UI</title><prolog><metadata><keywords/></metadata></prolog><conbody>
<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>Multi-touch</p>.<p>For more information, see <xref href="GUID-17C64C2F-9426-4B41-9F0A-23060289D644.dita">Multi-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>
