RedTacton is a new human area networking technology that allows for high-speed data transmission of up to 10 Mbps by turning the surface of the human body into a transmission path. It was developed by NTT in Japan and uses photonic electric field sensors to overcome limitations of prior technologies that only achieved speeds of 40 bit/s over short ranges. RedTacton transmits data through the minute electric fields on the skin and enables communication through touch with devices like cards or receivers without direct contact or currents flowing into the body. Potential applications include touch advertising, intuitive device operations through touch, and security verification systems.

2. Red Tacton?
•RedTacton is a new Human Area
Networking technology [HAN]
•Human Area Networking (HAN) is a
technology that safely turns the surface of
the human body into a data transmission
path at speeds up to 10 Mbps between
any two points on the body.

3. History of HAN
•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.

4. History of HAN
•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!!

5. History of HAN
• These limitations were overcome by NTT
(Nippon Telegraph and Telephone
Corporation) located in Tokyo, Japan by
using photonic electric field sensors and
finally came up with a human area
networking technology called
„REDTACTON‟

6. Overview of RedTacton
•RedTacton is a new Human Area
Networking technology that turns the
surface of the human body as a safe,
high speed network transmission path.
•Communication is possible using any
body surfaces, such as the hands,
fingers, arms, feet, face, legs or toes.

7. Overview of RedTacton
• RedTacton works through shoes and
clothing as well.
• RedTacton uses the minute electric field
emitted on the surface of the human
body for data transmission.

8. What is RedTacton?
• TACTON: - “touch-act-on”
Meaning
“action triggered by touching”.
• RED: - It is an auspicious color
according to Japanese culture

9. How RedTacton works?

10. Mechanism of communication with
RedTacton

11. Human Safety
• No current flowing into the human body from
RedTacton devices.
• Displacement current occurring in the body is
small enough.
• RedTacton conforms to the safety guideline of
induced current.

12. Features
• RedTacton has three main functional
features…
Touch
•Communication with just a
touch
Broadband &
Interactive
•Broadband does not
deteriorate with
duplex operation and
simultaneous access
by many users
Any Media
•Works with many
transmission media
common in human
life

15. Applications
2. Intuitive Operations:
Touch to printer to print Instant private data exchange

16. Applications
3. Security Applications:
User verification and lock management at entrances

17. Prototypes
• Portable Card-Size Transmitter
Transmission: 230 kbps
Protocol: Proprietary Protocol
Transmission method: Unidirectional

18. Prototypes
• Embedded Receiver
Transmission: 230 kbps
Protocol: Proprietary: Protocol
Transmission method: Unidirectional
External Device Interface:

19. Advantages
• It does not require the electrode to be in direct
contact with the skin.
• Superior than Infrared, Wi-Fi technology.
• High-speed communication is possible between
two arbitrary points on the body.

20. Disadvantages
• It has no compelling applications that aren‟t
already available.
• Too costly.

21. Conclusion
•RedTacton is an exciting new technology for human
area networking.
•This technology definitely stands out with
perfection, when transfer of data is fast, feasible
and more importantly reliable. So, in few years
from now everything is going to fall under this
super technology.
