Ergonomics

Ergonomics concerns the relationship of person to machine. The prevalence of computing in the work environment has put anyone who uses a computer for more than two to four hours a day at risk for repetitive strain injury (RSI).(14) RSI is an umbrella term for cumulative trauma disorders produced by prolonged, repetitive, forceful, or awkward movements, particularly of the arm and hand.(14) Carpal tunnel syndrome, tendonitis, and other ailments of the fingers, arms, shoulders, and back are examples of RSI, and they can severely limit computer access. RSI is easy to prevent if people are educated about the correct use and positioning of keyboard and mouse. Yet cases of RSI are increasing and it is estimated that disabilities caused by it will limit computer access for many people.

SCSU senior Scott MacDonald uses the university's Center for Adaptive Technology; the height of the workstations accommodates his wheelchair. To accommodate those with carpal tunnel syndrome or various arthritic conditions, there are several adjustable keyboards, including the Goldtouch Adjustable Keyboard, which allows the user to adjust the keyboard to a more comfortable position. In addition, there are adjustable-height worktables that can accommodate wheelchairs, (see image at right) and there are a variety of chairs that have adjustable arms and backs for users who need extra support or have back problems.
