  annote = {This paper reports on a study that investigates physiological responses to two levels of video quality (5 vs. 25 frames per second). Results show that a video quality of 5fps caused responses to indicate stress although only 16% of the users noticed the difference subjectively. Therefore, the authors propose a 3-tier approach to multimedia quality assessment that combines task performance, user satisfaction and user cost (in terms of stress). },
