In this study we look at user judgments like perceived quality and also visual appeal from an emotional perspective. This is important to examine since unlike existing studies that focus on the cognitive mechanism of first impression judgments, we use aesthetics framework forwarded by Lavie and Tractinsky, and Russells' circumplex model of emotions to examine the phe- nomenon. We also try to answer whether aesthetics lead to significant affective responses from users, which then trickle into quality perceptions and visual appeal, which are otherwise considered higher order judgments. Measurement of emotions has mostly been done through subjective evaluation e.g. self-report or survey. We use objective data (electro-dermal activity for arousal and facial electromyography for valence) in addition to subjective data to measure emo- tions. We design custom mobile app interfaces which users get exposed to achieve effective aesthetic manipulation.
