What sort of interest would people have in an HMD using low-power
lasers to give 1000x1000 monochrome drawn straight on the retina at
60Hz?  (Based on the recent report announced on the group)

It is possible the field of view could be increased without bending
optics by increasing the scanning step and de-focussing the laser to
produce larger pixels (this would blur the image but most HMDs do to a
certain extent).

(Thinking aloud...) at about 135-145 degrees per eye each pixel would
cover around 7 degrees horizontally and probably less vertically for
FULL field of view.  Hmm.. not good for detail.  What if it was
adjustable? (by software?) the software would no longer need to
accomodate the lens distortion though, so maybe the image could be
scaled differently for horizontal and vertical and still be faster.
HMMMM......

Maybe an advanced eye tracker could offset the image on the eye so you
could concentrate the 1000x1000 on the relevant centres.....
