Equitable Use
Unlock Audio Lesson
Today, we're starting with the first principle of Universal Design: Equitable Use. This principle ensures that design is useful and marketable to everyone, regardless of their abilities.
Can you give us an example of what that looks like?
Certainly! For example, an automatic sliding door provides the same means of entry for everyone, whether they are walking, using a wheelchair, or carrying items. This eliminates segregation.
So, it's about making sure no one feels excluded?
Exactly! And to remember this concept, think 'EE' for Equitable Use, meaning everyone experiences the same usability.
That's a great way to remember it! What about privacy and safety?
Good question! Privacy and security features should also be equally accessible, which is vital for inclusivity.
Can we summarize this principle?
Sure! Equitable Use ensures designs are accessible and beneficial for all, avoiding any segregation or stigmatization.
Flexibility in Use
Unlock Audio Lesson
Now, let’s move on to the second principle: Flexibility in Use. It means designs should adapt to a wide range of individual preferences.
How does that apply in real life?
An example would be classrooms with flexible furniture arrangements, which allow students to set up their learning space in a way that suits their needs.
So, accommodating both right and left-handed users is part of this too?
Exactly! That's a key feature of flexibility. It’s also about not forcing everyone into the same mold.
What’s a good way to remember this principle?
Think of 'FF' for Flexibility in Use, which signifies that the design is both functional and adaptable.
Can you recap the key points?
Sure! Flexibility in Use means that the design accommodates a variety of preferences and abilities, ensuring a user-centric approach.
Simple and Intuitive Use
Unlock Audio Lesson
The third principle we need to understand is Simple and Intuitive Use. This means that a design should be easy to understand for all users.
Can you elaborate on what 'easy to understand' entails?
It means eliminating unnecessary complexity and using clear, consistent cues. For instance, a public kiosk could have touch screen icons that are simple to navigate.
What if someone has low literacy skills?
Great question! The design can still include audio feedback and pictorial guides, catering to different literacy levels.
What memory aid can we use here?
You can use 'SIMPLE' as an acronym to remind us: Straightforward, Intuitive, Minimal Complexity, Legible & Easy!
And how would you summarize this principle?
To sum it up, Simple and Intuitive Use means designs must be understandable and usable, regardless of the user's background or experience.

Detailed
The Seven Principles of Universal Design
Universal Design (UD) aims to create environments and products that are usable by everyone, irrespective of their age, ability, or status. The principles outlined here serve as a foundation for evaluating and improving design practices.
- Equitable Use: Designs must provide the same means of use for all users, avoiding segregation and ensuring equal access to essential services.
- Example: Automatic sliding doors are useful for everyone, not just those with disabilities.
- Flexibility in Use: Designs should accommodate a variety of individual preferences and abilities, allowing for customized use to meet diverse needs.
- Example: Movable furniture setups in classrooms let students arrange their workspace according to their preferences.
- Simple and Intuitive Use: A design is to be easy to understand, catering to various levels of experience and cognitive abilities.
- Example: Kiosks that feature simple icons and audio feedback accommodate users with lower literacy or visual impairments.
- Perceptible Information: Necessary information should be effectively communicated to users through multiple modes (visual, auditory, etc.), useful for those with sensory disabilities.
- Example: Emergency alarms that use both lights and sounds to alert individuals.
- Tolerance for Error: Designs should minimize hazards and offer fail-safe features to reduce the consequences of mistakes.
- Example: Software prompts that confirm deletion actions prevent accidental loss of data.
- Low Physical Effort: Services must be usable efficiently, requiring minimal fatigue.
- Example: Lever handles on doors are easier to operate than traditional knobs.
- Size and Space for Approach and Use: Adequate space must be available, accommodating all users regardless of their size, posture, or mobility.
- Example: Kitchen designs with accessible appliances for both standing users and wheelchair users.
These principles aim to enhance the user experience and ensure inclusivity within public spaces and products.

Definition: The design is useful and marketable to people with diverse abilities.
Key Features:
- Provides the same means of use for all users.
- Avoids segregating or stigmatizing any users.
- Provisions for privacy, security, and safety are equally available to all.
Example: A building entrance with an automatic sliding door that serves everyone equally, without a separate door for wheelchair users.
Detailed Explanation
Equitable use means that everyone can access and use a design or environment, regardless of their abilities. This principle emphasizes that designs should not isolate or stigmatize any group of users. For instance, all users should have the same way to enter a building without feeling different or separate. If a building provides an automatic sliding door, everyone—including those with mobility issues—can use it without facing barriers.
Examples & Analogies
Think about a restaurant with an accessible entrance. Instead of having stairs that some customers can’t use, they have a ramp. This ramp allows everyone, whether they are on foot, in a wheelchair, or pushing a stroller, to enter easily and enjoy their meal together. The design does not differentiate between users but welcomes all equally.
Flexibility in Use

