9. A KEY CHALLENGES
TRADITIONAL COMPUTER USES KEYBOARD AND MOUSE BASED WIDGET IS
NO LONGER PREFERABLE

10. SURFACE INTERFACE
FOUR MAJOR COMPONENT
DIRECT
INTERACTION
MULTI-USER
EXPEREINCE
OBJECT
RECOGNITION
MULTI-
TOUCH
CONTACT

11. MULTI-USER EXPERIENCE
 A SINGLE TOUCH
SCREEN CAN
SUPPORT MORE
THAN ONE USER
 EACH USER CAN
INTERRACT
INDEPENDENTLY
WITH THE SURFACE

12. MULTI-TOUCH CONTACT
 ORDINARY TOUCH
PROVIDE ONLY SINGLE
TOUCH SENSING
 IN SURFACE MORETHAN
ONE TOUCH CAN SED

13.  IT MEANS WE CAN
INTERACT WITH THE
SURFACE BY USING
FINGER
 THIS PROVIDES A
NATURAL INTERFACE
EFFECT (NUI)
DIRECT-RECOGNITION

14. OBJECT RECOGNITION
 BAR TAG (DOMINO TAGS)
 INFRARED SENSITIVE
PATTERNS

15. 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.

17. RESISTIVE TOUCHSCREEN

CONTROLLER DECIDES
POSITION OF TOUCH

18. 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

19. 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

21. CONCLUSION
WHAT SHOULD BE THE AIM OF SUCH TECHNOLOGY
DEVELOPMENT?

22. NOW IN FUTURE
FUTURE OF THE
TECHNOLOGY
