This document provides an overview and summary of surface computing. It begins with the objectives of the presentation which are to define surface computing, describe the user interface evolution and technology used, and discuss applications and advantages/disadvantages. It then defines surface computing as replacing traditional GUI elements with everyday objects on a horizontal display. The history and development of surface computing from 2003-2011 at Microsoft is outlined. Key technologies used in surface computing are described as direct interaction, multi-touch, multi-user capability, and object recognition. Example applications and advantages are listed, along with disadvantages.

3. What is surface computing?
 Surface computing is the term for the use of a specialized
computer in which traditional GUI elements are replaced by
everyday objects.
 The Surface is a horizontal display on a table-like form.
 New way of working with computer that moves beyond the
traditional mouse and keyboard experience.
 Good in touch gesture rather than physical device like mouse and
keyboard

4. History of surface computing
 2003: The product idea for Surface was initially conceptualized
by Steven Bathiche .
 2007:1 st prototype (t1 ) was produced to bill gets for appruval
 2008: Microsoft built more than 85 early prototypes for Surface.
 2010: The final hardware design was completed.
 2011: Interactive table top device was designed than Smoothly
bring both the physical and virtual world into one.

8.  Direct Interaction :
User can “grab ” the digital information with their hands, interacting with a
content by touch and gesture. Without the use of mouse & keyboard.

9.  Multiuser:
Surface has 360 degree user interface & 30 inch reflective
surface so people can orient themselves on different sides
of the surface to interact with an application
simultaneously.

10.  Multi-touch
Multi-touch contact refers to the ability to have multiple contact points with an
interface, unlike with a mouse, where there is only one cursor.

11.  Object recognition
Object recognition refers to the device's ability to recognize the presence and
orientation of tagged objects placed on top of it.

12. Internal design
Camera & system unit
Infrared Emitter
Projector
Screen

13.  Screen: It has a 360-degree user interface, a 30-inch
reflective surface with a XGA DLP projector underneath
the surface which projects an image onto its underside
 Cameras: Microsoft Surface uses cameras and image
recognition in the infrared spectrum to recognize different
types of objects such as fingers, tagged items and shapes.
 System Unit: to perform an operations
 Infrared: 850-nanometer-wavelength LED light source
aimed at the surface. When an object touches the
tabletop, the light is reflected to multiple infrared
cameras with a net resolution of 1024 x 768, allowing it
to sense, and react to items touching the tabletop.
 Projector: An projector is used for displaying video,
images or computer data on a surface.

14. Optimized for 52 simultaneous inputs
4 people with all 10 fingers plus 12 objectsThe
software platform runs on a custom version.
 Wired Ethernet ,
Wireless 802.11 b/g,
Bluetooth 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
Hardware &software specification

17. Technology used in surface computer

18. Pen computing:
 Pen computing refers to a computer user-interface using
a pen and tablet, rather than devices such as a keyboard
and a mouse.
 Definition: A computer system employing a user-
interface using a pointing device plus handwriting
recognition as the primary means for interactive user input
is called pen computing.

19. Multi touch
 Multi-touch refers to the ability to simultaneously
register three or more distinct positions of input
touches.
 Multi-touch has been implemented in several different
ways, depending on the size and type of interface.

20. Applications:
 Partner companies use the Surface in their hotels,
restaurants, and retail stores..
 Starwood Hotels plan to allow users to drop a credit card
on the table to pay for music, books,
 In casinos users can do a range of things, such as watch
videos, view maps, order drinks, play games, and chat with
people between Surface tables.

21. Advantages
 We can direct interact with the computer without using mouse and
keyboard.
 Multiple user can interact at a same time.
 Any physical object can be directly recognized.
 Microsoft Surface responds to many points of contact simultaneously
 Designing made easier Time saving by eliminating many processes.
 Wireless communication between two object is possible.
 New and improved learning experience.

22. Disadvantages:
 Not portable and Very expensive.
 Barcode Required for an objects.
 This is insecure system.

23. Conclusion:
 Microsoft Surface is the future of computers.
 Microsoft Surface breaks down the traditional barriers
between people and technology.
 Surface takes existing technology to 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 open up new possibilities that weren’t
before.
