Dear Damon,
My impression is that the gaze website is interesting only to people interested in visual processes in isolation from use of visual information for action. If you want to know about visual processes as they relate to body action, studying the eyes and visual processes per se doesn't get you there, and you have to study how the brain and body uses visual information for motion planning and execution. This at least requires technology that tracks the HEAD / NECK as well as the GAZE direction of the eyeballs.
Dr George Shoane at Rutgers Biomedical Engineering gets this, but
Dr Joan Vickers at the University of Calgary and Dr Debbie Crews at Arizona State University do not get this.
The hologram website is very interesting because it focuses on motion parallax as a determinant of depth perception. The visual system is really not 3D, but more like 2.5D, since everything we "see" is in front of our eyes, and we cannot see the backside of things. A hologram shows the backside, but in order to do this, the image must "rotate" and hence motion parallax becomes key. So for putting, this website is more about spatial awareness and the way inherent limits of the visual system can be overcome to a limited extent for sharper spatial awareness. That's a good thing for many areas, including putting.
Cheers!
