Practice typing and computer posture whether standing or sitting to type, can assist you in answering the following questions:
The following tips can be of great help to you in answering the above questions.
The height of the chair should be adjusted so that your feet are flat on the floor and your thighs are parallel to the floor. If your feet are too short and cannot reach the ground, place a box or some item under your feet to prevent from hanging in the air.
Keep your feet slightly apart, braced firmly on the floor.
Never cross your legs or wind them around the chair. Remember the aim is to achieve a comfortable position which will avoid fatigue.
Your body should be relaxed, with the backrest of the chair adjusted so that it supports your back and not your shoulders.
Set the backrest so that you are leaning slightly forward. Never try to type leaning backwards.
Sit so that you are one hand-span from the front edge of the computer, which should be parallel to the edge of your desk.
It is very important that you are the right distance from the machine. Check this point every time you sit down to type.
Your arms and elbows should hang loosely.
Make sure that your finger-nails are not so long that they get in the way of the keys.
Your fingers should be in a curved postion so that only the tips touch the keys, while your hands should be at an angle of roughly forty five degrees to the computer.
The palm of your hands must be clear off the computer and the space bar in particular.
Your arms should hang naturally at your sides with the elbows well in.
Your wrist should be straight not humped and your fingers curved. Strike each key lightly but firmly and evenly with the finger tip.
Make sure that only one key is struck at a time and allowed to return to its place before the next key is struck. This will avoid making mistakes.
