Abstract
Current work describes two evaluations in two different locations investigating possible differences in the experience of quality of stereo 3DTV systems. Herein, the work presents the usage of the Open Profiling of Quality method. This method allows going beyond up to now considered distinctive features (e.g., glasses wear comfort, brightness…). During the first evaluation standardized display-settings were used for each tested system. In the second study all systems were tested with their provided factory settings. Other factors like test stimuli, play out technology, laboratory settings, and viewing position were strictly standardized. Additionally, influencing factors like spectacle frames and display design have been minimized by using same eyeglass frames (but different technology) and hiding the display chassis. The results of both evaluations show distinct influences of display technology on quality perception. This is affirmed by the quality describing attributes deriving from the open profiling of quality method beyond the quantitative quality rating. This influence has to be considered within subjective evaluation of quality in order to support test-retest reliability and user centered approaches on quality evaluation of stereo 3D visualization. Different quality perception of different display technologies was confirmed even under different TV settings.
