Augmented Reality (Fall 2022)

HW 8: Commercial app visual coherence

For this assignment, download and try at least one of the following AR apps for your iPhone or Android phone. Below are the company or app websites and app links, you will need to install the apps from the Apple App Store or the Android Play Store.

Evaluate the app with respect to visual coherence and discuss how to improve it using the methods covered in the class. For an AR app to be visually coherent, the virtual objects should blend seamlessly into the real environment to the point where they are indistinguishable from the real world.

Rubric (10 pts)

Discuss the following issues regarding your app (4 pts):

  • Registration – Are virtual objects correctly registered to the real world, such that they don’t drift or “swim” around?
  • Occlusions – Do real objects occlude virtual objects correctly, and vice versa?
  • Lighting – Does the lighting of the virtual objects appear to match the real lighting?
  • Shadows – Do real objects cast shadows on the virtual objects? Do virtual objects cast shadows on the real objects?

Take a picture that illustrates one of these issues, and upload it. Explain how your picture illustrates why the app is or isn’t visually coherent. (2 pts)

Discuss how the issue you chose can be potentially resolved using the methods covered in the class. (2pts)

Finally, read and comment on another person’s submission. (2 pts)
