Hi Doug & all,

There have been a few studies, but nothing that has
stretched across all the displays mentioned:

  The first that comes to mind is the work by Randy Pausch 
  published at SIGGRAPH a few years ago.  An HMD with head 
  tracking was compared to an HMD without (if I remember, it 
  was also fixed to a mount).

  Colin Ware, Kevin Arthur and Kelly Booth compared desktop mono, 
  desktop stereo, head tracked desktop mono, head tracked desktop 
  binocular, and head tracked desktop stereo in CHI 93.  

  Yeh and Silverstein compared desktop mono to desktop stereo
  in the SID 90 Digest.

  McWhorter, Hodges & Rodriguez compared desktop stereo to desktop
  mono (and many rendering conditions) in SPIE 1457 ('91).

  Beaton (of VA Tech!) compared desktop stereo and desktop
  mono in the SID 90 Digest.

  Adelson, Allen, Badre, Hodges & Lawrence compared various
  forms of desktop parallax (binocular, horizontal, vertical,
  motion).  Contact Larry Hodges at hodges@cc.gatech.edu.

  Chung compared head-tracked HMD to non-tracked HMD in
  I3DG 92.

Most of these were experiments on basic tasks, not requiring
much interaction.

Not much on HMDs, CAVEs.

Is there any newer stuff out there?

Best,

Ben.
