With an interface...

Minimize navigation paths

Avoiding multiple methods of navigation may initially appear to be a boon to users by accommodating a larger variety of learning and interaction styles. However, it also makes it more difficult to learn how the user interface is organized, thereby increasing the likelihood of errors and decreasing efficiency, utility and enjoyment.

Additionally, providing too many methods of navigation can increase cognitive load as the user needs to focus on remembering which of several methods will get them where they want to go as well as the history of how they go to that point if they want to return to an earlier step.

• Ensure that key functions and features are visible and easily accessible

• Use caution when creating user interface hierarchies that are deeper than three levels (e.g., main menu à inbox à message content)

• When possible, minimize navigation to one visible primary means of navigating and one advanced method that allows for faster – though less discoverable – means of navigating (in some cases, dedicated hardware keys may provide a third means of navigating)

• Navigation elements should be clearly distinguishable from all other user interface elements
