3.  A small portable computer that is designed to be
worn on the body during use.
 Computer Clothing comprises of a computer built
within an ordinary clothing.
 Computer Cloths are usually either integrated into
the user's clothing or can be attached to the body
through some other means, like a wristband.
 They may also be integrated into everyday objects
that are constantly worn on the body, like a wrist
watch or a hands-free cell phone.

4.  Computer Cloths 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.
 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.

5.  Equipped with various sensors which measure
heart rate, respiration, footstep rate
 Without interfering with the user’s everyday
tasks.
 The design of computer cloths is still a topic of
research & a variety of user interfaces are being
proposed.

6.  Computer Cloths were first introduced in the
1500's with the pocket watch.
 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 computer
cloths were being created.

8.  Some computer cloths use “keyers” (key switches
mounted to a grip) and trackballs as input device.
 Some 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
screen).

10. 1.Ring Sensors
Pulse oximetry sensor that allows one to
continuously monitor heart rate and
oxygen saturation in a totally unobtrusive way.
The device is shaped like a ring and
thus it can be worn for long periods of time.
The ring sensor is equipped with a low power
transceiver.

11. Working:-
Transmittal type has a powerful LED for transmitting
light across the finger.
The motion of the finger can be measure with an
optical sensor.
This motion detector can be used not only for
monitoring the presence of motion but also
for cancelling the noise.

12. Working:-
The noise-cancelling filter combines two sensor
signals, one is the main signal and the other is the
noise reference.
The ring has a microcomputer performing all the
device controls and low level signal processing.
The acquired waveforms sample and are transmitted
to a cellular phone and it accesses a website for data
storage and clinical diagnosis.

13. Working:-

14. Block Diagram of Ring Sensors:-

15. Applications:-
CATRASTOPHE DETECTION
· Wireless supervision of people during hazardous
operations
Eg: military,fire fighting.
· In an overcrowded emergency department.
CHRONIC MEDICAL CONDITION
· in cardiovascular desease for monitoring the hyper
tension.
· chronic surveillance of abnormal heart failure.

16. Advantages:-
Continuous monitoring.
Detection of transient phenomena.
Promote further diagnostic and therapeutic
measures.
Reducing hospitalization fee.
Disadvantages:-
Initial cost is high.
Limited number of physiological parameters are to
be monitored.

17. 2.Smart Shirt
Smart shirt was developed at Georgia tech
Smart shirt is also called Wearable Motherboard
It uses optical fibers to detect bullet wounds and
special sensors and interconnects to monitor the body
vital signs during combat condition.

18. Architecture
It is woven into a single –piece garment (an
undershirt) on a weaving machine to fit a 38-40” chest
The plastic optical fiber (POF) is spirally integrated
into the structure during the fabric production process
T-connectors used in clothing are attached to the
fibers that serve as a data bus to carry the information
from the sensors on the body

19. Architecture
The smart shirt can be laundered without any
damage to the sensors themselves.
A microphone has been attached to transmit the
weavers voice data to monitoring locations.
This controller in turn processes the signals and
transmit them wirelessly to desired locations (eg:
doctor’s office, hospital, battlefield)

20. Applications
 Combat casualty care.
 Medical monitoring.
 Sports/ Performance monitoring.
 Space experiments.
 Mission critical/ hazardous application.
 Fire- fighting.
 Wearable mobile information infrastructure.

21. Advantages
 Continuous monitoring.
Right Treatment at the right time at the right cost.
 Easy to wear and takeoff.
 Reducing the health care cost.
Disadvantages
Initial cost is high.
 Battery life is less.

22.  speech recognizer
 keyboard alternative including chording keyboards (few keys
keyboards)and special purpose keyboards
 mouse alternatives including trackballs, joysticks
 tab alternatives including buttons, dial
 eye trackers
 head trackers
 pen
 gesturing
 bar code reader
 video capture devices, microphones, GPS locators
 other exotic devices such as skin sensors

23. head mounted displays (HMDs)
flat panels, text to speech
tactile output
non speech auditory output
paper and olfactory output (scent)

28.  Years ago you would not have thought that you
could do somethings that you can do today as
computers are getting smaller and more
powerful they can be integrated into virtually
anything.
 Now you can class your mobile phone as a
mobile computer as that can be used take
photos, surf internet, and many other things.
 We believe that all electronic devices will be able
to communicate with each other. and recognize
who you are similar to minority report.

29.  The use of mobile and computer cloths as
actual “tools” on the construction site will
enable interaction with smart infrastructure
systems in the future
 It will help in Medical field by monitoring the
patients.
 It will be used in the bullet proof jackets in
Military field.
