ABSTRACT

In this paper we propose new metrics to investigate computer-based multitasking behavior. These metrics range from a very lean dichotomous variable to a very rich measure based on switches that combines user, task and technology considerations. We demonstrate how to calculate these measures with an exploratory study based on self-reported user logs. The development of new metrics to research multitasking behavior lays the foundation to incorporate this variable in future studies of human-computer interaction.
