Course Goals § Upon completion of ISE 412, students will be able to: l l l ISE 412 - 1 Develop, conduct, and evaluate the results of human factors research. Develop models of human-machine systems. Develop information requirements based on understanding of human sensory processing and cognition. Develop action requirements based on understanding of human response capabilities and limitations. Design human-machine interactive systems based on appropriate models, information and action requirements, and an understanding of human abilities, limitations, and preferences. 2

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. ) § Understand how the concepts you learn in ISE 412 integrate with what you’ve learned, are learning, or will learn in other courses and as you progress in your career.
