How We Prototyped Our First AR App In 5 Days (Part 2/3)

From sketching, deciding all the way to prototyping – this post is the second of three posts in which I’ll explain how we created our first AR prototype.

Here is the first post of this mini-series. Our goal was to learn more about the technologies behind ARKit and ARCore, understand potential use cases and to build an app that users are interested in and willing to test. The whole team was present and we decided to go for Google’s UX design process methodology, which is based on five phases to build a prototype: Unpack, Sketch, Decide, Prototype, Test.

Once we had established our user scenario, we went on to the next steps.


On the second day, we were going into more details of potential user scenarios.

User scenario

Two things we focused on and that would turn into many fruitful discussions:

  • what are potential modes to display information. The options included audio, video, textual information, data points, icons, colors and 3D Animation of objects. We also looked at Leap Motion’s design sprints and how they approach user interfaces.
  • What are users’ intentions to use the app. Is it more of an entertaining motivation? Do they want to get informed?
Iterations of intentions of users and sources of information

While we were discussing these options, our developers would look into the availability of data sources and what frameworks could be used. One decision we made quite early was that we would use ARKit instead of ARCore for now.

We had many ideas and alway checked whether there were better solutions out there already.

User scenarios and checking other services

At the end of the day and after many discussions, we had a rough understanding of how we wanted to go about all these issues by narrowing down possibilities.


Once we roughly understood what options were on the table, we basically found common ground on some issues: What to do, who we do it for, how to do it and what will be the result by the end of the week.

We started prototyping – first on white boards and later on the developers Stephan, Tino and Ronny started playing around with ARKit.


Playing around with ARKit


In a few days, I’ll show you what it turned into and if you want, you can also try it out!
