3 Multiple choice questions
- There can be more design iterations in less time. This results in higher product quality, which meets human requirements more accurately. Digital prototypes are cheaper to produce than physical prototypes. Products are safer as a result of more thorough analysis of safety aspects.
- Before a physical prototype- Digital humans allows the design to be optimized for user comfort, visibility and access to controls, that the user population will be able to climb in and out of the vehicle easily and controls and foot pedals are within the reach, that the vehicle can be maintained and the strength required to operate it is within the normal range.
- A person wears sensors- either a set of acoustic, inertial, LED, magnetic or reflective marker at each joint. Sensors track the position of the markers as the person moves to develop a digital representation of the motion.
3 True/False questions
Explain how motion capture contributes to the development of a digital human → A motion capture session records the movements of the actor, not his or her visual appearance. The captured movements are mapped to a 3D model (human, giant robot) created by a computer artist, to move the model in the same way.
Discuss how digital humans can enhance human factors research → Digital humans can be used to represent joint resistance, discomfort, reach envelopes and visual fields. They can be used, for example, to measure the impact of clothing on human performance.
Explain the benefits of using digital humans in developing manufacturing
plants and processes, maintenance and training → Digital humans can be used in e-commerce to model clothing products. A customer can produce a model corresponding to his or her body shape, size and look. The model can then try on clothing so that the customer can see what it might look like.
