Question 1
SLPaper 1Which of the following usually relies on collecting anthropometric data relevant to the 5th percentile only?
Question 2
SLPaper 2With the growth in virtual reality (VR), augmented reality (AR) and mixed reality (MR)* therehas been an increasing interest in virtual interaction design.
Mixed reality interfaces can be accessed by the user through wearing mixed reality glasses. The software maps the physical environment and matches the size of the virtual interface tothe size of the user’s hand.
Figure 6 and Figure 7 show a user interacting with virtual menus linked to physical objectsin the environment.

* mixed reality (MR): overlays and anchors virtual objects to the real world
Question 3
SLPaper 1Designers use an understanding of human factors to...
I. Increase safety
II. Increase ease of use
III. Reduce stress and fatigue
Question 4
HLPaper 1Which of the following is a biomechanical consideration?
Question 5
SLPaper 1Which percentile would be used to calculate the width of a cinema seat?
Question 6
HLPaper 1Which part of the human information processing system would most likely be responsible for a user forgetting how to operate a product?
Question 7
SLPaper 2Zuperzozial is a Dutch company that manufactures a range of kitchenware (plates, cups, servingutensils, and vessels) from biodegradable bioplastic that is made from renewable resources (suchas, corn, sugar cane and grain), see Figure 14.
The environmentally conscious kitchenware is stylish and durable. It also has a similar weight,feel, performance and dimensions to existing ceramic products. Zuperzozial are distributingtheir product through specialist kitchen stores, where they are displayed alongside conventionalkitchenware. Zuperzozial needs to sell the kitchenware at a slightly higher cost than conventionalkitchenware to recover the cost of the new technology used to manufacture using bioplastics.
Outline one psychological factor the Zuperzozial kitchenware’s designers needto consider.
Explain one physical property that the material used in the Zuperzozial kitchenwareneeds to possess.
Explain one advantage of using Finite element analysis (FEA) and one advantage ofusing physical models for testing the Zuperzozial kitchenware.
Explain how Rogers’ characteristics of relative advantage, compatibility andobservability help in the diffusion of the Zuperzozial kitchenware.
Question 8
SLPaper 1Which part of the human information processing system would most likely be affected by mental stress?
Question 9
SLPaper 1In which scale is the order of the values important, but the differences between the values unimportant?
Question 10
SLPaper 2Drones have become more widespread and can be used for leisure, business or militarypurposes. A drone is operated using a handset, see Figure 7.
Figure 7: A drone and its handset
List two reasons why temporary joining techniques are used when a droneis assembled.
Explain why finite element analysis (FEA) would be used in the development ofthe drone.
Explain two ways that drones can become obsolete.
Explain how the study of human factors can be used to improve the comfort, safety and performance of the handset that controls the drone.
