7. Mobile Computing Systems
A portable electronic device along with its communication infrastructure, that enables computation and wireless communication.

8. Smart *
“Smart” mobile systems contain a mobile OS that can run mobile Apps.

9. Smart+ *
“Smart” mobile systems often contain – a touch screen, built-in GPS receiver, sensors, in addition to what a standard computer has.
Example of phone sensors:
Accelerometer
Magnetometer
Gyroscope
Compass
Light
Proximity
Temperature
Pressure

12. Putting them together
We will learn how to develop a mobile system – consisting of sensors, mobile devices, and laptop computers who will talk to each other over BLE and WiFi, as appropriate!

13. Course Lecture Topics Android App Development
Android Source Building/Customization
Arduino Programming
Device Architecture
Mobile Networks
Remote Services
Some Research Papers

14. Two Example Systems Android Based System (MobiCOG)
Arduino Based System
(Typing Ring)

15. Android Example: MobiCOG
Automation of MiniCog – a paper based 3 minute dementia pre-screening test.

16. Video Demo – MobiCOG

17. Android Example: MobiCOG
Features:
Chain Codes
Symmetry
Classifier:
k-NN 1
Chain-Code = (0,2,0,3,1,1,3,0)
Symmetry = (80%, 70%)

18. Arduino Example: Typing Ring
A Wearable, portable, accessory that allows us to input text into computers of different forms.
Connects wirelessly as a standard Bluetooth Smart keyboard.
Works on surfaces such as – a table , a wall, or even your lap.
Over 98% accurate in detecting typed keys.
Yields a typing speed of up to 50 keys/min.
Yields up to 15,500 keys with full charge.
Weighs ~ 15 gm

19. Arduino Example: Typing Ring
Wearing It
The ring is worn in the middle finger.
Seeking 3-Letter Zones
As the user hovers his hand on a surface, 3- consecutive keys on a on-screen keyboard is highlighted.
Typing a Key
The User makes a typing gesture with one of three fingers and the corresponding key is typed in.
On-screen visual feedback
Typing with 3-fingers

21. Next Class: Lab 1
The goal is to make sure everyone is ready with their Android development environment.
Android Studio
Will upload the pdf:
Prelab: Android Studio Setup.
