21. Introduction - Lecture 1 Q. Ergonomics and human factors are the same. T/F. Briefly explain the similarities and differences between ergonomics and human factors for work design. Q. After a human factors analysis, possible areas of improvement include…

22. Lab 1 Lifelong learning L. How would you evaluate the work described in the paper titled …. L. What information can be gained from reading the abstract of that paper (shown) in relation to the “List of 10 ways…”. Justify your answer through brief ‘quotes’ from the abstract. L. What is not shown in the abstract?

23. Lab 1 -Other possible questions on supplementary readings Consider the paper by ….on driving simulator (title and authors given). Weaknesses were highlighted in the presentation related to… * Briefly explain the method that was used, and what are the implications of this weakness?* Why is the paper included in the literature considering its weakness (what is its strength/or contribution?)* *These questions may be beyond the level of our discussion in class – hence, they may not be appropriate for the exam 1. However, those questions that were asked and discussed in lab today may still be considered within the scope of exam 1 content.
