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
