Mobile Computing Systems Mobile Computing Systems A portable electronic device along with its communication infrastructure, that enables computation and wireless communication.
Smart * Smart * Smart mobile systems contain a mobile OS that can run mobile Apps.
Smart+ * 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: oAccelerometer oMagnetometer oGyroscope oCompass oLight oProximity oTemperature oPressure

Two Example Systems Two Example Systems Android Based System (MobiCOG) Arduino Based System (Typing Ring)
Android Example: Android Example: MobiCOG MobiCOG Automation of MiniCog a paper based 3 minute dementia pre-screening test.
Video Demo Video Demo MobiCOG MobiCOG https://www.youtube.com/watch?v=kk05dKghpCA
Android Example: Android Example: MobiCOG MobiCOG Features: oChain Codes oSymmetry Classifier: ok-NN 1 Chain-Code = (0,2,0,3,1,1,3,0) Symmetry = (80%, 70%) 17
Arduino Example: Typing Ring 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
Arduino Example: Typing Ring 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. On-screen visual feedback Typing a Key The User makes a typing gesture with one of three fingers and the corresponding key is typed in. Typing with 3-fingers
