  1. 1. SurfaceComputingByK.SUNIL 10L35A1202
  2. 2. What is Surface Computing?• Surface computing is a new way of working with computersthat moves beyond the traditional mouse-and-keyboardexperience.• It is a natural user interface that allows people tointeract with digital content the same way they haveinteracted with everyday items2
  3. 3. Origins 2001 2003 2004 2005 2007An Idea Inspired by Cross-Division CollaborationIn 2001, Stevie Bathiche of Microsoft Hardware and AndyWilson of Microsoft Research began brainstorming concepts for aninteractive table. Their vision was to mix the physical and virtualworlds to provide a rich, interactive experience.3
  4. 4. Origins1st prototype model named T1which is based on an IKEAtable was born. Team saw thevalue of the surfacecomputer beyond simplygaming and began to favorthose applications that tookadvantage of the uniqueability of Surface torecognize physical objectsplaced on the table.2001 2003 2004 2005 2007T1 prototype4
  5. 5. Origins 2001 2003 2004 2005 2007• Humble Beginnings on a TableIn 2004, the team grew and became the SurfaceComputing group. Surface prototypes, functionality and applicationswere continuously refined. The team built more than 85 earlyprototypes for use by software developers, hardware developers anduser researchers.5
  6. 6. • Attention turned to its form factor- Tubproto type was designed• By late 2004, the Microsoft Surfacedevelopment platform was established and attentionturned its form. A number of different experimentalprototypes were built, including the “tub” model thatwas encased in a rounded plastic shell, a desk-heightmodel with a square top and cloth-covered sides andeven a bar-height model. After extensive testing anduser research, he current look and feel of Surfacewas finalized in 2005.Origins 2001 2003 2004 2005 2007Tub Prototype
  7. 7. OriginsFrom Prototype to Product• Final structure finalised, interactivetabletop device was built thatbrings both the physical and virtualworlds into one.2001 2003 2004 2005 2007Surface computer7
  8. 8. FeaturesDirect InteractionMulti-touch contactMulti-user experienceObject recognition8
  9. 9. Multi-touch contact : Surface computing recognizes manypoints of contact simultaneously, notjust from one finger like a typicaltouch-screen, but up to dozens of itemsat once. Surface computer is optimized torecognize 52 simultaneous multitouchpoints of contact. some of the first devices withmulti-touch support are Apple’siPhone and Jeff Han’s Media Wall9
  10. 10. Gestures:10
  11. 11. Multi-User Experience: Multi-touch technology benfits the Multi-usertechnology The horizontal form factor makes it easy for severalpeople to gather around surface computers together,providing a collaborative, face-to-face computingexperience.11
  12. 12. Direct interaction:• Direct interaction means that, we caninteract with the Surface by using ourfingers.• No other input device is needed to giveinput.• This provides a natural interface effect.12
  13. 13. Object Recognition:• Object recognition is donein the surface by usingspecial bar codes calledDomino tags.• These are infraredsensitive patterns whichare read by the infraredsensing cameras insidethe surface.13

  17. 17.  Screen: A diffuser turns the Surfaces acrylic tabletop into alarge horizontal "multitouch" screen. The Surface can recognizeobjects by their shapes or by reading coded "domino" tags. Infrared: Surfaces "machine vision" operates in the near-infrared spectrum, using an LED light source aimed at the screen.When objects touch the tabletop, the light reflects back and ispicked up by multiple infrared cameras with a net resolution of1280 x 960. CPU: Surface uses many of the same components found in everyday desktopcomputers using wireless communications through WiFi and Bluetooth antennas.The underlying operating system is a modified version of Microsoft Vista. Projector: Microsofts Surface uses the same DLP light engine found inmany rear-projection HDTVs.How it works..?17
  18. 18. 18Where Surface Is Available To Us AT&T became the firstretail location to launchSurface on April 17, 2008 In June 2008 Harrah’sEntertainment launchedSurface at their Rio iBar Disneyland launched itin their Tomorrowland,Innoventions Dream Home Sheraton Hotelsintroduced Surface intothe hotel lobbies of 5it’s locations.Currently only availablefor commercial use.
  19. 19. Application Development:Microsoft Surface 2.0 Software Development Kit (SDK) is used tobuild applications for the Samsung SUR40 and Windows touch PCs. The SDK works with Visual Studio and targets the .NET Framework 4.0running on Windows 7.19
  20. 20. Applications…•Digital photo handling with finger tips.•Instantly compares while shopping.•Interaction with digital content by share, drag and dropdigital images.•Surface Restaurant.•Quickly browse through play list entries dragging favoritesong to the current track…•Easy to take complex shopping decisions.20
  21. 21. Digital photo handling with fingertips.• We can handleimagesdirectly withour finger.• Manipulatingthe images iseven morebetter thanthe realphotos.21
  22. 22. Instantly compares while shopping• We can directlycompare differentproducts just byplacing them on thesurface.• This is done usingobject recognitiontechnology.22
  23. 23. 23Browsing Menu with Surface
  24. 24. Disadvantages..• Incredibly expensive.• Currently designed only in some areas.• Need for dim lighting to avoid washing out the screen.Advantages..• Multi users- collaborative effort of users interacting.• Seamless- no wires or USB ports.• Instant download/upload of photos.• Users have more control of technology- ordering food or manipulating photos fast.• Educational- learn more info about the products you are using.24
  25. 25. ‘A computer on every desktop.’Now we say,‘Every desktop will be a computer.’Conclusion25
