The head or the heart?
Gillian M. Wilson, Martina Angela Sasse · 2000
The number of multimedia applications is constantly increasing. Subjective methods are typically used to determine the level of media quality required in applications, yet recent findings have shown that these have limitations. This paper introduces an objective method for assessing media quality - measuring physiological indicators of stress. An experiment examining the impact of video frame rate is presented. With low frame rates, physiological measurements indicated that users were under strain, even though subjectively most reported no differences between low and high frame rates. We conclude that the evaluation of media quality should not be conducted using solely subjective methods.
