Virtual reality technologies provide a unique method for enhancinguser visualization of complex three-dimensional objects andenvironments. By experience and environmental interaction, users canmore readily perceive the dimensional relationships of objects typicallyportrayed via static multiview or pictorial representations. Untilrecently, many of the VR technologies required significant computingpower for adequate delivery and provided realism that is often less thanactual. Alternatively video-based VR technologies overcome the two majorlimitations of true three-dimensional VR technologies-computinghorsepower and realism. The focus of this contribution is to providebackground information on VR technology for the improvement of spatialabilities, describe the advantages of video-based VR technologies, andprovide examples showing how video-based VR can be used to enhancevisualization in education and training
