From Interaction Flashcards
Models of interaction:
Aid the user in accomplishing goals from some application domain.
Purpose of an interactive system
Models of interaction:
An area of expertise and knowledge in some real-world activity
Domain
Models of interaction:
Operations to manipulate the concepts of a domain
Tasks
Models of interaction:
Desired output from a performed tasks.
Goal
Models of interaction:
Specification required to meet the goal.
Intention
Models of interaction:
Identification of the problem space for the user of an interactive system in terms of domain, goals, intention and tasks.
Task Analyses
Models of interaction:
Core language, describes computational attributes of the domain relevant to the system state.
System’s Language
Models of interaction:
Task language, describes psychological attributes of the domain relevant to the user state.
User’s Language
Models of interaction:
Computerized application
System
The plan formulated by the user is executed by the computer. When finished, the user evaluates the results and determines the further actions.
The execution-evaluation cycle
On the user-side, communication is in task-language and on the system side, in core language.
The interaction framework
The study of the physical characteristics of the interaction. ____________ contribution to HCI is in determining constraints on the way we design systems and suggesting detailed and specification guidelines and standards.
Ergonomics
Interaction styles:
It provides a mean of expressing instructions to the computer directly using function keys, single characters, abbreviations or whole word commands
Command Line Interface or CLI
Interaction styles:
A set of menu options available for the user is displayed on the screen.
The _______ can be presented text-based and graphical
Menus
Interaction styles:
The ambiguity of natural language makes it very hard for a machine to understand.
Natural Language
Interaction styles:
The user asked a series of questions and so is led through the interaction step by step.
Question/Answer and query dialog
Interaction styles:
Primarily used for data entry but can also be useful in data retrieval applications.
Form-fills and spread sheets
Interaction styles:
Windows, icons, menus and pointers: the default interface style for the majority of computer systems today.
The WIMP interface
Interaction styles:
The PCI is closely related to the WIMP-style: pointing and clicking are the only action required to access information
Point-and-click interfaces
Interaction styles:
The simplest technique is where ordinary WIMP elements are given a 3D appearance. A more complex technique uses interfaces with 3D workspace. The most complex 3D workspace is virtual reality (VR).
Three-dimensional interfaces
Elements of the WIMP:
Interface_______ are areas on the screen that behave as if they were independent terminals in their own right.
Windows
Elements of the WIMP:
An ______ is a small picture used to represent a closed window.
Icon
Elements of the WIMP:
__________ are nothing more that small bitmap images with a hotspot: the location to which they point
Pointer
Elements of the WIMP:
A _______ represents a choice of operations or services that can be performed by the system at a given time.
Menu(s)
Elements of the WIMP:
________ are individual and isolated regions within display that can be selected by the user to invoke a specific action.
Buttons
Elements of the WIMP:
Mostly equivalent to menus, except for that a _______ can also hold buttons.
Toolbar
Elements of the WIMP:
________ are mechanism for making the set of possible modes and the active
Palettes
Elements of the WIMP:
_________ are information windows used by the system to bring the user’s attention to some important information.
Dialog boxes
It is a multidisciplinary field of study focusing on the design of computer technology and, in particular, the interaction between humans (the users) and computers.
Human-Computer Interaction (HCI)
_________ is the data output by the computer vice versa. Vision, hearing, and touch are the most important senses in HCI.
Human input
