  1. 1. Presented By:- Vivek Kumar Roll No:-1122310046 B-TECH (6th sem) Submitted to:- MIS Shalini Gupta (CSE Department)
  2. 2. CONTENTS  Introduction  Origin  Revolution in user interface  Key challenges  Surface interface  Surface computer  Hardware specification  Technology behind surface computing  How surface works?  Advantage/Disadvantage  In future  Conclusion
  3. 3. WELCOME TO FUTURESURFACE COMPUTER
  4. 4. CUI ( PC)-1985 GUI (INTERNET)- 1990 NUI (SURFACE TABLE)-2001 REVOLUTION IN USER INTERFACE
  5. 5.  BY-STEVIE BATHICHE (MICROSOFT HARDWARE) AND ANDY WITSON (MICROSOFT RESEARCH  VISION TO MIX THE PHYSICAL AND VIRTUAL WORLD 200720042001 AN IDEA INSPIRED BY CROSS DIVISION COLLABORATION
  6. 6.  SURFACE COMPUTING GROUP DEVELOPED  THE TEAM BUILT 85 EARLY PROTOTYPE FOR USE 2001 HUMAN BEGINNING ON A TABLE 20072004
  7. 7.  TODAY  MICROSOFT SURFACE IS DEVELOPED  30 INCH DIOGONAL DISPLAY  TRANSLUCENT SURFACE  PEOPLE ENGAGE WITH SURFACE USING HAND GESTURE FROM PROTOTYPE TO PRODUCT 2001 2004 2007
  8. 8. A KEY CHALLENGES TRADITIONAL COMPUTER USES KEYBOARD AND MOUSE BASED WIDGET IS NO LONGER PREFERABLE
  9. 9. SURFACE INTERFACE FOUR MAJOR COMPONENT DIRECT INTERACTION MULTI-USER EXPEREINCE OBJECT RECOGNITION MULTI- TOUCH CONTACT
  10. 10. MULTI-USER EXPERIENCE  A SINGLE TOUCH SCREEN CAN SUPPORT MORE THAN ONE USER  EACH USER CAN INTERRACT INDEPENDENTLY WITH THE SURFACE
  11. 11. MULTI-TOUCH CONTACT  ORDINARY TOUCH PROVIDE ONLY SINGLE TOUCH SENSING  IN SURFACE MORETHAN ONE TOUCH CAN SED
  12. 12.  IT MEANS WE CAN INTERACT WITH THE SURFACE BY USING FINGER  THIS PROVIDES A NATURAL INTERFACE EFFECT (NUI) DIRECT-RECOGNITION
  13. 13. OBJECT RECOGNITION  BAR TAG (DOMINO TAGS)  INFRARED SENSITIVE PATTERNS
  14. 14. 1. Screen:- A large horizontal “ Multi-touch ” screen, The Surface can recognize objects by reading coded “domino” tags. 2. Infrared:- Surface uses a 850-nm light source. 3. CPU:- Core2Duo processors 2GB of RAM 256MB graphics card. 4. Projector:- The Surface uses DLP light engine found in many rear projection HDTV's.
  15. 15. RESISTIVE TOUCHSCREEN RESISTIVETOUCHSCREEN USER PROCESS DOWN CONTACT IS MADE UNIFORM VOLTAGE ON FIRST SREEN FOR X SAME ON SECOND SCREEN FOR Y CONTROLLER DECIDES POSITION OF TOUCH
  16. 16. CAPACITIVE TOUCHSCREEN 1 • 4 ELOCTRODE AT 4 CORNER 2 • A HUMAN BODY IS AN ELECTRIC CONDUCTOR 3 • FINGER TOUCH DRAW A SLIGHT AMOUNT OF CURRENT IS DRAWN 4 • THEORETICALLY AMOUNT OF CURRENT THAT DRIFTS THROUGH THE FOUR ELECTRODE SHOULD BE PROPORTIONAL TO THE DISTANCE FROM THE TOUCH POINT TO THE FOUR CORNER 5 • THE CONTROLLER PRECISELY CALCULATE THE PROPORTION OF THE CURRENT PASSED THROUGH THE FOUR ELECTRODES AND FINGER OUT THE X/Y CO-ORDINATE OF A TOUCH POINT
  17. 17. SEPARATE TOUCH PADS ARE ARRANGED ACCORDING TO A CO-ORDINATE SYSTEM EVERY POINT ON THE GRID GENERATES ITS OWN SIGNAL WHEN TOUCHED AND RELAYS THAT SIGNAL TO THE CONTROLLER THIS ALLOW TO CONTROLLER TO DETERMINE THE LOCATION AND MOVEMENT OF SIMULTANEOUS TOUCHES IN MULTIPLE LOCATION AN APPROACH TO MULTITOUCH
  18. 18. CONCLUSION WHAT SHOULD BE THE AIM OF SUCH TECHNOLOGY DEVELOPMENT?
  19. 19. NOW IN FUTURE FUTURE OF THE TECHNOLOGY
  20. 20. THANK YOU !
