The person in the workplace on the left would be A and the person on the workplace on the right is B
-A is messy as there is a lot of unnecessary stuff on the table with little workspace and is cluttered, making it hard for more things to be placed and it is easy for things like mugs and cups to topple, and his chair is also breaking apart, so he puts the broken parts on the table. B has much less items on his table so he has space for him to feel comfortable.
-A's computer monitor screen is too far from him, so he has to use glasses and a magnifying glass to help him to see what is on his screen, making it hard and wastes a lot of time to do that. However B's monitor screen is adjustable, allowing him to adjust the screen to suit the distance from the screen to himself, saving the time that would be used to looking at the screen through the glasses and magnifying glass. The table also has a access rail which allows the user to place items such as monitor and free up space on the table.
-A has two desktop lamps on his table to use when it is darker, however, when he needs to adjust his lamps, he would get burnt by his lamps as it overheated, making it dangerous to the user, if he were to experiment the brightness of the lamps, it would be wasting time. The lamp is also too bright and in the wrong position. The light of both lamps is also too glaring, making A wear a pair of goggles, and the glare of the light also made it harder for A to see the computer monitor. B's lamp light is smaller, but it can be adjusted without getting burnt, and since it covers a smaller area, the lamp allows him to focus on what he is doing currently, the light would not spread around the workplace, and also not having a glare that would hurt his eyes. Since the lamp is adjustable, he can move it away when he does not need it so the lamp does not obstruct what he is doing afterwards.
-A's chair is too high, taking away his freedom of movement of his hands, and also is complicated and has parts that will fall out, making it inconvenient for A to take his mug to drink or any other objects. Since the chair decreases A's range of which his arm can reach up to, he has to move his chair around, wasting some time. B's chair has a adjustable armrest, allowing him to move it upwards for his arms to rest on when he leans backwards and holds his cup to drink. This allows him to adjust to different situations. B's chair also has a back rest and neck rest, to give comfort to the user. The chair is also flexible, allowing the user to adjust according to the sitting position of the user, giving the user a freedom of movement.
-In A's workspace, the laptop is not high enough, making the user keep on changing the position of books or files, giving him an awkward position to type. In B's workspace, B has a laptop holder which allows B to raise the screen up to a comfortable position and also adjust the height of the laptop's screen.
2) A has a messy area, making work more troublesome and uncomfortable to do. And on B's desk, it is more empty to allow B to work comfortably so he would not feel restrained.
3) When designing a workspace, we have to consider the comfort the user would feel when using the workspace, the space the user has, the simplicity, efficiency, freedom of movement, the lighting and the safety.
4) Ergonomics allow workspaces or work environment to be more comfortable and also allows the user to work more efficiently and have more space to have freedom of movement.
