The problem PathMarkAR solves

Problem:

When we use Google Maps to reach an unknown place, sometimes we are near the destination but we cannot figure out where exactly is the destination.
While visiting a new mall, you want to visit a particular shop. Even with the directions and signboards, you cannot exactly figure out where it actually is.
Multiple gates and terminals on the airport can sometimes be hard to locate.

Solution:

We developed a hack which allows users to simply take out their phones, select the destination and navigate through with markers in augmented reality while following a 3D character.
It’s easier to navigate indoors when you can see your surroundings rather than using maps.

Challenges we ran into

There was an issue with the version of Unity and ARCore. Due to this, our app was totally unresponsive and even after lots of debugs, we could not pinpoint the issue. We solved the problem by running the previous version of Unity and it worked.
One needs to carefully check the version compatibility before start working.
