Ergonomics is the study of how humans interact with all kinds of machines, not just computers. But today, with so many using a computer as an everyday part of their jobs, there is considerable focus on the ergonomic issues that are related to the use of the computer. As health concerns arise, the computer industry and others are attempting to solve the problems related to continual use of computers. Special attention has been focused on ergonomic factors that can improve the design of input and output devices in order to reduce fatigue and other work-related problems. Knowing that there are potential problems associated with computer use, businesses and other organizations are now paying more attention to the work environment, making sure that desks and chairs are adjustable and that there are appropriate light levels. Many companies are now purchasing special devices that are designed to improve the working conditions for their employees who use computers.
