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

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.

View

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.

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.

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.

Object recognition

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

Internal design

Camera & system unit

Infrared Emitter

Projector

Screen

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.

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

Technology used in surface computer

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.

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.

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.

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.

Disadvantages:

Not portable and Very expensive.

Barcode Required for an objects.

This is insecure system.

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.
