Project Goal:To create a three dimensional environment simulation headgear.
Arnold Aquino, Dan Ziegler, Walter Schnoor, Dan Bosscher
Problem Statement• There exists a need to simulate
environments that are not feasible, safe, or otherwise realizable.
• An environment simulator could be used for anything from flight training to hazardous material cleanup training to architectural walkthroughs.
Project Motivation• An environment simulator would require the fusion
of several electrical engineering fields.
• Immersive environment simulators can cost several thousand dollars; this project was motivated by a desire to bring the technology to a wider customer base in numerous fields.
• Virtual reality simulation is a field that is growing as technology grows. Recent advancements in technology have made a low-cost simulator possible.

Lessons LearnedAcknowledgements
• To simulate unrealistic or dangerous situations, Team 3 designed SimEscape, a 3D environment simulation headgear.
• SimEscape was designed to be a safe place for learning, visualizing, and designing.
Our Solution
I. SimEscape will be worn on the user’s head.
II. It will allow the user to visualize a computer generated environment in three dimensions.
III. It will track the motion of the user’s head, allowing the viewing angle to be updated by a simple turn of the head.
