ABSTRACT Technology is making many things easier; I can say that our concept is standing example for that. So far we have seen LAN, MAN, WAN, INTERNET & many more but here is new concept of “ RED TACTON ” which makes the human body as a communication network by name…. HAN (Human Area Network). NTT lab from Japan is currently testing & developing this revolutionary technology. Red Tacton is a new Human Area networking technology that uses the surface of the human body as a safe, high-speed network transmission path.
Red Tacton uses the minute electric field generated by human body as medium for transmitting the data. The chips that will be embedded in various devices contain transmitter and receiver built to send and accept data in digital format. In this paper we will discuss about red tacton, and it’s working states, and applications of red tacton in various fields. And we will compare our red tacton with the other technology for data transmission. CONTENTS ? WHAT IS REDTACTON ? HOW REDTACTON WORKS ?

REFERENCES [pic] We may have imagined the feature as a place crawling with antennas and emitters, due to the huge growth of wireless communications. And it is seems that the current means of transferring data might already have a very serious competitor none other than the human body.
Thus NTT labs from Japan has announced that is currently testing a revolutionary technology called “ red tacton ”, which use the electric fields generated by the human body as medium for transmitting the data. The chips, which will embed in various devices, contain a transmitter and receiver built to send and 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 format that takes the form of digitals pulse that can be passed and read through a human being electric field . he chip in receiver devices reads these tiny changes and convert the file back into its original form. RedTacton is a new Human Area Networking technology that uses the surface of the human body as a safe, high-speed network transmission path RedTacton uses the minute electric field emitted on the surface of the human body. Technically, it is completely distinct from wireless and infrared. Why Named RedTacton? Because with this technology, communication starts by touching (Touch), leading to various actions (Act on) and the colour red to convey the meaning of warmth in communication.
Combining these phrases led to the name, “RedTacton”. A transmission path is formed at the moment a part of the human body comes in contact with a RedTacton transceiver. Physically separating ends the contact and thus ends communication. Using RedTacton, communication starts when terminals carried by the user or embedded in devices are linked in various combinations according to the user’s natural, physical movements. 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. [pic] RedTacton can achieve duplex communication over the human body at a maximum speed of 10 Mbps. [pic] 1. The RedTacton transmitter induces a weak electric field on the surface of the body. 2. The electric field sensor (transistor or photonic electric field sensor) detects electric field that reaches the RedTacton receiver. 3. Signals are processed in the receiver circuit and the data is downloaded. A Japanese company has discovered that the best cables may be your arms and legs.
According to NTT(NIPPON TELEGRAPH AND TELEPHONE CORPORATION) Laboratories, your whole body is the perfect conductor for electronic data, meaning that information such as music and films could be downloaded in seconds via your elbow. [pic] The transmitter sends data based on fluctuations in the weak electric field induced in the body. The electric field is received using super-sensitive electric field sensing technology. [pic] [pic] – The naturally occurring electric field induced on the surface of the human body dissipates into the earth. Therefore, this electric field is exceptionally faint and unstable. The super-sensitive electric field sensing technology measures the weak electric fields induced by the super-efficient alternating electric field induction technology developed by NTT. [pic] In addition to the WANs (Internet) and LANs, there are applications best served by Human Area Networks (HAN) that connect the last meter. [pic] Human society is entering an era of ubiquitous computing, where everything is networked. By making Human Area Networks feasible, RedTacton will enable ubiquitous services based on human-centered interactions and therefore more intimate and easier for people to use. pic] RedTacton has three main functional features. [pic] 1. Touching, gripping, sitting, walking, stepping and other human movements can be the triggers for unlocking or locking, starting or stopping equipment, or obtaining data. [pic] [pic] 2. 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. [pic] 3. 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 Touching, gripping, sitting, walking, stepping and other human movements can be the triggers for unlocking or locking, starting or stopping equipment, or obtaining data. The chart below shows the positioning of RedTacton with respect to existing communication technologies. The focus on ubiquitous service has brought about the shortening of distances in communication. RedTacton is positioned as the last 1m solution to ultimate close-range communication. Wireless communication creates connections when signals arrive, allowing for easy connections because connectors are unnecessary.
However, seen from another aspect, the arriving signals can be intercepted, so security becomes an issue. Wired communication transmits data between two connection points, so interception is difficult and security can be considered to be high. However, connectors and cables are a nuisance. Taking the above points in account, RedTacton is situated directly between wireless and wired communication. In other words, RedTacton allows for easy connection without connectors, while at the same time allowing transmission of data only between two contact points. It thus has the feature of being difficult to intercept. pic] (Wireless station that does not require license) RedTacton meets the standard for weak wireless station as set by Japanese telecommunication regulations [pic] Five major application fields using RedTacton are introduced. [pic] Enable one-to-one services tailored to the user’s situation and tastes. – Attribute information recorded in the RedTacton device is sent to the touched objects. – The appropriate service is provided based on the attribute information received by the RedTacton receiver. [pic] [pic] Natural movements and actions are the trigger. There’s no “operation” any more.
Just intuitive human interaction. – RedTacton transceivers embedded in two terminals can communicate not only data but also the control or configuration instructions needed to operate devices. – Cable connections are eliminated. The body itself is used as transmission medium. [pic] Digital lifestyle can be instantly personalized with just a touch. – A pre-recorded configuration script can be embedded in a mobile terminal with built-in RedTacton transceiver. – When another device with RedTacton capabilities is touched, personalization data and configuration scripts can be downloaded automatically. pic] Various conductors and dielectrics can be used as RedTacton communication media, and this has the potential to create new behavior patterns. [pic] [pic] [pic] Automatic user authentication and log-in with just a touch. – ID and privileges are recorded in a mobile RedTacton device. – Corresponding RedTacton receivers are installed at security check points. – The system can provide authentication and record who touched the device, and when.
