Feeling a bit stiff or painful at the end of the day? Poor ergonomics can be the problem. Think about the way you work. Humans are not designed to sit at their desks and work all day. This is why it is important to ensure that we practice good human-computer interaction. Fortunately, some simple adjustments can solve these workplace problems without spending a lot of money.
A comfortable table and chair with a support back is very important to prevent a strain on the waist. You should adjust the height of the chair so that your feet are flat on the floor while your knees are bent about 90 degrees. You should be able to sit in a chair and let the top of the table meet your elbows.
Your computer monitor should meet you in sight, so you don't have to tighten your neck. Many newer flat panel displays have brackets that can be adjusted in height and angle. If the screen still looks too far to read correctly, try changing the resolution to prevent eye strain.
Finally, the most important are the keyboard and mouse. Many people suffer from tendinitis and carpal tunnel syndrome, and these devices are not used properly. Again, 90 degrees is a magic number, your arms should be bent so much at the elbows that your forearms can be placed comfortably on the table. If possible, you should also adjust the angle of the keyboard and mouse so that you don't have to bend your wrist to operate the device. While standard desktop keyboards usually have very small feet and can lift the top slightly, you can purchase a keyboard that is designed to be out of the box. These keyboards usually have a space in the middle so your hands can type comfortably without getting so close.
In today's graphical computing environment, a good ergonomic mouse or trackball is as important as an ergonomic keyboard, if not more important. At the very least, you should buy a mouse pad with a raised wrist pad. Although they may take some time to adapt, trackballs are even better for your health because they eliminate many of the slips associated with using the mouse.
By practicing computer security by following these simple computational ergonomic steps, you can prevent many workplace problems.
