4. WHAT IS MICROSOFT
SURFACE?
Revolutionary multi touch computer
with different look & feel.
It is a surface with a computing
platform that responds to natural
hand gestures and real world objects.
Turns an ordinary tabletop into a
vibrant, interactive surface.
Provides effortless interaction with
digital content through natural
gestures, touch and physical objects.
Surface is a 30-inch display in a
table-like form factor that’s easy for
individuals to interact just like in the
real world.

5. WHAT IS MICROSOFT SURFACE?
Microsoft Surface represents a fundamental change in the
way we interact with digital content.
This uses a multi touch screen as user interface.
System composed of a horizontal touchscreen under a
coffee table-like surface, with cameras mounted below to
detect user interaction activities.
Surface can simultaneously recognize dozens and dozens
of movements such as touch, gestures and actual unique
objects that have identification tags similar to bar codes.
Surface computing-the technology behind.
Surface that comes to life for exploring, learning, sharing,
creating, buying and much more.

7. HISTORY
2001: Microsoft researchers
Steve Bathiche and Andy Wilson
developed idea of interactive table
that could understand the
manipulation of physical pieces.
2003: 1st prototype model named
T1. Team saw the value of the
surface computer beyond simply
gaming and began to favor those
applications that took advantage
of the unique ability of Surface to
recognize physical objects placed
on the table.

8. 2005 :Attention turned to
its form factor- Tub proto
type was designed.
2007:Final structure
finalised,interactive
tabletop device was built
that seamlessly brings
both the physical and
virtual worlds into one.

9. WHAT IS SURFACE COMPUTING?
Major advancement that moves beyond the traditional
user interface to a more natural way of interacting
with information.
It is a natural user interface that allows people to
interact with digital content the same way they have
interacted with everyday items such as photos,
paintbrushes and music their entire life: with their
hands, with gestures and by putting real-world objects
on the surface.
Surface computing opens up a whole new category of
products for users to interact with.

10. FEATURES OF SURFACE COMPUTING
Direct interaction : Users can
actually “grab” digital
information with their hands
and interact with content by
touch and gesture, without
the use of a mouse or
keyboard.
Multi-touch contact : Surface
computing recognizes many
points of contact
simultaneously, not just from
one finger, as with a typical
touch screen, but up to
dozens and dozens of items
at once.

11. FEATURES
Multi-user experience : The
horizontal form factor
makes it easy for several
people to gather around
surface computers
together, providing a
collaborative, face-to-face
computing experience.
Object recognition : Users
can place physical objects
on the surface to trigger
different types of digital
responses, including the
transfer of digital content.

12. INTERACTION METHODS
Two types of methods -
•Two Dimensional Typically, traditional surface types are two-dimensional and only require
two-dimensional touch interactions. Depending on the system, multi-touch gestures are
supported. These gestures allow the user to manipulate what they see on the surface by
physically touching it and moving their fingers across the surface.
•Three Dimensional Using depth aware cameras it is possible to make three dimensional
gestures. Such gestures allow the user to move in three dimensions of space without having
to come into contact with the surface itself, such as the methods used in DepthTouch .

13. STRUCTURE

14. 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) 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.

15. 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
Vista.
4) Projector: Microsoft's Surface uses the same DLP
light engine found in many rear projection HDTVs.
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.

17. WORKING
Microsoft Surface uses cameras to sense objects,
hand gestures and touch. This user input is then
processed and displayed using rear projection.
Microsoft Surface uses this rear projection system
which displays an image onto the underside of thin
diffuser.
Image processing system processes the camera
images to detect fingers, custom tags and other
objects such as paint brushes when touching the
display.
The objects recognized with this system are reported
to applications running in the computer so that they
can react to object shapes, 2D tags, movement and
touch.

20. ADVANTAGES
Large surface area to view different windows and
applications.
Data Manipulation - Selecting, moving, rotating and
resizing (manipulating objects on the screen is similar
to manipulating them in the manual world).
Quick and easy to use.
More Than One User –Several people can orient
themselves on different sides of the surface to interact
with an application simultaneously (Max 52 points of
touch).
Object Recognition - Increased functionality aiding
user in speed and ease of use
Time saving by eliminating many processes.

