- Inclusive design: A methodology that enables and draws on the full range of human diversity. It moves beyond accessibility minimums to proactively include users of all ages, abilities, cultures, and backgrounds. This approach recognizes that exclusion is often unintentional and seeks to remove barriers before they appear.
- Core principle: Recognize diversity and uniqueness. Instead of designing for an average user, inclusive design acknowledges that each person has a unique combination of characteristics. Products should be flexible enough to adapt to individual preferences and needs without requiring special adaptation.
- Difference from accessibility: Accessibility focuses on making products usable by people with disabilities, often as a compliance requirement. Inclusive design is broader, aiming for universal usability across all demographics. Accessibility is a subset of inclusive design, but inclusive design also addresses age, language, economic status, and more.
- User exclusion: When designers assume a narrow set of user traits, they inadvertently exclude others. For example, a mobile app that requires fine motor control excludes users with tremors. Inclusive design challenges these assumptions by considering edge cases from the start.
- Benefits for all: Features designed for inclusivity often improve the experience for everyone. Curb cuts on sidewalks, originally for wheelchair users, also benefit parents with strollers and delivery workers. Similarly, captions on videos help people in noisy environments or non-native speakers.
- Designing for one, extending to many: A popular inclusive design strategy is to focus on a specific underserved group and then extend solutions to broader audiences. For example, designing for users with low vision can lead to high-contrast themes that benefit outdoor use even for typically sighted users.
- Three dimensions: Inclusive design considers three dimensions: recognizing diversity, understanding user context, and ensuring equitable participation. Each dimension helps designers avoid creating barriers based on ability, situation, or identity.
- Getting started: Begin by challenging your own assumptions. List the personas you typically design for and then identify who might be left out. Engage with diverse users early in the process to uncover hidden barriers.
- Co designing with users: Inclusive design is most effective when users from diverse backgrounds are involved as co designers rather than test subjects. This participatory approach ensures that solutions are grounded in real lived experiences and reduces the risk of making assumptions. It also builds empathy within design teams and leads to more innovative outcomes.
- Iterative evaluation: Inclusive design requires continuous testing with a wide range of users throughout the development process. What works for one group may create new barriers for another. Regular feedback loops with people of different ages, abilities, and contexts help identify unintended exclusion and allow for timely adjustments. This iterative cycle is critical for achieving truly inclusive products.
Design Principle
Principle: Solve for one, extend to many
Definition: Design for a specific excluded group first, then evaluate if the solution benefits a wider audience. This approach ensures deep consideration of real needs rather than hypothetical averages.
Application: When designing a mobile interface for a banking app, start by making it usable for a user who is blind. That means ensuring all information is conveyed audibly through a screen reader, buttons are clearly labeled, and navigation is linear. The resulting app will also be easier for sighted users to navigate quickly and for those with cognitive impairments.
Quick Revision
- Inclusive design proactively includes the full range of human diversity, beyond just disability.
- It differs from accessibility by addressing age, language, culture, and economic status.
- Features designed for edge cases often improve usability for all users.
- The principle 'solve for one, extend to many' is a practical starting strategy.
