How do visual angle and physical screen size affect presence and emotional responses of game players?

This study examines specifically the effects of these two properties of large displays on presence and emotional responses, using physiological as well as subjective methods. The results indicate that the larger visual angle offered by a large display produces higher subjective assessment of spatial presence, engagement, emotional arousal and valence, and greater galvanic skin response than for a small visual angle; and that the larger visual angle causes greater acceleration or deceleration in heart rate in response, respectively, to arousing or attention-requiring events than a smaller visual angle. However, physically larger screen size produces higher subjective assessment of emotional arousal, engagement, and presence, but it does not show a significant effect on physiological response. © 2011 IEEE.
