Two Experiments on Co-located Mobile Groupware

INTRODUCTION The Dimensional Overlap Model (D.O.) [3] and StimulusResponse Compatibility (SRC) [1,2,4] are two interrelated areas of study from experimental psychology that investigate the relationships between human response performance and the nature of the stimuli that elicits these responses. Decades of research in these areas have shown that the relationship between the stimuli and the required responses greatly affect the speed and accuracy with which users can perform simple tasks.
