Give an example from everyday life where designers have fit the task to the person. Give an example of where they have not. Explain how this could be addressed. Discuss each in detail.e have all used a vacuum cleaner that is hard to use - old vacuum cleaners were not ergonomically designed. They were bulky, hard to maneuver, and put unnecessary strain on your back and arms. Luckily, companies such as Dyson have pioneered ergonomic vacuum cleaners. We are now spoilt for choice with a myriad of easy to use designs. The Big Ball vacuum cleaner is a joy to use. It has a small power unit that is easy to move along your carpets. Moreover, the vacuum pole itself can be adjusted in height - this means you do not have to bend over when vacuuming. Furthermore, the pole has several different attachments that can make it easier to clean certain areas, such as skirting boards and furniture. One final awesome ergonomic feature is that it self-rights if toppled. Everything about the Big Ball has been carefully engineered with usability in mind
