Study Notes

Design Thinking

Design thinking is a methodology for building projects from start to finish.
It is a human-centered, non-linear, and iterative process.
Designers and others use it to understand users, challenge assumptions, redefine problems, and create innovative solutions.

Design Thinking - Key Concepts

Human-centered: Focuses on understanding and meeting human needs.
Non-linear: Steps don't always follow a strict sequence; designers can revisit steps.
Iterative: The process repeats and refines solutions based on testing and feedback.
Integrative approach: Balances human needs, technical feasibility, and economic viability for broader challenges.
Context of Design: Drawing on historical figures (examples Brunel) to understand and solve complex design problems.
Human-Centered Design: Prioritizes human needs, cultural understanding, and context; applying it to global challenges.
Prototyping for Innovation: Uses rapid prototyping to quickly refine ideas and test solutions.

Tim Brown Ted Talk

The speech emphasizes human-centered design and systemic problem-solving over superficial product improvements.
Design thinking is a method to create more impactful innovations by focusing on improving the usability and accessibility of user-friendly products.

Design Thinking in a Nutshell

It combines desirability, feasibility and viability
Allows people not trained in design to use creative tools to solve challenges.
A detailed methodology for solving complex problems.

Main Stages of Design Thinking

Inspiration: Generating initial ideas and brainstorming possible solutions.
Ideation: Selecting the most feasible ideas and refining the solutions.
Implementation: Putting the chosen solutions into practice.

Design Thinking Process

Empathize: Understanding the user's perspectives, needs, and motivations.
Define: Clearly defining the problem that needs to be solved.
Ideate: Brainstorming multiple possible solutions.
Prototype: Creating a tangible representation of a solution to test its feasibility.
Test: Testing the prototype and gathering feedback from users to refine the design.

Web Design

Web design: A process of conceptualising, planning and creating the visual layout and functionality of websites.
Disciplines: Includes graphic design, UI/UX design and coding.
Key Elements:
- Visual elements: Layout, color, fonts, logos, images, videos, icons, shapes and user psychology.
- Functional elements: Navigation, information architecture, user interaction, speed, responsiveness, usability and accessibility.

Web Design Evolution

Responsive Design: Adapting website layouts to different screen sizes (phones, tablets, desktops) for a seamless user experience.
System-Centered vs User-Centered: A system-centric approach focuses on the technical aspect of the system while a user-centered design centers around user needs.

User-Centered Design

UCD: An iterative process focusing on user needs and testing during design iterations.
Characteristics: Empathy, usability testing, iterative process, accessibility, and personalization.
Steps: Understand the problem, specify user needs, design solutions, evaluate the solutions.

User Psychology

User behaviors and insights: Understand how users navigate and process information in web design.
Emotional impact: Use color and design elements to create the right emotions or sensations in the user.
Decision making: Applying principles like reciprocity and fear of missing out to increase user engagement and encourage interaction.
Eyetracking studies: Monitor where and how long users look at different parts of a webpage, revealing their pattern of visual navigation.

Color Psychology

Colors evoke emotions, influence user behavior, and are crucial for user experience.
Each color has an associated emotional impact (e.g., red = passion, blue = trust).
Cultural significance of colors varies across cultures.

Color Pairing Types

Monochromatic: Using different shades of the same color.
Complementary: Using colors opposite each other on the color wheel.
Analogous: Using colors adjacent to each other on the color wheel.
Split-complementary: Using a color and the two colors adjacent to its opposite.
Triadic: Using colors equally spaced around the color wheel.
Tetradic (or Double Complementary): Using two pairs of colors that are opposite each other on the color wheel.

Visual Hierarchy

Visual hierarchy is a principle for guiding user attention by using size, color, and positioning to communicate the importance of website elements.

Typography

Typography is essential for readability and creating visual hierarchy.
A proper combination of fonts enhances the appearance and readability of web content.

60/30/10 Rule

A guideline in design for creating visual clarity and emphasis by dividing the color palette into proportions for different elements. (60% for dominant color, 30% for secondary color and 10% for accents).

Data Storytelling

Fundamentals: Transforming complex data into accessible narratives.
Application: Simplifying data, enhancing memorability, and influencing audiences effectively.
Elements: Narrative, visualization, and data (supporting the story).

Web Design Steps

Research: Understanding users, competitors, goals.
Wireframing: Creating a simplified structure.
Design: Developing the look and feel.
Development: Building the website.
Testing: Ensuring functionality and usability.
Launch: Making the website live.
Maintenance: Keeping the website updated.

Key concepts in WordPress

Theme: Pre-designed templates for a website’s appearance.
Plugins: Extensions for adding features and functionalities.
Pages: Static content like 'About Us' or 'Contact'.
Posts: Dynamic content (e.g., blog posts) usually displayed chronologically.
Dashboard: The WordPress control panel.
Page Builder: Tools that allow customization of website layouts without coding.

Machine Learning

Supervised Learning: Models are trained on labeled data, predicting outcomes for new, unseen data based on learned patterns.
Unsupervised Learning: Models identify patterns and structures in unlabeled data without explicit guidance.
Reinforcement Learning: Models learn to make decisions in an environment by interacting with it and receiving rewards or penalties for their actions.

Additional Concepts

Deployment: Deploying a model to make predictions on new, unseen data.
Data Preprocessing: Cleaning and transforming data before use in machine learning.
Feature Selection: Choosing the most relevant features for a supervised model to maximize performance.
Model Evaluation: Assessing the performance of a machine learning model using metrics like precision, recall, F1 score.
Overfitting: A model that performs well on training data but poorly on unseen data.
Underfitting: A model that fails to capture the underlying patterns in the training data.

Network Science

A network is a collection of nodes and links (connections); nodes represent entities (e.g., people, cities, organizations).
Links (edges) represent relations (e.g., friendships, transactions, relationships).
Density: A measure of the interconnectedness of a network.
Centrality: Measures the importance of nodes in a network (e.g., closeness centrality, betweenness centrality).
Motifs: (meso-scale) Recurrent interaction patterns in networks.
Communities: Tightly connected clusters or groups of nodes (often found in social or biological networks).
Directed Networks: Networks with one-way connections (vs. undirected networks).
Weighted Networks: Networks where links have associated values (e.g., relationship strength).

Recommendation Systems

Collaborative Filtering: Recommending items based on the preferences of similar users.
Content-Based Filtering: Recommending items similar to those a user has liked previously.

Blockchain

Blockchain Technology: A distributed, immutable ledger recording transactions across many computers.
Cryptocurrencies: Digital money like Bitcoin and Ethereum.
Decentralization: Removes the need for a central authority, for instance, the banks or credit card companies.
Immutability: Ensures data integrity and prevents tampering.
Transparency: Allows all participants to see the transactional history.
