Designing for People

  • Good interfaces start with understanding people.

    • Four-part structure to understand users:

    • Context (Who are they?)

    • Goals (What do they want to achieve?)

    • Research (Understand goals and context)

    • Patterns (Cognition and behavior related to interface design)

Interaction

  • Interaction involves 2 or more entities engaging, influencing, or communicating with each other.

    • Includes exchange of information or actions leading to mutual outcomes.

    • Types of interaction:

    • Touch-based

    • Mouse & keyboard

    • Voice

    • Gesture-based

    • Stylus or pen

    • Motion-based

    • Haptic feedback

    • Brain-computer interfaces

Design Process

  • Process involves creating and planning to solve problems or meet user needs.

  • Human-Computer Interaction (HCI) perspective: planning interactions to ensure effectiveness, enjoyment, and efficiency.

  • Interaction Design (IxD): structuring how users interact with products, systems, or services.

    • Focus on ensuring a good user experience.

Context

  • Understanding your audience is critical; designers are not always users.

  • Interaction as conversation:

    • Involves a constant exchange of information.

  • Designers must provide feedback similar to conversation partners (vocabulary, icons, gestures).

  • Match interaction style and functionality with user knowledge levels.

Goals

  • Goals are outcomes users want to achieve through interaction.

    • Goals include:

    • Finding a face or object

    • Learning

    • Transactions

    • Monitoring/control

    • Creating

    • Conversing

    • Entertainment

  • Design must account for users' goals for effective user-centered design.

Research

  • Research is critical for insights into user needs.

    • Empirical discovery is crucial, using qualitative (interviews) and quantitative (surveys) methods.

  • User discovery involves observing and understanding user tasks and their language.

Patterns

  • Patterns are established behaviors and cognitive habits related to software interfaces.

    • Successful interfaces support these patterns.

  • Encourage safe exploration: allow users to try and fail without significant consequences.

  • Instant gratification: quick results retain user engagement.

  • Satisficing: provide straightforward options to avoid overwhelming users.

Changes in Midstream

  • Allow users to change tasks mid-process without losing previous actions.

  • Design for deferred choices and incremental construction based on user needs.

    • Support users’ memory and tool usability.

Social Media and Collaboration

  • Acknowledge the influence of social interactions and peer opinions on user behavior.

    • User-generated content enhances credibility and motivation.

Relationship Among UI, UX, and IxD

  • UI: What happens on the screen (visual elements)

  • UX: Overall user satisfaction in using a product

  • IxD: User-system interactions (navigation, animations)

    • A well-designed product harmonizes all three aspects.

Importance of Interaction Design

  • Interaction Design ensures users can efficiently accomplish goals, enhances satisfaction, and leads to better conversion.

Design Process Overview

  • Requirements: Analyze what exists versus what is needed.

  • Analysis, design, interaction prototyping, implementation, and deployment.

Why Products Fail

  • Failures often arise from misplaced priorities, ignorance of user needs, and lack of a structured design process.

UX Design Framework Components

  • Strategy: Define purpose and user needs.

  • Scope: Determine features and functionality.

  • Structure: Create logical flow for interactions.

  • Skeleton: Develop wireframes and interaction patterns for usability.

  • Surface: Apply branding and visual design elements.

Design Thinking Framework

  1. Discovery: Gather data on topics.

  2. Reframe: Identify patterns and insights.

  3. Incubate: Allow ideas to develop.

  4. Ideate: Generate solutions and explore possibilities.

  5. Evaluate: Assess desirability and feasibility of ideas.

  6. Prototype/Test: Rapid prototyping for feedback.

  7. Deliver: Final testing and launch.

  8. Iterate/Scale: Continuous evaluation and improvement.

Context in Interaction Design

  • Consider physical, social, technological, task, and user contexts in design.

  • Context ensures usability and enhances user satisfaction.

Information Architecture

  • Organizing, structuring, and labeling content effectively to support navigation and usability.

    • Data organization, label consistency, navigation systems, and search tools are crucial.

Importance of Information Architecture

  • Supports user goals, enhances accessibility, improves findability, and boosts user engagement.

User Flow Mapping

  • Visual representation of user steps to complete tasks, identifies pain points for optimization.
