I have been in an interesting twitter conversation on the Swayze effect in Virtual Reality (see https://www.oculus.com/story-studio/blog/the-swayze-effect/)

Very thought-provoking article and it is a real problem, engagement in VR, but Swayze as ghost actually cares, the VR audience doesn’t..

So I suggest to redefine the Swayze Effect: where one wants to interact in VR but cannot, and to use the term Rickman Effect where one cannot or can only slightly interact but one has no great desire to. Alan Rickman’s character in the movie Truly Madly Deeply is a ghost who returns for his partner, but permanently feels cold and spends most of his time on the sofa aimlessly watching TV. See this youtube clip of Alan Rickman in the movie for more of a visual explanation.