21. DISADVANTAGES
Not portable and very expensive.
Privacy - Open for many to view.
Screen Visibility - Glare, finger prints/dirt and human
interaction obscuring interface.
Poor Accuracy - Fat fingers are not as accurate as a mouse
or stylus.
Fatigue - Reaching across the table often can cause the
arms to ache.

22. FUTURE INNOVATIONS
Surface will continue to be sold to and used by restaurants, retail,
leisure and public entertainment venues.
Computer scientists hope to incorporate this kind of technology in
peoples’ daily lives… Future goals are to surround people with
intelligent surfaces (look up recipes on your kitchen counter or
table, control TV with coffee table, etc.
Eventually every household may have one in place of their
everyday coffee table.

23. CONCLUSION
Microsoft Surface is the future of computers.
Fundamentally changes the way we interact with
technology.
Surface takes existing technology 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 opens up new possibilities that weren't there
before.

24. Bluejacking

25. WHAT IS BLUEJACKING
 Bluejacking is the sending of unsolicited messages over
Bluetooth to Bluetooth-enabled devices such as mobile
phones, PDAs or laptop computers,etc.
 Bluetooth has a very limited range; usually around 10
meters on mobile phones, but laptops can reach up to
100 meters with powerful transmitters.

26. ORIGIN OF BLUEJACKING
 This bluejack phenomenon started after a Malaysian IT consultant
named “Ajack” posted a comment on a mobile phone forum.
 Ajack told IT Web that he used his Ericsson cellphone in a bank to
send a message to someone with a Nokia 7650.
 Ajack did a Bluetooth discovery to see if there was another
Bluetooth device around. Discovering a Nokia 7650 in the vicinity,
he created a new contact and filled in the first name with ‘Buy
Ericsson!' and sent a business card to the Nokia phone.

28. THE VARIOUS STEPS INVOLVED – IN MOBILE
 1. First press the 5-way joystick down.
 2. Then choose options.
 3. Then choose "New contact"
 4. Then in the first line choose your desired message.
 5. Then press done.
 6. Then go to the contact.
 7. Then press options.
 8. Then scroll down to send.
 9. Then choose "Via Bluetooth"
 10. Then the phone will be searching for enabled Devices.
 11. Then press "Select"

29. THE VARIOUS STEPS INVOLVED – IN COMPUTER/LAPTOP
 1. Go to contacts in your Address Book program (e.g.
Outlook)
 2. Create a new contact
 3. Enter the message into one of the 'name' fields
 4. Save the new contact
 5. Go to the address book
 6. Right-click on the message/contact
 7. Go to action
 8. Go to Send to Bluetooth
 9. Click on other
 10. Select a device from the list and double click on it

31. BLUEJACKERS OFTEN LOOK FOR THE RECEIVING PHONE TO
PING OR THE USER TO REACT. IN ORDER TO CARRY OUT A
BLUEJACKING,
the sending and receiving devices must be within 10 meters of one another.

32. RELATED CONCEPT
 BlueSnarfing:
“Bluesnarfing” is the term associated with
downloading any and all information from a hacked
device. Bluesnarfing is the theft of information from a
wireless device through a Bluetooth connection, often
between phones, desktops, laptops, and PDAs. This
allows access to a calendar, contact list, emails and text
messages. Bluesnarfing is much more serious in relation
to Bluejacking

33. HOW TO PREVENT BEING BLUEJACKED
To prevent being Bluejacked,
disable Bluetooth on the
mobile device when not in use.
The device will not show up
on a “Bluejacker’s” phone
when he/she attempts to send
a message and they do not
queue up.

34. CONCLUSION
Bluejacking is a technique by which we can interact with
new people and has ability to revolutionerise market by
sending advertisement about the product, enterprise etc. on
the Bluetooth configured mobile phone so that the people get
aware about them by seeing them on the phone.
