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?
-1988
Mark Weiser, 1952-1999
Father and founder of
ubiquitous computing.
Ubiquitous computing -“era
that replaces PCs with
invincible computers
embedded into everyday
objects.”

Pervasive Computing Network Technologies: WPAN
•Wi-Fi - [ IEEE 802.11 ].
• Bluetooth - [ IEEE 802.15.1 ].
•ZigBee - [ IEEE 802.15.4 ].

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)
 It is a new HAN technology that uses the surface
of the human body as a safe, high speed network
transmission path.
Uses the minute electric
field emitted on the
surface of the human
body.
Technically, it is completely
distinct from wireless and
infrared.
How it Works (1/3)
How it Works (2/3)
How it Works (3/3)
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.

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.
•Intuitive Operations : private data exchange
 And since data can pass from one body to
another, you could also exchange electronic
business cards by shaking hands
Application of HAN (2/2)
Personalization:
 Security application
Comparing with other Network
Technologies
Wideband Code Division
Multiple Access
Personal Digital Cellular
Personal Handy-phone System
Ultra Wideband
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
