Topic 2 Flashcards
Scientific study of how people interact effectively with products, equipment, facilities, procedures, and environments used at work and in everyday living.

Three Parts of HCI
Human
Computer
Interaction
Could be any technology ranging from the general desktop computer to a large-scale computer system.
Computer
any direct or indirect communication between a human and computer.
Interaction
could be an individual user or a group of users.
Human
The original interfaces for the computer and are still used.
Command line interfaces
A basis of WIMP interfaces and a favorite with inexperienced users. Novice users can easily find commands. Searching the ___, the user builds up a metaphor for the application.
Menus
___ or “question and answer” boxes are another old interface style. They are windows that pop up asking for information, fields to be filled or buttons to be pressed.
Dialogs
___ are sophisticated dialog boxes and not much more
flexible.
Forms
___ are a flexible and powerful form of interface, especially if the user can specify cell types.
Spreadsheets
___ and ___ interfaces were made popular by the web. They were very suitable for the initial web browsers (gopher) when web pages were all text. Users knew to interpret the underscore as a link to another web page.
Point and click
___ interface style selects an object and uses a gesture to issue commands. In essences, it is a generalization of “point and click” interfaces.
Command gesturing
___ is a more general interface style than command gesturing. There does not have to be an object and the gesture does not have to represent a command.
General gesturing
___ is drag and drop files into
folders or trash.
Direct manipulation
___ refer to manipulating physical objects other than the mouse and keyboard.
Tangible interactions
Preece, Rogers and Sharp in Interaction Design propose
that understanding users’ conceptual models for interaction can guide HCI designers to the proper interaction techniques for their system.
Conceptual Interaction Models
issuing commands to the system
Instructing
user ask the system questions
Conversing
users interact with virtual objects or environment
Manipulating and Navigation
system provides structured
information
Exploring and Browser
_ are
probably the most common form of conceptual interactions. It allows the user the most control
over the system.
Instructional Interactions
___ model the interaction as a user-system dialog. Agents (such as the paper clip) use
this. Implementing ___ may
require voice recognition and text parsing or could use forms.
Conversational Interactions
This model describes the interaction of manipulating
virtual objects or navigating virtual worlds. These interactions are popular in computer
games.
Manipulating and Navigational Interactions
___ refer to searching structured information. Examples of systems
using explorative interactions are Music CDs, Movie DVDs, Web, portals.
Explorative and Browsing Interactions
