Introduction

Human Area network

An emerging field ofcommunicationstechnology with thepotential to offersignificant advantages toPervasive computing.(military operations, smarthome etc).

Overview of Technology (1/2)

Is the idea of Pervasive computing really old?

Mark Weiser, 1952-1999

Father and founder of

ubiquitous computing.

-1988Ubiquitouscomputing -era

that replaces PCs with

invincible computersembedded into everyday

objects.

Overview of Technology (2/2)

Pervasive Computing Network Technologies: WPAN

Wi-Fi - [ IEEE 802.11 ].

Bluetooth - [ IEEE 802.15.1 ].

ZigBee - [ IEEE 802.15.4 ].

and other RF technologies.

Human Area Networks as a New,

Adaptive Computing Realm(1/3)

WAN and MAN :: fundamental components enabling

global interconnectivity.

The most frequent impacts to an individual are realized in

those regions proximate to him.

Human Area Networks (HAN), exists within the Personal

Area Network (PAN) bubble.

Human Area Network

Its a new technologywhich uses human bodyas transmission media.

It gives us safe and highspeed network

transmission.

Uses weak electric fields

on the surface of thebody as a transmissionmedium.

RedTacton (1/2)

It leverages the conductiveproperties of the human body to

transfer data among electronic

devices.

Conceived and patented in the

mid-1990s by Neil Gershenfeldand Thomas G. Zimmerman at the

MIT Media Lab.

RedTacton (2/2)

Uses the minute electricfield emitted on thesurface of the human

body.Technically, it is completely

distinct from wireless andinfrared.

It is a new HAN technology that uses the surfaceof the human body as a safe, high speed network

transmission path.

How it Works(2/3)

8/6/2019 Human Area Network Redtacton

16/26

How it Works(3/3)

The RedTacton transmitter induces a weak

electric field on the surface of the body.

The electric field sensor (transistor or photonic

electric field sensor) detects electric field that

reaches the RedTacton receiver.

Signals are processed in the receiver circuit

and the data is downloaded.

Application ofHAN (1/2)

One-to-one services : Marketing Application(Context awareness)

Touch advertising & receive detailed information

Inside a shop, shoppers can view related

information on their mobile terminalsimmediately after touching a product.

And since data can pass from one body toanother, you could also exchange electronic

business cards by shaking hands

Intuitive Operations : private data exchange

Conclusion

Unlike wireless, interception is difficult and security canbe considered to be high with RedTacton

When we compare this with other technology present

today it can give a better performance over others

It conforms to the Radio Frequency-Exposure

protection Standard (RCR STD-38) issued by the

Association of Radio Industries and Business (ARIB)

Still undergoing development: doesnt work reliably yet.

(common with emergence of new technology)

Supports the vision & future of pervasive computing
