Ergonomics

Using a digital camera, take 4 pictures of a subject that can be either yourself or someone else in the postures shown on page 52 of your textbook. Measure the body dimensions of those listed in table 1.5, page 48 of your textbook. You need to measure only items 1 to 27 (also shown in pages 52 and 53) - {Please see attached pictures of the textbook pages mentioned above as well as related videos and materials relevant to the assignment in the file section of this order} Please attach the pictures to the report. The pictures will remain confidential, but good practice is to cover the eyes using a smiley face or grey block.

  1. Watch the following video: Ruler method video (provided on the file section). Measure your body height using a measuring tape and then use the ruler method to measure your height. Which method is easier? Ruler method or measuring tape? Explain.
  2. What are the main errors with this methodology? (hint-the whole procedure)
  3. What are the main errors with using the camera?
  4. How can you improve this method to reduce error?
  5. What are the advantage and disadvantage of this method?
  6. What are the other common methods of anthropometry? (3 names, 3 examples-search via internet if you like).
  7. The anthropometric table attached in the file section is an excel sheet file. This anthropometric table is an accumulation of the results from this same exercise completed by the students this course over the last several years. This table will be used to compare the findings for your subject and to complete the activities as outlined below. First, watch this video “ Excel Intro” in the file section of this order to see how the excel sheet works.

8- Measure the body size of the 4 images you took above using the ruler method for the variables given in the excel sheet (you are the last person in the sheet, fill the cells under each column).

9- Determine the average and standard deviation of each body segment after adding your results.

10- Determine the percentile of your subject for the class population. List the percentile of 5 body dimensions and explain what they mean. Watch the “Excel Percentile video” in the attached file section of this order.

11- How representative do you think this sample group is? (i.e errors, bias etc).

12- Determine the coefficient correlation of your body segments (give 5 examples). Watch the following video: “Excel Correlation” in the file section. Please ignore when I refer you to an article that you should read. Just follow the following steps].

13- From the module readings and using correlation coefficient in the above video; discuss why one body dimension cannot be directly correlated to another body dimension. Give an example of this practice in the clothing industry.

14- What you are expected to complete for this assignment order?

  1. A complete report including cover page. An intro about Anthropometry. The objective of this experiment, methodology, results: Four or more Pictures showing YOU or your participant in the defined postures or holding the scale in the background. Make sure the scale is kept straight and the location of the camera is consistent (use a camera or a stand if possible).
  2. Answer to the questions# 2-6.
  3. Find mean and SD of the body dimensions of the class (including the anthropometric size you added to the excel sheet). Make a table including the average and SD of all the body sizes including your body si
