4.3.2 Use Reasonable Tables Sizes
If the table size exceeds the maximum width of WAP services application screen due to number of
columns the table size will be scaled down to fit the screen. To keep the cell content readable, special
attention should be paid on table structuring.
4.4 Use of card titles and element labels
Card titles describe the content of the display and their use is recommended. They help the user to
navigate in the application because they function as a reminder of where the user is in the application.
The header text should be determined by the item previously selected by the user. For instance, the
card title ‘Bookmarks’ tells the user that the display contains a list of bookmarks in the application and
that the Options item previously selected was Bookmarks.
Proportional fonts are used in header texts, and if the header text is too long it is automatically
truncated. Truncation is usually better than abbreviations, because the user might be confused by
unfamiliar abbreviations that can be difficult to understand.
4.5 Perform usability test
It is always good to perform a usability test of new applications. People who have not been involved in
the design or development of the applications tend to notice potential usability problems often not
obvious to those who know the design by heart. Usability tests should always be performed as early as
possible in the development process. Any necessary changes resulting from the tests can then be
implemented within the development timescale. Try to recruit users who are representative of the end
users of the application, and try to conduct the usability test on a smaller scale, if the timescale does
not allow for extensive testing.
5. NOKIA 9110i COMMUNICATOR USER INTERFACE ELEMENTS OF WML
This chapter is a guide for using WML in designing services specially for Nokia 9110i Communicator. It
is an overview of the graphical user interface elements and their WML capabilities supported by the
browser so the document doesn't include all possible WML elements and attributes. WML Version
supported in 9110i is v1.1.
The elements are shortly described and shown in example figures and WML code. The code examples
include only the essential part in using the elements ie. the document prologue is not shown after
example 1.
5.1 Display and Formatting Elements
WAP service features include a display size of a 640x200 pixels, lines of text for data 8 and
approximately 60 normal characters are suited per line. The pixel shape is rectangular and the pixel
pitch is 0,17mm. The display can be scrolled vertical with the arrow key and for selecting there is a go-
button.
The screen has an indicator pane on the left and the soft button pane on the right. The vertical scroll
bar is visible if the card does not fit on the screen all at once.
The title row is divided in two parts. On the left, the title of the card is shown. On the right, the title of
the currently active element is shown.
