Final answer:
Ergonomics, or human factors psychology, is the study of designing objects and systems to fit human needs. The ideal physical setup for using computing devices includes proper monitor placement, keyboard and mouse positioning, an adjustable chair with lumbar support, and a desk at the correct height.
Step-by-step explanation:
Ergonomics, also known as human factors psychology, is the study of designing and arranging objects and systems to fit the needs of humans. When it comes to the ideal physical setup for using computing devices, there are several factors to consider. First, the placement of the monitor should be at eye level to avoid neck strain. The keyboard and mouse should be positioned so that the wrists are straight and relaxed. Additionally, an adjustable chair with proper lumbar support and a desk at the right height are important for maintaining good posture while using computing devices.
