RED TACTON


2/40

Red Tacton is a new Human Area Networking technology thatuses the surface of the human body as a safe, high speednetwork transmission path.Red Tacton uses the minute electric field emitted on the surfaceof the human body. Technically, it is completely distinct from

wireless and infrared .A transmission path is formed at the moment a part of thehuman body comes in contact with a Red Tacton transceiver.Physically separating ends the contact and thus endscommunication Using Red Tacton, communication starts whenterminals carried by the user or embedded in devices are linkedin various combinations according to the user's Communicationis possible using any body surfaces, such as the hands, fingers,arms, feet, face, legs or torso.

Red Tacton works natural, physical movements.

HIS TORY

We may have imagined the feature as a place crawling withantennas and emitters, due to the huge growth of wirelesscommunications.And it is seems that the current Means of transferring data

might already have a very serious competitor none other thanthe human body.Thus NTT labs from Japan has announced that is currentlytesting a revolutionary technology called red tacton ,whichuse the electric fields generated by the human body as Mediumfor transmitting the data . The chips which will be embedded invarious devices contain a transmitter and receiver built to sendand accept data in digital format. The chips can take any type of file such as mp3 music file or mail and convert it in to the formatthat takes the form of digital pulse that can be passed and readthrough a human being electric field .

W H Y TH E NAME REDTACTON?

The name we chose for this technology is derived from touch-act-on meaning actiontriggered by touching combined with red, which in Japaneseculture is an auspicious color withconnotations of warmth and love, to convey the cordiality andwarmth of interpersonal

communications."Red" for warmth,"T" for touch, and

Acton" for action

CONTD...Using a new super-sensitive photonic electric field sensor, Red Tactoncan achieve duplex communication over the human body at a maximum

speed of 10 mbps The Red Tacton transmitter induces a weak electricfield on the surface of the body. The Red Tacton receiver senses changesin the weak electric field on the surface of the body caused by thetransmitter .Red tacton relies upon the principle that the opticalproperties of an electro-optic crystal can vary according to the changesof a weak electric field. Red Tacton detects changes in the opticalproperties of an electro-optic crystal using a laser and converts theresult to an electrical signal in a optical receiver circuit. The transmittersends data by inducing fluctuations in the minute electric field on thesurface of the human body. Data is received using a photonic electricfield sensor that combines an electro-optic crystal and a laser light todetect fluctuations in the minute electric field.

FEATURES

1 . TOUCH :Touching, gripping, sitting, walking, stepping and other human movements can be thetriggers 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 invariouscombinations through physical contact according to the human's natural movements.


13/40

2 .BROADBAND & INTERACTIV EDuplex, interactive communication is possible at a maximum speed of 10Mbps. Becausethe transmission path is on the surface of the body, transmission speed does not deteriorate

in congestedareas where many people are communicating at the same time .Taking advantage of thisspeed, devicedrivers can be downloaded instantly and execute programs can be sent.


14/40

3.ANY MEDIAIn addition to the human body, various conductors and dielectricscan be used as transmission media. Conductors and dielectrics may also be used incombination.

DI ELETRICS CONDUCTORS(Signals pass through materials) (Signals travel along surface)

A communication environment can be created easily and at low-cost byusing items close at hand, such as desks, walls, and metal objects. But there is one limitation onthe length of the conductor to be propagated, on installation locations, and on the thickness of the dielectric to be passed through.

ADVANTAGE OV ER BLUETOOTHThe system envisioned by NTT, utilizes a conversion method which takes digital data into a

stream of low-power digital pulses. These can be easily transmitted and read back through thehuman electric field.While it is true that similar personal area networks are already accessible by using radio-basedtechnologies like Wi-Fi or Bluetooth, this new wireless technology claims to be able to send dataover the human skin surface at transfer speeds of up to 10Mbps, or better than a broadband T1connection. Receiving data in such a system is more complicated because the strength of the

pulses sent through the electric field is so low.Red Tacton solves this issue by utilizing a technique called electric field photonics : A laser ispassed though an electro-optic crystal, which deflects light differently according to thestrength of the field across it. These deflections are measured and converted back intoelectrical signals to retrieve the transmitted data.According to Tom Zimmerman, inventor of the IBM personal networking system, body-basednetworking 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 thedevice you are trying to connect to. But in a busy place there could be hundreds of Bluetoothdevices within range.Moreover, body-based networking seems to allow for more natural interchanges of informationbetween humans, as only when you are in true proximity you can make this system work. Thereare some specific applications that would appear as being ideal matches for Red Tacton-liketechnologies.

Syste m sa fety:No current flow ing int o the bod y fr om re d tact on devices:

RedTacton uses the electric field that occurs naturally on thesurface of thehuman body for communication. Transmitter and receiver electrodes are covered with aninsulating films. No current flows into the body from theRedTacton transceiver.Disp lacem ent current occuring in the bod y is sma ll en oug h :

There is no current flowing from the RedTacton transceiver;however, the

body indirectly receives a minute electric field. This causeselectrons already presentinside the body to move, creating a minute displacement current.This displacementcurrent is similar to those occurring in everyday life.
