KNOWLEDGE ACQUISITION AND CYBER SICKNESS: A COMPARISON OF VR DEVICES IN VIRTUAL TOURS

Abstract

Virtual reality (VR) is a widely used platform for Product Lifecycle Management (PLM) support. Visualization of a virtual prototype in any phase of product or process design is important for making decisions about further development, testing and simulations. While the designers working on a particular product know its exact appearance, other personnel taking part in the development may need to use some advanced virtual reality devices, such as a Computer Aided Virtual Environment (CAVE), or a Head Mounted Display (HMD). The goal of the following study is to compare them and discuss their advantages and disadvantages while taking a tour in a reference model of a virtual plant. 45 students were exposed to a virtual model on a LCD monitor, HMD Oculus Rift, and a stereoscopic projection screen. We tested the rate of understanding the environment and possible cyber sickness symptoms.
