    This paper describes the use of facial EMG to provide a continuous measure of the user's emotional state. Facial EMG was recorded while female users performed five tasks to one of two web sites. Frustration index scores were developed from the corrugator EMG data by calculating a percentage score of a pre-task baseline. As predicted, the frustration index was greater for (1) novices as compared to experienced users, (2) incorrect as compared to correct answered tasks, and (3) for the web site that was rated more difficult. The frustration index was able to provide important information on web page performance.
