When you have to find a lost loved one, it needs to be quick and simple. No time to decipher a map and orient yourself, which can sometimes be complicated in a park or in the forest, you have to go straight to the point. Here is where augmented reality (radar) and the compass make complete sense. But to not be disappointed it is important to understand the limits of these features. Presentation.
The main idea: to orient oneself quickly in a research situation
The augmented reality (or radar) and the compass allow you to simply orient yourself in the space in order to find your loved one who has the tracer. They indicate the direction to take and the distance between your phone and the tracker. The information provided is updated with each new position of the tracer received, for real-time guidance.
This data is calculated from the GPS positions of your phone and tracker. The system calculates the distance between the two positions as well as the direction to travel from point A (your phone) to point B (the GPS tracker), exactly when looking for your route to the place of your dinner in your mobile navigation application.
The limits: crazy data at short distance
Any GPS position has a margin of error of a few meters, more or less important if you are indoors or outdoors. In the case of augmented reality and the compass the margins or error that must be taken into account double, that of your phone and that of the tracker.
If you are looking to reach a remote point these margins of error will have a very small impact on the direction to take. On the other hand if the desired point is up to 10 meters ahead of you, it is a safe bet that the indicated direction will be erroneous. Indeed, at a very short distance the margins of error become more important (I join the tracer which is 10 meters away from me, tracer with a margin of error of 20 meters, knowing that my phone has even a margin of error of 15 meters …).
As you can see, these two features are very useful if and only if the tracker is at a distance relatively far from you (at least 100 meters). Otherwise, you may be told that your tracker is not working or that the Weenect application has a problem. You will simply be faced with a limit of GPS technology.
