Study Notes
Human Computer Interaction
- Human-Computer Interaction (HCI) is a design subject, well-studied with rich traditions
- Designers use methodologies to create better interfaces
- HCI is viewed as a design problem concerning the user experience, encompassing design considerations for usability, efficiency, safety and satisfying user goals
Interface Design
- Interface principles include:
- Interesting, pleasing, attractive, and inviting; effective to use
- Intuitive
- Earning user trust
- Clean, organized, hierarchical structure
- Help functions, search capabilities
- Consistent forms with design integrity
- Automatic assistance (auto-completion, spell-checking)
- Leading users (prompts, nature of problem, specific communication)
- Navigational aids for large systems
- Meaningful error messages (not sending user elsewhere, giving useful numbers)
- Multiple paths to a function
- Keeping the interface simple
Learning Goals for HCI
- Overview of the interaction design process
- Understanding of what "design" means
- Understanding user involvement in the design process
- Understanding the User-Centered Design (UCD) Process
What is Design?
- More than just problem-solving
- Includes multiple points of view
- Requires vision, multiple minds, openness, and learning from experience
- A combination of reflection, feel for materials, broadening ideas, and subsequent narrowing
- Ongoing mindfulness is necessary
Need to Take into Account
- Understanding user needs, activities, and interaction settings
- Optimize user interaction with product to match activities and needs
- Consider user skills and strengths/weaknesses
- Consider how people currently go about tasks, to enhance
- Aim for quality user experiences
- Use tried-and-tested user-centered methods
Goals of Interaction Design
- Developing usable products (easy to learn, effective use, enjoyable experiences)
- Involving users in the design process
Usability Goals
- Effective to use
- Efficient to use
- Safe to use
- Have good utility
- Easy to learn
- Easy to remember how to use
Why Go to This Length?
- Help designers understand how to create interactive products that meet users' needs and desires
- Identify and correct mistaken assumptions about particular user groups
- Recognizing user sensitivities and capabilities
User Experience Goals
- Satisfying
- Enjoyable
- Engaging
- Pleasurable
- Exciting
- Entertaining
- Helpful
- Motivating
- Emotionally fulfilling
- Challenging
- Supportive of creativity
- Enhancing sociability
- Rewarding
- Fun
- Surprising
- Provocative
- Boring
- Annoying
- Frustrating
Good & Bad Design
- Example comparison of an Apex remote and a TiVo remote (discusses design flaws that hinder usability)
Interaction Design Process
-
Design is inherently creative and unpredictable, regardless of the discipline
-
Combines technical understanding with aesthetic elements to create interfaces that satisfy users.
-
Design is a process, not a state, that can not be represented statically
-
The design process is non-hierarchical, not strictly top-down or bottom-up.
-
Design is transformational; it involves partial and interim solutions that may not be in the final product
-
Design inherently involves the discovery of new goals
-
Key Stages in the Interaction Design process include:
- Identifying needs
- Developing alternative designs
- Building interactive prototypes (that are communicated and assessed)
- Evaluating the process and the user's experience it offers
Core Characteristics of Interaction Design
- Users should be involved throughout the project
- Specific usability and user experience goals should be established at project start
- Iteration is important throughout the process.
Design Phases
- Understand
- Observe
- Visualize and Predict
- Evaluate and Refine
- Implement
Analyzing Needs
- Needs drive and dictate design
- Iterative design process is essential
Contextual Inquiry
- Users and stakeholders
- Context of the interviewee's workplace
- Designer apprenticing to interviewee
- Guided by interviewee
Contextual Interviews
- Interpretation and elicitation of needs within the context and by the interviewee
- Short, focused on behaviours
- Aim to design a new system
Capturing Data
- Observer's notes
- Written notes
- Sketches and photographs
- Audio or video recordings
Generating an Idea
- Brainstorming - a crucial step for creativity
Brainstorming Rules
- Be visual
- Defer judgment
- Encourage wild ideas
- Build on ideas of other participants
- Go for quantity, not quality
- One conversation at a time
- Stay focused on the topic
Explore Design Ideas
- Needs, design, evaluate, implement as iterative
Sketches
- Illustrative examples
Flow Diagrams
- Graphic representation of process steps
Prototyping
- Iterative process, critical for envisioning together different perspectives from various parties
- Focus for identifying alternatives during reflective conversation on materials and trade-offs
Low-Fidelity Paper Prototype
- Tools include paper, cardboard, transparencies, tape, glue, rubber cement, pens, pencils, markers, scissors, plastic tubes, paper cups, and CDs
- Low-fidelity prototypes are examples in the form of sketches, diagrams or on paper
Tools for Prototyping
- HTML and Javascript
- Java Swing
- Visual C#, Visual Basic
- Flash MX, Director
- Mac Interface Builder
- A mix of the above
Methods for Getting Users Involved
- Users and stakeholders throughout the entire design process
User-Centered Design
- Users drive the force behind development
- Users are consulted throughout development
- Decisions are made within the context of user work, and environment
Stages of User Involvement
- Need finding
- Design (participatory design)
- Implementation (end-user programming)
- Evaluation
- Use in the target setting
- Users can be involved in any stage
Why is Design Difficult?
- Increasing complexity/pressure
- Marketplace pressures
- Consideration for cost and appearance surpassing human factors design
- Challenges in creativity
Idea Creation
- Methods of idea generation
- Drawing on other fields
- Analogies
- Concepts of magnification and adaptation
- Generating creative ideas with approaches like consideration of object use, adapting objects, modification, or combinations, etc.
Design Principles
- Use simple and natural dialog in user's language
- Match user's task with a natural method
- Avoid slang and techno-speak
- Present exactly the needed information
- Strive for consistency with sequences, actions, commands, layout, and terminology
- Providing informative feedback about occurring actions and delays
- Minimize user's memory load (recognition vs. recall, example formats with defaults)
- Permit easy reversal of actions
- Provide clearly marked exits
- Provide shortcuts for often-used operations
- Support internal locus of control
- Handle errors gracefully
- Provide useful help and documentation
