leARn: a Tool for Teachers

 

Defining the Problem

Students struggling to learn how to manipulate fractions.

Proposed Solution

Giving teachers an AR tool that give students a visual representation of fractions for use in solving fraction problem sets.

My Role

UX Designer/Researcher, Programmer, and Documentarian

Accessibility

In an effort to make this tool as accessible to teachers as possible, we developed it to run on most IOS and Android devices by using print at home fraction cards for image tracking.

Gamified Learning

Using tangible interactions with an application designed to take advantage of reward learning, our system uses tactile, visual, and auditory stimuli to keep students engaged.

User testing and Iterating

Usability testing in-classroom and at project showcases to discover short-comings and create road maps to resolve them making the application more useful.

Wireframing and Interaction Design

  • Initial sketches of wireframe flows

  • Simple touch/swipe interactivity to navigate to specific lesson problem sets

  • UI overlay for the AR camera view with Submit Button for final answers

  • Attempt delayed “Hint” feature and both a success and failure card pop-up with vibration and sound effects. Navigation buttons dependent on problem # within the problem set

App Prototyping/Card Tracking

  • Created target marker cards that 3D AR objects are tracked to

  • Created 3D Fraction models to test the AR tracking and app logic

Usability Testing

  • Partnered with ASU Prep Online to bring the tool into the classroom for testing with students

  • Collected observational data, as well as qualitative and quantitative survey data to find ways to improve the experience
