Genie 7110 manual Backward Navigation

Backward Navigation 7

Pay special attention to backward navigation because users tend to use the Back key or softkey to back out of an application. Users are more likely to trust applications with good backward navigation functions. In addition, backward navigation lets users leave the application without returning to the home deck. This may be particularly helpful for applications that are deeply embedded in the browser. For example, if a set of applications is three menus deep from the home card, backward navigation allows the user to return easily to the start of the set without re-navigating through the first two or three menus. In some cases, the design must prohibit navigation behind password-protected cards.

The default behaviour for all three browsers vary amongst each other and depending on the how the code is defined:

Backward navigation is not possible.

User must select Home from the Options menu to exit the application.

Right softkey, labelled Back, returns user to the previous card in the history. On some phones, if user navigates over a link, <input> or <select> element, the back functionality is removed.

Left scroll key returns user to the previous card in the history.
