May I suggest a small but important shift in the way of thinking of
imaging on the displays. Instead of referencing the image to coordinates
established from the edges of the screen, think of the edges of the
screens as addressing locations in a larger virtual world.
(i.e. "a temporal texture space")
Use the accelerometer to "move the frame" in the larger space. This is
an oldish idea that I have seen revived several times in the last
decades. (e.g., Jaron Lanier described it to me a few years ago and Sun
research did it in a PDA prototype before that). Now the displays that
are hanging like bats in a cave can be swung from pendulums or blow
around in a breeze (there are some nice energy effficent
rigs for this with muscle wire). This motion is important for me for
two reasons, it can be used to create experiences like
the shimmer of leaves blowing in the wind where the matt and shiny sides
modulate temporally (also fields of wheat) but also it defeats
a problem I have with screens in theatrical contexts which is most
apparent in the "magic mirror" trope when activity in real space in
front of the screen is transformed and reflected back behind the real
actors/dancers. The problem is that the screen is anchored
and the action isn't so when you move your head the screen reveals
itself throughout the image instead of framing the image
thus defeating the necessary suspension of disbelief for cohabitation of
the screen information and the action. This is analogous to the sweet
spot and uniform directivity problems in audio that we have been
tackling.
competitors coming out. HP has one
coming out real soon and a lot of programmers I know prefer other OS
development tools for such things.Finally, remember if you are willing to live with lower overall lifetime
of the leds (a year or two instead of 4 or 5) you can increase the
backlighting brightness considerably:
