3. INTRODUCTION
 RedTacton is a new Human Area networking technology, which is under
development that uses the surface of the human body as a safe, high
speed network transmission path.
 Technically, it is completely distinct from wireless and infrared
technologies as it uses the minute electric field emitted on the surface of
human body as medium for transmitting the data.
 RedTacton can achieve duplex communication over the human body at a
maximum speed of 10 Mbps.
 RedTacton involves initiating communication with a touch that could result
in a wide range of actions in response. Transmission path is formed when
a part of the human body comes in contact.
 RedTacton works through shoes and clothing as well.

4. HISTORY
 The concept of intra-body communication was first proposed by IBM
in 1996.
 This communication mechanism was later evaluated and reported by
several research groups around the world.
All those reported technologies had two limitations.
 The operating range through the body was limited to a few tens
of centimeters.
 The top communication speed was only 40 bit/s!!
These limitations were overcome by NTT (Nippon Telegraph and
Telephone Corporation) located in Tokyo, Japan by using
photonic electric field sensors and finally in 2005 they came up
with a human area networking technology called ‘REDTACTON’‘REDTACTON’

5. What is RedTacton?
Red : a warm color to emphasis warm and cordial communications.
TACTON : Action triggered by Touching.
• RedTacton utilizes a point to point network, known as a
Pico net that allows information to be exchanged between
two transceivers without the need for a server to store or
process information.
Above Figure shows RED TACTON Device

6. How Red Tacton works ?
Figure shows the working of the REDTACTON device over the surface of our body.

7. How it works?
 RedTacton operates on the idea that optical properties of
an electro-optic crystal can vary according to the changes
of a weak electric field.
 After contract with another RedTacton enabled device, the
transmitter induces a weak electric field on the surface of
the body.
 The weak electric fields pass through the body to a
RedTacton receiver, where the weak electric fields affect
the optical properties of an electro-optic crystal.
 The extend to which the optical properties are changed is
detected by laser light, which is then converted to an
electrical signal by a detector circuit.

8. HUMAN SAFETY
 RedTacton transceiver electrodes are covered with an insulating
film, so there is no way that current from RedTacton can flow into
the user's body.
 Note however that, just like the weak electromagnetic waves
produced by most common electrical appliances, a faint
modulating displacement current does pass through the body
when using RedTacton .
 The level of displacement current involved is considered
harmless and is in full compliance with the "Radio Frequency-
Exposure Protection Standard <RCR STD-38> established by
the Association of Radio Industries and Businesses (ARIB).

9. WHAT DOES IT DO?
• When using a RedTacton device, the human body
effectively becomes an Ethernet cable, so the body can use
its electrical field to connect devices to networks or the
internet.
• For example, if a person wearing a RedTacton device sat
at a table with RedTacton capabilities that was connected
to the Internet, the laptop would immediately be connected
to the internet.
• Seems similar to a wireless network connection, but it is
not. There is a physical connection, the person.
• The connection is more secure and does not slow down if
many people are using the same connection, as a wireless
connection does.

10. WORKING PROCEDURE
1. Transmitter sends data
2. Transmitting transceiver creates a change in the field
3. Field from human body dissipates into earth
4. Electric field is received using sensing technology
5. Receiving transceiver recognizes the change in the electric field
6. Sensing technology measures the weak electric fields induced.
7. Electro-optical crystal uses laser to convert and read the signal

11. Why RedTacton?
• Bluetooth, infrared etc. were the most commonly used
techniques for data transmission.
• But these short-range wireless communication systems have
some problems.
• Throughput is reduced by packet collisions
• The principle drawback of infrared communications (IrDA) is
the tight directionality of beams between terminals needed
for the system to be effective

12. • The ultimate human area network solution to all these
constraints of conventional technologies is “intra body”
communication, in which the human body serves as the
transmission medium.
• Human area networks would solve all the problems
including throughput reduction, low security, and high net
-work setup costs.

13. FUNCTIONAL FEATURES OF RED TACTON
RedTacton has three main functional features:
1. Touch
2. Broadband & Interactive
3. Any media

14. TOUCH
Communication with just a touch or a step!
 Touching, gripping, sitting, walking, stepping and other
human movements can be the triggers for unlocking or
locking, starting or stopping equipment, or obtaining data.
 Using RedTacton, communication starts when terminals
carried by the user or embedded in devices are linked in
various combinations through physical contact according
to the human's natural movements.

15. BROADBAND & INTERACTIVE
Bandwidth does not deteriorate even with duplex operation &
simultaneous access by many users!
• Duplex, interactive communication is possible at a maximum speed of
10Mbps.
• Because the transmission path is on the surface of the body, transmission
speed does not deteriorate in congested areas where many people are
communicating at the same time .
Figures shows difference between
wireless LAN and RedTacton

16. ANY MEDIA
Works with many transmission media common in human life!
In addition to the human body, various conductors and dielectrics can be
used as transmission media. Conductors and dielectrics may also be
used in combination.
A communication environment can be created easily and at low-cost by
using items close at hand, such as desks, walls, and metal objects. But
there is one limitation on the length of the conductor to be propagated,
on installation locations, and on the thickness of the dielectric to be
passed through.
DIELECTRICS
(Signals can pass through materials)
CONDUCTORS
(Signals travel along surface)

