3. INTRODUCTION

4. INTRODUCTION
Wearables are an important and a new emerging
technology
Number of applications designed for wearables are
increasing rapidly
It is an extension of the user’s mind and body and
provides a hands-free environment
Will become commonplace in the near future and will be
embraced

5. 1.WHAT ARE WEARABLES?

6. WHAT ARE WEARABLES?
Scaled down electronic gadgets
Clothing or accessories run by a computer
Incorporate practical functions and features
Wearable computing: The study or practice of creating,
outlining, building, or utilizing small body-borne
computational gadgets
Examples: Smart watches, Smart Bands, Smart Jewelry and
glasses

11. 4) WORKING OF WEARABLES

12. At grass root level , wearables qualify as devices that are :
The working principles
of any and all wearables

13. How does it all work ?
● Two - Part device with feedback from another computer
● Presence of a variety of on-board sensors like :
○ Accelerometer , Gyroscope , Barometer , Ambient
light sensor , compass etc
● This array of sensors log various life activities like sleep
patterns , jogging activity .
● The use of highly mobile and efficient platforms.
● Persistent connection to information sources .
● Use cases specific to the ultra-portable omnipresent
nature of wearables enable them to work in a unique way.
● Putting it all together in a way no other technology gets
close to the user.

14. Android Wear

15. Android Wear - Structure
RUNTIMES
ART
DALVIK
Application
Framework
● Android wear is based on the Android Platform maintained by Google as the AOSP
● Kernel based on linux. (Open Source)
● Used the Dalvik runtime but since recently has moved to ART .
● An application framework that revolves around various managers which help apps
manage various resources.
● Applications can be developed using XML and Java using the SDKs provided.

16. Android Wear - Device and Development
● All Android devices use low power SOCs based on the ARM architecture , like the Qualcomm®
Snapdragon™ 400 clocked at 1.2GHz or Intel’s equivalent low power SOCs.
● They include a variety of on board sensors .
● Screens typically used enhance visibility in outdoor environment and consume lesser power .
Technologies like IPS LCDs , POLED , AMOLED .
● Android Wear apps are developed using the Android Wear API
○ It supports two way interaction between mobile and the wearable.
○ Uses the Bluetooth 4.0 LE when available .
○ Supports NLP and Voice Interactions along with touch gestures.
○ It is included the the APK developed for the Mobile module which makes it very portable
and convenient.
○ In true spirit of Android , its watch faces and other functionalities are highly customizable.

18. CONCLUSION
Wearables will effectively increase safety,
comfort and security for users
It will enhance the quality of life of the user
at both work and home
They are the true extension of mind and
body
