Similar to the [[POI_View|POI view on our other {{UBIK}} clients]], the Xamarin version displays Points of Interest (POI's) based on the current location of the mobile device.
A typical POI view consists of a real time camera view and a number of floating POI's.
= POI =
A POI is presented as a billboard which is sometimes also referred to as a bubble. By default, it visually contains some information about the object it represents. For example, the name, the description, the status color.
{{Hint|We mention "by default" because the POI's can be customized to your liking.}}
There are several types of POI's.
== Geo POI ==
For all objects carrying [[SYSCLS_GEO|Geo coordinates]], the app calculates their relative distances and orientations to the device. Based on that information, POI's are displayed for those that are visible to the user in a similar way objects are perceived by us in the real world.
* The closer/further an object is, the bigger/smaller the POI gets;
* Once too far away, the POI is not shown;
* Those that are behind/above/below the user/device are not shown.
The UI of these POI's can be customized in UBIKWorldViewItemArea.xamlx.
== Optical POI ==
Some objects are associated with certain optical codes, e.g. QR codes. The app displays POI's for such objects whenever the corresponding optical markers are detected/scanned. The POI's are always positioned close to the markers.
=== Simple optical POI ===
Such optical codes include [[SYSCLS_OBJECTWITHIDMARKER|barcode, QR code]] and [[SYSCLS_OBJECTWITHOCRTEXT|OCR text.
The UI of these POI's can be customized in UBIKDisplayViewItemArea.xamlx.
=== AR marker POI ===
Compared to other simple optical markers, AR (Aruco) marker POI's can make use of the additional information detected from the markers, namely the marker's relative distance and orientation to the device. Also, the placement of the POI's is more flexible and can be tailored. For details of such POI's, please refer to [[AR-Marker]].
The UI of these POI's can be customized in UBIKCameraViewItemArea.xamlx.
