The present study investigated the effect of emotional feedbacks in human-computer interaction. By using ‘task-frustration-feedback modeling’, proper emotional feedbacks were explored by levels of task difficulty. In experiment 1, number ordering task which is easy and simple was used. Participants experienced frustration induced by mouse delay during their task. The difficult task given in the experiment 2 was information searching using texts with hyperlinks, and frustration was induced by loading time delay. Through the two experiments, different in levels of difficulty, no effect of affective feedbaks on task performances was found. However, from a self-reporting survey, emotional feedbacks designed to reduce users’ negative emotion have been found effective.
