19. Putting them together
A mobile system often consists of sensors, mobile phones, and a server who talk to each other over BLE and WiFi, as appropriate.

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

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

22. Video Demo – MobiCOG

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

24. 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

25. 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

27. Next Class Download and install Java and Android Studio.
Read the “Class Work 1” ahead of time.
Bring your laptop, your Android device and the USB cable.
After a brief lecture (Android Studio), we will complete class work 1 together.
