an acronym for windows, icon, mouse, and
pointer which represents the conventional desktop
interface
- WIMP
- the implementation will typically consist of widgets
view
While supporting a quick completion of the task is
important, error free operation is equally important.
Prevent Errors / Reversal of Action.
interactive systems designers need to
know about includes software, hardware,
communications, and content
Technologies
also leads to less erroneous
behavior this pack is well applied to interface design for
instance in keeping the number of menu items or depth
to less than this amount to maintain good user
awareness of the ongoing tasks or in providing reminders
and status information continuously throughout the
interaction
light memory burden
need a variety of skills and need to
understand a variety of disciplines
UX Designers
futurologist to some extent the better
essence of their job is to create the future or at least
some pictures of it
Designer
- information systems methods have developed over the
years to ensure that information systems are effective
and meet the needs of people who work there
Activities and Contexts
the interaction and interface should be
designed to avoid confusion and mental overload.
Prevent Errors / Reversal of Action.
The final major HCI principle is to favor “natural”
interaction and interfaces.
Naturalness.
- the region or portion of the screen or display that is no
longer consistent with the model is said to be damaged
view
- In the longer term, one way to unburden the memory
load is to keep consistency.
Strive for Consistency.
- does practically takes care of the input part of the
interaction
Controller
a design pattern used to decouple user interface
as view data, as model, and application logic as controller
MVC
- interactive applications are implemented and executed
using the user interface or UI software layers or
collectively the UI layer
Design
to maintain the user’s awareness of the situation and
further illicit correct responses informative momentary
or continuous feedback will repress the user’s memory
and help the user complete the task easily
Remind Users and Refresh their Memory.
the core computational and interface parts are
developed in a modularized fashion and combined in a
flexible manner such a development framework
Model, View, and Controller or MVC Architecture
about five to nine chunks of information or items
meaningful with respect to the tests painlessly known as
the magic number
human’s short-term memory or STM
Designing interaction with as little memory load as
possible is a principle that also has a theoretical basis.
Reduce Memory Load.
first problem we must confront
Design
- The more effective the use of imagery at the interface,
the more engaging and enjoyable it can be
(Mullet and
Sano. 1995)
corresponds to the computation
Model
HCI Guidelines Criteria
- User Type
- Platform/System Setup
- Vendors/Organizations
- Interface Style/Modality/Technology
- Task/Operational Context
- Applications
- General HCI Design
This principle simply states that the interaction and
interface should cater to the needs and capabilities of the
target user of the system in design
“Know Thy User”.
it is simply a process to reinforce the original
requirements analysis to further accommodate the
potential users in a more complete way
User Analysis
refers to a trait that is reflective of various
operations in our everyday life.
Naturalness.
A well-known approach to designing affective
interfaces is to use expressive icons and other graphical
elements to convey emotional states
Expressive Interfaces
- Used for Interactive Applications
