For the POI view to function and deliver a satisfactory user experience, a device's processors must meet certain requirements (support [http://www.arm.com/products/processors/technologies/neon.php NEON from ARM]) (. {{Version/AndroidSince|2.4.5}}).
Devices such as the following are known to lack such a technology and, therefore, can not use the POI view.
* Samsung Galaxy Tab 10.1 P7500
</gallery>
Only [[SYSCLS_GEO|Geo contentcontents]] are displayed as billboards, qualifying certain conditions: {{Tip/Version|In versions up to 2. In addition:* An 4.3 an object no longer has had to be in the infrastructure in order to be shown;{{Hint|This was not the case before {{Version/Android|2.4.3}}}}
* If a [[HowTo:Use_POI_Groups|POI group]] is currently open/active, objects that are shown are:
** [[SYSCLS_POIGROUPITEM|POI group items]] that belong to the current group;
** Objects that are '''not ''' POI group items(and do not belong to any group).* If a layer is currently selected, objects that are shown are: ({{Version/AndroidSince|2.5.2}}. Objects are not filtered by layers in previous versions.)** [[SYSCLS_MAPITEM|Items]] of the current Layer;{{Tip/Version| Objects are not filtered by layers in previous versions.}}
** Objects that are '''not''' layer items.
{{Clear}}
When a user touches a billboard, a [[POI_dialog|dialog]] for that particular POI will show up.
=== Scanning LLA markers Optical Markers ===Under certain circumstances, users might want to specify a manual location instead Two types of using the current location detected by their devices. This optical Markers can be achieved by scanning an LLA marker in scanned from the POI view: [[Object Proximity Positioning#LLA_markers|LLA Markers]] and [[AR-Marker|AR-Markers]].The former can be used for device pose estimation ([[Object Proximity Positioning]]), whereas the latter can be used for [[AR-Marker#AR-Marker_Device_Pose_Estimation|device pose estimation]] and [[AR-Marker#Direct_Augmentation|direct augmentation]].
=== Action items (Android) ===
==== Layers button ====
[[File:map_layer_dialog.png|thumb|alt=Layer dialog|Layer dialog]]
{{Version/AndroidSince|2.5.2}}
Geo content can be configured on the server side to belong to a certain layer.{{Version/AndroidSince|2.5.2}}
By pressing the layers button, a dialog containing all the available layers will be displayed. By checking/unchecking the layers in the dialog box, users can filter out content that belong to the unwanted layers.
==== Compass calibration button ====
{{Version/AndroidSince|2.4.15}}/{{Version/WinXSince|2.5.4}}
This button can be used in order to calibrate the compass, e.g. for a demonstration use case or if it points in the wrong direction.
When it is clicked, the compass will behave as if the current heading was north(for WinX see [http://wiki.augmensys.com/index.php?title=Settings#tab=WinX| CalibrationHeading] setting). Technically, as a compass offset setting is used in the background.
Therefore, in order to use it, do the following:
* Turn the device so it looks at where you want it to believe that north is.
* Click the button.
==== LLA only mode button ====

When If '''LLA only mode''' is '''active''' when entering the POI view the toggle button is not shown. If '''LLA only mode''' is '''inactive''' when starting the POI view, there should be is a toggle button in the POI view:* A single click on it would switch {{UBIK}} from the current [[Location_Manager#Possible_positioning_modes|positioning mode]] to LLA only mode (PositioningMode set . {{Tip/Version|In versions 2.4.3 to LLA_ONLY_MODE2.4.6 a single click would switch {{UBIK}} from the LLA only mode to the default positioning mode (defined in the factory settings);.}}
* Another click from LLA only mode to the previous mode.
Since {{Version/Android|2The toggling of the positioning mode only happens within the POI view.4When the POI view gets in the background (either by closing or by opening a different view) the initial positioning mode gets applied.3}}:
When '''LLA only mode''' is '''active''' and the default positioning mode is '''not LLA only mode''':
* A single click on it would switch {{UBIK}} from the LLA only mode to the default positioning mode.
* Another click from the default mode to the LLA only mode.
Since When '''LLA only mode''' is '''active''', {{Version/AndroidUBIK}} ignores all other location updates except the ones from [[#Scanning LLA markers|2scanning LLA markers]].5{{Hint|During LLA only mode, {{UBIK}} stops most of its location services. However, services such as GPS require a long initializing time before they can be used. Considering the fact that LLA only mode is often switched on and off for a short period of time, {{UBIK}} keeps such services on "standby" for a while so that the mode switching is smooth and instantaneous.2}}:
When '''LLA only mode''' is '''active''' and the default positioning mode is '''LLA only mode''' the button is not visible in the POI view. When the POI view gets closed or another activity opens (e.g. settings) the initial positioning mode gets applied.
When '''LLA only mode''' is '''active''', ==== Location Mode Indicator ===={{UBIK}} ignores all provides an indicator showing the user if LLA only mode or any other location updates except positioning mode is currently active. This indicator is toggled by clicking the ones from [[#Scanning LLA markersLLA_only_mode_button|scanning LLA markersonly mode button]]. {{HintVersion/AndroidSince|2.5}} {| class="wikitable" | width = "25%" style="text-align: center;"|-!
