Effects of Display Size and Type of Input on Cognitive and Emotional Response to Screen Tasks

Display size and type of input affect individual psychological responses to screen displays. The effects of display size and input type were measured in two experiments where the contents of stimuli led to either cognitive processing or emotional response; we included a psychophysiological dependent measure (skin conductance). As expected, touch contributed to increased emotional response of users. Computer-mouse input was associated with better performance. An effect of screen size was found for the cognitive task, but not for emotional response. The present findings suggest that display size and type of input is significant to user experience. Furthermore, it shows that selection of the appropriate device can vary depending on stimulus contents. Theoretical and social implications of these findings are discussed.
