Point clouds have recently emerged as a promising and practical solution to code 3D visual information for immersive applications. Among other challenges, objective and subjective quality assessments are still open problems for this type of visual data representation. In this paper, we investigate the impact of already proposed subjective evaluation methodologies in order to assess the visual quality of point clouds in different display environments (e.g. on a desktop versus an augmented reality head-mounted-display) creating different types of experiences to users. Advantages and drawbacks of the above visualization strategies are compared to each other based on a rigorous statistical analysis.
