IB Design Technology Topic C1.2: Inclusive Design Questionbank

(c) Compare the strategies used in Figure 1 and Figure 2 to support users with different impairments.

(e) Discuss how designing for extremes has been applied across all three figures in this kiosk system.

An electric toothbrush with larger grips and single-button use reflects:

Read the following stimulus and answer parts (a) and (b).

Voice control, shown here in a smart speaker, was developed partly so that users with a visual or a motor impairment could operate devices without needing to see a screen or use their hands.

(a) Voice control is now used by huge numbers of people who have no impairment. Which advantage of designing for extreme users does this best illustrate?

(b) The textbook lists other advantages of designing for extremes. Which of the following is one of them?

Which element of this museum exhibit reflects inclusive design principles?

Designing mainstream products to be usable by the widest possible range of people, regardless of age or ability, without needing special adaptation

Designing a separate, specialised version of a product only for people with disabilities

Designing every product to fit the single average user

Designing products only for the strongest and most able users

(a) The screen features bright, clearly labelled icons with a black background.

(Fig 1)

Outline two reasons why Figure 1’s design improves accessibility for elderly users.

(b) Physical control panel with a rotary dial, Braille labels, and audio jack for headphones

Identify one feature in Figure 2 that supports users with visual impairments.

(d) Users can press a button to lower and tilt the screen to their preferred height.

Explain how Figure 3 demonstrates inclusive design principles.

Minimal user testing

Hybrid manufacturing

Redundant design

Design for extremes

Designing for extreme users always makes a product cheaper to manufacture

Designing for extreme users stops the product working for able-bodied users

Designing for extreme users only ever helps that small group and no one else

A solution created for extreme users benefits a much wider audience, here everyone who needs hands-free operation

It removes the need to test the product with any users

It future-proofs designs, since addressing extreme cases now prepares products for changing future needs, such as an ageing population

It always reduces the number of features a product can have

It makes the product usable only in one fixed environment
