Surface Computing

  1. 1. SURFACE COMPUTING
  2. 2. What is surface computing?A form of computing that offers “a natural way ofinteracting with information,” rather than the“traditional user interface”Surface computing typically includes four keyattributes: Direct Interaction Multi–Touch Multi–User Object Recognition
  3. 3. DIRECT INTERACTIONThe ability to "grab"digital information withhands - interacting withtouch/ gesture, not with amouse or keyboard.
  4. 4. MULTI – TOUCHThe ability to recognizemultiple points of contactat the same time, not justone (Ex. One finger, likewith most touch screens),but dozens.
  5. 5. MULTI – USERThe Surface’s screen ishorizontal , allowing manypeople to come togetheraround It and experience a“collaborative, face–to–face computingexperience”
  6. 6. OBJECT RECOGNITIONPhysical objects can beplaced on the Surface’sscreen to “trigger differenttypes of digital responses”(Ex. cell phones, cameras,& glasses of wine)
  7. 7. Developments done till now.Types1.Microsoft Surface2. Laser Touch (Microsoft)3. Gesture Tek4. Perceptive Pixel5. Diamond Touch (Mitsubishi)6. Smart Table7. Catchyoo8. Reactrix9. Sensacell
  8. 8. Microsoft Surface The Surface is not a touch-sensitive screen device…The screen itself is not electronic The Surface uses multiple infrared cameras beneath thescreen/table top to sense objects, physical touch, etc The Surface “recognizes objects based on shape or byusingdomino-style identification (domino tags) on the bottomof the objects ” This information is processed and displayed using“ rear projection ”
  9. 9. Working of Microsoft Surface
  10. 10. Working of Microsoft SurfaceScreen: Diffuser -> ”multitouch" screen. Can process multipleinputs and recognize objects by their shapes or coded "domino"tags.Infrared: The ”machine vision" is aimed at the screen. Once anobject touches the tabletop -> the light reflects back and ispicked up by infrared cameras.CPU: Uses similar components as current desktop computers ->Core 2 Duo processor, 2GB of RAM and a 256MB graphics card.Wireless communication -> Wi-Fi and Bluetooth antennas (future-> RFID). Operating system -> modified version of MicrosoftVista.Projector: Uses a DLP light engine ( rear-projection HDTVs).
  11. 11. Where is it used?seminarsEasy data transferAirportsShopping malls,hotels,etc…Work placetransportation
  12. 12. R&D Research work is going on several top universitieslike MIT (Massachusetts Institute of technology)with a innovation named SIXTH SENSE. This is anapplication of surface computing. Research on building user defined gestures thatare used in surface computing that make thegraphical representation more intuitive…
  13. 13. ADVANTAGESData representation/transfer is moreintuitiveUser friendlyNo use of input/output devices like mousekeyboard etc . . .Easily portable . . .
  14. 14. Microsoft Surface
  15. 15. ConclusionSurface takes existing technology andpresents it in a new way. It isnt simplyatouch screen, but more of a touch-grabmove-slide-resize and place objects ontop of screen, and this opens up newpossibilities that werent there before
