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. Our Solution Design Requirements System Architecture Physical Design Budget Lessons Learned Acknowledgements Our Solution • 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. Project Design Requirements 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.
