Design Goals

Today, we start with the first principle: Equitable Use. This means that a design should be marketable to people with diverse abilities without any segregation. Can anyone give an example?

What about automatic doors? They help everyone, right?

Exactly! They serve both those with and without disabilities conveniently. Remember, the goal is to ensure that safety and privacy are equally available for all users. What can we think about accessibility in our daily lives?

How about ramps for wheelchairs at building entrances?

Perfect! That's a great example of equitable use in architecture. Let's keep this in mind as we discuss the next principle.

What was the principle goal again?

To avoid segregation and provide equal means of use. Now, let’s move on to Flexibility in Use.

Now we’ll discuss Flexibility in Use. Can someone tell me what this principle means?

I think it means you can use something in different ways, like both right-handed and left-handed people can use it.

Well said! This principle provides choices in methods of use. For instance, ATM machines can have tactile keypads and audio output. Does everyone understand why this is helpful?

Yes! It helps those who might not see the screen or press the buttons easily.

Exactly! Flexibility reduces frustration and improves user experience. Are there any other examples of flexibility you can think of?

What about handrails on both sides of a staircase?

Excellent answer! This contributes to both comfort and safety. Remember, next time we're designing something, incorporating flexibility is essential.

Let’s now focus on Simple and Intuitive Use. Why do you think simplicity matters in design?

Because it makes things easier for everyone, right? Like easy-to-read signs?

Exactly! Elimination of unnecessary complexity is critical. We can use pictograms that apply across different languages. Can anyone think of an effective way to use signs?

Maybe using bright colors and clear symbols?

Yes! It maximizes comprehension and usability. So, remember, using visual feedback can simplify interactions immensely. Now let’s recap.

Can you remind us of the key point here?

The goal is to design for ease of understanding, for every user's experience, knowledge, and skills.

Next is Perceptible Information. Why do we need to think about how we communicate information through design?

Because not everyone can see or hear the same way?

Absolutely! Designs should use multiple modes to present essential information. Can someone give examples of this?

Like tactile paving for visually impaired people?

Precisely! Also, contrasting colors on signs can help those with visual impairment. Let’s remember this principle emphasizes effective communication to ensure user needs are met.

We’re wrapping up with Tolerance for Error. This principle is about minimizing hazards. Why do you think this is critical?

To keep people safe, I guess?

Exactly! It’s important to arrange elements to encourage safety. Do anyone have situations where we see this?

Railings on high walkways?

Perfect! Such features help prevent accidents. Always remember—good design is as much about preventing mistakes as about utility.
