-with other hardware components</title><prolog><metadata><keywords/></metadata></prolog><conbody>
-<p>In addition to traditional keys, interaction devices of other types may
-be built in the devices. In most scenarios, they produce input events similar
-to keys, so that the software need not be changed. The hardware commands do
-not have any effect on the application.</p>
-<p>Examples of specific interaction devices are:<ul>
-<li><p>Optical joysticks</p></li>
-<li><p>Optical 9-way finger navigation</p></li>
-<li><p>Acceleration sensors</p></li>
-</ul></p>
-<section id="GUID-C70CF894-EACC-470A-98C7-846B7FBC4F04"><title>Optical joystick</title><p>An optical joystick can be used
-instead of (or in addition to) the traditional navigation keys. </p><p>When
-used in combination with traditional scroll keys, optical joystick performs
-same functions as that of mechanical scroll keys. However, the speed of the
-movement can differ. </p><p>When used individually as the only scrolling device,
-optical joystick emulates the functions of mechanical scroll keys. Sliding
-a finger down over the joystick provides the same function as that of pressing
-the down key. Repeat functionality can be produced with longer strokes. </p></section>
-<section id="GUID-DF3C81F4-2FAD-4373-8568-0CFC6C7F9618">       <title>Optical
-9-way navigation</title><p>The Symbian platform supports additional optical
-navigation that is integrated to centre Select key. The supported directions
-in 9-way rocker key are domed main directions and diagonals by combining the
-main directions. Optical navigation allows continues moment of the finger
-as observed in touch pad. It is suitable for pointer moving in browser and
-content panning, for example, in photos, browser, and maps.</p></section>
-<section id="GUID-10494E4E-B037-4874-BEFB-20AB95B61CBA"><title>Acceleration
-sensor</title><p>There are three types of interaction events that can be recognized
-with acceleration sensors:<ol>
-<li id="GUID-704B967F-7E70-4446-B443-DDCA665D80BE"><p>Tapping the device by
-hand (double tap) to perform a given function in set events. Tapping interaction
-is not recommended for touch devices to prevent the unintentional touch actions.</p></li>
-<li id="GUID-43884A1A-DE03-4074-8D35-4C5254159F14"><p>Changing the device’s
-orientation from portrait to landscape and back to perform screen re-orientation.</p></li>
-<li id="GUID-C07401D7-3AD2-4D74-B61D-E08A95F4E504"><p>Changing the device
-orientation from screen up (for example on a table) to screen down and back
-to silence an alert tone (for example, silencing an incoming call).</p></li>
-</ol></p>The system is capable of sensing any of listed events. The supported
-sensor interactions are configurable per device, but must be consistent in
-not assigning different functions to these standard events. Also, the user
-can be provided with the option to set the desired interactions. For example,
-it is possible to set methods 1 and 3 (double tap by hand and turning the
-screen downwards) for the 'silence incoming call' event. The settings are
-available in <b>General Settings</b>. A double tap on the device produces
-tactile (vibrating) feedback to reinforce and acknowledge that the interaction
-is successful. See <xref href="GUID-581A8E4B-12BE-41C0-A20E-3087A80FEECF.dita">Tactile
-feedback</xref> for more details.</section>
