Presentation Outline • Introductory Materials • Acknowledgement • Problem Statement • Operating Environment • Intended Users and Uses • Assumptions and Limitations • End Product and Other Deliverables • Project Activity Description • Accomplishments • Approaches Considered • Approach Used • Research Activities • Design Activities • Implementation Activities • Testing Activities • Resources and Schedules • Closing Materials

  3. List of Definitions • I2C – Inter-Integrated Circuit bus • IR – Infrared • RF – Radio Frequency • 802.11 – Wireless Ethernet • LCD – Liquid Crystal Display • Bluetooth – wireless technology

  4. Acknowledgements • Dr. Arun Somani • Dr. Zhao Zhang • Lockheed Martin

  5. Problem Statement • Develop a system that can be employed in places where a console PC or laptop PC cannot function effectively • The system shall not: • Hinder the user’s duties • Hinder the use of equipment currently in place

  6. Solution Approach • Instead of building a system into a chair: • Design peripherals that would enable a user to use a computer without the traditional methods • Research hardware that will perform the functions necessary for a personal computer • Integrate with software

  7. Operating Environments • Military support aircraft and warships • Confined spaces with large ambient noise • Forest Fires • Disaster Scenes

  8. Intended Users and Uses • Users: • Member of the United States Military • Avionic Pilots and Navigators • Emergency Workers • Uses: • Display terrain information • Display weather information • Standard PC functions

  9. Assumptions • Users will be familiar with Windows XP • User has full function of extremities • User’s vision is unimpaired

  10. Limitations • Project budget • Must not interfere with the user’s duties • System must not interfere with existing equipment

  11. End Product

  12. Deliverables • Project Plan • Weekly Reports • End Product Design • Peer Review Presentation • Project Poster • End Product Final Report • IRP Presentation • Client Report

  13. Project Activity Description • Accomplishments • Approaches Considered and One Used • Project Definition Activities • Research Activities • Design Activities • Implementation Activities • Testing and Modification

  14. Accomplishments • Integration of MicroGyro • Real-time Communication • Voltage Sensor • Temperature Sensor • Motion Sensors • Voice commands for system • Glasses display

  15. Accomplishments • Working demo of system • Performed for faculty advisors • Combined functionality of separate components • Macros created to perform necessary key functions • Streaming gyro data for mouse pointer

  16. Approaches Considered • Pointing Device • Trackball • Touchpad • Gyro sensor • Data Entry • Keyboard • Keypad • Voice recognition • Microphone • Bluetooth Headset • Traditional Microphone • Throat Microphone

  17. Approaches Considered • Mounting • Chair • Backpack • Distributed Wearable Components • Display • Goggles • Mini LCD Monitor • Wireless • Bluetooth • IR • RF • 802.11

  18. Approach Used • Mounting • Backpack • Display • Glasses • Wireless • 802.11 • Pointing Device • Gyro sensor • Data Entry • Voice recognition • Keypad • Microphone • Throat Microphone

  19. Research Activities • Experimented with: • Bluetooth • MicroGyro • I2C • Voice input technologies • Voice recognition technologies

  21. Implementation Activities • Modified EyeTop glasses for use with system • Designed data input methods • Glove • Keypad • Throat microphone • Modified software for full functionality • Voice recognition • Key remapping

  22. Testing and Modification • Experimented with microphone and voice recognition • Examined performance under many conditions • Compared results of different microphone models • Performed multiple iterations with glove/gyro • Monitored inputs and outputs • Strived to maintain processor efficiency • Combined with keypad to ensure functionality

  23. Closure Materials • Resources • Time • Fiscal • Schedules • Project Evaluation • Commercialization • Closing Summary

  24. Resources – Time

  25. Resources – Time

  26. Resources – Fiscal

  27. Schedules

  28. Project Evaluation • Design goals were achieved • To enable user to use computer without standard console • Team developed functional set of PC peripherals • Coordinated components for full capability • Many unforeseen events occurred • Loss of team member • Loss of budget • Loss of communications with client

  29. Commercialization • Proof of concept demonstration model • Could be commercialized with proper funding • Prototype ready for adoption

  30. Recommendations for Additional Work • Improve I2C MicroGyro device driver • Integrate I2C master controller / keypad / mouse clicks • Design a rugged integrated glove • Bluetooth wireless peripherals • Develop additional software applications

  31. Risk and Risk Management • Loss of funding • Loss of team member • Loss of equipment • Unclear requirements • Change of scope

  32. Lessons Learned • Need for greater coordination between client and design team • Ensure that skill sets are distributed evenly among members • Need firm requirements to prevent scope creep • Always have a contingency plan

  33. Closing Summary • Ambitious project • Numerous unforeseen events • Working prototype delivered to faculty advisor on time • Significant knowledge gained from use of components • Target-rich environment for future projects
