2.  To study what is surface computer?
 To study working & process of surface computer.
 To study technology used in surface computer.
 To study applications of surface computer.

3.  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.
 Instead of a keyboard and mouse, the user interacts
directly with a touch-sensitive screen.
 30-inch diagonal display in table like form factor. That’s
easy for an individuals or multiple people interact with
just like in the real world.
 Come to life for exploring, learning, sharing, creating ,
buying and much more.
 Available in retail stores, restaurants, hotels, casinos..

4.  2001: The product idea for Surface was initially
conceptualized by Steven Bathiche .
 2003:1 st prototype (t1 ) was produced to bill gets for
appruval
 2004: Microsoft built more than 85 early prototypes for
Surface.
 2005: The final hardware design was completed.
 2007: Interactive table top device was designed than
seamlessly bring both the physical and virtual words
into one.

7.  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.

8.  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.

9.  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.

10.  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. 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. Uses cameras to sense object,
touch and hand gesture
Displayed output using rear Projection
User input is then Processed

16.  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.

17.  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.

18.  Partner companies use the Surface in their hotels,
restaurants, and retail stores.
 Hotel lobbies, such as Sheraton Hotels, to choose meals
at restaurants, plan vacations and spots to visit from the
hotel room.
 Starwood Hotels plan to allow users to drop a credit
card on the table to pay for music, books, and other
amenities offered at the resort.
 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.

19.  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.

20.  Not portable and Very expensive
 Dim lighting required to avoid washing out of
screen.
 Barcode Required for an objects.
 This is insecure system.

21.  Surface computer is advanced computer
having large touch screen.
 Users can interact with the machine by
touching or dragging their fingertips and
objects such as paintbrushes across the
screen.
 We can use surface computer in different
hotels, Restaurants, casinos.
