The Principles of Universal Design is intended to guide a wide range of design disciplines, including environments, products, and communications. Here we have seven principles of universal design. If you have ever considered to deign it, check out below.
- Equitable Use
The design is useful and marketable to people with diverse abilities.
1a. Provide the same means for all users: identical whenever possible; equivalent when not.
1b. Avoid segregating or stigmatizing any users.
1c. Provisions for privacy, security, and safety should be equally available to all users.
1d. Make the design appealing to all users.
- Flexibility in Use
The design accommodates a wide range of individual preferences and abilities.
2a. Provide choice in methods of use.
2b. Accommodate right or left handed access and use.
2c. Facilitate the user’s accuracy and precision.
2d. Provide adaptability to user’s pace
- Simple and Intuitive
Use of the design is easy to understand, regardless of the user’s experience, knowledge, language skills, or current concentration level.
3a. Eliminate unnecessary complexity.
3b. Be consistent with user expectations and intuition
3c. Accommodate a wide range of literacy and language skills.
3d. Arrange information consistent with its importance.
3e. Provide effective prompting and feedback during and after task completion.
- Perceptible Information
The design communicates necessary information effectively to the user, regardless of ambient conditions or the user’s sensory abilities.
4a. Use different modes (pictorial, verbal, tactile) for redundant presentation of essential information.
4b. Provide adequate contrast between essential information and its surroundings.
4c. Maximize “legibility” of essential information
4d. Differentiate elements in ways that can be described (i.e. make it easy to give instructions or directions).
4e. Provide compatibility with a variety of techniques or devices used by people with sensory limitations.
- Tolerance for Error
The design minimizes hazards and the adverse consequences of accidental or unintended actions.
5a. Arrange elements to minimize hazards and errors: most used elements, most accessible elements; hazardous elements eliminated, isolated, or shielded.
5b. Provide warnings of hazards and errors.
5c. Provide fail safe features.
5d. Discontinue unconscious action in tasks that require vigilance.
- Low Physical Effort
The design can be used efficiently, comfortably and with minimum of fatigue.
6a. Allow user to maintain a neutral body position.
6b. Use reasonable operating forces.
6c. Minimize repetitive actions.
6d. Minimize sustained physical effort.
- Size and Space for Approach and Use
Appropriate size and space is provided for approach, reach, manipulation, and use regardless of user’s body size, posture, or mobility.
7a. Provide clear line of sight to important elements for any seated or standing user.
7b. Make reach to all components comfortable for any seated or standing user.
7c. Accommodate variations in had and grip size.
7d. Provide adequate space for the use of assistive devices or personal assistance.
