3 Written questions

3 Multiple choice questions

  1. 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.
  2. 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.
  3. 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.

3 True/False questions

  1. Explain the benefits of using digital humans in developing manufacturing
    plants and processes, maintenance and training
    Digital humans enable manufacturing plants to be developed more quickly and manual workflow to be optimized. They improve worker safety and reduce compensation costs resulting from accidents. Machines and other equipment can be positioned to optimize cycle time and avoid hazards, etc. See 8.8


  2. Explain how motion capture is used to digitally represent motionMotion capture can reduce the cost of animation, which otherwise requires the animator to draw either each frame or key frames that are then interpolated. Motion capture saves time and creates more natural movements than manual animation, but is limited to motions that are anatomically possible. Examples are animated super-hero and martial arts.


  3. Identify the advantages of motion capture for digitally representing motionA 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.
