Introduction

Human Area network

An emerging field of communications technology with the potential to offer significant advantages to Pervasive computing. (military operations, smart home etc).

Overview of Technology (1/2)

Is the idea of “Pervasive computing” really old?

Mark Weiser, 1952-1999

Father and founder of ubiquitous computing.

-1988Ubiquitous computing -“era that replaces PCs with invincible computers embedded 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 technology

which uses human body as transmission media.

• It gives us safe and high speed network transmission.

• Uses weak electric fields on the surface of the body as a transmission medium.

Enabling Technology

RedTacton

RedTacton (1/2)

• It leverages the conductive properties of the human body to transfer data among electronic devices.

• Conceived and patented in the mid-1990s by Neil Gershenfeld and Thomas G. Zimmerman at the MIT Media Lab.

RedTacton (2/2)

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

Technically, it is completely distinct from wireless and infrared.

It is a new HAN technology that uses the surface of the human body as a safe, high speed network transmission path.

How it Works (1/3)

How it Works (2/3)

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 of HAN (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 terminals immediately after touching a product.

And since data can pass from one body to another, you could also exchange electronic business cards by shaking hands

•Intuitive Operations : private data exchange

Application of HAN (2/2) Personalization:

Security application

Comparing with other Network Technologies

Personal Digital Cellular

Wideband Code Division Multiple Access

Ultra Wideband

Personal Handy-phone System

Comparison with other network

Conclusion Unlike wireless, interception is difficult and security can

be 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: doesn’t work reliably yet. (common with emergence of new technology)

Supports the vision & future of pervasive computing
