Ergonomics is a scientific discipline that centers on the design and arrangement of objects and environments to optimize efficiency and safety in human interactions. This field of study, as defined by Merriam-Webster, is concerned with the fit between individuals and their work. The name ergonomics is derived from the Greek words ergon, which means work, and nomos, which signifies law. The primary aim of ergonomics is to prevent musculoskeletal disorders and soft tissue injuries caused by exposure to factors such as force, vibration, repetitive motion, and awkward posture. By enhancing product design and workspace arrangement, ergonomics seeks to minimize strain, fatigue, and injuries.

The ultimate goal of ergonomics is to promote a comfortable and relaxed posture that enhances worker efficiency and productivity. The Ergonomics and Appropriate Technologies Practical Manual sets out to achieve the following objectives: (a) to raise awareness of the relevance of ergonomics in daily life and its practical applications, (b) to gain knowledge about the work, worker, and workplace, and (c) to understand the various factors that influence worker performance at the workplace.
