• 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.

• 2003: The product idea for Surface was initially conceptualized by Steven Bathiche .

• 2005: 1st prototype (t1 ) was produced to bill gets for approval

Figure 1:Prototype [1]

• 2006: Microsoft built more than 85 early prototypes for Surface.

• 2008: The final hardware design was completed.

• 2010: Interactive table top device was designed than seamlessly bring both the physical and virtual words into one.

Figure 2: Complete prototype [1]

• 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.

Figure 3 :User Interaction [2]

• 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.

Figure 4: Multiple User [2]

• 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.

Figure 5 : Multi-touch [3]

• Object recognition: Object recognition refers to the device's ability

to recognize the presence and orientation of tagged objects placed on top of it.

Figure 7: Internal Design

• 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.

Uses cameras to sense object, touch and hand gesture

Displayed output using rear Projection

User input is then Processed

• 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.

• 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.

• 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.

• 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.

• Not portable and Very expensive• Dim lighting required to avoid washing out of

screen.• Barcode Required for an objects.• This is insecure system.

• 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.
