    Study Notes

    Chapter III: Understanding and Conceptualizing Interaction

    •  This chapter aims to explain the problem space, conceptualizing interaction, conceptual models, and the use of interface metaphors.
    •  It also outlines core interaction types, and introduces paradigms, visions, theories, models, and frameworks in interaction design.
    •  Conceptualizing design is crucial for a design project, involving idea generation by defining what a proposed product will do, sometimes referred to as a proof of concept.

    Objectives

    •  Explain the meaning of the problem space.
    •  Explain how to conceptualize interaction.
    •  Define a conceptual model and how to develop one.
    •  Discuss the role of interface metaphors in a conceptual model.
    •  Outline core interaction types to develop a conceptual model.
    •  Introduce interaction design paradigms, visions, theories, models, and frameworks.

    Proof of Concept (POC)

    •  A POC pertains to defining what the proposed product will do.
    •  For example, a POC for a voice assistant for smart homes could involve voice commands, basic commands (e.g., "turn on the lights," "play music"), and simple visualizations (e.g., animations, text feedback).

    Conceptualizing Design

    •  Examining ambiguous notions and presumptions about a product or service's merits is crucial in establishing feasibility.
    • Evaluating current tools, machinery, and technology to determine the practical development of the design.
    • The efficiency and desirability of a product are equally significant aspects to be assessed during the conceptualization process.

    Steps in Conceptualizing a Design

    •  Formulate all possible presumptions/assertions concerning the new design.
    •  Investigate the product's factual data, functionality, and limitations.
    •  Outline how users will overcome these limitations.

    Describing Complex Concepts

    •  Articulate, or provide detailed explanations of multifaceted notions.
    •  Illustrate the specifics of a design that may appear vague or unrealistic.
    •  Assess whether the design is achievable with current technology and equipment.
    •  Consider individual activities and interactions that might pose problems for the proposed design.
    •  Iteratively devise strategies to enhance and develop designs.

    Analyzing the Problem Space

    •  After identifying issues, the project proceeds to analyze the problematic areas.
    • A framework of questions can guide designers in analyzing problem spaces.

    Example Questions for Analysis

    •  Are there existing product or user experience complications? List them.
    • What causes this problem to exist?
    • How would you address the identified complications in your suggested design?
    • How appropriate your designed solution is in relation to existing practices, and is it beneficial or detrimental in its impact to the user experience?

    Conceptual Model Definition

    •  A model is a simplified portrayal of a system or process, illustrating how it functions.
    • In interaction design, conceptual models specifically articulate problem and design spaces.

    Key Components of a Conceptual Model (according to Johnson and Henderson)

    •  Metaphors and analogies that explain a product's application and function (e.g., a browsing metaphor for a web portal)
    •  Concepts that are presented through the product, allowing manipulation and actions (e.g., saving, organizing, revisiting)
    •  Interrelationships between the concepts (e.g., one object containing another)
    • Mappings between the concepts and the user experience (e.g., navigating to a saved page)

    Benefits of Conceptualizing

    •  Aligning design teams through a common understanding on perception of the design model.
    •  Encouraging a broad perspective during the early conceptualization stage to avoid narrow thinking.
    •  Fostering consensus among all members of the design team.

    Interaction Types

    •  Instruction, conversation, manipulation, and exploration are essential components of the user experience of a product or application.
    • Responding as an additional interaction component that initiates user interaction.

    Interface Styles

    •  Different approaches to interact with a product.
    • Examples include command-line interfaces, graphical user interfaces, menu-based interaction, and voice input.

    Paradigms

    •  A community of researchers and designers' general approach to their work, encompassing shared ideas, values, and practices.
    • Examples include the desktop paradigm and ubiquitous computing.

    Visions

    •  Future states that guide the design and development process, often presented figuratively (e.g., through narratives or movies).

    Theories

    • Well-founded descriptions of specific aspects or behaviors in a phenomenon (e.g., theory of information processing).

    Frameworks

    •  Sets of linked notions used to gain insight into a particular field or method (e.g., ethnographic studies).

    Interface Metaphors

    • Conceptualizing the actions of users, such as surfing the internet, instantiating conceptual models.
    • Examples include the desktop metaphor and shopping cart concepts.

    Benefits of Interface Metaphors

    • Simplification of learning new systems.
    • Enhancing understanding of underlying conceptual models.
    • Enabling computers and applications to cater to a variety of users.

    Problems with Interface Metaphors

    • Potential conflicts with existing conventions
    • Constraint on designer perspectives
    • Users might only grasp the system using the metaphor
    • Inadvertent adoption of poor features from existing designs.
    • Restriction of design imagination

    Examples of Core Interaction, Interface Metaphors and Conceptual Models

    •  Online shopping experiences (e.g., using a cart metaphor).
    • Everyday computer operations (e.g., desktop metaphor, web browsing).

    Conclusion

    • Conceptual models and interface metaphors provide the building blocks for creating user experiences.
    • The ability to analyze complex concepts is crucial in the design process.
    • Current designs may inherit poor aspects from existing designs, which can hinder the imaginative potential.
