Don Norman proposes the emotional system consists of three different, yet interconnected levels, each of which influences our experience of the world in a particular way. The three levels are visceral, behavioral, and reflective. 

(1)The visceral level is responsible for the ingrained, automatic and almost animalistic qualities of human emotion, which are almost entirely out of our control. 
(2)The behavioral level refers to the controlled aspects of human action, where we unconsciously analyze a situation so as to develop goal-directed strategies most likely to prove effective in the shortest time, or with the fewest actions, possible. 
(3)The reflective level is, as Don Norman states, "...the home of reflection, of conscious thought, of learning of new concepts and generalisations about the world". 

These three levels, while classified as separate dimensions of the emotional system, are linked and influence one another to create our overall emotional experience of the world.

Norman's Three Levels of Design

Don Norman is an interaction-design figure and co-founder of the Nielsen Norman Group. In The Design of Everyday Things (1988), he emphasizes designing around users' needs rather than centering the system or interface aesthetics. He also proposed three interconnected levels of design: visceral, behavioral, and reflective.

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).

Design Disciplines

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.”


Narrow & Broad Definition of Interaction Design

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.

Design Techniques 

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.

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

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.

Interaction Design Considerations

A product-design problem-solving framework built on the journalistic 5W's and 1H: 1. Why – understand the goal. 2. Who – define the audience. 3. When/Where – understand the customer's context and needs. 4. What – list, prioritize, and choose an idea. 5. How – solve the problem and measure success.
