- The sort of rig thats being described here was developed for
- perception research by Yarbus (1950's) to produce stabilized retina
- images. Basically, a large suction cap contact lens is placed on the
- eye and an image fired onto the retina via a mirror - Firstly these
- lens are certainly not recommended for daily wear - secondly the
- interesting feature of stabilized retinal images is that they
- decay/disappear after 4+ secs due to photosensor adaptation. -
-
- Whatever they were meant to be doing in "Dune" they would have to have
- worked fast. -The point is that eye movement/tremor is important for
- stable perception and not something to try and bypass.
