Operator interface mounts and arms are articulating components used to hold and position industrial computer monitors, keyboards, or other operator interfaces. Operator interface mounts and arms are designed to improve the physical/spatial relationships between machines and the humans that operate them. This science of these relationships, called ergonomics, is the study of human/machine interactions. Ergonomically-compatible products are designed to maximize productivity and minimize operator fatigue, discomfort, and injury. The goal of using operator interface mounts and arms as part of an ergonomics program is to reduce injuries, illnesses, and musculoskeletal disorders in the workplace.
