Khoji - Location tracking and visualization using Augmented Reality

An android app, that tracks the location of a user and updates it in the Firebase Database. As soon as the location of the user gets updated, this update is reflected down to all the contacts of that user so they are able to see where that person is at the moment.

We use Augmented Reality, using ARCore, to visualize the location markers of the users so it is easier for them to locate their contacts.

We have also included Real-time chat, as well as integrated a chat-bot into the application.


To better understand the project and to see all the features, you can take a look the project report. You can find the complete report here: Khoji Report/Khoji Report.pdf There is also a presentation that will highlight the main features of the app and provide some demos as well. You can find it here: presentation/FYP.pptx
