An augmented reality iOS education application that tours monuments around the D.C. area.

First-Time Hacker Project

Inspiration

Going to see The White House and wanting a unique way of getting information about it Using Augmented Reality our team wanted to present the information and a 3D representation of the building in real time.

What it does

Using AR We used Unity3D to manipulate 3D models of the monuments and attraction in the near by city of The District of Columbia. The 3D model is shown, along with information about the monument, when the following surfaces are shown. One dollar bill: The Washington Monument Five dollar bill: The Capitol Building Twenty dollar bill: The White House

How we built it

We used the Vuforia extension to connect the Unity3D project to images of the bills to be detected as surfaces. We obtained 3D models of the monuments used as examples for this concept. We added cards of information tagged with the model to learn about the following monuments.

Challenges we ran into

-Getting the models to be formatted in Unity3D to be in real time for the correct size and orientation. -Learning about AR and the different ways of approaching the solution to our idea. (We first tried Xcode and ARkit, however we ran into trouble with our models not being compatible and able to show in real time.) -Having a clean track on the surface bills using the surface picture. -Using the Vuforia extension for backend to store pictures and link to using as a tracking surface in Unity3D.

Accomplishments that we're proud of

-The accurate recognition of the specific bill -The accurate tracking of the motion in real time -The Models being tracked and attached to the surface of our choice in real time -The conceptual value and expandability of the results. (Our ideas of branching out to not only monuments as a virtual museum, but also in the world of education. Using AR in a classroom setting for students to get an immersive learning experience with the physical object model in front of them in real life and real time.

What we learned

-AR takes a lot to be even slightly accurate. -Using ARkit with Xcode and Swift and the models that work and do not work with it. -Using Unity3D and using 3D models to track to a surface we set to a picture of using the Vuforia extension.

What's next for CityAR

-Our team sees our project being expanding for throughout the entire city of Washington D.C. and the popular locations and buildings. -As mentioned above, we also see our application's concept being used in many environments. Ex: Classroom/Education, Medicine - being able compare and detect objects, such as body parts, symptoms, medicines, tools, etc.
