Activity-centered design focuses on the behavior surrounding particular tasks. Users still play a significant role, but it is their behavior rather than their goals and needs that is important.

Activity-Centered Design

Inclusive design "empowers designers to create products whose experiences serve as many people as possible."  It is a design process that seeks to create products that are accessible to all, no matter their background.

Inclusive Design

Designs can affect a wide range of people, so it's important to follow principles of ethical design:

-Usability

-Accessibility

-Privacy

-Transparency & Persuasion

-User Involvement

-Focus

-Sustainability

Ethical Design

According to World Health Organization, "one in 160 children has an autism spectrum disorder (ASD)."(WHO, 2019). ASD affects people’s ability in communication and behavior, and an autistic designer, Irina Rusakova comments that “they feel most comfortable online — learning, communicating, shopping, and gaming” (Rusakova, 2020). She also mentions that products designed for autistic users should accommodate their needs instead of trying to fix or change their habits and emphasizes the importance of “clear visual structure and consistent layout for similar types of information” in the UI design for autistic people (Rusakova, 2020).

Industrial design(ID) is the practice of designing and developing ideas for product optimization, such as value, function, system, and appearance, to benefit both users and manufacturers. The focuses of ID include intuitive creativity and the scientific decision-making process. Some examples of ID are iPod and Chair by Charles Eames. It aims to identify the strengths and weaknesses of competitors and helps to discover the competitive edges and shortcomings of a given product.

Product design is the process that is utilized to combine the needs of both users and business goals to create successful products. Product designers use their work to ensure that products are suitable for the company’s long-term business needs. They work to define product goals, create product roadmaps, and ultimately help release a successful product. The main difference between product design and UX design is that product designers are focused on the brand’s product in the market over time. 

Product Design

To create a successful product, there are three levels of emotional design:
1. Visceral design: an immediate, deep-level gut reaction to the product. It’s the first impression.
2. Behavioral design: the product has to feel good, look good, and perform well. It’s about how the product, structure, or system, as viewed by the users, meets their needs and requirements.
3. Reflective design: it’s about self-image, personal satisfaction, memories, reflecting back on the experience.

Emotional Design

Systems design is a structured, rigorous, and holistic design approach that focuses on context and is particularly appropriate for complex problems. In systems design, it is the system (that is, the people, computers, objects, devices, and so on) that the center of attention, while the users' role is to set the goals of the system.

Systems Design

Genius Design relies largely on the experience and creative flair of a designer. Jim Leftwich, an experienced interaction designer interviewed by Dan Saffer (2010, pp. 44–45), prefers the term "rapid expert design." In this approach, the users' role is to validate ideas generated by the designer, and users are not involved during the design process itself.

Genius Design

Various types of design and design approaches include:
- Activity-Centered Design
- Designing for Autistic People
- Emotional Design
- Ethical Design
- Genius Design
- Inclusive Design
- Industrial Design
- Product Design
- Systems Design

The designing of interactive products, environments, systems, and services. Common topics include design, human–computer interaction, and software development. A central concern of interaction design is to develop interactive products that are usable, easy to learn, effective to use, and provide an enjoyable user experience to support and enhance the way people communicate and interact in their everyday lives.  Dan Saffer (2010) suggests four main approaches to interaction design, User-centered design, Activity-centered design, Systems design, and Genius design.

Interaction design

Graphic design is the process of visual communication and problem-solving through the use of typography, photography, iconography and illustration. The field is considered a subset of visual communication and communication design, but sometimes the term "graphic design" is used synonymously. Graphic designers use typography, visual arts, and page layout techniques to create visual compositions. Common applications of graphic design include corporate design (logos and branding), editorial design (magazines, newspapers and books), wayfinding or environmental design, advertising, web design, communication design, product packaging, and signage.

Graphic Design

Similar in structure to causal diagrams (i.e. nodes with connections), except the connections are not causal. Nodes contain concepts are organized
in a hierarchy (such as in 1Cademy's knowledge graph).

A narrow definition
of interaction design is:
“The design of the subjective
and qualitative aspects of
everything that is both digital
and interactive.”

A broad definition
of interaction design is:
‘The design of everything that is
both digital and interactive.”

Don Norman is the director of the newly established (2014) Design Lab at the University of California, Co-founder of the Nielsen Norman group and Honorary Professor at Tongji University (Shanghai) in their College of Design and Innovation. The term user-centered design came from him in his book The Design of Everyday Things (1988). It marked a shift from the previous term “user centered system design” where instead of focusing on the system itself and the aesthetics of the interface, Norman concentrated on user needs.

Process of solving a product design problem: 
1. Understand your goal (Why) 
2. Define the audience (Who) 
3. Understand customer’s context (When/Where) and needs 
4. List ideas (What) 
5. Prioritize and choose an idea 
6. Solve 
7. Measure success (How)

Design thinking is a process that works to solve problems in a user-centric way. It has a strong focus on users and humans, to ensure that solutions meet their needs.



Steps to design thinking:

1. Empathize: Understand your users

2. Define: Clearly define the problem and their needs

3. Ideate: Brainstorm potential solutions, create ideas

4. Prototype: Build your solutions

5. Test: Test out your solutions

Design Thinking

I feel that this statement, "Dan Saffer (2010) suggests four main approaches to interaction design, User-centered design, Activity-centered design, Systems design, and Genius design." should be linked as a child node rather than grouped together into this. There is a lot of content in this node and could be made more clear by breaking it down further into more granular content

In software development and computer science, ubiquitous computing refer to the idea of computing could be and is made to appear anytime and everywhere. Reflecting to Interaction design and User Experience Design, the term is refer to the idea that user interaction could be in many forms, from laptop computers, phones to everyday objects such as lamps and glasses.

Gestalt principles are laws of human perception that describe how we group similar elements, recognize patterns, and simplify complex images when we perceive objects. These principles include Proximity, Similarity, Continuity, Closure, Symmetry, Figure/Ground, and Common Fate. Understanding these concepts can be enhanced by observing them in real-world examples.

Types of Design

According to Bill Moggridge in *Designing Interactions*, the core skills of interaction design include:

1. Synthesizing a solution from all relevant constraints, understanding everything that will make a difference to the result.
2. Framing, or reframing, the problem and objective.
3. Creating and envisioning alternatives.
4. Selecting from those alternatives, knowing intuitively how to choose the best approach.
5. Visualizing and prototyping the intended solution.

Core Skills of Interaction Design

When designing for interaction, designers ask key questions to ensure a successful user experience. These core considerations include defining how the user physically interacts with the interface, providing visual clues about behaviors before actions are taken, anticipating and mitigating errors, optimizing system feedback and response time, adhering to strategic standards, and simplifying for learnability.
