Advantages and Disadvantages
Wearable Technology is a portable computer that is included into
the space of a user, this can be worn anywhere around the body and
can be hands free use.
In this wearable computer differs from PDA’S (personal digital
assistant),which are designed for hand held use.
They may also be integrated into everyday objects that are
constantly worn on the body, like a wrist watch or a hands-free cell
Particularly it is a device that is always with the user, the user is able
to enter commands and execute a set of entered commands while the
user is walking around or doing any other activity.
Wearable Computers were first introduced by
Quing dynasty in the 1500's with the pocket watch.
In 1600’s Robert Dudley developed abacus ring for
In 1800’s watchmaker breguet developed a packet
watch on bracelet chain for Nepal queens
In 1967, Hubert Upton developed a technology
which allowed the person wearing the glasses to lip
read, this was using the LED device.
Even in the 1980's and the 1990's wearable
computers were being created.
History of wearable
Steve Mann’s wearable computer and reality mediator inventions.
To develop new interfaces that modify non-
Without interfering with the user’s everyday
The design of wearable computers is still a topic
of research & a variety of user interfaces are
AIM OF WEARABLE
Consistency: The signal flows from human to computer and
computer to human continuously to provide a constant user
Enhancement :The assumption of the wearable computing is that the
user will be doing something else along with computing. Thus, the
computer should serve to increment the intellect or augment the senses.
Mediation: acts as a mediator as it aids its users by providing its
umpteen applications in medical care
Privacy : Wearable computing can be used to create a new level of
Convenient :It is verry convenience to the user.
Unrestrictive :Wearable devices enable a person to do multi tasking .
Features of Wearable Computers
Some wearable computers use “keyers” (key
switches mounted to a grip, rather than to a board,
as with a keyboard) and trackballs as input device.
Many try to use more intangible means of input like
gesture, speech recognition or context awareness.
The output may be presented through displays,
lights, sound or even haptic interfaces(touch
Some mediated reality (ability to modified reality)
systems can also be considered wearable computers.

Architecture of Wearable computing
speech recognizer:- Speech recognition is used to identify words in
spoken language. Voice recognition is a biometric technology used to
identify a particular individual's voice.
keyboard alternative including chording keyboards (few keys
keyboards)and special purpose keyboards
mouse alternatives including trackballs, joysticks
tab alternatives including buttons, dial
eye trackers: eye tracking is the measurement of eye activity. Where do
we look? What do we ignore? When do we blink?
head trackers :Head tracking is used in many games to measure the
movement of your head in the real world
bar code reader
video capture devices, microphones, GPS locators
head mounted displays (HMDs)
flat panels, text to speech
non speech auditory output
paper and olfactory output (scent)
Wearable computing In Military field
The advantages of Wearable Computers are:-
- Enhanced Communication
- Work from anywhere
The disadvantages of Wearable Computers:-
- Equipment can be heavy, Expensive
- Some Wearable Computers can consist of a lot of wiring
- Can cause irritation in heat, Side-Effects such as Headaches
- It may become easier to get data on an individual if the item is
Advantages And Disadvantages
The use of mobile and wearable computers
as actual “tools” on the construction site will
enable interaction with smart infrastructure
systems in the future. But to reach this goal,
we face some challenges that have to be
