Aaron’s specialty is human-robot interaction and advanced transportation. He is interested in how to enable timely and appropriate interaction when interfaces are restricted through design, tasks, the environment, time pressures, and/or user abilities. He utilizes training and experience in robotics, intelligent transportation, rehabilitation, human factors and ergonomics, human-computer interaction, universal design, and research methods.
