Emotions influence our cognition and could be a key for improving user experience. The measurement of these can be done in different ways. This projects explores the possibilities to measure emotions via mouse movements.

Different methods for emotion measurement have been developed, subjective and objective measures alike. The methods which are highly developed need user cooperation and impede the workflow and can therefore not be used continuously. The newer, less experienced methods have the problem of not "feeling" the user and are therefore not so reliable. This study shows a new way of emotion measurement via the user's mouse motions combining the advantages of the other methods by being directly connected but not intrusive. To prove this new concept, a set of software tools for measurement was written and an experiment for validation was planned, implemented and executed. The results of these experiments show that it is possible to use the computer mouse as a sensor for emotional states. Mouse movement speed values were statistically significantly different for high and low levels of arousal.
