3D surface flattening is a hot research theme in the field of computer aided design and
manufacture. A numerical simulation method for surface flattening is proposed in this
paper. First of all, a 3D surface is flattened to a 2D pattern by Geodesic curvature
method. Then an accurate 2D pattern is created through building up the mass-spring
model and carrying out the interactive operation. On the other hand, it can reduce the
strain energy and improve the accuracy of 2D pattern appearance by way of trimmed
surface. Finally, several examples of developable and non-developable surfaces are
simulated in order to prove the feasibility of the method in this paper.
1.INTRODUCTION: A computer in the form of a table, using the hard acrylic tabletop
as a high-resolution screen. First product from Microsoft's previously secret Surface
Computing team, which has 120 employees.

It may look like an old barroom Pac-Man machine, but Microsoft's Surface is the
company's first product to make use of a new interface technology the firm calls "surface

Surface Computer users can finger-paint digitally, resize and interact with photos and
videos, and even "digitize" some real-life events, such as splitting up a restaurant bill and
researching wines. The Surface Computer can recognize some real-world objects and
creates onscreen versions to interact with the Surface Computer isn't intended for

Home use--at least not yet. Instead, the tabletop system is expected to be used as an
interactive kiosk for businesses, restaurants, a After years of covert development,
Microsoft says it will release a computer that uses the tabletop as its high-resolution
display, recognizes objects placed on the surface and skips the traditional keyboard and
mouse in favor of fingers on the screen.

1.1) Microsoft is the first major technology company that introduced surface
computing to the world markets as a commercially ready product.
1.2) This software giant has built a new touch screen computer where mouse and
keyboards are long forgotten versions. You can call it Surface Table-top.

1.3) Surface computing is a concept for an interactive table with a motive to combine
the physical and the virtual worlds to provide a rich interactive experience. It is
completely an intuitive and liberating way to interact with digital content which blurs the
lines between the physical and virtual worlds.

1.4) The launch of this product by Microsoft has marked the beginning of a new era in
the technology sector and a user-interface revolution. Microsoft Surface Computer Table,
Microsoft’s first of its kind, provides effortless interaction without the old traditional
methods of computing.

The surface itself isn't touch-sensitive, but a series of cameras inside the table can see
when someone places or drags a finger, hand or any other object on or across the tabletop
screen. Internal projector lights screen from beneath.

i) Interface: People can use their hands to touch and move virtual objects on the screen,
just as they would with a mouse on a traditional PC. The system also can recognize
objects placed on the surface, based on their shape or on special codes affixed to them
ii)Size: 22 inches high, 21 inches deep, 42 inches wide, with 30-inch screen
2.1) Screen: A diffuser turns the Surface's acrylic tabletop into a large horizontal
"multitouch" screen, capable of processing multiple inputs from multiple users. The
Surface can also recognize objects by their shapes or by reading coded "domino" tags.
2.2) Infrared: Surface's "machine vision" operates in the near-infrared spectrum, using
an 850-nanometer-wavelength LED light source aimed at the screen. When objects touch
the tabletop, the light reflects back and is picked up by multiple infrared cameras with a
net resolution of 1280 x 960.
2.3) CPU: Surface uses many of the same components found in everyday desktop
computers — a Core 2 Duo processor, 2GB of RAM and a 256MB graphics card.
Wireless communication with devices on the surface is handled using WiFi and
Bluetooth   antennas    (future   versions   may incorporate    RFID    or   Near   Field
Communications). The underlying operating system is a modified version of Microsoft
2.4) Projector: Microsoft's Surface uses the same DLP light engine found in many rear-
projection HDTV’s. The footprint of the visible light screen, at 1024 x 768 pixels, is
actually smaller than the invisible overlapping infrared projection to allow for better
recognition at the edges of the screen.


3.1)A Surface computer is able to recognize physical objects: Surface computer can
this means that when a customer simply sets a wine glass on the surface of a table This
surface computer could provide them with information about the wine they’re ordering,
pictures of the vineyard it came from and suggested food pairings tailored to that
evening’s menu. The experience could become completely immersive, letting users
access information on the wine-growing region and even look at recommended hotels and
plan a trip without leaving the table.

3.2) broadly we can breakdown surface computer’s style of usage in following parts:

+ Direct interaction. Users can actually “grab” digital information with their hands,
interacting with content by touch and gesture, without the use of a mouse or 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 horizontal form factor makes it easy for several people to gather
around surface computers together, providing a collaborative, face-to-face computing
+ Object recognition. Users can place physical objects on the surface to trigger different
types of digital responses, including the transfer of digital content
This Surface computer may capture every places of computer like Star wood Hotels,
Resorts, Casino, and even though in coffee tables also. You can wonder but its fact.
4.1) Star wood Hotels & Resorts Worldwide
Star wood Hotels & Resorts will initially launch Surface at Sheraton Hotels & Resorts,
Star wood’s largest and most global brand. Surface will help bring interaction,
connectivity and play to Sheraton hotels’ new lobby experience, currently being rolled
out in key cities worldwide. To provide guests with greater service, unique experiences
and entertainment, Sheraton embraced Surface as a key component of its lobby

4.2) Comparison Shopping
Tiny tags on products will allow partners such as T-Mobile to use Surface kiosks to give
customers more information about products in the store
4.3) There’s a Jukebox in Your Table
The Surface machine is networked and infinitely flexible. It will offer some intriguing
new ways to organize to play music and watch television ("We view its Migration as
similar to that of plasma TVs," says Pete Thompson, Microsoft's general manager for
surface computing).

4.4) How About a Little Drawing?
U can recall your childhood day activities of drawing diagrams in slate…..but not in a
actual slate but it’s a “Virtual slate”.
So within in a short while of time, world is completely switching to new era of personal
computer to Surface computer..
Computer scientists see technologies such as surface computing and multitouch as the
key to a new era of ubiquitous computing, where processing power is embedded in
almost every object and everything is interactive.
Short-term success for a technology can be measured by how much attention a product
gathers when it is new. Long-term success is measured by how effectively that product
disappears into the everyday routine of life. Surface computing has enormous potential to
do both — it is a splashy new computer interface, surrounded by hype, but it is also, quite
literally, furniture. It is a technology in its infancy, where even the engineers behind it
can't predict its full impact; but the possibilities are everywhere, underhand and underfoot
— on every surface imaginable.
