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.

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,

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
(wireless LAN)
Device drivers can be downloaded
instantly and executable programs
can be quicklysent.(REDTACTON)

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

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
