Student Feedback
“I’ve always been decent at programming side of things, but never so good at thinking about the user side of things, you’ve definitely given me a better idea of how to tackle programming challenges and how to make sure that they reflect good usability as well particularly due to my enjoyment of web development and I will also begin to focus more heavily on mobile development as well I think. I am glad the subject was for early on and not later in the degree. ”

What Sem 1 2021 students think about UCD course
“”The best aspects are learning how to use prototyping programs such as figma to create tangible products that we can display in a portfolio.
Learning about what makes good and bad UX design was also very interesting and it was very eye opening to see how things are designed in every day life.”
“Through this course, I learned how to analyze user requirements and understand how to make a project that satisfies users, which is very practical for me if I want to be involved in application development in the future..”
“This course has some very fun aspects to it, designing applications is definitely one of them. Course material is made fun to learn with heaps of real life examples which helps to remember it..”
“”I love the wall of fame or shame. It really helps me to understand the content better and interact with the course more.
Also during lectorials, I enjoy having opportunities to contribute to discussions and I also enjoy group tasks.
The assessment tasks are explained in a concise way which helps me to understand the requirements.”

Introduction to Usability and UCD

Today’s Learning Objectives
• To understand what is User Centred Design (UCD)
• To understand where does it fit in the usability sphere. • To understand its relevance in the industry.

Why Design?
The Design of Everyday Things by
(Professor of Cognitive Science & Computer Science)

What is Usability?
A trending word in today’s IT development and design circles? Is in fact one of the oldest concepts.
According to ISO, it is defined as “The extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use.”

What is Usability?
’s definition of usability
“Usability is a quality attribute that assesses how easy user interfaces are to use. The word “usability” also refers to methods for improving ease-of-use during the design process”.
https://www.nngroup.com/articles/usability-101-introduction-to-usability/

Nielsen’s Components of Usability
•Learnability: How easy is it for users to accomplish basic tasks the first time they encounter the design?
•Efficiency: Once users have learned the design, how quickly can they perform tasks? •Memorability: When users return to the design after a period of not using it, how
easily can they re-establish proficiency?
•Errors: How many errors do users make, how severe are these errors, and how easily can they recover from the errors?
•Satisfaction: How pleasant is it to use the design? https://www.nngroup.com/articles/usability-101-introduction-to-usability/

’s Attributes of Usability
• Useful: Does it do something people need done?
• Learnable: Can people figure out how to use it?
• Memorable: Do they have to relearn it each time they use it?
• Effective: Does it get the job done?
• Efficient: Does it do it with a reasonable amount of time and effort? • Desirable: Do people want it?
• Delightful: Is using it enjoyable, or even fun?

Let’s make a distinction
Usability is not UCD
Usability is a result, goal, a field (UE, UX) UCD is a methodology
Usability is an outcome of UCD process

Some definitions
From Lowdermilk’s book, User-centered design:
•HCI focuses specifically on humans interacting with computing products.
•UCD is a methodology used by developers and designers to ensure they’re creating products that meet users’ needs.
•UX is one of the many focuses of UCD. It includes the user’s entire experience with the product, including physical and emotional reactions.

Which comes first? The UI or UX?
The chicken and egg of UX and UI, https://www.youtube.com/watch?v=2wZUTe70w1Y

The ubiquitousness of usability…
• Usability is everywhere. The practice pervades itself in every tool,
object you can use.
• The very design of a lecture hall (or your room), to
• the smartphones you are using right this moment, to
• the facebook status updates you are now checking, to • the quick lock buttons on your phones
• the swipe feature on your app

Usability is not just design
• Your websites being pretty is not the main goal here.
• It is not merely concerning the aesthetics
• The value of aesthetics change
• Like other things, your product can be pretty and flashy but is difficult to use.
• Remember: Flash animations?

Our public transport friend
Count the number of arrows in this picture.
How long did it take for you to learn how to use this machine?
How long do you think it would take an elderly?
Would you rather top up your card at 7- 11?

Consider another Melbourne staple
• Specifically, the old types where you had to pull an overhead cord if you wanted get off at the next stop.
• How did you learn that?
• Did you see someone else doing
• Or did you pull and see what happens.

The App Gen Z Says They Can’t Live Without

Engagement
Empowerment
How well a product communicates with the user on:
How to use me
How to use me to achieve your task
How well do you understand my role in achieving your goal.

Norman doors don’t signify the right affordance .
When users perceive the doors, they often develop a mismatched mental model of how the door works

Affordance
First coined by . Gibson as:
all “action possibilities” latent in the environment, independent of an individual’s ability to recognize them, but always in relation to agents (people or animals) and therefore dependent on their capabilities
appropriated the term for HCI.
Norman’s affordances “suggest” how an object may be interacted with.
(Wikipedia & The Design of Everyday Things)

 Do not care about technical details, not quite
 They used to, but user population has exploded to cover the
general population
 Sometimes does not know what they want
 How do we design for them?

Because the goal is…
To create a better user experience
To continually work with users to understand what works best
User Centred Design
• Is a process to improve usability
• To remove as much guess work
as possible
• To work from the perspective of the user whenever it is relevant to do so

What UCD is Not
• Not a bug report
• Not a waste of resources
• It is not only a reactive process.
UCD is in fact
• Anticipation of user’s needs
• saves more time and money
• Reduces the probability of redesign later on
• Streamlines the testing phase of development
• more effective when proactive. Do listen to users, watch them 50

Programmers and UCD
• As programmers it is always tempting to seek out the HOW
• However we should ask WHY
• Implementing something cool is always great if you are always the only user. • The quick and easy way to code things often leads to poor usability
• Excel 2003
“The sheet you are copying contains cells that have more than 255 characters in them. Copying an entire sheet truncates cells that contain more than 255 characters. To avoid truncation, copy the cells of the source sheet to the destination (rather than copying the entire sheet).”

It’s not just the users…
• Those commissioning your app have no idea what they want • What do you do?
