Title

Effects of Multitasking on Human Performance

Abstract

Multitasking is an integral part of human behavior. As technology advances, multitasking is commonly observed as users interact with systems. This paper summarizes the existing literature on this topic and examines the relationship between task characteristics and multi-tasking performance. Specifically, we are interested in examining whether mental workload increases as task difficulty in multitasking increases, whether there is any performance decrease in multitasking as mental workload increases, and whether users perform better in between-channel multitasking than within-channel multitasking. To address these research questions, we conducted a lab experiment using eye-tracking equipment. Twenty users were asked to perform two tasks simultaneously, with varying difficulty levels. One task was performed on eye-tracker controlled software and the other was using a reaction timer. User's eye movements, as well as time and accuracy for respond to both tasks were captured and analyzed. Both visual and auditory tasks were considered. The results supported our hypotheses.
