+<section id="GUID-B8132E14-2B27-4471-BEC8-4975AAB69C76"> <p>In the Symbian
+touch UI, there are two main interaction strategies in use: focus and select,
+and direct selection. Focus and select emulates the functionality of the scroll
+key: the user taps on an item to move the focus to it, and then taps a second
+time on the focused item to initiate the action. In direct selection, the
+interaction happens on the first contact.</p><ul>
+<li><p>In the Symbian touch UI, basic stylus interaction is achieved through
+short tap. In a short tap, the stylus is placed down and lifted up again on
+the same item within a short period of time. </p></li>
+<li><p>When selecting items, for example, from a list, first a short tap moves
+the focus onto a given item and the second short tap performs the set function.
+There is no time dependency between the taps. </p><fig id="GUID-C31EEFC8-CE88-493E-A5EC-25195B7C01D2">

+</fig></li>
+<li><p>In some views, for example in the application menu, short tap selects
+the item directly</p><fig id="GUID-8FF0F504-3E5F-4973-A7EB-66E850F4698B">

+</fig></li>
+</ul><p>Touch down and hold and Touch down and drag are direct selection events,
+where the user taps on the screen and holds the touch for a period of time,
+or strokes the screen without lifting the stylus up. Touch down and hold can
+be used, for example, on lists (see also Lists
+API) to open a <xref href="GUID-BB8B3A11-0BBC-4759-A7F4-A28C9E70573F.dita"><b>stylus
+pop-up menu</b></xref>. </p><ul>
+<li><p><b>Touch and hold</b> functions best as a shortcut to more information
+or options, when manipulating an object. However, as it may not be implicit
+to the users which items have touch down and hold events attached to them,
+the design should not rely solely on the use of these events.</p></li>
+<li><p><b>Tap and hold</b> or <b>long tap</b> can be used for providing, for
+example, contextual options, stylus pop-up menu or help, which can also be
+available through the Options menu. </p></li>
+<li><p><b>Touch down and drag</b> can be used, for example, in applications
+where users move items from one location to another. </p></li>
+<li><p><b>Strokes</b> in different directions or on different areas of the
+touch screen can trigger certain actions. For example, in an image viewer
+application, the user can swipe the screen with the stylus horizontally to
+go to the next or previous image. See <xref scope="external" href="http://www.forum.nokia.com/info/sw.nokia.com/id/567330dd-130f-4f1d-9380-fac5aec5a6a9/S60_Platform_Image_Converter_Example.html">Image converter application</xref> for an example implementation.</p></li>
+</ul><p>The Symbian platform provides the possibility of <xref href="GUID-581A8E4B-12BE-41C0-A20E-3087A80FEECF.dita">tactile
+feedback</xref> for each touch screen event. For more information, see <xref href="GUID-21DAC50D-7737-42B6-BBDA-E12E8779741B.dita">Feedback</xref>.</p><p>In
+addition to the basic touch events and customized strokes, the Symbian platform
+supports <b>sensors</b> which allow for more complicated <b>gestures</b>.
+Gestures involve interacting with the whole device, such as tapping the side
+of the device, or shaking the device. Gestures are not obvious for the user,
+and must be either discovered easily, or communicated clearly.</p><p>Sensors
+can work together with the UI to allow for more complicated gesture combinations.
+When the interaction is based on detecting movement of a handheld device,
+the user interface becomes as tangible as the device itself. This provides
+a new user interface paradigm where the whole physical device can be used
+for performing gestures. For more information, see <xref href="GUID-AE979B97-5610-42F3-99A7-5A3D66D3C2E6.dita">Sensor
+interaction</xref>.</p></section>
