` RED TACTON meaning:tacton: touch-act-on (action triggered by touching)red: symbol of warmth and love conveying the cordiality of interpersonal

communications

` R ed Tacton works on HAN. (Human area networking)` Communication between electronic wearable devices on human body and outside

environment critical-so human area networking essential

` R ed Tacton uses the surface of the human body as a safe, high speed networktransmission path.

` R ed Tacton uses the minute electric field emitted on the surface of the human body

for the data transfer.

` Technically its completely distinct to wireless and infrared.

` Communication possible through any part of the body.

` R ed Tacton works upon the principle that the optical properties of anelectro-optic crystal can vary according to the changes of a weakelectric field.

` 10 mbps transmission speed is achieved between any 2 points onthe transmission path in the body.

` Major components of device are a red tacton transmitter and areceiver( electro-optic crystal and laser)

` There are 2 basic methods:

1. E lectric current method2. E lectric field method( R ed Tacton)

` The naturally occurring electric field induced on the surface of thehuman body dissipates into the earth. Therefore, this electric fieldis exceptionally faint and unstable.

` Photonic electric field sensors are developed.` It is a sensor that bounces a laser beam off of a crystal (electro-

optic crystal) and measures the reflected beam. Oscillations in theelectric field surrounding the crystal affect the crystal, whichchanges the reflected light's polarization.

1. Should measure electric field from a devicewithout contacting it.

2. Ultrawide band measurement should bepossible

3. Should support one point measurementindependent of ground

` In addition to the WANs (Internet) and LANs, thereare applications best served by Human AreaNetworks (HANs) as well.

` Many human movements like touching, gripping, walking, steppingetc. can lock or unlock equipments or start or stop an equipment or can result in data transfer

` Communication starts when any body part or embedded systemgets in contact through various physical contacts according tohuman natural movements .

` B andwidth is not at all affected with the variations in thenumber of users and also not affected with the use of duplex operation.

` B ecause the transmission path is surface of the body, thespeed is not compensated in congested areas.

` In addition to the human body, various conductorsand dielectrics can be used as transmissionmedia. Conductors and dielectrics may also be

used in combination.

` Safety is obviously the primary concern before the implementationof this technique.

` The transmitting and receiving electrodes of the R ed Tactontransceiver are completely covered with insulating film.

` So the body of the person acting as the transmission medium iscompletely insulated.

` When communication occurs, displacement current is generated bythe electrons in the body because the body is subjected to minuteelectrical fields.

` R ed Tacton is an exciting new technology for Human Area Networking.

` For long term plans the size of the transceiver should be reduced.

` It supports personal devices like P D As and

notebooks.
