  3. 3. What is Microsoft Surface? Project began in 2001 Introduced in 2007 A surface computing platform from Microsoft. “Microsoft Surface represents a fundamental change in the way we interact with digital content. With Surface, we can actually grab data with our hands, and move information between objects with natural gestures and touch. Surface features a 30-inch tabletop display whose unique abilities allow for several people to work independently or simultaneously. All without using a mouse or a keyboard.”
  4. 4. History ∗ In 2001, Stevie Bathiche of Microsoft Hardware and Andy Wilson of Microsoft Research began working together on various projects that took advantage of their complementary expertise in the areas of hardware and software. In one of their regular brainstorm sessions, they started talking about an idea for an interactive table that could understand the manipulation of physical pieces and at the same time practical for everyone to use. ∗ In 9th October 2001, a virtual team was formed to fully pursue bringing the idea to the next stage of development; Bathiche and Wilson were key members of the team.
  5. 5. ∗ In early 2003, the virtual team expanded, and within a month, through constant discussion and brainstorming, the first humble prototype was born and nicknamed T1. The model was based on an IKEA table with a hole cut in the top and a sheet of architect vellum used as a diffuser. The evolution of Surface had begun. A variety of early applications were also built, including pinball, a photo browser and a video puzzle. “T1 Prototype”∗ By late 2004, a number of different experimental prototypes were built including “the tub” model, which was encased in a rounded plastic shell, a desk-height model with a square top and cloth- covered sides, and even a bar-height model that could be used while standing. After extensive testing and user research, the final hardware design (seen today) was finalized in 2005.∗
  6. 6. Key attributesA form of computing that offers “a natural way ofinteracting with information,” rather than the“traditional user interface.”Direct Interaction: T ability to "grab" digital heinformation with hands - interacting withtouch/gesture, not with a mouse or keyboard.M ulti–Touch: T ability to recognize multiple points heof contact at the same time, not just one (E one x.finger, like with most touch screens), but dozens.M ulti–User: T Surface’s screen is horizontal, heallowing many people to come together around itand experience a “collaborative, face–to–facecomputing experience”.Object R ecognition: Physical objects can be placedon the Surface’s screen to “trigger different types ofdigital responses” (E cell phones, cameras, & x. glasses
  7. 7. How is the Surface used?•W ireless! Transfer pictures from camera to Surface andcell phone. “Drag and drop virtual content to physicalobjects.”• Digital interactive painting• At a phone store? Place cell phone on the Surface andget information, compare different phones, select serviceplan, accessories, and pay at table!• At a restaurant? View menu, order drinks and meal atyour table! It’s a durable surface you can eat off of(withstands spills, etc.). Need separate checks? Split billat and pay at table.• P games and use the Internet. lay•Watch television•Jukebox! Browse music, make play lists.•Billboard for advertising•Maps
  8. 8. How does it work?• T Surface is not a touch-sensitive screen device… T screen itself is not electronic. he he• T Surface uses multiple infrared cameras beneath the screen/ he table top to sense objects, physicaltouch, etc.• T Surface “recognizes objects based on shape or by using domino-style identification (domino tags) heon the bottom of the objects.”• T information is processed and displayed using “rear projection”. his (1) Screen: Diffuser -> ”multitouch" screen. Can process multiple inputs and recognize objects by their shapes or coded "domino" tags. (2) Infrared: The ”machine vision" is aimed at the screen. Once an object touches the tabletop -> the light reflects back and is picked up by infrared cameras. (3) CP Uses similar components as current desktop U: computers -> Core 2 Duo processor, 2GB of RAM and a 256M graphics card. W B ireless communication -> W i iF and Bluetooth antennas (future -> RF ID). Operating system -> modified version of M icrosoft Vista. (4) Projector: Uses a DL light engine ( rear-projection P H Vs). DT
  9. 9. FTIR: The DIY versionWhat if you don’t want it cost $10,000 • Fourier Transform Infrared Spectroscopy • Embed IR LEDs in the plexiglass • Things touching the surface of the screen scatter IR light towards the camera below
