Ergonomics consideration in design focuses on the relationship between humans and machines. Key factors include the design of controls to match human anatomy and posture, the working environment including lighting, noise, temperature and humidity levels, and the energy expenditure required for hand and foot operations. Aesthetic considerations aim to make products appealing through their shape, color, symmetry, balance, materials, surface finish, impression, purpose, variety, continuity and style.
