Although virtual reality is a field that attracts research interest over the past years, certain aspects of the virtual environments are often overlooked. For example, the importance of sound in virtual environments is recognized but it remains rather vague, since the relation between virtual world and physical world sounds is not studied in detail. In addition, kinesthetic parameters are also important, since the user movement can affect the overall experience. The present study focuses on human factors in conditions that the physical and the virtual world sounds are contradicting. Kinesthesis is also considered and combined with user vision and hearing. There were 2 experimental conditions, in one the users experienced three levels of sound-vision in a virtual world and no sound on the physical world, while they are walking on a smooth surface and in the second experimental condition, the same three levels of sound-vision were compared to different and contradicting sound in the physical world, while the user was walking on a plastic surface that produced sound. The results indicated there were a few differences between the two experimental conditions (mainly concerning distraction from the virtual environment and perceived usability). However, in most measures the two groups did not seem to be largely affected by the physical world and seemed to immerse in the virtual one. Future works will focus on a combination of different surfaces and natural sounds, in relation to the virtual world.
