Choose an item from the following list or one of your own. Your selection should be based on the ease with which your group will be able to access, measure, and evaluate the item

Part B – Conducting a design evaluation

In this part of the lab assignment you will evaluate a particular device with respect to the task(s) being performed and the physical characteristics of the people performing the task(s).

1). Choose an item from the following list or one of your own. Your selection should be based on the ease with which your group will be able to access, measure, and evaluate the item. Examples of items to investigate include:

A). Supermarket shelf height/Library book shelve height B). handles on a shopping cart, height, diameter, width C). Depth, width, length of the shopping cart

D). Toilet height, location of flusher, toilet paper, etc. E). Kitchen sinks height, reach to taps, etc.

• Diameter and length of the handle on a golf club G). Rail height and gaps on a balcony or stairwell H). something of your own choosing
  • Take a photo or create a detailed (to scale) sketch of someone using the item (e.g. one of your group).

Requirements Part B:

• Describe the item you are evaluating, as well as the specific tasks you expect a person to be able to perform (e.g., reaching items on the supermarket shelves/Library shelves, retrieving items from the shopping cart at checkout, ) and why the body dimensions you investigated are relevant.
• Determine and measure what body measures are important when people use/interact with this item (e.g. forward reach, sitting eye height, stature, body reach ). Note: you do not necessarily have to take into account all tasks that might be required – e.g., you can discuss reaching items on a shelf but not cleaning the shelf or stocking. Just be clear which tasks you are supporting and define relevant body dimensions accordingly.
• Measure these dimensions on the actual item as
• Compile and compare the relevant body dimensions and then measured item dimensions from the item you chose to evaluate in a
• Use one of the anthropometric data sources available to you to find the relevant body dimensions for the population of

Comment on these dimensions (do the item dimensions present a potential problem for the user, did you note any difficulties in use that can be explained by the differences between the user dimensions and the item dimensions, etc.?)

• Identify specific concerns you noted with respect to the device you evaluated (e.g., depth of the shopping cart) and make (e.g., “cart should be no more than xx inches deep in order for the 5th percentile female to be able to reach all items in the cart.”).Use one of the anthropometric data sources available to you to find the relevant body dimensions for the population of interest.

• How can the calculated percentiles help the design process?

Conclusions:

• Discuss any insights you have gained from the data on your individual data and, if applicable, the data from others in the
• Discuss the real usefulness of this data from an engineering design viewpoint. How might an engineer or designer use the information? What would be required in order for this to be really useful? 9). Do you prefer standing or sitting at work? Explain your answer?
