What is the significance of empathy in understanding the problem space and current requirements in design?
What is the significance of empathy in understanding the problem space and current requirements in design?
Empathy is crucial as it allows designers to truly understand and address users' needs and challenges, leading to more effective and user-centric solutions.
Explain the role of mood boards in the design process. What key aspects do they capture?
Explain the role of mood boards in the design process. What key aspects do they capture?
Mood boards serve to visualize the desired feel and aesthetic of a project, capturing elements like color palettes, textures, and imagery to guide the design.
Identify and explain two criteria for evaluating interface metaphors in terms of their effectiveness.
Identify and explain two criteria for evaluating interface metaphors in terms of their effectiveness.
Two criteria are relevance to the problem, ensuring the metaphor closely aligns with users' tasks, and extensibility, which assesses how well the metaphor can adapt to future changes or features.

Study Notes
Interfaces Design and Prototyping
- Prototypes are manifestations of a design, allowing stakeholders to interact with it.
- In other design fields, prototypes are small-scale models, such as miniature cars or buildings.
3D Printing Examples
- 3D printing creates models like jet engines, clothing (e.g., Spider Dress 2.0), and toys (teddy bears).
What is a Prototype in Interaction Design?
- A prototype in interaction design can include:
- Series of screen sketches
- Storyboards (cartoon-like scenes)
- PowerPoint slide shows
- Videos simulating a system's use
- Lumps of wood (mock-ups)
- Cardboard mock-ups
- Software with limited functionality in the target language or another language
Why Prototype?
- Evaluation and feedback are central to design.
- Stakeholders can easily interact with prototypes compared to documents or drawings.
- Team members can communicate effectively through prototypes.
- Prototypes allow for testing ideas.
- Prototyping encourages reflection, which is important in design.
- Prototypes support designers in choosing between alternatives.
Low-fidelity Prototyping
- Uses mediums different from the final product (e.g., paper, cardboard).
- Is quick, cheap, and easily changeable.
- Examples include:
- Sketches of screens and task sequences
- Post-it notes
- Storyboards
- Wizard-of-Oz
Storyboards
- A series of sketches illustrating how a user progresses through a task using the product.
- Often used with scenarios, providing detail and a chance for role-playing.
- Examples provided depict various stages of a user's interaction with a product (e.g., exploring Ancient Greece pottery markets).
Sketching
- Low-fidelity prototyping often relies on sketching.
- Don't be inhibited by drawing ability — practice simple symbols for representing elements.
- Examples of symbols include representations for people, digital devices, emotions and actions (happy, upset, surprise, sound, light).
'Wizard-of-Oz' Prototyping
- Users think they're interacting with a computer but a human responses (rather than an automated system).
- Usually done early in design to understand user expectations.
- Example question: What is "wrong" with this approach?
High-fidelity Prototyping
- Uses materials similar to the final product.
- Prototypes resemble the final system more than low-fidelity prototypes.
- Created by integrating existing hardware and software components.
- Risk that users might overestimate the system's completeness (be wary of compromises).
Conceptual Design
- A conceptual model outlines what users can do with a product and the necessary concepts for interaction.
- Focuses on understanding the problem space and current requirements, emphasizing empathy with users.
- Uses creativity and brainstorming techniques (e.g., mood boards).
- Considers different alternatives (e.g., scenarios) and prototyping to support the generation of creative ideas.
Choosing an Interface Metaphor
- Interface metaphors combine familiar knowledge with new knowledge to help users understand a product.
- The process involves three steps: understanding functionality, identifying potential problem areas, and generating metaphors.
- Evaluation involves considering structure, relevance to the problem, ease of representation, audience understanding, and extensibility.
Considering Interaction and Interface Types
- How do users invoke actions (e.g., instructing, conversing, manipulating, exploring, responding)?
- Do different interface types provide insights, such as shareable, tangible, and augmented reality interfaces?
Concrete Design
- This involves aspects like color, icons, buttons, interaction devices, user characteristics, and context.
- Key considerations include inclusiveness, input/output modes, accessibility (Web Content Accessibility Guidelines), cross-cultural design (language, colors, icons, architecture, and Indigenous knowledge), and perspectives.
