Ergonomics aims to design workplaces and tools to maximize human efficiency and comfort while minimizing health risks. It takes into account human abilities and limitations to ensure tools and work environments are properly suited for human physiology and psychology. Examples of ergonomic improvements include adjustable keyboards and chairs, clearly marked vehicle controls, and workplace designs that avoid prolonged static postures that can cause injury over time. Proper ergonomics in design is important for occupational safety and preventing repetitive strain injuries.
