Surface computing is a new form of human-computer interaction that allows users to directly manipulate digital content on a horizontal display surface using hand gestures and physical objects. Microsoft Surface, introduced in 2007, is a pioneering surface computing platform that uses infrared cameras and multi-touch capabilities to recognize touch input from multiple users simultaneously. In the future, surface computing may be integrated into many everyday environments like homes and offices through intelligent horizontal displays.

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. 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. ∗ 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. Key attributes
A form of computing that offers “a natural way of
interacting with information,” rather than the
“traditional user interface.”
Direct Interaction: T ability to "grab" digital
he
information with hands - interacting with
touch/gesture, not with a mouse or keyboard.
M ulti–Touch: T ability to recognize multiple points
he
of 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,
he
allowing many people to come together around it
and experience a “collaborative, face–to–face
computing experience”.
Object R ecognition: Physical objects can be placed
on the Surface’s screen to “trigger different types of
digital responses” (E cell phones, cameras, &
x.
glasses

7. How is the Surface used?
•W ireless! Transfer pictures from camera to Surface and
cell phone. “Drag and drop virtual content to physical
objects.”
• Digital interactive painting
• At a phone store? Place cell phone on the Surface and
get information, compare different phones, select service
plan, accessories, and pay at table!
• At a restaurant? View menu, order drinks and meal at
your table! It’s a durable surface you can eat off of
(withstands spills, etc.). Need separate checks? Split bill
at and pay at table.
• P games and use the Internet.
lay
•Watch television
•Jukebox! Browse music, make play lists.
•Billboard for advertising
•Maps

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, physical
touch, etc.
• T Surface “recognizes objects based on shape or by using domino-style identification (domino tags)
he
on 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).

9. FTIR: The DIY version
What 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. 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. 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. Applications
1 Water
∗Water is used as an "attract mode" for
the Surface desktop, and it is certainly
attractive.
∗A unique feature that comes
preinstalled with Surface is the pond
effect "Attract" application. Simply, it is
a "picture" of water with leaves and
rocks within it.
∗By touching the screen, you can
create ripples in the water just like you
were putting your hand into a real
stream
∗Additionally, the pressure of touch
alters the size of the ripple created,
and objects placed into the water
create a barrier that ripples bounce off,
just as they would in real life

13. 2.Music
∗The Music application works
like a virtual jukebox,
displaying music arranged by
album and allowing the user
to flip over albums, select
songs, and drag them to the
"Now Playing" section. In
addition to playing music that
is already stored on the u it's
hard drive, Music can also
transfer songs from portable
music players

14. 3.Photos
∗Sharing photos is a much more
unrestricted activity. Photos are
arranged into albums that look like
piles. Tapping the pile once spreads
it around the screen and from there
user can drag, rotate, and resize the
images. Since Surface can detect
many touches at the same time,
multiple people can sort and resize
pictures.

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 in
California, H otel 1000 in Seattle, Harrah’s Entertainment, and
Starwood H otels and Resorts W orldwide.

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. 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. 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. 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 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.
 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.
