A PRESENTATION ON REDTACTON

ABSTRACT:-

Imagine getting in a car and having it adjust its settings to the way you like them,

grabbing a door handle that knows if you are authorized to open it or shaking hands

with someone and invisibly exchanging electronic business cards. What if you could

walk into a room and connect to a network just by setting your laptop on a table? In

2020, whipping out your mobile phone to make a call will be quaintly pass. By then

phones will be printed directly on to wrists, or other parts of the body.

Who can imagine 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 other? Japans

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.

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 such as

touching, holding, sitting, walking, or stepping on a particular spot. Similar weak

electrical fields can be found around many objects, including those made from metals,

plastic, glass, ceramics and liquids, which mean they can also be part of a RedTacton

networks.

A person equipped with a sensor 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.

INTRODUC TION:-

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 human 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 according 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 super-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 changes 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 received using a photonic electric field sensor that

combines an electro-optic crystal and a laser light to detect fluctuations in the 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.


5/16

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 three main functional features.


6/16

TOUCH:-

Touching, gripping, sitting, walking, stepping and other human movements can be the

triggers for unlocking or locking, starting or stopping equipment, or obtaining data.


7/16

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

BROADBAND AND INTERACTIVE:-


8/16

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.Maximum communication speed may be 10 mbps depending on the usage

environment

Communication speed can deteriorate in crowded spaces due to a lack of bandwidth.

Device drivers can be downloaded instantly and executable programs can be quickly

sent. Taking advantage of this speed, device drivers can be downloaded instantly and

execute programs can be sent.

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*.

CONDUCTORS:-

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 advertising 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 itself is used as transmission medium

the door unlocked when the user holds the doorknob normally.

Secure lock administration is possible by combining personal verification tools

such 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

COMMUNICATION IN NEW DOMAIN:-

Potential for use as communication method in outer space and under water

Potential for use as communication method with devices inside the human body


15/16

RedTacton does not require the electrode be in direct contact with the skin. Highspeed

communication is possible between two arbitrary points on the body.

With the electric amperage method, a clear signal line and ground line are required.

With the electric voltage method, capacity coupling can substitute. Therefore, the

electrode does not have to be in direct contact with the skin.

On the other hand, photonic electric field sensors used in RedTacton can measure

stand-alone contacts without being influenced by grounds. As a result, the received


16/16

waveform is not distorted, regardless of the receiver location. This makes long-distance

and high-speed body surface transmission possible.

CONCLUSION:-

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. RedTacton is an exciting new technology for human area

networking. RedTacton system supporting two-way intrabody communication at a rate

of 10 Mbit/s between any two points on the body.
