ISE 412: Human Factors Engineering Dr. Laura Moody Fall, 2005

Course Goals §Upon completion of ISE 412, students will be able to: l Develop, conduct, and evaluate the results of human factors research. l Develop models of human-machine systems. l Develop information requirements based on understanding of human sensory processing and cognition. l Develop action requirements based on understanding of human response capabilities and limitations. l Design human-machine interactive systems based on appropriate models, information and action requirements, and an understanding of human abilities, limitations, and preferences.

ISE In addition, you should be able to … §Listen purposefully. §Observe actively. §Ask questions to gain a deeper understanding. §Use observation and questioning to better understand how people relate to technology and their environment (and vice versa.)

ISE Before we go any further … §Imagine that you are an engineer looking for opportunities to develop projects or products to improve life in a small town. l Take out a full sheet of paper. l Put your name in the upper right corner. l Draw a vertical line down the center of the page. l At the top, label the left side “Notes” and the right side “Questions/Comments”. l Listen to the 5-minute audio presentation. Take careful notes. Write down questions or comments as they occur to you. Use the back of the page and additional sheets as needed.
