Project: in-vehicle Auditory Interface

We looked at how an in-Vehicle Auditory User Interface can improve the safety of drivers. Therefore we built a very simple graphical interface and compared it to a spatial auditory interface. They both had the same functionality: the user could navigate a hierarchical mobile phone menu (we used a stripped down menu from the Nokia S60 Series) and access typical items like contacts, music player, text messaging, etc. The visual interface was built to be displayed on on-board screens like being used in navigation systems while the auditory interface was spatially spread out using a 7.1 speaker system (resembling the on-board speaker system).
