The probability of developing products and environments that are accessible for everyone lies within the concept of universal design. There are seven principles of universal design that serve as a foundation for designers and Human Factors practitioners that help make usable interfaces for all people no matter what age, technical expertise, or physical ability.
Equitable use, states that usable and accessible design is provided for people with a wide range of abilities.
Flexibility in use, aims to accommodate to user’s preferences and abilities.
Simple and intuitive use, seeks to create easy-to-understand design solutions for a variety of users who all possess different knowledge, experience, language abilities, and more.
Perceptible information, states that design solutions portray information clearly and effectively to the user.
Tolerance for error, promotes design that minimizes hazards resulting from user error.
Low physical effort, asks designers to develop designs that maximize comfort and minimize the discomfort that can result from too much physical exertion or unnatural body positioning.
Lastly, size and space for approach and use, states that users are provided with appropriate size and space for approach when interacting with a design.
