I recently made a pair of web-based applications to showcase the capabilities of augmented reality (AR). These applications were created as an effort to engage new students when they visited the Center for Immersive Media for the first time. It ended up being a great way to peak their interest and encourage them to think about new technologies as artists.
Objectives
The objectives were relatively simple, demonstrate both fiducial marker tracking and world tracking. Its always good for engagement for folks to leave with a artifact, hopefully they'll hold on to it and be reminded of their experience every time they cross paths with it. With that idea in my head I decided to create a "Post Card" take away for students that would cover fiducial marker tracking. For world tracking, I made the decision to try incorporating a little performance into the application. Given that we have an optical motion capture system at the Center for Immersive Media, it wouldn't be too hard to leverage some captured material.
Quick note: The WebXR API does not have support across all major browsers. Creating Augmented Reality experiences on iOS is particularly difficult since Apple require all iOS browsers to be based on Safari (or WebKit I guess). Many of the examples were created using a licensed XR library (8th Wall or Zapworks).
