The document discusses Surface Computer, a multi-touch product from Microsoft that allows multiple users to interact with a 30-inch tabletop display using touch and gestures instead of a mouse or keyboard. It recognizes touch inputs, objects placed on its surface, and can be used collaboratively. The Surface uses infrared cameras beneath the screen to sense touch and objects, processes the information, and displays it using rear projection. It is currently used commercially but Microsoft hopes to expand it to consumers by making home versions that could use other surfaces.

3. What is Surface Computer?
• Surface Computer is a
forthcoming multi-touch product
from M icrosoft .
• 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” .
• With surface we can actually grab
data with our hands,& move
information between objects with
natural gestures & touch.

4. Features
Direct Interaction: Users can
actually grab digital information with their
hands , interacting with contents by touch &
gestures, without the use of a mouse &
keyboard.
Multi-touch: Surface computing
recognizes many points of contact
simultaneously , not just from one finger like a
typical touch screen , but up to dozens of items
at once.
Multi–User: The Surface’ s screen is
horizontal, allowing many people to come
together around it and experience a
“ collaborative, face–to–face computing
experience” .
Object recognition: Users can
place physical objects on the surface to trigger
different types of digital responses, including
the transfer of digital contents.

6. How does it work?
• The Surface is not a touch-sensitive screen device… The screen itself is not electronic.
• The Surface uses multiple infrared cameras beneath the screen/table top to sense objects, physical
touch, etc.
• The Surface “ recognizes objects based on shape or by using domino-style identification (domino
tags) on the bottom of the objects.”
• This information is processed and displayed using “ rear projection” .
(1) Screen: ” multitouch" screen. Can
process multiple inputs and recognize
objects by their shapes or coded "domino"
tags.
(2) Infrared: Once an object touches the
tabletop -> the light reflects back and is picked up
by infrared cameras.
(3) CP Uses similar components as current
U:
desktop computers -> Core 2 Duo processor, 2GB
of RAM and a 256MB graphics card. Wireless
communication -> WiFi and Bluetooth antennas.
Operating system -> modified version of
Microsoft Vista.
(4) Projector: Uses a DLP light engine
( rear-projection).

9. 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-Mobile, the Rio All Suite
Hotel & Casino in Las Vegas, Sheraton Hotels, Disney
Innovations House in California, Hotel 1000 in Seattle, Harrah’ s
Entertainment, and Starwood Hotels and Resorts Worldwide.

10. Surface Computer’ s Future…
• Surface will continue to be sold to and used by
restaurants, retail, leisure and public entertainment
venues.
•Microsoft goal is for consumers test the Surface in
commercial settings, and then want them in their own
households. Microsoft wants to expand to the
consumer market by making a product people can use
in their home environment (using other surfaces like
desks or making a version that hangs on the wall).
• Computer scientists hope to incorporate this kind of
technology in peoples’ daily lives… Future goals are to
surround people with intelligent surfaces
