Effects of interface design factors on affective responses and quality evaluations in mobile applications

Through this study we examined the effects of design factors, namely balance and originality on users' affective responses and subsequent quality evaluations. We effectively manipulated balance and originality to see how it independently and together affects two sub dimensions of emotions i.e. arousal and valance. After this we evaluated the impact of this affective response on pragmatic and hedonic quality perceptions. Experimental results confirmed a significant impact of design factors on emotions and quality perceptions. Usability studies can have a better understanding of how design influences user decision-making. It breaks the efficiency perspective further which has heavily shadowed human computer studies and suggests that affect is equally if not more important when it comes to having desired user reactions from app design.
