"The application of true-to-life virtual environments connected to our high fidelity models is a strategic initiative of our company,"

Sykesville, MD – January 28, 2013 - GSE Systems, Inc. (NYSE MKT: GVP) today launched its 3Di-TouchWall™, an integrated software/hardware solution that provides a highly immersive simulation experience similar to a cave automatic virtual environment (CAVE) at a fraction of the cost.

The 3Di-TouchWall produces a 3D-enabled 87-inch HD projected image. In combination with the system's infrared head-motion tracking, stereo sound and DLP® stereoscopic 3D glasses, users can interact with virtual equipment (e.g., pumps, valves, gauges) and freely navigate through large virtual environments such as power plants. The infrared motion tracking assures that the user's point of view exactly matches their position in real-time. The resulting parallax increases the realism beyond what stereoscopic 3D glasses alone can provide.

The 3Di-TouchWall uses the ActivBoard® 587 multi-user surface manufactured by Promethean World PLC that allows users to operate hands-free, without holding a controller or other input device.

At the heart of the unit is GSE's Activ3Di™ system, connecting GSE's first-principles-based simulator data to the virtual training environments. It allows real-world physics data to drive the virtual scene in real time for an unparalleled level of realism and immersion. Activ3Di meets ANS 3.5 standards. It brings the value of simulator-based Control Room Operator Training into the engineering space for a wide range of activities such as job performance measures, plant walkthroughs, pre-job briefs and task-based training.

"The application of true-to-life virtual environments connected to our high fidelity models is a strategic initiative of our company," said Jim Eberle, Chief Executive Officer of GSE Systems. "The 3Di-TouchWall is just one example where we have listened to the training challenges of our customers in the energy and processing industries and provided a product to enable them to train faster, learn more and spend less."

GSE will be demonstrating the 3Di-TouchWall™ system at two upcoming events:

Powerplant Simulation Conference (PowerplantSim'13)
Renaissance Tampa International Plaza Hotel
Jan. 28 to Feb. 1

Conference on Nuclear Training and Education (CONTE 2013)
Hyatt Regency Jacksonville-Riverfront
Booth 28-29
Feb. 3 to 6
