3. INTRODUCTION
 A wearable computer is a small technological device capable of storing and
processing the data that can be worn on the body
 Wearable computer could be anything from a small wrist mounted system
to a bulky head mounted display .
 These are especially useful for applications that require for computational
support.

4. AIM OF WERABLE
COMPUTING
To develop new
interfaces that
mediate non –
computer activities
Without interfering
with the users
everyday task

5. HISTORY
 1991: Started the wearable computer at MIT.
 1995: worlds first convert wearable computer –camera and display
concealed in ordinary eyeglasses.
 1997: phD from MIT in this field he himself had invented.
 2010: works at university of Toronto.

6. EVALUTION

7. OPERATIONAL DETAILS
Software:
The commonly used operating system on a wearable
computer is the wos (wear comp os).
Redhat and gnu Linux can be run in close coordination as
operating system too.
 Hardware:
• Display
• Keyboard
• Hard drive

8. HOW WEARABLE COMPUTER
WORKS
 Some wearable computers use “keyers” and trackballs as input
device.
 Many try o use more intuitive means of input like gesture, speech
recognition and context awareness.
 The output may be presented through displays,lights,sound.

9. INTERACTION BETWEEN THE USER AND THE
COMPUTER
There are three operational modes of interaction between the
human and computer.
• constancy
• Augmentation
• mediation

10. CONSTANCY
The computer runs continuously, and is always ready to interact with
the user.
The signal flow from human to computer and computer to human,
runs continuously to provide a constant user-interface.

11. AUGMENTATION
 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.

12. MEDIATION
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

13. FEATURES
 Consistency:
There is always constant interaction between the computer
and the user and hence there is no need to turn the device on or off.
 Multi-tasking:
wearable computer provides computational support even
when the users hands, voice, eyes or attention is actively engaged with
the physical environment.
 Mobility:
These computers must go where the wearer goes. They are
always on and their wearer can access them anytime.

14. WEARABLE COMPUTER NETWORKING
GENERAL REQUIREMENTS
 Short-ranged
 Simple in design
 Low power consumption
 Security
 Self configuration
SECURITY REQUIREMENTS
• Privacy
• Data confidentiality
• Data integrity
• Availability
• Acess control

15. ADVANTAGES
 Portability
 Hands free use
 Comfortable
 Quick to access
 fashionable

16. DISADVANTAGES
 Equipment can be heavy
 Expensive
 Can cause irritation in heat
 Side effects such as heat
 Some wearable computer can consists lot of wiring

17. APPLICATIONS
• Augmented memory
• Face recognition
• Finger tracking
• Wearable computer in a wrist watch
• Wearable computer in shoe

18. WEARABLE COMPUTER DEVICES

19. CONCLUSION
• Whatever area wearable computer technology is applied to you can
see that it will improve the quality of life and make day –to- day life
less complicated.
