As we saw in the section on fear of computers, technology can have a profound effect on people. Fear, however, is not the only element that should be considered. People can also be affected by:
The physical demands placed on them by the technology.
The way that personal computers can impact job performance.
As more people spend increasing amounts of their day in front of video display terminals (VDT), more concern is being expressed for their physical well-being. This has increased interest in ergonomics, the study of the relationship between the human body and the machines we use.
One reason for the heightened interest is the growing concern over issues of health, comfort, and stress associated with the growing use of personal computers. Studies by several groups have concluded that there are a number of comfort issues related to the use of personal computers and computer terminals. Among the most cited problems is poor lighting and inadequate furniture that was often designed before anyone ever heard of office automation. According to a 1984 study released by the Administrative. Management Society Foundation, the most commonly reported problems associated with VDTs include pain in the shoulders, neck, buck, arms, and hands. Visual problems include burning eyes, headaches, focusing problems, and stress. These are brought about in part by poor lighting, problems of brightness contrast I twin characters and background, and flickering. Stress is also a factor that needs to be considered. Research landings indicate that some users show anxiety, depression, irritability, anger, confusion, and fatigue when working with terminals Jobs content can also play a factor. According to the Administrative Management Society study, clerical users complain more about discomfort than professional users. This seems to be a result of how personal computers fit into various jobs. For professional workers, they are often problem-solving tools, while data entry left to the clerks. In short, professional workers often use computers to perform tasks that result in something they can take pride in. Clerks, on the other hand, end up doing the simple repetitive jobs in which the end results are not as visible or meaningful. These are all issue that need to be conveyed to managers and owners, Training program can certainly help make the various levels of an organization aware  of the complexities of office automation tools, such as the personal computer, an can help educate people on the human needs in working with such a technology.
