+<p>When designing a Symbian application, the UI must be designed so that everything
+can be done 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 OS involves a number of 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 include the following:</p>
+<ul>
+<li><p>Resistive touch screen (HW) </p></li>
+<li><p>Capacitive touch screen (HW)</p></li>
+<li><p>Toolbar in touch UI (component) </p><p>For
+more information, see <xref href="GUID-EB212C35-5416-4CA7-8091-61B45D78E220.dita">Toolbar</xref>.</p></li>
+<li><p>Touch input (virtual keyboard, hand-writing recognition and virtual
+ITU-T) (components) </p><p>For more information,
+see <xref href="GUID-57B7DA8C-A62F-4C65-B754-47D9F5E76416.dita">Text input</xref>.</p></li>
+<li><p>Stylus pop-up menu (component) </p><p>For
+more information, see <xref href="GUID-C4E728B4-3E84-49A4-83CB-DF146420D78A.dita">Stylus
+pop-up menu</xref>.</p></li>
+<li><p>On-screen dialer (an application) </p></li>
+<li><p>Additional touch functionality to some components (for example, Preview
+pop-up) </p><p>For more information,
+see <xref href="GUID-E7EFAD50-3323-49A6-A5D9-95B95F0FBF0E.dita">Preview
+pop-up</xref>.</p></li>

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