Have you ever

imagine
d

that soon our body can be the backbone of a broadband personal data network linking our mobile phone
or MP3 player to a cordless headset, our digital camera to a PC or printer, and all the gadgets one carries around to each ot
her?
Japan’s Nippon Telegraph

and Telephone Corp. have developed a system that can do these things and others by using your body
to create a high
-
speed computer network called RedTacton.

In this paper we are
explaining the uni
que new functional features and
enormous potential of
RedTacton as a Human

Area Networking technolo
gy. Here, the human
body acts as a

transmission medium supporting
half duplex communication at
10Mbit/s.


Keywords
: RedTacton, Electric field sensing


INTRODUCTION:

RedTacton

enables the first practical Human Area Network between body
-
centered electronic devices and PCs or other network
devices embedded in the environment via a new generation of user interface based on totally natural human
actions

A

person equipped with a sen
sor can exchange data with another person carrying a sensor by shaking hands, and between a person
and a device by touching it, walking on it or sitting on it.

RedTacton

is a new Human Area Networking technology that uses the surface of the human body as a

safe, high speed network
transmission path.
RedTacton

uses the minute electric field emitted on the surface of the human body. Technically, it is completely
distinct from wireless and infrared. A transmission path is formed at the moment a part of the hum
an body comes in contact with a
RedTacton
transceiver. Physically separating ends the contact and thus ends communication. Using
RedTacton,

communication
starts when terminals carried by the user or embedded in devices are linked in various combinations ac
cording to the user's natural,
physical movements. Communication is possible using any body surfaces, such as the hands, fingers, arms, feet, face, legs or
torso.
RedTacton
works through shoes and clothing as
well.




HOW REDTACTON WORKS?

Using a new supe
r
-
sensitive photonic electric field sensor,
RedTacton

can achieve duplex communication over the human body at
a maximum speed of 10 Mbps.


1. The
RedTacton

transmitter induces a weak electric field on the surface of the body.

2. The
RedTacton

receiver senses changes in the weak electric field on the surface of the body caused by the
transmitter.

3.
RedTacton

relies upon the principle that the optical

properties of an electro
-
optic crystal can vary according to the chan
ges of a
weak electric field.

4
. RedTacton
detects changes in the optical properties of an electro
-
optic crystal using a laser and converts the result to an
electrical signal in an optical receiver circuit.

Note that
RedTacton
transceivers which integrate
transmitters and receivers are also available.


MECHANISM OF COMMUNICATION WITH REDTACTON:
-

The transmitter sends data by inducing fluctuations in the minute electric field on the surface of the human body. Data is re
ceived
using a photonic electric field sensor that combines an electro
-
optic crystal and a laser light to detect fluctuations in th
e minute

electric field.




ABOUT HUMAN AREA NETWORK:
-

In addition to the WANs (Internet) and LANs, there are applications best served by Human Area Networks (HANs) that connect
the last meter.



Human society is entering an era of ubiquitous computing,

where everything is networked.

By making Human Area Networks feasible, Redtacton will enable ubiquitous services based on human
-
centered interactions and
therefore more intimate and easier for people to use.

THREE FEATURES OF REDTACTON:
-

Redtacton has th
ree main functional features.



APPLICATIONS:


ELIMINATION OF HUMAN ERROR



RedTacton
devices embedded medicine bottles transmit information on the medicines' attributes. If the user touches the wrong
medicine, an alarm will trigger on the terminal he

is carrying. The alarm sounds only if the user actually touches the medicine
bottle, reducing false alarms common with passive wireless ID tags, which can trigger simply by proximity.

MARKETING APPLICATIONS:
-

When a consumer stands in front of an advertisi
ng panel, advertising and information matching his or her attributes is
automatically displayed. By touching or standing in front of items they are interested in, consumers can get more in
-
depth
information.


Brochures only of products of interest to the
visitor can be downloaded automatically at trade shows. Inside a shop, shoppers can
view related information on their mobile terminals immediately after touching a product.

INTUTIVE OPERATION:
-

RedTacton

transceivers embedded in two terminals can communicate not only data

But also the control or configuration instructions needed to operate devices. Cable connections are eliminated. The body itse
lf is
used as transmission medium





Print out where you w
ant just by touching the desired printer with one hand and a PC

or digital camera with the other hand to make the link. Complicated configurations are reduced by downloading device drivers
"at
first touch”. Display notebook PC screen on projectors with jus
t a touch. Transfer songs to portable music players from notebook
PCs with just a touch

INSTANT PRIVATE DATA EXCHANGE:
-



o

By shaking hands, personal profile data can be exchanged between mobile terminals on the users. (Electronic exchange of
business
cards)

o

Communication can kept private authentication and encryption technologies

o

Group photos taken with digital cameras are instantly transferred to individual's mobile terminal.

o

Diagrams written on white boards during meetings are transferred to individ
ual's mobile terminals on the spot


PERSONALISATION:
-

Digital lifestyle can be instantly personalized with just a touch. A pre
-
recorded configuration script can be embedded in a mobile
terminal with built
-
in RedTacton transceiver.When another device with
R
edTacton

capabilities is touched, personalization data and
configuration scripts can be downloaded automatically.

PERSONALISATION OF AUTOMOBILES:
-



Just sitting in the seat triggers the car to load all its presents, just way you like



The seat position and

steering wheel height adjust to match the driver 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.



Touching the TV remote control triggers a filter/search routine
according to your personal programming preferences


APPLICATION FIELDS:
-

NEW BEHAVIOUR PATTERN

Various conductors and dielectrics can be used as
RedTacton

communication media, and this has the potential to create new
behavior patterns.



o

NTT redacton

device turns your body into swipe card


Japanese telecom company NTT is soon to launch a product that transmits data via your body, effectively turning you into a
touch
-
technology swipe card. RedTacton is a card
-
like gadget that you simply carry anywhere

on your person, and it transmits data
via electric fields&mdash a world's first according to NTT

CONFERENCING SYSTEM



An electrically conductive sheet is embedded in the table. A network connection is initiated simply by placing a lap
-
top on the
table
using different sheet patterns enables segmentation of the table into subnets. Walls and partitions can be used as
communication media, eliminating construction to install electrical wiring.

SECURITY APPLICATION:
-



Automatic user authentication and log
-
in w
ith just a touch.



ID and privileges are recorded in a mobile RedTacton device.



Corresponding
RedTacton

receivers are installed at security check points.



The system can provide authentication and record who touched the device.






USER VERIFICATIONS AND LO
CK MANAGEMENT AT

ENTRANCES:
-





Carrying a mobile
RedTacton
-
capable device in one's pocket, ID is verified and the door unlocked when the user holds
the doorknob normally.



Secure lock administration is possible by combining personal verification tools suc
h as fingerprint ID or other biometric
in the mobile terminal



Automated car door lock/unlock just by touching the handle; unlocking a bicycle just by sitting on it. As a pass in
amusement facilities

ADVANTAGES



RedTacton

does not require the electrode to be in



direct contact with the skin.
