Surface computing allows for natural interactions with digital information through direct touch interaction, multi-touch detection, support for multiple simultaneous users, and object recognition. It utilizes technologies like Microsoft Surface, which uses infrared cameras under the display to sense touch input and objects placed on the screen without needing a touch-sensitive surface. Surface computing provides an intuitive interface and has applications in fields like education, retail, and business meetings.

1. SURFACE COMPUTING

2. What is surface computing?
A form of computing that offers “a natural way of
interacting with information,” rather than the
“traditional user interface”
Surface computing typically includes four key
attributes:
 Direct Interaction
 Multi–Touch
 Multi–User
 Object Recognition

3. DIRECT INTERACTION
The ability to "grab"
digital information with
hands - interacting with
touch/ gesture, not with a
mouse or keyboard.

4. MULTI – TOUCH
The ability to recognize
multiple points of contact
at the same time, not just
one (Ex. One finger, like
with most touch screens),
but dozens.

5. MULTI – USER
The Surface’s screen is
horizontal , allowing many
people to come together
around It and experience a
“collaborative, face–to–
face computing
experience”

6. OBJECT RECOGNITION
Physical objects can be
placed on the Surface’s
screen to “trigger different
types of digital responses”
(Ex. cell phones, cameras,
& glasses of wine)

7. Developments done till now.

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 the
screen/table top to sense objects, physical touch, etc
 The Surface “recognizes objects based on shape or by
using
domino-style identification (domino tags) on the bottom
of the objects ”
 This information is processed and displayed using
“ rear projection ”

10. Working of Microsoft Surface
Screen: Diffuser -> ”multitouch" screen. Can process multiple
inputs and recognize objects by their shapes or coded "domino"
tags.
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.
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 Microsoft
Vista.
Projector: Uses a DLP light engine ( rear-projection HDTVs).

11. Where is it used?
seminars
Easy data transfer
Airports
Shopping malls,hotels,etc…
Work place
transportation

12. R&D
 Research work is going on several top universities
like MIT (Massachusetts Institute of technology)
with a innovation named SIXTH SENSE. This is an
application of surface computing.
 Research on building user defined gestures that
are used in surface computing that make the
graphical representation more intuitive…

13. ADVANTAGES
Data representation/transfer is more
intuitive
User friendly
No use of input/output devices like mouse
keyboard etc . . .
Easily portable . . .

15. Conclusion
Surface takes existing technology and
presents it in a new way. It isn't 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 weren't there before
