Human factors engineering deals with many areas of concern in daily activities and operations, such as the human-machine interface, the displays to be perceived and the controls to be actuated, so that safer and more effective systems can be designed for humans. This module will focus on the interaction dynamics between the human operator and the machine/system in a human-machine system. It will also include a discussion on the tools and methodologies used in human factors engineering, as well as issues of capabilities and limitations of the human operator.
