4. GENERAL USABILITY ISSUES – GUIDELINES FOR DESIGN
Nokia Mobile Phones are renowned for their simple to use and intuitive user interface. In order to
create a service that will be perceived as usable and easy to understand, Nokia Mobile Phones provides
some general guidelines to help service providers develop their applications.
4.1 Validate Your WML
There are several XML validators available that validate your documents against WML Document Type
Definition. It is recommended that authors validate their WAP pages, because invalid WML is always
treated as an error and discarded (ie. not shown to the user!).
Several XML validators can be found at
4.2 Site Organization
4.2.1 Avoid ‘doormat’ pages
The user is accessing your WAP site over a GSM data call, and pays per second. It is not recommended
to start your site using a ‘doormat’ page, which has no functionality other than perhaps to greet the
visitor and to display a logo. It is better to go to your service directly. If there's a need to use timer it
shouldn't be timed longer than ~1,5 sec, otherwise add a link 'continue' to give the user possibility to
exit the card.
4.2.2 Automatically Detect the Browser
If you are using a modern web site hosting environment, it is possible to detect the browser as well as
the language mode and supply correct content transparently, without user interaction. 9110i
Communicator display is larger and has more possibilities than usually phone displays that is worth to
take advantage of.
