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.

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

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




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.

Components of a
Wearable Computer:

Input devices: Speech acknowledgment may show up as the most suited info gadget, yet
may not be favored in a wide range of uses and situations, because of security
and execution issues. Signal Input gadgets are basic, smaller, and upgraded for
wearable utilize. These gadgets get contributions from the normal gestures.
Handwriting& Keyboard could be a standout amongst the most proficient info
gadgets, gave the information gadget isn’t too little or unbalanced. These
gadgets are simply worn on the hands or wrists and faculties he composing info
or penmanship. This does not have any links and conveys on infrared. Yield
gadgets: The yield gadget of a wearable PC could be either a head-mounted show
(HMD) unit with an earpiece or just the earpiece for a few applications. The
HMD works like a common screen, giving a picture skimming noticeable all around
before you. It utilizes LCD or TFT innovation. This permits expanded reality,
where virtual data covers this present reality.


Systems: There are two various types of systems in reference to a
wearable PC. One is to interface the gadget to the outer world and the other is
to interconnect the different parts, the later one being new for wearable PCs.
The main issue of interfacing with the WC to the outer world has a few options;
WAP, or Cellular Digital bundle information.

The second issue of interconnecting the different parts of the WC may
include both wired and remote associations. Peripherals like HMD and wrist/finger
worn devices may use standard wireless connections like Bluetooth.

There could also be a third type of communication, two wearable
computers talking to each other. Since you wear them you integrate the wiring
into normal clothing. It is wireless and comfortable. Here we also make use of
body network i.e., we send signals



are several aspects and affordances of wearable computing are applicable. In
fact, the fundamental use of wear comp may very well in personal empowerment of
the individual. Smart computing will allow us to explore all potential of many
modern technologies and ideas without wanting us to sacrifice freedom or privacy.
Instead of current vision of smart floors, smart light switches, smart
elevators, smart furniture and other smart technologies that watch us
correspond to our actions, what we will witness is the emergence of smart


numerous view wearcomps as a contraption. Indeed, the days when a wearcomp
client looked abnormal among the general public is finished. The dispatch of
cell phones was seen with bended eyebrows in numerous nations including India.
Be that as it may, in two years time, it has turned into a typical machine
among everybody. Similarly as a cell phone client gets adjusted to his handset,
and doesn’t feel any uneasiness in bearing it (he may have felt so first and
foremost), any wearcomp client will wind up a similar way. Secret frameworks,
in the 1990’s made the initial move toward making it conceivable to
look typical, and to be associated. The dispatch of Covert
(Wearcomp 7) is a noteworthy jump in the wearcomp innovation.




1.    Portability

can be heavy

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

Side-Effects such as   Headaches.



Wearable Computers will
help in the advancement of a cyborg a framework in which the brotherhood
between a human and machine turns out to be consistently basic. This will
present another arrangement of specialized, logical and social needs which
should be tended to as we venture out existing together with wearable PCs.
Broad innovative work at different focuses have guaranteed that these superb
gadgets will change our lives significantly sooner rather than later. A few
business sellers have begun assembling and showcasing these gadgets. . Instead
of living inside our very own data area, systems administration will expand our
extension through shared visual memory which empowers us to recollect something
we have never observed.
