Also note that invariably when we design something that can be used by those with disabilities, we often make it better for everyone.

The quote by Donald Norman emphasizes the principle of inclusive design, which suggests that creating products or systems accessible to people with disabilities ultimately benefits all users. When he says, “when we design something that can be used by those with disabilities, we often make it better for everyone,” he is highlighting how thoughtful design not only removes barriers but also improves overall usability. Accessibility, in this view, is not a limitation but an enhancement that broadens functionality and convenience.

Examples of this principle can be found everywhere. Curb cuts, originally made for wheelchair accessibility, are now widely appreciated by parents with strollers, travelers with luggage, and delivery workers. Similarly, voice recognition software, developed to assist people with mobility or vision impairments, has become a mainstream tool used in smartphones, cars, and smart home devices. Norman’s insight is that designing with universal usability in mind produces innovations that serve a much wider audience.

The origin of this quote lies in Norman’s work as a cognitive scientist, designer, and author of influential books such as The Design of Everyday Things. His career has focused on how people interact with technology and how thoughtful human-centered design can bridge the gap between complexity and usability. By drawing attention to accessibility, Norman advocates for a shift in perspective: rather than seeing it as a niche requirement, designers should view it as a driver of broader improvement.

Ultimately, Norman’s statement reinforces the idea that good design is inclusive design. By considering the needs of those with disabilities, designers naturally create solutions that enhance comfort, efficiency, and usability for everyone. It is a reminder that accessibility should not be treated as an afterthought but as a core value in the design process, shaping products that truly work for the widest range of people.
