    13 tactile feedback pulse</title><prolog><metadata><keywords/></metadata></prolog><taskbody>

    14 <context>       <p>The Vibra API clients can request the device to send tactile

    15 vibration pulse using <codeph>PulseVibraL()</codeph> method. The <codeph>PulseVibraL()</codeph> will

    16 be executed only if there is an active tactile feedback settings in the user

    17 profile. The clients can check the current settings by calling the <codeph>VibraFeedbackSettings()</codeph> function.

    18 The overloaded <codeph>PulseVibraL()</codeph> methods allows the client to

    19 :</p><ul>

    20 <li><p>Use the default intensity and duration.</p></li>

    21 <li><p>Use default intensity and specify the duration using <codeph>aDuration</codeph> parameter.</p></li>

    22 <li><p>Specify both intensity and duration using the parameters <codeph>aIntensity</codeph> and <codeph>aDuration</codeph>.</p></li>

    23 </ul><p><codeph>SetFeedbackObserver()</codeph> is used to register the clients

    24 to receive notification of any changes to the tactile feedback settings in

    25 the active user profile. <codeph>MHWRMVibraFeedbackObserver</codeph> provides

    26 a pure virtual function <codeph>VibraFeedbackModeChanged()</codeph> which

    27 is called to notify the clients to notify of any changes to the user profile

    28 settings.</p></context>
