Checks and Balances: A process for evaluating the usability of automated vehicle HMIs

New functions create new challenges! While the quantification of driver distraction can rely on standardized test procedures, there is no commonly agreed upon method for the evaluation of automated vehicle HMIs yet. Therefore, we propose an exemplary test procedure for empirical usability testing as well as heuristic usability evaluation for SAE Level 3 systems.


This talk is for everyone interested in standardized usability testing in the automotive industry. It will outline the role of NHTSA’s automated vehicle policy minimal HMI recommendations and our approach to evaluating those with an objective, reliable and valid procedure.
