Computer simulation of a variety of mechanical and biological aspects of the human body.

• A. Digital human
• B. Fidelity
• C. Formal drawing techniques
• D. Animation

Answer: (A)

A digital human is a computer-generated representation that can model and simulate how both mechanical and biological aspects of the body work. This kind of model lets researchers and designers test movement, forces, tissue behavior, and physiological processes within a single integrated virtual body, enabling safe, repeatable investigations and visualizations. Fidelity refers to how accurately a simulation matches real life, which is about the quality of the model rather than its name. Formal drawing techniques describe static representations, not interactive simulations of body systems. Animation deals with showing motion, which is a feature that can accompany a digital human but does not name the model itself.
