Study Notes

### Human Computer Interaction

Human-Computer Interaction (HCI) involves designing, evaluating, and implementing interactive systems for human use and studying related phenomena.
It focuses on the interaction between people (users) and computers.
The golden principle in HCI is "people should come first".

Components of HCI

Human: Individual or group of users.
Computer: Any technology from desktop computers to large-scale systems.
Interaction: Direct or indirect communication between humans and computers.

Goals of HCI

Improve the safety, utility, effectiveness, efficiency, and usability of systems involving computers.
Produce usable, safe, and functional systems.

Importance of HCI

Close competition in the market.
Easy comparison of products, impacting purchasing decisions.
Users who can't find or order products will not buy them.
HCI can prevent accidents and address health and safety concerns.
It can reduce customer training and support costs.
Direct correlation between HCI and sales.
HCI can offer job opportunities.

System Design Approach

Traditional Approaches: Focus on system functionality and efficiency.
User-Centered Approach (UCD): Emphasizes understanding users and their needs throughout the development process.

UCD Approach Steps

Data Collection: Gather information from users and stakeholders using various methods like interviews, questionnaires, and literature reviews.
Data Analysis: Analyze collected data to identify user needs, tasks, and system requirements.
Prototyping: Create interactive prototypes for user testing and feedback.
Design: Design the system based on user needs and feedback.
Evaluation: Evaluate the system's usability, functionality, and acceptability through expert and user testing.

Interaction Design: 5 Dimensions

Words: Language used to facilitate interaction and communication.
Visuals: Visual elements that complement the words and enhance user experience.
Objects/Space: Layout and placement of elements to create a context for interaction.
Time: The timeframe within which users interact with the system.
Behavior: Actions and reactions of users and the interface.

5 Pillars of Interaction Design

Goal-Driven Design: Acknowledge constraints and devise solutions based on user goals.
Usability: Ensure users can easily and effectively use the product.
Affordances and Signifiers: Objects should suggest their use (affordance) and provide visual cues (signifiers) to guide users.
Learnability: Design for easy learning and retention.
Empathy: Understand and share the user's thoughts and feelings.

UX Design

Focuses on the interaction between users and products/services.
Combines psychology, business, market research, design, and technology.
Aims to make products usable, enjoyable, and accessible.

Tasks and Processes of a UX Designer

User Research: Understand user needs and challenges.
Personas and Information Architecture: Define user types and structure content for easy navigation.
User Flows and Wireframes: Visualize user journeys and map out screen layouts.
Prototyping and User Testing: Test designs with users before development.
Visual Design: (Often handled by UI designers) Focuses on visual elements and aesthetic appeal.

Brainstorming Activity

Create personas to understand user behavior and goals.
Develop a POV (Point of View) statement for the persona.
Brainstorm ideas to improve user experience.
Create How Might We statements to generate solutions.
