Abowd and Beale's Interaction Framework

Abowd and Beale's interaction framework expands upon Norman's model, adding the crucial concept of translation between different languages used by the user, input, system, and output.

Interaction Problems

Interaction problems arise from difficulties in translating between the distinct languages used by the user, input, system, and output.

Understanding Interaction

The framework describes how user intentions are converted into actions at the interface, modifying the system's state and reflected in the output display.

Generality of Framework

The framework applies broadly, not just to computer systems, revealing the core components involved in any interaction.

Study Notes

Interaction Framework

  • Abowd and Beale's framework extends Norman's interaction framework, consisting of 4 parts: user, input, system, and output.
  • Each part has its own unique language, and interaction is a translation between these languages.
  • Problems in interaction arise from problems in translation.

Understanding Interaction

  • Abowd and Beale's model describes how user intentions are translated into actions at the interface, altering system state, and reflected in the output display.
  • The framework is general and not restricted to electronic computer systems, identifying all major components involved in interaction.
  • It allows for comparative assessment of systems and is an abstraction.

Ergonomics

  • Ergonomics studies the physical characteristics of interaction, also known as human factors.
  • It is good at defining standards and guidelines for constraining the way we design certain aspects of systems.
  • Examples of ergonomics include:
    • Arrangement of controls and displays (e.g., grouping by function or frequency of use)
    • Surrounding environment (e.g., seating arrangements adaptable to user size)
    • Health issues (e.g., physical position, environmental conditions, lighting, and noise)
    • Use of color (e.g., red for warning, green for okay, and awareness of color-blindness)

Initiative

  • Initiative refers to who has the initiative in the interaction: the user or the computer.
  • WIMP interfaces have shifted the initiative from the computer to the user.
  • Exceptions include pre-emptive parts of the interface, such as modal dialog boxes.

Error and Repair

  • Errors can't always be avoided, but we can make it easy to detect and repair them.
  • Example: error correction in a booking system, where the user is prompted to confirm their selection.

Context

  • Interaction is affected by social and organizational context, including:
    • Other people (e.g., desire to impress, competition, fear of failure)
    • Motivation (e.g., fear, allegiance, ambition, self-satisfaction)
    • Inadequate systems (e.g., causing frustration and lack of motivation)

Experience, Engagement, and Fun

  • Designing experience involves creating physical engagement and managing value.
  • Experience is not just about usability, but also about creating an enjoyable experience.
  • Psychology of experience includes concepts like flow (Csikszentimihalyi) and balance between anxiety and boredom.

Designing Experience

  • Real-world examples: designing experiences for home, entertainment, and shopping.
  • Psychology of experience: flow (Csikszentimihalyi) and balance between anxiety and boredom.
  • Education: zone of proximal development and things you can do with help.
  • Menu design issues: which kind to use, what to include, words to use (action or description), and how to group items.
  • Types of menus: cascading menus, keyboard accelerators, and menus extras.

Buttons

  • Buttons are individual and isolated regions within a display that can be selected to invoke an action.
  • Special kinds of buttons include radio buttons and check boxes.

Toolbars

  • Toolbars are long lines of icons providing fast access to common actions.
  • Often customizable, allowing users to choose which toolbars to see and what options are on them.

Palettes and Tear-Off Menus

  • Palettes are little windows of actions that can be shown or hidden via menu option.
  • Tear-off menus 'tear off' to become palettes, solving the problem of menus not being available when needed.

Dialogue Boxes

  • Dialogue boxes are information windows that pop up to inform of an important event or request information.
  • Examples: saving a file, where a dialogue box appears to specify filename and location.

Look and Feel

  • WIMP systems have the same elements: windows, icons, menus, pointers, buttons, etc.
  • Interactivity is important, but often overlooked in favor of focusing on look.
  • Speech-driven interfaces are rapidly improving but still require robust dialogue.
