tactile feedback pulse</title><prolog><metadata><keywords/></metadata></prolog><taskbody>
<context>       <p>The Vibra API clients can request the device to send tactile
vibration pulse using <codeph>PulseVibraL()</codeph> method. The <codeph>PulseVibraL()</codeph> will
be executed only if there is an active tactile feedback settings in the user
profile. The clients can check the current settings by calling the <codeph>VibraFeedbackSettings()</codeph> function.
The overloaded <codeph>PulseVibraL()</codeph> methods allows the client to
:</p><ul>
<li><p>Use the default intensity and duration.</p></li>
<li><p>Use default intensity and specify the duration using <codeph>aDuration</codeph> parameter.</p></li>
<li><p>Specify both intensity and duration using the parameters <codeph>aIntensity</codeph> and <codeph>aDuration</codeph>.</p></li>
</ul><p><codeph>SetFeedbackObserver()</codeph> is used to register the clients
to receive notification of any changes to the tactile feedback settings in
the active user profile. <codeph>MHWRMVibraFeedbackObserver</codeph> provides
a pure virtual function <codeph>VibraFeedbackModeChanged()</codeph> which
is called to notify the clients to notify of any changes to the user profile
settings.</p></context>
