Example 4
hardExplain the concept of 'universal design' and how it differs from 'designing for disability'. Give an example of a technology feature that was created for accessibility but is now used by everyone.
Solution
- 1 Step 1: Universal design creates products usable by the widest range of people from the outset, without needing adaptation. It is proactive. 'Designing for disability' adds accessibility features after the main design, which is reactive and often less effective.
- 2 Step 2: Example: text-to-speech was developed for blind users but is now widely used for audiobooks, GPS navigation, virtual assistants (Siri, Alexa), and hands-free operation while driving.
- 3 Step 3: Other examples: automatic doors (originally for wheelchair users), voice control, predictive text (originally for users with motor difficulties). The 'curb cut effect' — features designed for accessibility benefit everyone.
Answer
Universal design is proactive inclusion for all users. Text-to-speech, created for blind users, is now used by everyone (audiobooks, GPS, virtual assistants). Accessibility features often benefit all users.
The curb cut effect shows that designing for the margins benefits the mainstream. Investing in accessibility is not just ethical — it creates better products for everyone.
About Accessibility