Definition: The design accommodates a wide range of individual preferences and abilities.
Key Features:
- Provides choice in methods of use.
- Accommodates right- or left-handed access and use.
- Facilitates user's accuracy and precision.
Example: A classroom with movable furniture that allows students with and without disabilities to customize their workspace.
Detailed Explanation
Flexibility in use means that a design can adapt to different needs and preferences. This is important because people learn and work in various ways. For example, if furniture in a classroom can be rearranged, it allows all students to arrange their space in a way that works best for them, whether they are right-handed or need to work standing up or sitting down.
Examples & Analogies
Imagine a kitchen where all the cabinets can be configured differently. This allows someone shorter or in a wheelchair to adjust the height of shelves to their liking. Just like a kitchen, flexible spaces allow each person to customize their environment to better fit their needs and improve their experience.
Simple and Intuitive Use

Definition: Use of the design is easy to understand, regardless of the user's experience, knowledge, language skills, or concentration level.
Key Features:
- Eliminates unnecessary complexity.
- Accommodates a wide range of literacy and language levels.
- Provides clear and consistent cues.
Example: A public kiosk with touch screen icons and audio feedback for navigation by persons with low literacy or visual impairment.
Detailed Explanation
This principle focuses on making designs clear and straightforward. Complexity can confuse users, especially if they have different backgrounds or abilities. For example, a simple kiosk with easy-to-understand icons and audio cues ensures that everyone, from children to the elderly, can use it effectively without frustration.
Examples & Analogies
Consider a remote control for a TV. If it has too many buttons and complicated symbols, a person might struggle to figure out how to operate it. But if it has a few large buttons with clear icons (like a play button, pause button, and volume control), anyone can easily understand how to use it—just like a friendly guide showing the way.
Perceptible Information
Unlock Audio Book
Signup and Enroll to the course for listening the Audio Book
Definition: The design communicates necessary information effectively to the user, regardless of ambient conditions or the user's sensory abilities.
Key Features:
- Uses different modes (pictorial, verbal, tactile) for redundant presentation of essential information.
- Provides adequate contrast between essential information and its surroundings.
- Maximizes legibility of essential information.
Example: Emergency alarms that use both flashing lights and sound to alert people with hearing or visual impairments.
Detailed Explanation
Perceptible information ensures that important messages are accessible to everyone. This is vital in emergency situations where clarity can save lives. By using multiple formats—like sound, lights, and clear signs—a message can reach a broader audience, including those who might have impairments or be in challenging situations.
Examples & Analogies
Think of fire alarms that flash while making sounds. If someone can't hear the alarm, the bright flashing light will still get their attention, alerting them to the danger. Just like in a movie theater where emergency instructions appear on screen while also being verbally announced, this dual approach makes sure everyone understands without relying solely on one method.
Tolerance for Error
Unlock Audio Book
Signup and Enroll to the course for listening the Audio Book
Definition: The design minimizes hazards and the adverse consequences of accidental or unintended actions.
Key Features:
- Arranges elements to minimize hazards and errors.
- Provides warnings of hazards and errors.
- Allows fail-safe features.
Example: Software that provides an “undo” feature or a confirmation prompt before permanently deleting files.
Detailed Explanation
This principle emphasizes safety and reduces the likelihood of mistakes or dangerous situations. By anticipating user errors and creating ways to correct mistakes, designs become more user-friendly and reduce risks. For example, an 'undo' option helps people feel secure in their actions, knowing they can fix errors easily.
Examples & Analogies
Think of using a pen with a mistake-correcting feature—when you make a mistake, you can easily fix it rather than start again. Just like in situations where a bridge has clear warning signs or barriers to prevent accidents, tolerating errors creates a safer environment for everyone.
Low Physical Effort

Definition: The design can be used efficiently and comfortably and with a minimum of fatigue.
Key Features:
- Allows user to maintain a neutral body position.
- Uses reasonable operating forces.
- Minimizes repetitive actions and sustained physical effort.
Example: Lever-styled door handles that require minimal grip strength compared to traditional round knobs.
Detailed Explanation
This principle focuses on reducing the physical demands placed on users. By creating designs that require minimal effort, we ensure that more people can access and use them comfortably. Features like lever door handles, which can be pushed down rather than turned, are easier for everyone, especially those with strength limitations.
Examples & Analogies
Think of doors in public spaces with push bars instead of round knobs. When you can simply push a bar, it requires less effort than rotating a knob. This is similar to using a shopping cart instead of carrying heavy bags; the cart allows for easier transport without straining.
Size and Space for Approach and Use
Unlock Audio Book
Signup and Enroll to the course for listening the Audio Book
Definition: Appropriate size and space is provided for approach, reach, manipulation, and use regardless of user's body size, posture, or mobility.
Key Features:
- Accommodates people with mobility aids (e.g., wheelchairs, walkers).
- Provides adequate space for seating, standing, or movement.
- Ensures accessibility from both left and right sides.
Example: A kitchen layout with counters, switches, and storage reachable by both standing users and those in wheelchairs.
Detailed Explanation
This principle highlights the importance of providing sufficient space for everyone to interact with a design, regardless of their physical abilities or needs. It's about ensuring that layouts and designs consider diverse users, making them accessible without frustration or difficulty.
Examples & Analogies
Imagine a kitchen where a person using a wheelchair can easily roll up to the counter and reach all the necessary tools and appliances. If the space is planned with accessibility in mind—like having wide aisles and lower counters—every person can participate in cooking without encountering barriers, just like a well-designed park with paths easy for cyclists, pedestrians, and strollers alike.
