Welcome to VizUS!

VizUS is a research lab in the computer science department at Utah State University. The lab is doing research on interactive 2D/3D visualization, visual analytics (visualization + ML/DL/AI), VR/AR/MR, and 3D User Interfaces. We design, develop and evaluate a variety of visualization and virtual environment systems using state-of-art visualization and data analysis techniques and technologies, to help humans communicate with data for sense-making and decision making. The lab is located in Old Main 406. The lab space permits conducting VR/AR studies involving body movement as well as complex interactive studies in the open area or the conference room.

Viz+VR Makerplace

The lab is also a Viz+VR makerplace for USU CS students to work on Visualization and VR related research projects.  if you want to use the VR/Vis hardware and the lab space for your research project, please contact Dr. Isaac Cho (isaac(dot)cho(at)
