Mobile Augmented Reality continuously reveals its potential for practical purposes. Our current case study is one to elaborate the concept of navigation on campus, this time with the help of Apple with ARKit and for android with ARCore . First and foremost, this may be of interest to modern companies and big education university with large premises and hundreds of employees , who need a convenient tool to find the shortcut to the room where an urgent meeting or for students who want to attend different class room , library and different area of university.

How do they find it? Well, they just scan a special marker located in the required building, select their destination, and get the route on their smartphone screen — simple as that.

How is it implemented?

We divided large buildings into specific areas, whose plans are stored on the back end together with the coordinates of mentioned markers and a full list of destinations.

As GPS get approximate coordinates, the app receives AR markers to determine user location in a more precise way. Then, as the user selects their destination, the app calculates and displays the route in augmented reality. As the user walks on towards the destination, the app gets further markers for new areas and updates the precise user location. That's how it's impossible to get lost, however if it is a large or complex the campus is.
