Introduction goldFish Technologies Why goldFish? Known to be forgetful Our Goal Aid those who are forgetful Improve day to day organization

Our Motivation Forgetfulness is a common trait Inconvenience and frustration Wastes time Current Solutions PDA’s, Post-its, Applications Require user to input AND check Effective Reminders Message + Signal

Our Solution: D-Tech Integrates Current Functionality Calendar To-do List Item Detection Tagging and scanning items Smart comparison Automatic Reminding No manual checking Voice reminders

System Overview User Enters data Tags item System Detects User Scans user Compares Signals Displays

Central Unit: Database What is it? Dynamic data storage Back-up files for users Link-list structure Purpose Stores data during runtime Allow quick data retrieval

Central Unit: Database Software Programming Embedded MFC Embedded Visual C++ Windows CE Platform Data Synchronization Reading data from the online server Writing to back-up files

Central Unit: GUI Graphical User Interface Allows user interaction Simple and intuitive to use Tasks and Items Interaction View Add Edit Delete

Central Unit: GUI Other Functionality Allows adding of new users Audio feedback (voice alerts) Displays item images Time/date setting Additional Added Features Messaging feature Live weather updates

Central Unit: Physical System Embedded PC ARMV4I Processor MC9328 DragonBall Development Board Windows CE 4.2 OS Connection Wireless internet connection Physical Features Touch screen LCD Added sound system Custom enclosure

D-Tech Unit Purpose Activate scanning unit only if there is a user Features Motion detection range: 6m Components Passive Infrared Motion Sensor (PIR)

Scan Unit Components TRF7960 Evaluation Board from Texas Instruments UART to USB convertor RFID Reader Identifies user Send detected SmartTag IDs to Central Unit Capabilities Built-in antenna range: 10cm Detect up to 16 unique tags simultaneously

D-Tech and Scan Unit Physical Feature Custom enclosure LED light to signal activation

The “Wire” Temporary Work Around Complete transparent data connection Reason No USB host capability on embedded PC Convertor chips are expensive

Anywhere Access Form Web Application Online server Survey, questionnaire Purpose Alternative method of adding tasks and items Easily accessible

Anywhere Access Form Functionality Add tasks and items for any user Send messages Takes instant photos for items Security Features Requires user login File read / write protection

Anywhere Access Form Web Scripting Languages PHP: data storage to text files HTML: form layout design JavaScript: calendar Flash: webcam Application Used anywhere Used by anyone

Additional Features Weather Forecast Accurately report current weather conditions Linked to Yahoo weather forecast Message Feature Leave personal messages Added from Central Unit or internet

Target Market Busy Households Children Appointments Activities Senior Care Medication reminders Distant family Forgetful people Almost anyone (including ourselves!)
