Even in the age of AI, what ultimately matters is 'human experience'.

New technologies continue to emerge.
The Internet changed services, and mobile changed daily life.
AI is now changing the way we work, search, choose, and use things again.

However, there is something that does not change.

People still want to save time.
They want to get what they want with less effort.
They want to understand complex processes easily.
They want to choose an experience that suits them.

Even if technology changes, experience does not disappear.
So, UX design will not disappear either.

In fact, it becomes even more important in the AI era.
Amidst more features, more automation, and more touchpoints The ability to determine what constitutes a truly valuable experience for the userThis is because it became necessary.

UX design is not about making the screen look pretty.

UX design covers the entire process of users encountering, understanding, selecting, acting upon, and remembering a service.

Why do users drop out at this stage?
Why do some functions feel difficult to understand?
Why do people act differently from what they say?
Why is the same service convenient for some people but inconvenient for others?

To create a good experience, you must understand people.
You need to know how people think, judge, remember, and feel emotions.
And you must be able to observe actual user behavior, interpret data, and structure problems.

This book is a UX design standard that organizes that knowledge into a single flow.

If you have ever had such concerns, you need this book.

“I know that UX design is important, but I don't know exactly what to study.”

“I've seen a lot of methodologies, but I don't know how they connect to actual work.”

“Even after conducting user research, I am at a loss as to how to interpret the results.”

“I am asked to define the customer's problem, but it is difficult to distinguish what the real problem is.”

“I have the data, but I don't know what decision to make.”

“I am wondering what capabilities UX designers should possess in the AI era.”

This book is not a list of trendy methodologies.
It feels difficult and ambiguous ‘A book that organizes the concept of 'experience' into an understandable structureno see.

Understanding experience allows you to create better products.

A good product is not just a product with many features.
It is a product that fits the user's situation, is easy to understand, encourages natural behavior, and makes them want to use it again.

To achieve this, it is insufficient to handle the user experience solely through the senses.

How do people receive information?.
When do you feel tired?.
Why judge intuitively?.
At what moment do you feel satisfied?.
What problems do you spend money and time on?.
At what point in the service does the experience break?.

UX design becomes more powerful when you can answer this question.

This book explains UX design by dividing it into 'people' and 'research'.

To do UX design well, you need two things.

First, knowledge for understanding people and experiences.
Second, a method for investigating and interpreting actual users.

So, this book is largely UXand UX researchIt consists of.

1. UX — How People Experience

The UX part covers the basic principles of creating experiences.

We examine the history and structure of UX design and summarize how people think and behave when using products.

We understand users' cognition, judgment, memory, and emotions based on cognitive psychology, behavioral economics, and HCI.
We examine when users feel something is complex, why they make intuitive judgments, what experiences they remember, and how emotions influence the product experience.

UX is not just a simple methodology A perspective on understanding peopleWe will summarize it as follows.

2. UX Research — How to Understand Users

The UX Research part covers how to investigate and interpret actual users and their experiences.

This summarizes when research should be conducted, what can be gained from it, and how to separate attitude and behavior data.

It covers methods for asking users directly, observing from the side, tracking traces of behavior, and discovering flows within the service.

It also covers how to interpret qualitative and quantitative data, how to segment users, and how to define problems and determine priorities.

UX research is not just a simple interview technique Thinking tools for determining product directionExplained as.

What you can gain from this book

• You can structurally understand what UX design deals with.
• You can understand the influence of human cognition, judgment, memory, and emotion on experience.
• You can organize when, why, and how user research should be conducted.
• You can establish criteria for distinguishing between qualitative and quantitative data and interpreting them.
• You can define user problems more clearly.
• You can gain a deeper understanding of the user journey and UX flow.
• You can summarize the essence of UX design that remains valid even in the AI era.

I recommend this to people like this.

• For those who want to systematically organize UX design from the beginning
• For those who want to understand user experience more deeply as a product designer
• For those who want to go beyond UI and cover product flow and problem definition
• Designers who want to connect UX research to practice
• For those who are at a loss regarding user interviews or data interpretation
• For those who want to better design customer experiences as planners, PMs, or founders
• For those who want to redefine the role of UX design in the AI era

This book is not this kind of book.

• This is not a book that merely lists trendy UX methodologies.
• This is not a research template book containing only interview questions.
• This is not a portfolio reference book that displays flashy examples.
• It is not a book that explains UX based on intuition.
• This book is designed to organize the concepts necessary to understand experience and to establish criteria for viewing actual users and problems.

Why UX Design Is Still Necessary in the AI Era

AI can produce more results.
However, you still have to decide which experience is better for the user.

Whether automated features are really convenient.
Whether users can trust the results of the AI.
At what moments a person must take direct control.
Which experiences save time, and which actually increase the burden.

This question cannot be solved by technology alone.
You must understand the person to answer.

As long as experience exists, UX design will not disappear.
This book is a starting point for better understanding and designing that experience.
