+Location-based [Augmented Reality (AR)](https://en.wikipedia.org/wiki/Augmented_reality) app using [Android Studio](https://developer.android.com/studio) and [Kotlin](https://kotlinlang.org/).
+This project is based on [dat-ng/ar-location-based-android](https://github.com/dat-ng/ar-location-based-android) which is rewritten in Kotlin with some modifications like login using [QR code](https://en.wikipedia.org/wiki/QR_code), getting location data from HTTP server, and icon click.
+But the AR still doesn't have a good virtual impression as sometimes it shows a large error in the accuracy of the location's direction.
+Although, the error actually depends on the updated data from the location service and orientation sensor in the device and it probably could be fixed with a better data acquisition like using [Kalman Filters](https://en.wikipedia.org/wiki/Kalman_filter).
+
+We created this project as part of the Smart Tourism project that consists of several parts like [database server](https://github.com/iruz17/project-telematika), [card scanner device](https://github.com/iruz17/smart-tourism-device), [administrator website](https://github.com/niaangellina/smart-tourism-web), and [location's direction app](https://github.com/threeal/smart-tourism-app).
+Smart Tourism project is a system for smart tourism that improves the impression of tourism sites using an electronic card to enter and exit locations, a website that monitors and show statistic for each location, and AR app for visitors to show location's direction.
+This project is undertaken to fulfill the Telematics Projects course in the [Computer Engineering department](https://www.its.ac.id/study-at-its/faculties-and-departments/faculty-electrical-technology/computer-engineering/) of [Sepuluh Nopember Institute of Technology](https://www.its.ac.id/).
+
+## Project Setup
+
