The Department of Electrical and Computer Engineering (ECpE) contains two focuses. The focus on Electrical Engineering teaches students in the fields of control systems, electromagnetics and non-destructive evaluation, microelectronics, electric power & energy systems, and the like. The Computer Engineering focus teaches in the fields of software systems, embedded systems, networking, information security, computer architecture, etc.

The Department of Electrical Engineering was formed in 1909 from the division of the Department of Physics and Electrical Engineering. In 1985 its name changed to Department of Electrical Engineering and Computer Engineering. In 1995 it became the Department of Electrical and Computer Engineering.

Projection-based immersive virtual environments are very powerful tools to work on engineering and scientific problems involving teams of researchers. These environments enable the development of virtual representations of a problem domain in which multiple users can simultaneously share a virtual experience, providing a unique infrastructure for team work. The current limitation for effective teamwork is that these systems support only a single viewpoint, usually corresponding to a user wearing a head tracking device. This thesis presents a hardware and software design to enable multiple simultaneous viewpoints in a multi-screen immersive environment. This system is designed to be flexible and easily scalable, preparing for future expansion to additional users when the underlying technologies allow it. The design extends the commonly used single user time-multiplexed stereo viewing model to multiple users. This research also extends existing development tools to support our multiple viewer virtual design. This work also focuses on extending existing applications to multiple viewer environments. A design and implementation of the system is presented in detail. This system enables two users viewing stereoscopic images or four users viewing monoscopic images to simultaneously view the correct images projected on the screen from their tracked viewpoint.
