Vergleich zweier Methoden zur Einschätzung und Beurteilung von Angst beim Betrachten von digitalen Bildern

Bachelorarbeit von Birte Lindhorst 

For many people, the mere thought of participation in traffic makes their heart race and stomach reel. This form of anxiety disorder, for example induced by an accident as traumatic experience, is called posttraumatic stress disorder. The therapy typically involves systematic exposure to feared places, objects and situations. Due to the fact that the inhibition level is lower, virtual reality exposure helps to ensure a systematic, exactly controlled and patient-adjusted increasing variation of feared stimuli. A serious game is a motivating context for a virtual reality exposure.

It is important for the therapist in charge to control and take stock of the client's feelings during interaction with the serious game. Additionally, it is gainful to know about the users' emotions during interaction with the technology while developing a serious game. A method is required, which enables a continuous data collection. The assessment of physiological feedback allows a long-term measurement.

This thesis presents an experiment that examines the usability and comparability of a technique that applies fuzzy logic to model emotions using physiological signals. The experiment employs a self-monitoring technique as comparative method. Pictures, which are widely used in research on emotions, evoked emotions, especially fear. While presenting the stimuli, data was collected with both methods.
