Structure

20


Splash screen is usually with little
information and of no use.

21


Do not use abbreviations. People will not
understand your app.

Do not use brackets for commands. Text
becomes hard to read.

23


Bold typeface is not good enough as an
indicator.

24


Describe all features and all possible values
in the Help section.

25


Dialogs should not be cryptic but crystal
clear.

26


Do not use LCDUI Dialog for Help or About.
Use the TextBox instead.

27


Do not set a highlight or an indicator to any
field which people cannot effect.

28


LCDUI’s multiple ChoiceGroup does not
work as switch metaphor in Nokia Asha.

29


It is too easy to (re-)place a number by
accident.

30


Check state requires an “uncheck” state,
since you toggle a state not a view.

31


Quicksavekeys do not work as there are no
hardware keys. Save in background.

32


HW Back key must exit the game from the
topmost hierarchy level. Always.

33


Remove settings to reduce complexity.

34


Remove hierarchy levels to reduce
complexity.

35


Free the canvas from options menu and
gain screen real estate for main controls.

page.

with a low price.

pocket.

Each setting is a decision you were too
much of a coward to take.

47


There are UI stencils for Inkscape in
addition to Adobe Illustrator.

Asha UI component demo application is a
Java midlet suite for LCDUI.
