Human Area Networking technology .

Uses the minute electric field emitted on the surface of the human body.

Japanese company Nippon Telegraph and Telephone Corporation (NTT).

combined touch and action to coin the term TACTON, and then added theword RED- a warm color- to emphasize warm and cordial communications.


3/29

A transmission path is formed at the moment a part of the human

body comes in contact with a RedTacton transceiver.

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.

A transceiveris a device that has both a transmitterand a receiverwhich arecombined and share common circuitry or a single housing. Similar devices

include transponders, transverters, and repeaters.

RED TACTON TRANSCEIVER


5/29

RedTacton transmitter induces a weak electric field on the surface ofthe body.

RedTacton detects changes in the optical properties of an electro-opticcrystal using a laser and converts the result to an electrical signal in aoptical receiver.

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


16/29

Print out where you want just bytouching the desired printer with one

hand and a PC or digital camera with theother hand to make the link.

Complicated configurations arereduced by downloading device drivers"at first touch".

Display notebook PC screen on projectors with just a touch

Transfer songs to portable music players from notebook PCs with just atouch.


17/29

By shaking hands, personal profile datacan be exchanged between mobile terminalson the users. (Electronic exchange ofbusiness cards)

Communication can be kept privateusing authentication and encryptiontechnologies.

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

Diagrams written on white boards during meetings are transferred toindividual's mobile terminals on the spot.


18/29

Your own phone number is allocated and billing commences.

Automatic importing of personal address book and callhistory.


19/29

The seat position and steering wheel heightadjust to match the driver just by sitting in thecar.

The driver's home is set as the destinationin the car navigation system.

The stereo plays the driver's favorite song.

Touching the TV remote control triggers a filter/search routineaccording to your personal programming preferences.


20/29

Various conductors and dielectrics can be used as RedTactoncommunication media, and this has the potential to create new behaviorpatterns.

An electrically conductive sheet is embedded in the table.

A network connection is initiated simply by placing a lap-top on the table.


21/29

RedTacton can carry music or video betweenheadsets, mobile devices, mobilephones, etc.

Users can listen to music from a RedTactonplayer simply by putting on a headset or holdinga viewer.


22/29

Carrying a mobile RedTacton-capable device inone's pocket, ID is verified and the door unlockedwhen the user holds the doorknob normally.

Secure lock administration is possible bycombining personal verification tools such asfingerprint ID or other biometric in the mobileterminal.

Automated car door lock/unlock just by touching the handle; unlocking abicycle just by sitting on it.

As a pass in amusement facilities.


23/29

A RedTacton receiver in a cabinet whereimportant documents are stored enables lockadministration and keeps a record of who

accessed documents at what time.

Seat reservation management by verifying that the right person is in the rightseat Log and verification of the person who touched the terminal.

RedTacton does not require the electrode be in direct contact with theskin. High-speed communication is possible between two arbitrary pointson the body.

With the electric amperage method, a clear signal line and ground line arerequired. With the electric voltage method, capacity coupling cansubstitute. Therefore, the electrode does not have to be in direct contactwith the skin.

uses the electric field that occurs naturally on the surface of the human body

for communication.

Electrons already present inside the body to move, creating a minutedisplacement current.

CONCLUSION:

Several "human body communication" technologies using the human

body as a transmission medium have been reported in the past. How ever

RedTacton employs a proprietary electric field/photonics method, whichsurpasses the other methods in terms of communication distance,

transfer speed, and interactivity.
