Course Description
This course provides an intermediate level review of the principles of human factors/ergonomics. The course covers human information processing; man-machine systems; information design; display and control design; static and dynamic anthropometrics; fundamentals of biomechanics; musculoskeletal injuries, including cumulative trauma disorders such as carpal tunnel syndrome; hand tool design; back injuries; vibration; shift work, biological rhythms; and workload assessment. Emphasis is placed on ergonomic methods and techniques to assess the design of modern work environments.

Course Objectives
This course aims to familiarize students with the basic ergonomics information necessary for analyzing and redesigning modern work conditions. Upon completion of this course the student should:

1. Understand the relevance of human information processing and man-machine models for ergonomic design.
2. Acquire critical skills for ergonomic assessment of products and systems.
3. Understand the fundamental requirements to conduct an ergonomic analysis of a work environment.

Course Format
The course meets twice each week for a total of three hours. This time is used for a combination of lecture, practical exercise, software, video, and discussion. Course performance is assessed using project homeworks, a midterm and a final examination.
Class Format: Combination of lecture, practical exercises, software, video, and discussion
Grading Scheme: 50% Examinations (2 non-cumulative exams: Prelim.1 -20%, Final exam - 30%):
50% Homework (three assignments - HW1 - 10%, HW2 - 20%, HW3 - 20% - see table at page bottom)
