Red Tacton is a Human Area Network technology that uses the surface

of the human body as a safe high speed network transmission path. The technology is

called TACTON because this influences communication, that starts by touching

(Touch) leading to various actions (ACTON). RED is used to convey the meaning of

warmth in communication.

Red Tacton takes a different technical approach. Instead of relying on

electromagnetic waves or light waves to carry data, a Red Tacton transmitter couples

with extremely weak electric fields on the surface of the body. The weak electric

fields pass through the body to a Red Tacton receiver, where the weak electric field

affects the optical properties of an electro-optic crystal physically separating ends the

contact and thus closes the communication. Communication is possible using any

body surfaces such as hands, fingers, arms, feet, face, legs etc.,

The Red Tacton chips will be embedded in machines and contain a

transmitter and receiver built to send and accept any form of data stored in a digital

format. The chip then takes any type of filesuch as an MP3 music file or email

and converts it into digital pulses that can be passed and read through a human beings

electric field. The chip in the receiving device reads these tiny changes and converts

the file back into its original form.

Several human body communication technologies using the human

body as a transmission medium have been reported in the past. But Red Tacton

employs a proprietary electric field/photonics method, which surpasses the other

methods in terms of communication distance, transfer speed, and interactivity back

into its original form.

Working principle:

4/15

Using a new super-sensitive photonic electric field sensor, Red Tacton

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

mbps.

1. The Red Tacton transmitter induces a weak electric field on the surface of the

body.

2. The Red Tacton receiver senses changes in the weak electric field on the

surface of the body caused by the transmitter.

3. 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.

4. Red Tacton detects changes in the optical properties of an electro-optic crystal

using a LASER and converts the result to an electrical signal in a optical

receiver circuit.

It is to be noted that Red Tacton transceivers which integrate

transmitters and receivers are also available. The physical layer enables half-duplex

communication (transmission and reception are done alternatively) using a proprietary

CSMA/CD protocol. As with Ethernet cards, each transceiver card has a unique MAC

address. The upper layer above this is compliant with standard TCP/IP protocols.

Mechanism of communication:

The transmitter sends data by inducing fluctuations in the minute

electric field on the surface of the human body. The surface of the human body loses

some field due to the electric field returning to ground and electric field dissipated to

the earth from the legs. 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. This sensor measures faint electric fields by using a LASER

beam to detect fluctuations in the optical properties of an electro-optic crystal that are

caused by peripheral electric fields.

The illustration is as shown in the figure. It clearly depicts various paths of the field.

The crackling sensation one feels when shocked by static electricity is

caused by an electric current of several dozen milli-amperes suddenly flowing into the

body from the outside. The RedTacton electrode is covered with an insulating

material, no current flows into the body from the Red Tacton transceiver. As a result,

there is no shock caused by the inflow of electric current from the outside. However,

5

as in mobile phones, a weak induction current is created in the body owing to the

minute electric field created near the body when the movement occurs. This induction

current is very weak and similar to those occurring in everyday life. The size of the

induction current emitted on the body with Red Tacton is in conformity with the

Radio Frequency-Exposure Protection Standard established by the

Association of Radio Industries and Businesses (ARIB).

Red Tacton uses the human body as a path for the electric signals that

are communicated to represent data. The transmitter worn on a body uses the bodys

electrical field to transmit digital messages. For example, by shaking hands two

people can exchange business cards. When a user touches a do or handle, the system

realizes who the person is and gives the authorization. By holding a camera in one

hand and touching the printer with the other the photographs can be printed. By

touching a mobile phone the address book can be downloaded.

The signal waveform observed on the body is as shown in the figure. How ever a

distinction between a electric sensor and a photonic electric field sensor is also

illustrated. Photonic electric field sensors used in Red Tacton can measure stand-alone

contacts without being influenced by grounds. As a result, the received waveform is

not distorted, regardless of the receiver location. This makes long-distance and high-

speed body surface transmission possible.

Feature of red tacton:

Red Tacton has three main functional features. They are touch, broadband &

interactivity, any media

1. 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. 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.

2.Broadband & Interactive:

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

instantly and execute programs can be sent.

Communication speed can deteriorate

in crowded spaces due to a lack of

bandwidth

3.Any medium:

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.

DI ELETRICS CONDUCTORS

(Signals pass through materials) (Signals travel along surface)

A communication environment can be created easily and at low-

cost by using items close at hand, such as desks, walls, and metal objects. But there is

one limitation on the length of the conductor to be propagated, on installation

locations, and on the thickness of the dielectric to be passed through.

System safety:

No current flowing into the human body from RedTacton devices.

Red Tacton uses the electric field that occurs naturally on the surface

of the human body for communication. Transmitter and receiver electrodes are

covered with insulating films. No current flows into body from the Red Tacton

transceiver.

Displacement current occurring in the body is small enough.

There is no current flowing from the Red Tacton transceiver;

however, the body indirectly receives a minute electric field. This causes

electrons already present inside the body to move, creating a minute

displacement current. This displacement current is similar to those occurring in

everyday life.

RedTacton conforms to the safety guideline of induced current.

RedTacton is in conformity to the Radio frequency-exposure

Protection RCR standard (RCR STD-38) issued by the Association of Radio

Industries and Businesses (ARIB).

Application fields:

Red tacton devices embedded medicine bottles transmit information on

the medicines' attributes. If the user touches the wrong medicine, an alarm will triggeron the terminal he is carrying. The alarm sounds only if the user actually touches the

9

medicine bottle, reducing false alarms common with passive wireless ID tags, which

can trigger simply by proximity.

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.

By shaking hands, personal profile data can be exchanged between

mobile terminals on the users. (Electronic exchange of business cards)

Communication can be kept private using authentication and encryption technologies

Your own phone number is allocated and billing commences . Automatic

importing of personal address book and call history.

The seat position and steering wheel height adjust to match the driver

just 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

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.

Red Tacton can carry music or video between headsets,

mobile devices, mobile phones, etc. Users can listen to music from a Red Tacton

player simply by putting on a headset or holding a viewer.

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 such as fingerprint ID or other biometric in the mobile terminal.
