  1. D-Tech Reminder System Presented by goldFish Technologies

  2. Outline • Introduction • System • Target Market • Budget and Timeline • Team Dynamics • Additional Features • Future Prospects • What We Learned • Conclusion and Questions

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

  4. 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

  5. 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

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

  7. 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

  8. 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

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

  10. 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

  11. 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

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

  13. 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 10cm

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

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

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

  17. 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

  18. 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

  19. 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

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