    14 is the most important sensory feedback when entering characters on screen.

    15 Visual feedback can be, for example, button effects, color changes, status

    16 indicators, touch/release state changes, or clearing the screen when transitioning

    17 to next screen.</p> <p>With audio feedback, lower clicks and tones are preferred

    18 over loud beeps, though most people turn audio feedback off anyway.</p> <p>Vibration

    19 is used as tactile feedback for touch screen interaction or input. Tactile

    20 feedback gives the user an immediate response that the touch event has been

    21 registered, and can even be given in noisy environments.</p> <p>With the Symbian

    22 touch UI, tactile feedback is used in the following situations:</p><ul>

    23 <li><p><b>Sensors: </b>a double tap on the device by hand provides tactile

    24 feedback to the user in case of a successful interaction</p></li>

    25 <li><p><b>Touch interaction (touch screen):</b> to indicate to the user that

    26 an interaction event has been successful. For example, when the user presses

    27 a button on the touch screen</p></li>

    28 </ul><p><note>Tactile feedback is included in those common UI components where

    29 it has been seen as beneficial. When creating new applications and designing

    30 custom components, tactile feedback is to be included where found useful.

    31 For example, in any button type of UI component, the tactile feedback is naturally

    32 beneficial.</note></p><p>For more information, see <xref href="GUID-581A8E4B-12BE-41C0-A20E-3087A80FEECF.dita">Tactile
