Study Notes
Introduction to Human-Computer Interaction (HCI)
- HCI is the conscious and intuitive effort to impose meaningful order on products.
- Understanding users' motivations, desires, and contexts is crucial.
- Effective design considers business, technical, and domain opportunities, constraints, and consequences.
- Poor design results in products that are rude, require users to think like computers, have sloppy habits, and require excessive human effort.
Why Digital Products Fail
- Misplaced priorities by product/development teams
- Insufficient understanding of baseline user needs.
- Conflicts of interest in development teams.
- Lack of design processes to gather, analyze, and use user knowledge.
Goal-Directed Design
- Companies often focus on user tasks but not their goals.
- Goals represent end conditions; activities/tasks are intermediate steps.
- Activity-centered design (ACD) focuses solely on activities, potentially ignoring user goals.
- A good design integrates an activity-centric and goal-directed approach.
Implementation, Represented, and Mental Models
- Implementation model: how the software actually works.
- Mental model: user's perception of how the application works.
- Represented model: how designers represent the application workings to the user.
Design Principle: User Interfaces & Mental Models
- User interfaces should be based on user's mental models not implementation models.
- Goal-directed interactions reflect user models, needing a translation from user research to detailed specifications.
Goal-Directed Design Research
- Ethographic/qualitative methods to understand potential users and their usage.
- Identify and categorize user behaviors through observations.
Goal-Directed Design Modeling
- Synthesize behaviors and work flow patterns in domain and user models.
- Create Requirements for the product based on the user/domain models.
- Define design structure through framework definition.
- Refine behaviors, form, and content to ensure a consistent and usable product..
User-Centered Design (UCD)
- Focuses on the users' needs throughout the design process.
- Stakeholders are individuals involved in the development/deployment.
- Primary: direct users, Secondary: receive output/input,Tertiary= indirect involvement. Facilitating support, resources, etc.
Input-Output Mission
- Humans interact with computers via sensory and motor systems (5 senses, hands, head, etc).
- Computer systems perform sequences of arithmetic or logical operations automatically (CPU, RAM, etc).
- Computer systems are typically understood as Hardware + Software + Peripherals.
Accessibility
- A product's accessibility refers to how many people can use the technology.
- Disabilities can be viewed as a result of poor interaction design; not the impairment itself.
Types of Impairment
- Sensory, Physical, Cognitive, Permanent, and Temporary/Situational
User-Centred Design (UCD) and Need-finding
- Design requires recognizing user needs.
- Technology is less important than the user's needs (the design of ACD).
- Test the design for success and failure.
- Design with stakeholders to ensure user needs are met.
- Focus on user experience (saftey, simplicty, affordibility, and meaningfulness).
Goal-Directed Design Principles
- User experience focuses on problems, not the creator/designer.
- Understanding users' problems and needs is a central part of the design process.
- The design should be based on factual information/user needs.
- Avoid guesswork, creative whims of the designer, or personal preferences.
Different Phases of Goal Directed Design
- Research: Understand users, domain.
- Modeling: Develop user, and domain models.
- Requirements definition: Connection between users/models and design framework..
- Framework definition: Product concept, behavior, design.
- Refinement: Documentation of design (formal specifications or blueprints).
User Observations
- Naturalistic: Observing user behavior in their natural environment.
- Controlled: Observing user behavior in a controlled environment, for quantifiable data.
Design Alternatives (Ideation)
- Requirements evolve during stakeholder interaction.
- Design should facilitate everyday communication.
- Personas, and scenarios are vital.
- Include detailed descriptions of user behavior, activities, and environments.
Prototyping
- Low-fidelity: Inexpensive, quick iterations/revisions.
- High-fidelity: Realistic; resembles the final product.
- Medium-fidelity: Balance between low & high fidelity prototypes.
Principles, Heuristics, and Feedback
- Heuristic evaluation: Identify design problems using guidelines/heuristics.
- Usability Testing: Evaluating through user interaction.
- Formative or Summative testing.
Human-Robot Interaction (HRI)
- HRI focuses on human-robot interaction/social interaction with robots.
- Human-robot social interactions can involve spatial, non-verbal, and verbal interactions.
Cognitive Processes in HCI
- Fast thinking: intuitive, effortless; Slow thinking: logical, demanding.
- Attention: focusing on relevant information.
- Perception: transforming environmental information into experience.
- Memory: recalling and retaining information.
Intelligence in User Interfaces (IUIs)
- Intelligence is challenging to define concretely.
- IUIs adapt to user needs, anticipate needs, and learn user behavior.
