Be consistent with controls

  • Minimize errors and the need for learning by using softkeys according to the appropriate style guide.
  • Build shortcuts for advanced users.
  • Make sure that the most important actions are also available in the Options menu.
Provide useful feedback
  • Let the user know immediately if an action was successful or not.
  • If processing takes more than 0.5 seconds, indicate that something is happening, for example, with a progress bar.
  Hide the complexity of connectivity
  • Short network coverage problems should not cause loss of users’ work or stop them from working.
  • Connection status should be displayed clearly.
  • Synchronization should be automatic but under user control.
Provide a clear navigation model
  • Core features should be available from the main view.
  • Limit the number of menu choices – make them context specific.
  • Navigation model should be focused on the user’s main tasks.
  • Advanced functionality should be hidden from novice users.
  Display softkey labels
Users are likely to be very familiar with the concept of softkeys, and this familiarity should not be wasted. Softkey labels should always be used, even in full-screen mode. A minimalist solution is using a simple symbol to mark the softkey that opens the Options menu.

Use terms consistently
Pay special attention to using terms that are consistent with other S60 applications. Double-check terms used in softkey labels and in the Options menu.

  S60 UI style basic principle 1: Use the navigation key as a primary control.
Users are likely to be very familiar with a five-way navigation key. Users should be allowed to move focus with the navigation key and select items with it. Selecting an item with the navigation key should never result in an action that the user cannot anticipate. Opening a context-sensitive menu is recommended if there is no single intuitive default action.

Pay attention to what you say and how
When designing your application, check that
  • the text is not all in capital letters.
  • the text is not justified to the right.
  • the text is not truncated.
  • the text has good contrast with the background.
