Surface computing is the use of a specialized computer GUI in which traditional GUI elements are replaced by intuitive, everyday objects. Instead of a keyboard and mouse, the user interacts directly with a touch-sensitive screen. It has been said that this more closely replicates the familiar hands-on experience of everyday object manipulation. Early work in this area was done at the University of Toronto, Alias Research, and MIT.Surface work has included customized solutions from vendors such as LM3LABS or GestureTek, Applied Minds for Northrop Grumman.Major computer vendor platforms are in various stages of release: the iTable by PQLabs, Linux MPX,the Ideum MT-50, interactive bar by spinTOUCH, and Microsoft PixelSense (formerly known as Microsoft Surface).

In 2001, Stevie

Research began
brainstorming
concepts for an
interactive table. Their
vision was to mix the
physical and virtual
worlds to provide a
rich, interactive

This
conversation was the beginning of an idea that
would later result in the development of Surface, and
over the course of the following year, various people
at Microsoft involved in developing new product
concepts, including the gaming-specific PlayTable,
continued to think through the possibilities and
feasibility of the project. Then in October 2001 a
virtual team was formed to fully pursue bringing the

In early 2003, the
team presented the
idea to Bill Gates,
Microsoft Chairman,
and within the month
the first prototype
was born, based on
an IKEA table with a
table cut through its
top and a sheet of
architect vellum as a
diffuser.

were built, including the
“tub” model that was

Direct Interaction
Multi-touch
Contact
Multi-user
Experience
Object
Recognition

14. Direct Interaction
Direct interaction
means that, we can
interact with the
Surface by using our
fingers.
No other input device
is needed to give input.
This provides a natural
interface effect.
Microsoft Surface
Computing

15. Microsoft Surface
Computing

Direct Interaction
 Users can actually “grab” digital information
with their hand and interact with content
through touch and gesture, without the use of
a mouse or keyboard. Customers will benefit
from Microsoft Surface instantly. Interacting
with content is natural, simple, intuitive, and
fun.

16. Multi-user Experience
A single touch screen
can support more
than one user.
Each user can
interact
independently with
the surface.
Microsoft Surface
Computing

17. Microsoft Surface
Computing
17
Multi-user Experience
 The 30-inch diagonal display and the
horizontal form factor makes it easy for
several people to gather around surface
computers together, providing a
collaborative, face‐to‐face computing
experience.

18. Multi-touch Contact
Microsoft Surface
Computing
18
Ordinary touch
screens
provide only single
touch sensing.
In surface more than
one
touch can be
recognized
at the same time.

19. Microsoft Surface
Computing

 Multi-touch is an enhancement to touchscreen
technology, which provides the user with the
ability to apply multiple finger gestures
simultaneously onto the electronic visual display
to send complex commands to the device.
Multi-touch Contact
 Surface computing recognizes many points of
contact simultaneously, not just from one finger
as with a typical touch screen, but up to dozens
and dozens of items at once.

20. Object Recognition
Object recognition is
done in the surface by
using special bar
codes called Domino
tags.
These are infrared
sensitive patterns
which are read by the
infrared sensing
cameras inside the
surface.
Microsoft Surface
Computing

21. Microsoft Surface
Computing

Object Recognition
 Users can place physical objects on the
surface to trigger different types of digital
responses, including the transfer of digital
 object recognition is almost exactly the same
as touch recognition

22. Microsoft Surface
Computing
22
Object Recognition
 Microsoft Surface can also recognize specific
objects, what they are, and interact with them !
In order for Surface to recognize what an object
is you have to put a tag on it. These are called
byte tags, and they look a lot like a domino:

23. Microsoft Surface
Computing
23
Object Recognition
 When an object with a tag is placed on the
Surface, the relation between the tag and the
object is recognized, and from there on out, it
is recognized as that object. So if you put a
camera down with a tag in relation to that
camera, the Surface recognizes the object as
a camera

24. Technology Behind Surface
• Uses IR cameras to sense objects, hand gestures and
finger touch.
• Uses a Rare projection system which displays on to the
underside of a thin diffuser.
Microsoft Surface
Computing
24

25. Technology Behind Surface Contd…
•Objects such as fingers are visible through
the diffuser by series of IR cameras,
positioned underneath the display.
•An image processing system processes the
camera images to detect the fringes.
•Objects recognized are reported to the
applications running in the computer so
that they can react to objects shape,
movement and touch of the finger.

26. What is Microsoft Surface?
o It is a computer with different look & feel.
o Surface does not have any keyboard or mouse.
o This uses a multi touch screen as user interface.
