• Introduction to wearable computers
• Applications of wearable computer in various fields
• Features of wearable computer
• Advantages of wearable computer
• Disadvantages wearable computer

3. INTRODUCTION TO WEARABLE COMPUTER
• Wearable computers are small computing devices that people
wear on their body(usually close to skin).
• A Wearable computer is a digital device that is either strapped or
carried on a user’s body.
• It is a small technological device capable of storing and
processing data that can be worn on the body.
• Wearable computers are designed for accessibility and
convenience, by making information quickly and readily available
to the wearer.

4. INTRODUCTION TO WEARABLE COMPUTER
• Wearable computers can have specific uses, such as fitness trackers, or have a wide
array of features, such as a smartwatch with many “smart” functions similar to those
found on a smartphone.
• Apple Watch and Fitbit are classic examples of wearable technology, but those aren’t
the only devices being developed today.

5. FORMS AND SENSORS OF WEARABLES

6. APPLICATION OF WEARABLE COMPUTER IN VARIOUS
FIELDS
• Head mounted devices
• Health care applications
• Military applications
• Wearables in sports
• Google glass

7. HEAD MOUNTED DEVICES
Purpose of head mounted devices:
• Virtual reality
• Gaming

8. HEALTH CARE APPLICATIONS
• Wearable blood pressure monitor:
• This is an FDA-cleared medical device uses an inflatable
cuff inside the watchband that will activate when you
want to take your blood pressure.
• It syncs up to a companion app called HeartAdvisor,
which provides information about your readings.
• The app collects and stores your data in the form of
color-coded graphs.

9. HEALTH CARE APPLICATIONS
• Wearable ECG monitor:
• Detects heart rate and ECG anywhere, anytime without using
wires, patches or gels needed.
• It is wearable with the chest strap. Suitable for everyday use.
• Attach the device to the chest strap.
• Wear the strap directly with electrodes in contact with the
skin.
• Remove the strap ,heart rate detection will stop
automatically and the heart rate will be saved in the device
on the app called vihealth.

10. MILITARY APPLICATIONS
• The Multi-Domain Operations wearable can monitor soldiers in the
midst of battle, providing valuable medical data and other information in
real time.
• It was invented by next-flex, a California based research company.
• The soldier can wear it in their combat uniform and it is used to monitor
soldier stress, injuries, and signs of fatigue.
• It could also detect and classify battlefield blasts and explosions, sends
the information and alerting commanders even before soldiers make a
verbal report.
• It automatically keeps track of soldier's health status, medical history,
and ongoing conditions.

11. MILITARY APPLICATIONS
• Thin and Flexible Heaters in Military Clothing:
• It helps in staying warm in any weather condition by adding a printed heater to
gloves, pants, jackets, helmets, and boots.
• Printed heaters use silver and carbon conductive inks and it can be sown into almost
any kind of fabric.
• Printed heaters do not have any uncomfortable wiring.
• They are also self-regulating, so there is no need for any outside controls.
• This is a great feature because they will not overheat, spark or start any electrical
fires.
• By adding a printed heater to the military personnel’s clothing, they will be able to
withstand the temperature extremes within harsh climates.
• These heaters also distribute heat evenly.

12. WEARABLES IN SPORTS
• The first wearable device in sports was found in the year 2009, and it was used by European
soccer club to measure overall player workload during games.
• Each player’s biometric was monitored in real time to find signs of exhaustion or injury while on
field.
• GPS tracking devices are worn by athletes on the upper back, and is used to monitor changes in
athlete position over time.
• It was first used by Australian Institute of Sport in 2004 which collected data at a frequency of 5 Hz
, i.e, it collected 5 data points per second.
• Later devices like GPEXE Pro² by GPEXE was developed that collected data at a frequency of
18hz.

13. WEARABLES IN SPORTS
• Heart rate monitors:
• FirstBeat are leading the way in this area of wearable technology, measuring heart
rate variability.
• Smart garments are developed which have heart rate sensors (along with other
sensors as well)are integrated directly into the garments fibers.
• GPS companies such as Catapult have now integrated heart rate straps into their vests
which means that athletes only need to wear one accessory, not two.
• Heart rate sensors are easy to use and understand so they can be used in most sports.
• They offer valuable data from day one and the metrics are easy to understand.

14. GOOGLE GLASS
• It was announced in April 2012, and released in 2015.
• Google Glass is a spectacle based wearable computer that resides directly on your eyes.
• The Google glasses function as a hands-free smartphone.
• Voice search
• Ability to send texts, make voice and video calls.
• Captures and shares photos and videos through Google+
• Starts a Google Hangout
• Delivers search results, including the weather.
• Provides directions and help in navigation.

15. FEATURES OF WEARABLE COMPUTER
• Consistency: The computer runs continuously and is user friendly. Unlike, a
hand held devise like tablets or laptops, it does not need to be opened up and
turned on prior to its use. The signal flows from human to computer and
computer to human continuously to provide a constant user interface.
• Convenient: Because of its small size and light weight wearable technology is
very convenient to use.
• Unrestrictive: Wearable devices enable a person to do multi tasking and do
not restrict the focus of a person to one particular thing.

16. ADVANTAGES OF WEARABLE COMPUTER
• It can increase productivity.
• It helps people to maintain fitness.
• Hands free and portable, eliminating the need to take our devices out of our
pockets.
• It helps us to track our location with GPS, and view text messages more quickly.

17. DISADVANTAGES OF WEARABLE COMPUTER
• Wearable Tech is Expensive
• Wearable Tech is Limited
• Size and battery limitations prevail.
• Privacy issues

18. CONCLUSION
• Wearables have promising potential in various fields
• It can promote healthier lifestyle in the field of healthcare.
• Further efforts are needed until wearable technologies become more safeand
accessible.
