Choosing to interleave: Human error and information access cost

in CHI '12: Proceedings of the SIGCHI Conference on Human Factors in Computing Systems, Journal article

Abstract

People are prone to making more errors when multitasking. Thus in safety-critical
environments, it is often considered safer to perform tasks sequentially. Here we explore
how the cost of accessing information affects the way people choose to interleave. An
empirical study based on a medical scenario was conducted. Participants had to program
infusion pump devices using information from a prescription form. The physical and mental
effort involved in accessing information was manipulated. This was achieved by varying ...
