Red Tacton is a novel human area networking technology developed by NTT from Japan, utilizing the surface of the human body as a fast transmission medium for data at speeds up to 10 Mbps. It operates through minute electric fields emitted from the body, ensuring safety as the transceiver's electrodes are insulated to prevent current flow. While it claims advantages over existing technologies in terms of security and reduced network congestion, its practical applications are still limited and may be costly for widespread adoption.

4. What is Red Tacton?
Red Tacton is a new Human Area Networking technology.
Uses the surface of the human body as a safe, high speed network
transmission path.
It uses the minute electric field emitted on the surface of the human
body.

5. Developed by NTT from Japan.
Claims to send data over the surface of skin.
Attains a speed up to 10 Mbps --- equivalent to a fast broadband
connection.
Uses weak electric fields on the surface of human body instead of
relying on EM waves or light waves.

7. Principle
Red Tacton relies upon the principle that the optical properties of
an electro-optic crystal can vary according to the changes of a
weak electric field.

9. Experiment on Human Body

10. Human Safety
The transmitting and receiving electrodes of the transceiver are
completely covered with insulated film.
Impossible for current to flow from the transceiver to the human body.
When communication occurs, displacement current is generated by
the electrons in the body because body is subjected to minute
electrical fields.

11. How Red Tacton works?

14. Touching, gripping, sitting, walking,
stepping and other human
movements can be the triggers for
unlocking or locking, starting or
stopping equipment, or obtaining data.
Touch

15. Communication speed can
deteriorate
in crowded spaces due to a lack of
Bandwidth (wireless LAN).
Device drivers can be downloaded
instantly and executable programs
can be quickly sent.(RED
TACTON).

16. Any Media
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

18. FIRMO
Firmo Kit is used as an alternative to short-range wireless
security-card entrance/exit systems.
NTT claim Firmo provides a higher degree of security than
other technologies.

19. Body-based networking is more secure than broadcast
systems.
Network congestion due to fall in transmission speed in
multi user environments is avoided.

20. It has no compelling applications that aren’t already available.
Too costly.
Widespread marketing campaigns and education.

21. One-to-One services
An alarm sounds automatically to
avoid accidental medicine
ingestion.
Touching advertising and receive
information

22. Intuitive operation of personal information devices
Touch a printer to print
Instantaneous private
network via personal
handshake

23. Device personalization
Just sitting in the seat
triggers the car to load all
its presets as the way you
like.
Just touching a phone
makes it your own.

24. New behavior patterns
Connect to the
network just by
putting a lap-top on
a table
Wireless headset

25. Security applications
User verification
and unlocking
with just a touch
Automatic
access log for
confidential
document
storage

26. Conclusion
We conclude that, when we compare Red
Tacton with other technology present today it
can give a better performance over others
And we can say that to connect the network
with in short distances Red Tacton is best.
In this technology there is no problem of
hackers as our body is itself a media.

27. Future Developments
Reduction in size to be embedded in other
communication devices
