The purpose of this article was to describe the possibilities gained by using an electronic voting system (EVS), the existing evidence to determine whether an EVS affects learning proceeds, challenges in EVS and perspectives for EVS in Danish medical training. Audience Response-Systems (ARS) seem suited to enhance participants' activity and attention. The technology as such holds the potential to enhance learning outcome, but changes in the pedagogical method are needed. More studies examining the use of new wireless, mobile voting systems are required.
