    13 <p>Visual feedback is the most important sensory feedback when entering characters

    14 on screen. Visual feedback can be, for example, button effects, color changes,

    15 status indicators, touch/release state changes, or clearing the screen when

    16 transitioning to next screen.</p>

    17 <p>With audio feedback, lower clicks and tones are preferred over loud beeps,

    18 though most people turn audio feedback off anyway.</p>

    19 <p>Vibration is used as tactile feedback for touch screen interaction or input.

    20 Tactile feedback gives the user an immediate response that the touch event

    21 has been registered.</p>

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

    23 <ul>

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

    25 to the user in case of a successful interaction.</p></li>

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

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

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

    29 </ul>

    30 <p><note>Tactile feedback is included in those common UI components where

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

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

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

    34 beneficial.</note></p>
