• A “Wearable Computer” is a computer that
could be worn on the body. Wearable
computers could be anything from a small
wrist mounted system to a bulky head
mounted display as shown below:
• Wearable computers are especially useful for
applications that require computational
support while the user's hands, voice, eyes,
arms or attention are actively engaged with the
To develop new interfaces that
mediate (augment, deliberately
diminish, or otherwise modify)
Without interfering with the user's
The design of wearable computers
is still a topic of research,
and a variety of user interfaces
are being proposed.

IT ALL STARTED FROM
After its invention, Wearable Computer have gone through 18 generations of
development, with research going on at prestigious institutions like MIT, Georgia
Tech and Carnegie Mellon University.

computer is the WOS (Wear Comp OS).
Redhat and GNU Linux can be run in close coordination
as an Operating System too.

• You hold up your left
hand, fingers pointing
to the right. The system
recognizes that you
want to make a call, and
projects a dialing pad
onto your fingers. You
tap the virtual keypad
with your right hand to
dial the call.
Some wearable computers use “keyers”
(keyswitches mounted to a grip, rather than
to a board, as with a keyboard) and
trackballs as input device.
Many try to use more intuitive means of
input like gesture, speech recognition or
The output may be presented through
displays, lights, sound.
There are three operational modes of interaction
between human and computer
Interaction Between The User
And The Computer
The computer runs continuously, and is always
ready to interact with the user.
Unlike a hand-held device, laptop computer, or
PDA, it does not need to be opened up and turned
on prior to use.
The signal flow from human to computer and
computer to human, runs continuously to provide a
Wearable computing is based on the notion that
computing is not the primary task.
The assumption of wearable computing is that the
user will be doing something else at the same time
as doing the computing.
Thus the computer should serve to augment the
intellect, or augment the senses.
Unlike hand held devices, laptop computers, and
PDAs, the wearable computer can encapsulate us.
It does not necessarily need to completely enclose
us, but the concept allows for a greater degree of
encapsulation than traditional portable computers.
Thanks to encapsulation, it can function as an
information filter, and allow us to block out
material we might not wish to experience,
Led by companies such as Xybernault,
HandyKey, and ViA. Forced alliances with
IBM and Sony in order to make wearable
computing widely available.
In 2001 IBM developed and publicly
displayed two prototypes for a wristwatch
computer running Linux, but the product
never came to market.
There is always a constant interaction between the computer
and the user and hence there is no need to turn the device
on or off.
Wearable computer provides computational support even
when the user’s hands, voice, eyes, or attention is actively
engaged with the physical environment.
Wearable computers must go where the wearer goes. They
are always on and their wearer can access them anytime.
• Simple in design
• Low power consumption
• Restricted to the user
• Data Confidentiality
• Data integrity
• Access Control
• Source Authentication
