By clearing the online documents, it is possible to free up system memory if needed. It can be triggered by pressing the button "Clear online documents" in the general settings tab. Online documents are documents already uploaded to the server. They can be downloaded anytime agian when the client is connected to the server. However, documents classified as offline available will not be affected and will always stay on the device.
== AR Features ==
Opens the Map View and displays Points of Interest (POI's) related to the current location of the mobile device.
== Positioning ==
{{UBIK}} clients use a [[Location_Manager|Location Manager]] in order to gain knowledge about their position, so it can help the user navigate to his/her target.
The user can [[HowTo:Switch_Positioning_Mode_(UBIK_Android)|choose one of different positioning modes]] optimized for different environments.
Most of them incorporate multiple technologies for calculating positions or checking their reliability.
=== Positioning modes ===
* ''Use all'' - uses all available position sources
* ''LLA only mode'' - used for positioning using markers only
* ''Beacon Proximity mode'' - uses iBeacon proximity and LLA only
=== Technologies ===
==== GPS ====
GPS is used as a primary positioning input source for outdoor areas. Its precision depends on the environment and satellite availability. With good circumstances, the accuracy varies between 1 and 10 meters.
==== LLA markers ====
LLA markers basically are QR codes with location data encoded into them - which can be used for positioning when they are scanned.
==== Beacon-Proximity Positioning ====
The Beacon Proximity Mode detects if the user is in the proximity of a beacon. The proximity region is defined by a proximity distance which creates a sphere around the beacon. Whenever the calculated distance to a beacon is smaller than the proximity distance, the user is supposed to be at the position of the beacon. If multiple regions intersect the user is supposed to be at the position of the nearest beacon.
In order to use Beacon Proximity as a Positioning System, Bluetooth Low Energy has to be available and enabled on the mobile device. If a new environment should be equipped with iBeacon-Positioning, an expert has to mount iBeacons on known positions and calibrate the propagation factor of these beacons. Proximity beacons can be configured using [[SYSCLS_PROXIMITY_BEACON]]. {{Version/WinXSince|UWP}}
