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

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

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

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

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

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

End Product

Schedules

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

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

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

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

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

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
