Ergonomics is the applied science focused on designing interactions between people and objects to maximize safety, comfort, and efficiency. It blends understanding of human anatomy and movement with how tools, equipment, and workspaces are arranged, so tasks are performed with minimal strain and error. In practice, this means designing chair height, table layout, instrument handles, and control placements to fit how the body naturally moves and works. The other terms describe related areas: kinesiology studies how the body moves; biomechanics analyzes the forces and mechanics of movement; physiology examines how body systems function. Ergonomics specifically targets the human–object interaction to improve safety and performance.
