What does ISO mean?
International Organization for Standardization
What are the six criteria for usability according to the ISO usability standard 9241?
Functionality
Reliability
Usability
Maintainability
Efficiency
Portability
___ is used to store information which is only required fleetingly
Short-term memory
What are the two types of LTM?
Episodic memory and Semantic memory
This is a structured record of facts, concepts, and skills that we have acquired, derived from the episodic memory
Semantic memory
It is the process by which we use the knowledge we have to draw conclusions
Reasoning
____ reasoning derives the logically necessary conclusion from the given premises
Deductive
____ reasoning is generalizing from cases we have seen to infer information about cases we have not seen
Inductive
____ reasons from a fact to the action or state that caused it
Abduction (Incomplete observation»_space; best prediction)
It is the process of finding the solution to an unfamiliar taste, using the knowledge that we have
Problem solving
The ___ theory states that problem solving is both productive and reproductive; insight is needed to solve problems
Gestalt (Optical illusion_
The _______ theory comprises problem states and problem solving involves generating these states using legal state transition operators
Problem Space Theory (i.e. Maslow’s Hierarchy of Needs)
Problems are solved by mapping knowledge relating to a similar known domain to the new problem
Use of analogy
The principles and properties discussed apply to the majority of people, but humans are not all the same
Individual differences
Give examples of text-entry devices
Alpha-numeric keyboard
Chord keyboard
Phone pad and T9 entry
Handwriting recognition
Speech recognition
Give examples of positioning devices
Mouse
Touchpad
Trackball and thumbwheel
Joystick and keyboard nipple
Touch sensitive screens
Stylus and light pen
Digitizing tablet
Eye gaze
Cursor keys and discrete positioning
In this type of storage, contents are lost when the power is turned offA
RAM
What is the basic standard for text storage?
ASCII and UNICODE
Describe the term in interaction being described:
Aid the user in accomplishing goals from some application domain
Purpose
Describe the term in interaction being described:
An area of expertise and knowledge in some real-world activity
Domain
Describe the term in interaction being described:
Operations to manipulate the concepts of a domain
Tasks
Describe the term in interaction being described:
Desired output from a performed task
Goal
Describe the term in interaction being described:
Specification required to meet the goal
Intention
Describe the term in interaction being described:
Identification of the problem space for the user of an interactive system in terms of domain, goals, intention and tasks
Task analyses
Describe the term in interaction being described:
Core language, describes computational attributes of the domain relevant to the system state
System’s language
Describe the term in interaction being described:
Task language, describes psychological attributes of the domain relevant to the user state
User’s language
Describe the term in interaction being described:
Computerized application
System
The user evaluates the results and determines 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
This refers to the study of physical characteristics of interaction
Ergonomics
What interaction style is being described:
It provides a mean of expressing instructions to the computer directly using function keys, single characters, abbreviations, or whole word commands
Command Line Interface
What interaction style is being described:
A set of menu options available for the user is displayed on the screen.
Menus
What interaction style is being described:
The ambiguity of natural language makes it very hard for a machine to understand
Natural Language
What interaction style is being described:
The user asked a series of questions and so is led through the interaction step by step
Question/Answer and Query Dialog
What interaction style is being described:
Primarily used for data entry but can also be useful in data retrieval applications
Form-fills and spreadsheets
What interaction style is being described:
This is the default interface style for the majority of computer systems today
WIMP (Windows, icons, menus, and pointers)
What interaction style is being described: This is closely related to the WIMP-style: pointing and clicking are the only action required to access information
Point-and-click interfaces
What interaction style is being described:
The simplest technique where ordinary WIMP elements are given a 3d appearance
Three dimensional interfaces (i.e. 3D VR)
What element of the WIMP-interface is being described:
Areas on the screen that behave as if they were independent terminals in their own right
Windows
What interaction style is being described: This is a small picture used to represent a closed window
Icon
What interaction style is being described: These are small bitmap images with a hotspot: the location to which they point
Pointers
What interaction style is being described: This represents a choice of operations or services that can be performed by the system at a given time.
Menus
What interaction style is being described: These are individual and isolated regions within display that can be selected by the user to invoke a specific action
Buttons
What interaction style is being described:
These are equivalent to menus, except that they can also hold buttons
Toolbars
What interaction style is being described: This is a mechanism for making the set of possible modes
Palettes
What interaction style is being described: These are information windows used by the system to bring the user’s attention to some important information
Dialog boxes
What are the most important senses in HCI?
Vision, hearing, and touch
True or false: It is no longer sufficient that users can use a system; they have to want to use it as well
True
