Howdy Michael, When it comes to death masks, their HRIRs, and localization in the spiritual plane, I won't go there. There's enough in the physical realm to keep me confused. For example, I have a pair of socks with L embroidered on one and R on the other. I have no idea how the sock manufacturer could tell which was which. But so long as I have R and L tattooed on my feet, I can keep things aligned. Shoes, on the other hand, are always trial and error. Seriously (kind-of), there seems to be a dearth of info on auditory-vestibular interaction, particularly the dynamic effects. We "know" that a fixed item is stationary when we move our head, and we know that a moving object is in motion when we stand still (or lie down in the case of a good tracing). Lots of studies of vestibular-vision interaction, and there are certainly ways to trick the mind into believing what ain't true is believable. Re static anatomical plane inversions: I don't believe that a vestibular cue will turn an azimuth interaural cue into a vertical HRTF cue (or vice a versa). But if the vestibular interaction is at the level where all cues are used to determine the total 3D location of the source, maybe vestibular input can correct for where the head is situated (?). As usual, I ask a lot of naive questions. Perhaps I'm like the prisoners in Plato's Cave Allegory who were only allowed to see (or hear) things from a limited perspective. Release from the cave may be too much for yours truly to comprehend. But as long as I turn toward the shadows (or my feet), everything remains real. Best regards, E

If you lie a young healthy person (i.e. 'normal' skin elasticity) on their back and take a copy of their face (a mask). If you place this on your desk (paperweight-like) it may draw comments, but not about it being unnatural. Now hang it on the all. It won't look right and people are likely to say so. Those who have seen 'death masks' in museums might even ask if it is one. (You can extend this ... with strange results ... to parts of the body that are 'normally' clothed ... but that is another matter.) So a trivial example of an audience's automatic (and unconscious) compensation for orientation. Think you now have to do the experiments you've outlined ;-)> Michael or orientation -------------- next part -------------- An HTML attachment was scrubbed...
