Lewis Barbe a board-certified engineer who just received Emeritus status with the Human Factors and Ergonomics Society for his commitment to public safety. The HFES promotes the discovery and exchange of knowledge that pertains to human beings, and the design of the systems and devices that they interact with.
As Lewis Barbe knows, improper interaction can lead to physical strain and injury. "Like your computer," he said, by way of illustration. "Your hand and elbow have to be the same level as a computer keyboard."
Whether you are using a desktop computer or a laptop, there are many considerations that come to bear in terms of the body's relationship to the computer. As Lewis Barbe knows, it is important to use a good chair with proper back support and to keep both feet on the floor. The top of the monitor, he says, should be two to three inches about eye level, and there should be no glare on the screen. Users are advised to sit at arms' length from the monitor.
The height of the desk the computer is on is also an important consideration. The desktop should be adjusted in relationship to the height of the chair, so that the elbows of the user are bent at ninety-degree angles, the forearms are parallel to the floor, the wrist is held straight, and the shoulders are relaxed.
Opinions vary on document holders. Lewis Barbe says he thinks it is a good idea to use a document holder that is in line with the computer screen.
