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) ===
==== 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 '''LLA only mode''' is '''active''', {{UBIK}} ignores all other location updates except the ones from [[#Scanning LLA markers|scanning LLA markers]].
{{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.}}
