Chapter 2 Flashcards
It refers to a particular approach that has been adopted by the community in terms
shared assumptions, concepts, values and practices
Paradigm
allows the user to achieve particular goals in some
application domain (usable).
Objectives of an interactive system
means one computer could support multiple users
Timesharing
The earliest applications of this were developed for military purposes
Video Display Unit
When Sketchpad was developed?
1962
demonstrated, computer could
be used to create visual models.
Sketchpad
idea of building components of computer that will
allow you to rebuild a more complex system
Bootstrapping
small components can be used to create
larger tools. Larger tools can create more complex systems
Bootstrapping
Example of first computing application
NLS (On-line System)`
True or false: As the modern era arises, it is more difficult to
distinguish between personal computer from
workstation
True
As the modern era arises, it is more difficult to
distinguish between personal computer from
workstation
Personal Computing
True or False: The personal computer needs to be flexible to be an effective dialog partner
True
With the use of this, computers can message the user in the context of their task.
Microsoft Windows
The personal computer needs to be flexible to be an effective dialog partner. With the
use of Microsoft Windows, computers can message the user in the context of their task.
Windows System and WIMP interface
used to teach new concepts with the terms which are already
understood. It portrays a cultural bias so it is difficult for this to be internationally
understood.
Metaphor
What is not a feature of a Direct Manipulations?
A. Visibility of the objects of interest
B. Incremental action at the interface with rapid feedback on all actions.
C. Reversibility of all actions, so that users are discourage exploring without severe
penalties.
D. Reversibility of all actions, so that users are encourage exploring without severe
penalties.
F. Syntactic correctness of all actions, so that every user action is a legal operations
G. Replacement of complex command languages with actions to manipulate
directly the visible objects.
seen as the mediator between the user and the system.
Interface
True or false: The user gives
instructions to the interface while responsibility of the interface is to see that those instructions are
carried out.
True
Are both statements are true?
Users need to understand how the underlying system function and the interface as
interlocutor (mediator) need not to perform much translation.
User doesn’t need to understand the underlying system: the interface serves a more
active role by translating and interpreting the user’s input to correct system commands
Both statements are true
a storage and retrieval apparatus that is used to link different text together.
This also points to the irregular structure of information
Hypertext
systems that are built to allow interaction between humans using the computer
and so the needs of the users must be represented in the one product.
Computer Supported Cooperative Work
the graphic top-layer which is popular for exchanging information in the HTML mark -up
notation
World Wide Web
perform action for the user, but the number one problem is to specify the user’s
tasks correctly in clear language. Some agents use AI to specify the user’s task correctly and
understandably.
Software agents
The goal of this is to create a computing infrastructure that fills our physical environments so
much that we do not notice the computer any longer
Ubiquitous Computing
It is simply the future idea of the computer adjusting to our own behaviours and performing on
background using the information gathered from the sensors
Sensor-based and context-aware interaction
True or False: Be right as often as possible when acting on these correct predictions.
True
True or False: Do not cause unreasonable problems in the event of an action resulting from a wrong
prediction.
True
