Study of Ergonomics determine the interaction between humans and other elements of a system, which is related to a work place. When it is applied to the computer it is concerned with the things like: The type of chair on which user sited, posture sitting at the chair, height of the desk, distance from user’s eye to computer also involve number of other factors. It is a design of computer system which are easier to use and put less strain on your body. Further we look two types of devices keyboards and mice.
These keyboards are designed in v shape because in natural when you brings your hands together they are placed at an angle. This makes it to type at a slightly different angle which is more natural. Which reduces strain and many more related problems. Some keyboard design split the keyboard into two halves and half for each hand so under that half side all the keys come should operate by one hand. Designers exclaimed that ergonomic keyboard reduce injury to some extent but they are limited evidence to back up these claims most of the time it depends on individual preferences. These keyboards are expensive then the regular ones, but also give a little more comfort.
Ergonomic mouse are used to prevent injuries such as Carpal Tunnel Syndrome. As the price is high but who can put a price on health? The reason why users experience discomfort and pain in wrist and hands because ordinary mouse is not the best fit. An ergonomic mouse prevent undue stress on your forearm because while doing work you are not noticing on your wrist that how much sort of twist when you using it. So it comes in multiple size according to hand side also and for left hand users. An ergonomic natural adapts your position. An ordinary mouse is also too slippery. This cause to tense our fingers to keep around mouse while using it. Just take an example how much more effort you take to walk a slippery floor have you notice how much your body get tensed this is similar with the hands while using ordinary mouse.
