Topic 7 - User-centered design
Question 1
HLPaper 1A user-centred approach to design puts the design team in direct contact with the people they are designing for and is also referred to as…
Question 2
HLPaper 1Jeffrey Rubin describes four usability objectives. Which of the following terms best fits the usability objective of designing a product that enables a user to achieve their goals?
Question 3
HLPaper 1What is the name given to products that are accessible and useable by as many people as possible, without the need for adaptation?
Question 4
HLPaper 3The Natural Brush, see Figure 2, is a toothbrush based on sustainable design. The handleis made from 100 % biodegradable bamboo and the bristles are made of Nylon 6 which themanufacturers claim is the most biodegradable nylon in the world.

List two ways in which theNatural Brush is an example of sustainable design.
Outline how theNatural Brush can be seen as an example of ethical consumerism.
Outline one pricing consideration and how it would stimulate sales of theNatural Brush.
Explain how theNautral Brush balances material, health and usability considerations.
Question 5
HLPaper 3HeatSmart has developed a range of thermostats for smart homes that are used to managethe temperature of a room. For example, the temperature of a room can be set to 20 °C atmidday every day.
HeatSmart have recently introduced their Intelligent Thermostat that automatically sets thetemperature of the room based on the preferences of its users. This can lead to a saving ofenergy and is indicated by the green HeatSmart globe icon that appears on the screen.The temperature for the room can be increased by rotating the dial clockwise, see Figure 1.Or it can be decreased by rotating the dial anti-clockwise, see Figure 2.
List two user-centred design (UCD) principles the Intelligent Thermostat’s design teammay have followed.
Outline one way that the Intelligent Thermostat’s design team would have consideredpopulation stereotypes.
Explain how the design of the Intelligent Thermostat’s user interface provides clearfeedback and has a low memory burden for its users.
Question 6
HLPaper 3The first version of the Impossible Burger was released in 2016, with the aim to be“craveable” to meat eaters. To achieve this, Impossible Foods developed a meat substitutethat had everything a “meat lover” looks for in a burger: juicy and flavorful with a pink middleand a convincing texture and smell. This meatless burger even cooks and “bleeds” like beef.
To market the Impossible Burger to meat eaters, Impossible Foods partnered with well-recognizedrestaurants such as Burger King who have included the Impossible Burger ontheir menu. This provided customers the opportunity to try this new food without changingwhere they would normally eat.
List two members that could have been included in the multidisciplinary team thatwould have been used by Impossible Foods to develop the Impossible Burger.
Outline how physio-pleasure was considered in the development of theImpossible Burger.
The development cycle requires considerable consumer testing. Outline whyiterative design is a feature of a pioneering strategy.
Explain why designers would have used personae and secondary personae in theiruser research to develop the Impossible Burger.
Explain how the creators of the Impossible Burger are using product, place and promotion from the marketing mix to make it appeal to meat eaters.
Question 7
HLPaper 1Which of the following research methods in user-centred design (UCD) gathers large quantities of data and groups them based on their natural relationships?
Question 8
HLPaper 1Figure 6 shows a USB cable which can only fit into a computer in one way.
Figure 6: A USB cable
Which characteristic of a good user interface does this demonstrate?
Question 9
HLPaper 1On most modern laptops, when the user switches on the machine, a sound or tune will play. What characteristic of a good user product interface is this an example of?
Question 10
HLPaper 1A common strategy for user-centred design (UCD) involves selecting users to represent the 2.5th and the 97.5th percentile of the population. Products are then tested to ensure that they function efficiently for those users. What does this strategy describe?
