Navigation Guidelines

 

Mitsubishi Trium Navigation Guidelines

Provide backward navigation for each card.

Provide an intuitive label, for example Done or Back, to allow the user to use the right softkey for backward navigation. The browser will automatically provide a label of Back assigned to an action of <prev/> - if the term “Back” is not suitable, it may be overridden such

Example 3-13

<do type="prev" label="Done"> <prev/>

</do>

Example 3-13provides an alternative labelling for the right hand key.

Do not rely on being able to override the default backward navigation

Trium browsers vary in terms of their handling of the <do type="prev">

construction. One type will only change the right hand key behaviour if the action is still <prev/>; the other type allows <noop/> and <go/> constructions to be used

also. For safety, handle alternate back navigation using a mechanism similar to Example 3-12above.

Do not define a <do type="accept"> or <do type="options"> task when a <select> element, <input> element, <a> or <anchor> is used.

A <do type="accept"> or <do type="options"> task on some versions of the browser, this will cause the softkey to display the Card label preventing easy navigation to the next card or to the input and select items. Instead, provide a link allowing the user to navigate to the next card.

Limit the number of softkey actions to one.

The browser displays the defined label on the left softkey. This simplifies tasks because the softkey label is accessible with one keypress. When more than one task is defined, the left softkey label may become Card and displays the defined labels. In this case, build a card with the desired tasks and label the softkey Menu. This provides room to display more descriptive labels for each action and enables the use of key accelerators, on some handsets.

Do not underline text (<u> mark-up tag), because the user may think that the item is a link.

Not all Trium browsers will do underlining if the tag is used, but if it does, there is clear possibility for confusion.

Avoid using WML Scripts.

Since the user can disable WML Scripts, do not rely on them being activated. You can check to see if the user has disabled scripts by checking the HTTP_ACCEPT header – however the user could still turn off scripts while a script is in the cache of the phone.
