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

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
