Tutorial 2 Ergonomics is a science in itself that focuses on the relationship between human and device. Its goal is to fully optimize a person’s usage of that device so they can get the most efficient results. Ergonomics attempt to make the lives of the user as easy as possible. **(HFESA)** Ergonomics can be divided into three different realms. // Physical Ergonomics // : deals with the anatomical, anthropometric, physiological and biochemical relationships between the product and its user. Creators of these products often focus on unnoticeable aspects of their invention such as working postures, materials handling, repetitive movements, work-related musculoskeletal disorders, workplace layout, safety and health. **(HFESA)** // Cognitive Ergonomics // : deals with mental usability of the product. If people have difficulty understanding the product, they are not likely to continue keep on using it. This interaction is very important because companies want their customers to have an uncomplicated interactive experience. **(HFESA)** // Organizational Ergonomics: // focuses on improving sociotechnical systems, including their organisational structures, policies, and processes. **(HFESA)**  Additional Advice: 1) Rather than just adding signage to warn on coming cars of pedestrians walking to and from the parking lot, a fully functioning crosswalk should be built. Proper traffic light should be put into place as to the fact they are extremely visible and much safer than that of a simple stop sign. This will help prevent accidents by reducing the likelihood of jay walking. 2) http://www.ehs.utoronto.ca/services/Ergonomics/products/kbtray.htm
 * List the three definitions of 'ergonomics'.**
 * Choose one of the case studies, and add an additional recommendation to one of them in step two as 'advice'.**
 * Issue ** : A shopping centre was reviewing the safe access for customers from the car park and within the centre itself, being concerned after a few ‘near-miss’ incidents relating to pedestrian safety and slips, trips and falls within the complex.
 * Find an example of a product which is ergonomically sound, and add a link to an article about this product.**
