ISE 412: Human Factors Engineering

Dr. Laura Moody

Fall, 2005

Course Goals

Upon completion of ISE 412, students will be able to: 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.

ISE 412 - 1 3

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 412 - 1 4

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.

Take out a full sheet of paper. Put your name in the upper right corner. Draw a vertical line down the center of the page. At the top, label the left side “Notes” and the right side

“Questions/Comments”. 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.

Understanding the Human Factors Problem

What information is needed? What is available?

How is information obtained / presented?

How does the person understand the situation? How does he/she know what to do?

What actions are available? How are they initiated?

What is the result of the person’s action?

Understanding HF in Consumer Products

Hierarchy of User Needs (from Bonapace, 2002)

Examples …

safety and well-being

pleasure

usability

functionality

ISE 412 - 1 12

‘Foundational’ Human Factors: 1st Three Levels

“Usability” : the extent to which a product can be used by specified users to achieve

specified goals with effectiveness, efficiency, and satisfaction in a specified

context of use.(ISO 9241-11)

For Example:

ISE 412 - 1 13

Towards the ‘New’ Human Factors in Product Design: Adding ‘Desirable’

“Break out of the ‘sea of white’”

Provide a ‘useful’ and ‘usable’ product.

Meet / exceed consumer needs.

For Example:

safety and well-being

pleasure

usability

functionality

Now, back to the listening exercise …

Use only your own notes from the first part of the exercise.

In the first 3 minutes, answer as many of the first 14 questions as you can.

You may also move on to the last 3 if you have finished as many of the first 14 as you can before time is called.

When I call time, you will have time to address the last 3 questions.

When you are finished, hand in your notes and the question sheet. You are done for the day!
