FLEXIBILITY :

Multiplicity of ways in

which the users and

system exchange

information.

Dialog Initiative

-freedom from
system imposed
constraints on input
dialogue

For safety reasons, it may be
necessary to prohibit the user from
the “freedom” to do potentially
serious damages
- direct manipulation is user pre-
emptive
-system vs. user pre-emptiveness

Multithreading

-ability of system to
support user
interaction for more
than one task at a
time

-windowing system with an
audible bell. You are editing a
program when a beep indicates
that a new electronic mail message
has arrived.
- a windowing system support a
multi-threaded that is interleaved
amongst a number of overlapping
task. Each window can represent a
different task, for example text
editing in one window, file
management in another and
electronic mail in yet another
windows.
-concurrent vs. interleaving;

multimodality

Task

migratability

passing
responsibility for
task execution
between user and
system

-user can perfectly able to check
his spelling.
– this task also is perfectly suited
to automation.
– It is not desirable to leave this
task completely to computer...
-spell checking is best Performed

in such cooperative way.

Substitutivity

-allowing
equivalent values of
input and output to
be substituted for
each other

-Allow users to input margin for a
letter in inches or centimetres
-Representation multiplicity
illustrate flexibility for state
rendering
-representation multiplicity; equal

opportunity

Customizability

modifiability of the

user interface by

user (adaptability)

or system

(adaptivity)

-users ability to adjust the form of
input and output
- automatic customization of the
user interface by the system

3 Observability -ability of user to
evaluate the

brows ability; defaults;
