Microsoft Surface

• Microsoft Surface is a multi-touch device that responds to natural hand signals and real-life objects.

• This interactive table top that can do everything a network device can do plus more without using a keyboard or a mouse.

The Science of Digital MediaDevice Hardware


Microsoft Surface

• The hardware inside the Surface can be divided to sub-systems.• PC• Camera system• light engine• table top

The Science of Digital MediaHardware Components


Microsoft Surface

• The hardware components which are built around Surface are• The power supply• The cool and quiet refrigerating system• The macro ATX mother board• The IO-panel • The compact audio panel

The Science of Digital MediaCameras


Microsoft Surface

• Surface has 5 cameras that work together to provide the output which end-users see on the device

• Each camera picks a quarter of the screen and the output is normalized and stacked together. This is the border for the application

The Science of Digital MediaCameras


Microsoft Surface

• The cameras have high end resolution to see and report back on the objects they detect.

• These objects are:• Finger• tag image • BLOB

• For example if a euro coin is placed on the top of the device, the image can be reported back and if you view the actual image produced by cameras you will see the pictures with a resolution which is the actual size of the coin.

• camera system produces 100 Mb/sec in total

The Science of Digital MediaInteracting with Input data


Microsoft Surface

• Developers can input the data in two ways• Using the data which is undergone with Identification

analysis uses the built in processing systems• To determine that the contact object is a finger, tag or

blob• Building the application with WPF gives the access to

platform specific methods and optimizes the capabilities to processing these contact types.

• The second type of input data is raw images which can be detected with the camera system.

• Like this you have to provide the image logic by yourself to the Identification analysis of the device and write a custom code to process these objects.

The Science of Digital MediaDevice Features


Microsoft Surface

• Microsoft Surface is vision based• This vision system has the capability to distinguish with

different types, such as objects hand or a finger and Surface can detect detail properties of these contacts such as direction they are pointing

• Microsoft Surface platform is built on top of Window 7 there for a network administrator can look after Surface just like other PC on the network.

• As a developer you have access to specialized SDK which is built on-top of .NET framework and surface simulation tool.



Microsoft Surface

• 5 key capabilities of Surface are:• Multi-touch• Multi-user• Object recognition• Direct interaction• 360-degree UI

• The multi-touch feature enables the Surface to recognize many points of contact at the same time

• you can increase an image size by touching the opposite corners and dragging those outwards



Microsoft Surface

• Not only from one finger as a typical touch screen but of 52 simultaneous contact points at once.

• Amazingly the device is touchable from the both sides• The shape and design of the Surface allows for multi-

users to interact with the device at once• If one table is not enough several tables can be linked

together even in the same room or remote distance to increase the multi user potential.

The Science of Digital MediaObject recognition


Microsoft Surface

• Object recognition feature enables the system to classify physical objects just by setting them on the Surface and to respond by displaying the suitable software related to that item.

• Fingers• As this is the first form of input these signals are

getting special attention. The device will detect the size, rotation and angle of the finger and reports back to the device

• Accessing this functionality and processing contact is done the similar way to the mouse, the events have even similar conviction and naming.



Microsoft Surface

• Tags• Tags can be placed on the Surface devices and the

device can read the information of these objects.• 8 bit tags• 128 identity tags

• These tags have much greater value range can and also be read to HEXA values and recognized by the system



Microsoft Surface

• BLOBS are categories which are detected by the camera system which cannot be classified as a finger or tag

• The vision system will assign a unique ID as it does for all other contacts and the basic size and shape

• Developers can use these BLOBs for wide range of uses• Blobs can only be orientated 180 degrees which is

different with fingers and tags which can be oriented 360 degree.

The Science of Digital MediaSell and Pricing information


Microsoft Surface

• Currently, Microsoft Surface is being marketed and sold directly to large scale leisure, entertainment and retail companies

• Other multi-touch technologies exist such as Jeff Han’s multi-touch wall which has demonstrated similar abilities as the Surface but is larger in size and costs around $100,000 and the SMART multi-touch tables, which have been referred to as “Surface Jr,” coming available next year for somewhere between $7,000 and $8,000

The Science of Digital MediaCase Study


Microsoft Surface

• Hard rock cafe• Schools• Casinos

The Science of Digital MediaSummary


Microsoft Surface

• Surface category is a brand new category in computer world. Microsoft Surface device is a functional implementation to the natural progression with user interfaces from CLI (Command-line interface) to GUI or to NUI (Natural User Interface).

• Microsoft Surface is a first device that allows end-users to interact directly with the application UI to the multi-touch sensitive screen

• With Microsoft Surface the occasions are endless with the ability to create custom applications for exact businesses or educational resolutions or building packaged applications for use across a range of industries or institutes.
