Focusing on three specific filmic optical illusions, each will be studied via a different methodology that best suits it.
forced perspective will be studied interactively
-an applet with 3d models. the user has the ability to move the camera. there will be a scene with two characters, where one will appear larger than the other, but it will be a forced perspective trick.
-a setting called "Moving forced perspective" can be turned off/on. if on, the second character will move in counterpoint to the camera's motion, so that the illusion is maintained, if off, it won't move in counterpoint, revealing the illusion. this can allow the user to discover the limits of what works.
-perhaps the user can manipulate the scale of the characters, perhaps they can be moved closer/farther apart via a sliding bar. there's a few variables to toy with here.
moving background/chromakey will be used in a created illusion
-since you can cause perception of movement where there isn't any, can get really creative here.
-a pre-created illusion
-a couple decent ideas for doing this creatively so far. (star wars repl, real life frogger, moving library, illusory rubik's cube, strt bzr prfm)
eyeline match, studied by papers and experiments
-discovery attributed to the Soviet Montage school of film editing
-popularized by Lev Kuleshov in his famous experiment
-film scholar Kristin Thompson has noted that scholars have theorized a cognitive connection
-cognitive connection seems very likely intuitively, but evidence is fragmentary at best
-possible relations to the 180 degree rule? (is the rule even valid? Ozu, for instance)
