The future of automotive vehicle interiors is becoming more complex each year. Extensive consumer research demonstrates that consumers want new convenience features. However, increased electronics and communications content could potentially pose unwanted distractions to the driver. This study examined objective variations in driver performance while tasked with operating a variety of interior feature controls. Data from thirty-one test participants were used in the evaluation of three control interface alternatives. Objective driving simulator measurements included vehicle velocity, steering wheel angle, and vehicle position within the driving lane. Session video and subjective responses were also recorded. Examples of data analysis and interesting findings will be discussed.
