Flashcards

Cognition

The mental processes involved in acquiring, storing, and using knowledge. It encompasses how we perceive, think, learn, and solve problems.

Mental Models

Mental models are internal representations of how users understand a system's workings. They guide users' interactions by providing expectations and interpretations.

Attention

The ability to focus on specific information while ignoring distractions. It's crucial for interface design because it determines how effectively users can process information presented.

Perception

The process of interpreting sensory information from the world. It's involved in how users perceive and understand the layout, colors, and visual elements of an interface.

Memory

The encoding, storing, and retrieving of information over time. It's fundamental to interface design because it impacts how users learn, remember, and navigate complex systems.

The 7-item rule

A rule stating that interface elements like menu options, toolbars, and lists should not exceed 7 items.

Signup and view all the flashcards

How does the 7-item rule relate to user memory?

Users are able to scan lists, tabs, and menus for the desired item, making recall from memory unnecessary.

Is the 7-item rule always applicable?

The rule is not absolute; it depends on factors such as task complexity and screen size.

Study Notes

Interface Design - ITD34003

  • Course content focuses on understanding users, how interfaces affect users, and a user-centered approach.
  • Key discussion topics include cognition, its importance in HCI, applications of cognition in interaction design, and the concept of mental models.
  • Different thinking styles, like fast vs. slow thinking, are crucial to interface design.
  • Understanding cognition assists in anticipating user problems and challenges for improved interactive product design.
  • Cognitive processes include attention, perception, memory, learning (reading, speaking, and listening), and problem-solving, planning, reasoning, and decision-making.
  • Interface design should use techniques to make salient information important, avoid information clutter, and support effective transitions and returns.
  • Examples of this include using color, ordering, spacing, underlining, and animation to guide the user's attention.
  • Good interface design recognizes differences in how people perceive and process information (e.g., visual clarity, readability).
  • Memory is critical, including recalling information, encoding and retrieving knowledge, and recognizing versus recalling.
  • The classic 7+/-2 theory in memory capacity has implications in interaction design.
  • Multitasking can impair attention and cause errors; use of phones while driving is dangerous and should be avoided.
  • Website design focuses on accessible and easy-to-use information.
  • Methods to organize and track information (such as folders, categories, labels, highlighting, time stamping) are important for memory and effective management.
  • Techniques like breadcrumbs can enhance navigation on websites.
  • Mobile interfaces, such as smartphones, tablets, and smartwatches, are pervasive and require design considerations.
  • Interface design considerations for different types of users, like those with visual impairments, are essential.
  • Voice user interfaces (VUI) allow users to interact with interfaces using spoken language.
  • Interface design for VUI needs clear speech, and proper emphasis on intonation.
  • People solve problems, plan, and make decisions involving reflective cognition.
  • Effective interaction design considers factors influencing users' cognition throughout the process.
  • Interfaces need clear prompts, tutorials, and help pages supporting successful interaction.
  • Concepts like the "gulf of execution" and "gulf of evaluation" show the distance between the user and the system. Bridging these gulfs helps reduce cognitive load and simplifies interaction.
  • Information processing is a crucial aspect of interface design with emphasis on stages: input, encoding, comparison, response selection, response execution, and output.
  • External cognition involves how external representations like diagrams, maps, and notes influence our mental processes.
  • Interface design can use techniques like annotation (underlining, highlighting) and cognitive tracing (ordering ideas) to reduce cognitive load.
  • Mental models (understanding how systems work) help users predict and interpret their actions and responses.
  • Examples of mental models are provided in the everyday reasoning scenarios.
  • Interfaces should be designed to make it easier for people to learn.
  • New technologies, like virtual reality, need interfaces supporting exploration, interaction, and engagement.
  • Important considerations in visual interface design are clear categorisation, use of various visual cues, and design for different display sizes.
  • Interfaces should allow for simple navigation of multiple types of device.
