<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>

<li><p>Multiple touch.</p><p>For more information, see <xref href="GUID-17C64C2F-9426-4B41-9F0A-23060289D644.dita">Multiple touch</xref>.</p></li>

<li><p>Toolbar component in touch UI</p><p>For more information, see <xref href="GUID-EB212C35-5416-4CA7-8091-61B45D78E220.dita">Toolbar</xref>.</p></li>

<li><p>Touch input component (virtual keyboard, hand-writing recognition

and virtual ITU-T) </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 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>

<li><p>Touch-enabled components</p><p>For more information, see <xref href="GUID-BB8B3A11-0BBC-4759-A7F4-A28C9E70573F.dita">Touch support for UI components</xref>.</p></li>

</ul>

<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>
