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

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
