+<p>When designing a Symbian application, the UI must be designed so that all
+tasks can be performed with touch. Therefore, the design must not rely on
+hardware keys (except for turning the power ON and OFF).  </p>
+<p>The touch UI in the Symbian platform involves various specific touch components,
+component and UI behavior changes, layout changes and additions to the <xref href="GUID-0D093C3D-4D85-455E-B685-064A9B25B1FE.dita">user experience</xref>. The
+main differences or additions in touch UI include the following:</p>
+<ul>
+<li><p>Resistive touch screen (HW).</p><p> For more information, see <xref href="GUID-1FCD0312-7B28-47F9-BE54-822B74A8934C.dita">Designing applications for
+touch UI</xref></p></li>
+<li><p>Capacitive touch screen (HW). </p><p>For more information, see <xref href="GUID-1FCD0312-7B28-47F9-BE54-822B74A8934C.dita">Designing applications for
+touch UI</xref></p></li>
+<li><p>Single tap. For more information, see <xref href="GUID-F66AC845-58B8-4029-AE04-C283226B7C12.dita">Single
+tap</xref>.</p></li>

+virtual ITU-T) </p><p>For more information,

+<p>There are two generic layouts for touch UI -portrait orientation and landscape
+orientation, see the following figure. The <xref href="GUID-771AF721-E2D7-41C8-BF97-5BD30D1A28AD.dita">Status
+pane</xref> in Touch UI has three variants: extended, flat and small.</p>
