Microsoft Surface Computing

3

o It is a computer with different look & feel.

o A surface computer is a computer that interacts with the user through the surface of an ordinary object, rather than through a monitor and keyboard.

o Surface computer was created by Microsoft.

What is Surface Computing…?

4

o Its completely Multi-Touch based

o Able to recognize actual unique objects that have barcode (domino tag).

o Now the applications on surface computer are designed only for restaurants, hotels, retail and public entertainment venues.

o Will transform the way people shop, dine, entertain and live.

How Surface Computer Works

Camera• At a high level, Surface uses five cameras to sense objects. This user input is then processed and the result is displayed.

• Microsoft Surface can also identify physical objects that have bar-code-like tags (Domino tag).

Technology Behind Multi-Touch

• Based on Total Internal Reflection(TIR).• When one or more fingers touches the surface,

TIR pathway changes.

Four Key Attributes

Microsoft Surface Computing

Direct Interaction

Multi-touch Contact

Multi-user Experience

Object Recognition

15

Direct Interaction

Direct interaction means that, we can interact with the Surface by using our fingers.

No other input device is needed to give input.

This provides a natural interface effect.

Microsoft Surface Computing

Direct Interaction

16

Multi-user Experience

A single touch screen can support more than one user. Each user can interact independently with the surface.

Multi-user Experience

17

Multi-Touch Contact

Microsoft Surface Computing

Ordinary touch screens provide only single touch sensing.

In surface more than one touch can be recognized at the same time.

Multi-Touch Contact

18

Object Recognition

Object recognition is done in the surface by using special bar codes called Domino tags.

These are infrared sensitive patterns which are read by the infrared sensing cameras inside the surface.

Object Recognition

19

Applications:-

• Instantly compares while shopping.• Interaction with digital content by share, drag

and drop digital images.• Surface Restaurant.• Quickly browse through play list entries

dragging favorite song to the current track…

Instantly compares while shopping

• We can directly compare different products just by placing them on the surface.

• This is done using object recognition technology.

21

Interaction with digital content by share, drag and drop digital images

• Digital images are manipulated, shared & sent via technologies like Wi-Fi, Bluetooth, etc..

Dragging of Images

22

Surface Restaurant

• Orders can be placed on the Surface from a sliding menu.

23

•Microsoft surface applications can be written in Windows Presentation Foundation(WPF).

Applications Development

• Also supports XNA tool kit.

24

Advantages

• Multi users• Seamless- Users have more control of technology- ordering

food or manipulating photos fast.• Educational

Microsoft Surface Computing

25

Disadvantages

•Expensive.•Currently designed only in some areas.•Making it small enough to fit into the

computer environment

26

In Future

• The future : As form factors continue to evolve, surface computing will be in any number of environments – school, businesses, homes and any number of forms.

Microsoft Surface Computing

Conclusion

‘A computer on every desktop.’

Now we say,

‘Every desktop will be a computer.’
