This presentation introduces surface computers. Surface computers use cameras and projectors instead of keyboards and mice to allow for direct interaction. Users can touch and move objects on the large multi-touch display screen. Applications include using surface computers in hotels, restaurants, and casinos to browse menus, plan activities, view maps and play games. Some advantages are direct interaction without peripherals and multiple simultaneous users. However, surface computers also have disadvantages like high costs and need for dim lighting.

2. Objectives:
 To study what is surface computer?
 To study working & process of surface
computer.
 To study applications of surface computer.
 To study advantages & disadvantages of surface
computer

3. What is surface computer?
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.
Available in retail stores, restaurants, hotels,
casinos..

4. History of surface computer
 2001: The product idea for Surface was initially
conceptualized by Steven Bathiche .
 2003:1st 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.

6. Features

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.

11. Design & Working of
surface computer

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

15. Applications:
 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.

16. 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.

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

18. Conclusion:
 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.
