In this paper we evaluate the safety of the driver whenusing an embedded communication device while driving.As a part of our research, four different tasks were preformedwith the device in order to evaluate the efficiencyand safety of the drivers under three different conditions:one visual and two different auditory conditions. In the visualcondition, various menu items were shown on a smallLCD screen attached to the dashboard. In the auditory conditions,the same menu items were presented with spatialsounds distributed on a virtual ring around the user’s head.The same custom-made interaction device attached to thesteering wheel was used in all three conditions, enablingsimple and safe interaction with the device while driving. The auditory interface proved to be as fast as the visual one, while at the same time enabling a significantly safer driving and higher satisfaction of the users. The measured workload also appeared to be lower when using the auditory interfaces.