17. APPLICATIONS
• Information recorded in the RedTacton device is sent to the
touched objects.
• Appropriate service is provided based on the information received
by the RedTacton receiver.
Elimination of Human Errors:
One to One services
 RedTacton devices embedded Medicine bottles transmit
information of medicine attributes.
 If the patient touches the wrong medicine, an alarm will trigger on
the terminal he is carrying.
 Patients wearing the device could quickly and securely transmit
their medical history to doctors.
 Avoidance of risks at construction sites: an alarm sounds if special
equipments are handled by anyone other than supervisors

18. Device personalization
• Personalization of mobile phones :
 You own phone number is allocated & billing commences.
 Automatic importing of personal address book and call history.
• Personalization of automobiles :
 The seat position and steering wheel height adjust to match the
driver just by sitting in the car.
 The driver’s home is set as the destination in the car navigation
system.
 The stereo plays the driver's favorite song.
 Car alarm systems could also get more secure
using RedTacton.

19. New behavior patterns :
Tables, walls, floors and chairs can all act as conductors and dielectrics,
turning furniture and other architectural elements into a new class of
transmission medium.
For example, a user could have instant access to the Internet merely by
placing a laptop onto a conductive tabletop
Marketing applications :
By touching or standing in front of items
they are interested in,
consumers can get more in-depth information.
Inside a shop, shoppers can view related
information on their mobile terminals
immediately after touching a product.

20. Security applications :
• User verification and lock management at entrance:
RedTacton could be installed on doors, cabinets and
other locations calling for secure access, such that each
secure access could be initiated and authenticated with a
simple touch
• Gun Security: If a RedTacton transceiver were implanted
in the gun and programmed to a transceiver worn by a
soldier, then only that soldier
could fire the weapon.
• Confidential document
management
User verification and unlocking with just a
touch

21. Applications
• Instant private data exchange
Touch printer to print
Electronic business cards can be shared
by shaking hands
User verification and unlocking with just a touch

23. ADVANTAGES
• RedTacton does not require the electrode to be in direct
contact with the skin.
• Can transmit data at a rate higher than that of peer
technologies. (max. of 10Mbps)
• RedTacton transceivers are programmable and we can
decide what to share with whom and what devices you
communicate with.
• Each communication occurs in separate channels.
• Transmission speed does not deteriorate even though the
number of users increases.

24. • Data loss during transfer is less
• Use of minimum amount of power (of some milli-volt
range)
• Security is more.
• No problem of hackers . It is very hard to pick up stray
electronic signals radiating from the body.
• More secure than Bluetooth.
• Superior than infrared technology & Wi-Fi.

25. COMPARISON WITH OTHER NETWORKS
 Wireless communication creates connections when signals
arrive, allowing for easy connections because connectors
are unnecessary. However, seen from another aspect, the
arriving signals can be intercepted, so security becomes an
issue.
 Wired communication transmits data between two
connection points, so interception is difficult and security
can be considered to be high. However, connectors and
cables are a nuisance.

26.  RedTacton is situated directly between wireless and wired
communication. In other words, RedTacton allows for easy
connection without connectors, while at the same time
allowing transmission of data only between two contact
points. It thus has the feature of being difficult to intercept.
 The focus on ubiquitous service has brought about the
shortening of distances in communication. RedTacton is
positioned as the last 1m solution to ultimate close-range
communication

27. COMPARISON WITH OTHER NETWORKS
Above Figure shows the comparison of RED TACTON device with other
networks with respect to distance.

28. ADVANTAGE OVER BLUETOOTH
• RedTacton claims to be able to send data over the human skin
surface at transfer speeds of up to 10Mbps, or better than a
broadband T1 connection.
• Maximum speed offered by Bluetooth is 3Mbps.
• According to Tom ZimmermanTom Zimmerman, inventor of the IBM personal
networking system, body-based networking is more secure
than broadcast systems, such as Bluetooth, which have a
range of about 10m.The issue is that with Bluetooth, it is
difficult to rein in the signal and restrict it to the device you
are trying to connect to. In a busy place there could be
hundreds of Bluetooth devices within range. The signal can be
tapped into and used by others.

31. CHALLENGESCHALLENGES
• The obvious barrier to entry is that the cost and time to develop
HAN TECH. is very expensive.
• As a new technology HAN need to gain popularity among users to
help pull the technology into the marketplace instead of having it
pushed upon them.
• Widespread marketing campaigns will need to be developed to
highlight the benefits of HAN technology to facilitate its adoption.
• Not useful unless many people adopt it..
• It can be useful within few centimeters only.

32. CONCLUSIONCONCLUSION
Many areas can benefit from this technology. Human society
is entering an era of ubiquitous computing, where everything is
networked. RedTacton is gearing up to compete with Bluetooth,
Zigbee, IrDA (infrared data association), UWB (ultra wide band).
So we can clearly say that, this technology will spawn
revolutionary changes in the modern communications and become a
pivot technology. When we compare RedTacton with other
technologies, RedTacton will give a better performance over other.
If RedTacton is introduced into cyber market it brings a marvelous &
tremendous change and will be adopted by many more people.
So, in few years from now everything is going
to fall under this super technology. And, finally I conclude,
“FUTURE BELONGS TO RED TACTONRED TACTON ”
