Ergonomics I

1) Workplace 1 is more cluttered and messy than workplace 2 which is nice, neat and spacious. Workplace 1 has a lot of unnecessary things on its table.
-For comfort and simplicity, workplace 1 is way too complicated in the case of the chairs that they are using and workplace 2 is much better. The person in workplace one is having trouble adjusting the height and position of the chair, whether the height is too low or high and the position too close or too far away from the desk,thus this also makes the chair uncomfortable. Workplace 2 however, uses the liberty chair which is easy to adjust to a comfortable height and position. It also has armrests and allows the user to lean back to increase comfort even more. The 2nd workplace also uses an access rail to allow the user to place items such as monitor and hence free up space on the table.
-For incorrect height and depth, workplace 1's user is having trouble to look at the screen and has to squint and use a magnifying glass to look at the screen of the monitor which means that the height and depth of the monitor is not correct.He uses a laptop but he needs to stack laptop on top of books. Workplace 2 however, utilises the M7 monitor arm to adjust the monitor to a suitable height and depth of the monitor for better viewing pleasure, and when the monitor is not needed, the arm allows it to go back and take up minimum space on the desk.The laptop holder allows the user to raise up the screen of the laptop to a comfortable price.
-For task lighting, workplace 1's user is having difficulty adjusting the lighting for him to do his work. The first lamp has a pretty bad design as it must be adjusting by moving the lamp which is hot because of the heat it produces when light is used. It will overheat which is dangerous for user, the user is thus unable to adjust the lights. It is way too bright, wrong position and glare from screen. While the other lights he uses is way too bright for him to see and seems like it cannot be adjusted. Workplace 2 however, utilises a different light, the lamp he utilises has a handle which is not hot so that he can adjust the light without worrying about burning his hand, it is not glaring.
-For freedom of movement, workplace 1's user does not have sufficient desk space as it is cluttered with papers and there are no special compartments for keyboard. The chair is yet again another problem, the armrest is way too high and not rigid enough causing the man's arm to drop. Workplace 2 however, uses the freedom chair which has adjustable armrests that are rigid and when not in use, does not take up much space on the chair, the chair also allows to user to lean back, this allows freedom of movement. There is also a neck rest to give support to the user.

2) The second workplace is preferred as it features good designs necessary for a neat, tidy and comfortable workplace. Some of these features include the freedom chair which has adjustable armrests that allows maximum comfort for the user. Another example would include M7 monitor arm that can adjust the height and depth of the monitor so that it is not a pain for the eyes.

3)The considerations should include freedom of movement, task lighting, height and depth and comfort and simplicity. These are needed for maximum convenience and productivity in the workplace.

4)It is important as man does work for most of his time so the way and method of doing the work can increase his efficiency. This could mean the difference of finishing work in time or not in time. If efficiency is increased, more work can be done and if this keeps up, it could also affect our economy and more, for the better.

For ergonomics, we look at :
-Comfort:includes simplicity, space, efficiency, freedom of movement, lighting, physiological.
