Study Notes

Conceptualizing Interaction Design

Conceptualization clarifies vague ideas and assumptions regarding a product's benefits and feasibility.
Design assumptions guide decisions, based on hypotheses about user needs but must be validated with evidence.
Distinguish between assumptions (user needs) and claims (statements open to question) in design discussions.

Importance of Assumptions and Claims

Writing down assumptions helps identify unrealistic thoughts and potential risks in design.
Activity prompts students to explore how robot servers interacting with customers could improve experiences; requiring identification of benefits and risks.
Recognize problems that current products present and design to address or improve these issues.

Framework for Problem Analysis

Understanding existing issues allows for better design solutions.
Questions like sources of inspiration, existing problems, and how new designs could improve user experience are critical in the early design stages.

Interface Metaphors

Designed to resemble physical entities but possess unique properties, making the unfamiliar more understandable.
Examples include desktop metaphors and visual representations like shopping carts.
Benefits include easier learning curves and increased accessibility for diverse users, though they risk constraining design thinking and may impose cultural misunderstandings.

Interaction Types

Instructing: Users issue commands to the system (e.g., printing documents).
Conversing: Engaging with the system through dialogue.
Manipulating: Interacting physically with objects.
Exploring: Navigating virtual or physical environments.
Responding: Users react to system-initiated prompts.

Choosing Interaction Types

Direct manipulation suits hands-on tasks; issuing instructions benefits repetitive tasks; conversational interfaces are ideal for informational queries.
Different tasks may require hybrid models to support multiple ways of performing actions.

Differentiating Interaction Types and Interface Styles

Interaction types describe user activities while interface styles define the manner in which these interactions are facilitated (e.g., command, graphical, voice).

Summary of Conceptual Model Development

Involves understanding the problem space, clarifying assumptions and claims, and defining how designs support user actions.
A conceptual model encapsulates user capabilities and required understanding.
Interaction types facilitate user activity support, enhanced by paradigms and frameworks that guide design and research.
