This thesis investigates the effect of emotional facial expressions of a virtual character on people&rsquo / s performance for interactive digital tasks. The basic and universal emotions are used in the study. Facial expressions of these emotions are created according to the Facial Action Coding System (FACS), which is a system that describes facial movements in the face. The patterns of cooccurences of Action Units (descriptions of facial movements defined in FACS) for basic emotions are also implemented into emotional facial expressions with regard to findings of the studies in the literature. A study was conducted to validate the recognition of emotion specific facial expressions that are built by Poser software. To investigate the effect of emotional facial expressions on people&rsquo / s performance for digital interactive tasks in a virtual environment, a digital interactive application created by Unity software was used in the final study of the thesis.