  10. 10. What’s on the Surface• Figuring out how to identify objects, grab their data, and correctly track the on the surface is a very difficult challenge in surface computing. • Make the user tell you what something is when they place it • Create a place for the user to put something and track it from there • Tag objects, identify them at runtime and then follow the tag rather than the object • Microsoft is currently working on technology to match RFID tags with physical objects based on when the tag is read and what’s placed on the surface
  11. 11. Hardware &software specification∗ Optimized for 52 simultaneous inputs 4 people with all 10 fingers plus 12 objects∗ The software platform runs on a custom version of Windows Vista.∗ Wired Ethernet 10/100,∗ Wireless 802.11 b/g,∗ Bluetooth 2.0 connectivity.∗ Intel Core Quad Xeon @ 2.66GHz∗ 4GB DDR2-1066 RAM∗ 1TB 7200RPM Hard Drive∗ It has a custom motherboard form factor about the size of two ATX motherboards.∗ Surface applications are written using either Windows Presentation Foundation or Microsoft XNA technology.∗ 5 video infrared cameras
  12. 12. Applications1 Water∗Water is used as an "attract mode" forthe Surface desktop, and it is certainlyattractive.∗A unique feature that comespreinstalled with Surface is the pondeffect "Attract" application. Simply, it isa "picture" of water with leaves androcks within it.∗By touching the screen, you cancreate ripples in the water just like youwere putting your hand into a realstream∗Additionally, the pressure of touchalters the size of the ripple created,and objects placed into the watercreate a barrier that ripples bounce off,just as they would in real life
  13. 13. 2.Music∗The Music application workslike a virtual jukebox,displaying music arranged byalbum and allowing the userto flip over albums, selectsongs, and drag them to the"Now Playing" section. Inaddition to playing music thatis already stored on the u itshard drive, Music can alsotransfer songs from portablemusic players
  14. 14. 3.Photos∗Sharing photos is a much moreunrestricted activity. Photos arearranged into albums that look likepiles. Tapping the pile once spreadsit around the screen and from thereuser can drag, rotate, and resize theimages. Since Surface can detectmany touches at the same time,multiple people can sort and resizepictures.
  15. 15. Who’ s using the Surface today?• Currently only commercially available and being used in the retail,hospitality, automotive, banking and healthcare industries.• Current customers are AT T T obile, the Rio All Suite H & , -M otel &Casino in L Vegas, Sheraton H as otels, Disney Innovations H ouse inCalifornia, H otel 1000 in Seattle, Harrah’s Entertainment, andStarwood H otels and Resorts W orldwide.
  16. 16. Advantages∗ Large surface area to view different windows and applications.∗ Data Manipulation - Selecting, moving, rotating and resizing (manipulating objects on the screen is similar to manipulating them in the manual world).∗ Quick and easy to use.∗ More Than One User –Several people can orient themselves on different sides of the surface to interact with an application simultaneously (Max 52 points of touch).∗ Objects Recognition - Increased functionality aiding user in speed and ease of use
  17. 17. Disadvantages∗ Incredibly expensive and not Portable Currently designed only in some areas.∗ Loss of Privacy - Open for many to view. Tailored to high end clients.
  18. 18. Surface computing-In future∗ Computer scientists hope to incorporate this kind of technology in peoples’ daily lives… Future goals are to surround people with intelligent surfaces-look up recipes on kitchen counter or table, control TV with coffee table, etc As form factors continue to evolve, surface computing will be in any number of environments— Schools ,businesses, homes and many more Environments.
  19. 19. Conclusion Microsoft Surface is the future of computers. Surface Computing brings to life a whole new way to interact with information that engages the senses, improves collaboration and empowers consumers. It takes existing technology and presents it in a new way. It isnt simply a touch screen, but more of a touch-grab-move-slide-resize-and-place-objects-on-top-of- screen and this opens up new possibilities that werent there before. By utilizing the best combination of connected software, services and hardware developing surface computing products that push computing boundaries, deliver new experiences that break down barriers between users and technology. ‘A computer on every desktop’ Now we say ‘Every desktop will be a computer’
