Most notably, it is a device that is always
with the user, and into which the user can always enter commands and execute a
set of such entered commands, and in which the user can do so while walking
around or doing other activities. This transformation allows it to be worn
constantly, with the goal of becoming a seamless extension of body and mind,
equipped with various sensors which measure heart rate, respiration, footstep
rate etc., and can help in body maintenance.

DEFINATION OF A WEARABLE COMPUTERS

·      
Wearable computing facilitates a
new form of human-computer interaction comprising a small body-worn computer
that is always on and always ready and accessible.

·      
A wearable computer is a computer
that is engulfed into the personal space of a user, controlled by the user, and
has both operational and interact ional constancy                                                                                                                                                    
                                         

                  HISTORY ON WEARABLE COMPUTING

The concept of wearable computing was first brought forward by
Steve Mann, who, with his invention of the ‘Wear Comp’ in 1979 created a
pioneering effort in wearable computing. 
Although the effort was great, one of the major disadvantages was the
fact that it was nothing more than a miniature PC. Absence of lightweight,
rugged and fast processors and display devices was another drawback. The 1980s
brought forward the development of the consumer camcorder, miniature CRTs etc.
brought forward the development of the eyeglass mounted multimedia computer.
With the advent of the internet and wireless networking
technologies, wearable devices have developed
a great deal.

LITRATURE REVIEW:

Wearable computing facilitates a new form of human-computer interaction
comprising a small body-worn computer that is always on and always ready and accessible. In this regard, the new computational framework differs from that of
hand held devices, laptop computers and personal digital assistants (PDAs). The
“always ready” capability leads to a new form of synergy between human and
computer, characterized by long-term adaptation through constancy of
user-interface.

 

APPLICATIONS

There
are several aspects and affordances of wearable computing are applicable. They
are discussed in brief below

1.    
Smart eyeglasses: It would not
appreciably obstruct the wearer’s vision, or otherwise be encumbering.for
example, the wearer could be used to play in a competitive game
e.g.volleyball 

2.    
Smart cards and badges: Wear Cam
is a simple apparatus for effortless capture, display, processing and
transmission of visual Imagery.Since the apparatus is worn on an extended
period of time, one adapts to it, and it begins to function as a true extension
of body.

3.   
 Military application: The smart shirt was
being designed for soldiers in combat, so that medical personnel could find the
exact location of a bullet wound.

ADVANTAGES

DISADVANTAGES

1.   
Portability

Equipment
can be heavy

2.   
Hands-free use

Quick to access

3.   
Comfortable                         

Some Wearable Computers can consist of a lot of wiring.
 

4.   
Always on for the task it is
designed

Can cause irritation in heat

5.   
Quick to access
 

Side-Effects such as  
Headaches.

 

 

 

             CONCLUSION

Wearable Computers will
help in the development of a cyborg a system in which the camaraderie between a
human and machine becomes seamlessly simple. This will bring forward a new set
of technical, scientific and social needs which will have to be addressed as we
take the first step towards coexisting with wearable computers
