Abstract :
In this paper we investigate how configuration and visualization parameters influence the quality of experience in a 3D interactive environment, more specifically in a motion parallax setup. In order to do so, we designed a dedicated testing room and conducted subjective experiments with a team of evaluators. The tests considered parameters such as different disparities, amount of parallax, monitor sizes and visualization angles. Factors such as visual comfort, sense of immersion and the 3D experience as a whole have been assessed. The users were also asked to execute a task in the 3D motion parallax environment assessing the difficulty to complete the task for different parameter configurations. Obtained results suggest that user experience in an immersive environment is not as critically influenced by configuration parameters such as disparity and amount of parallax as initially thought. They also indicate that a better understanding of how this experience is influenced still requires the design and conduction of more comprehensive testing procedures.
