During my time at Disney I was involved in a few play tests for different park experiences in the AI Character Studio. I am not able to share much details about the the play tests as they are all super early and in development. In these meetings I was often wanting to see more immersion so I offered my prop making experience too my boss, who then assigned me to make several props in order to aide in the immersion for the play testers. I cannot go into any detail about this, however, I can show some pictures of my prop used for an unnamed project.
