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
