The
ultimate in video is a system that renders
three-dimensional images in real-time and
lets the viewer change viewpoints at will.
It takes a lot of network bandwidth to transmit
that much information, however. A system that
turns two-dimensional pixels from a camera
array into a set of independent points in
space promises to lighten the load.

Internet
ups power grid IQ
Buildings usually consume electricity without
much in the way of planning or policy. But now that
most building are wired into the Internet the way
is open for building managers to program buildings
to adjust power use dynamically based on infrastructure,
economic and environmental conditions. A test using
electricity price hikes shows the possibilities.
Fractals
show machine intentions
Someday machines could build themselves,
which means they might not necessarily be designed
to communicate with people. This could make interacting
with machines difficult. One solution is to give
people a means of interpreting machines that's similar
to the way we read each other's body language. A
team of researchers has proposed a way to do so
that combines fractals with algorithms that automatically
cluster data.
VR
tool re-creates hallucinations
Psychiatrists face the difficult task of
putting themselves in the shoes of mentally and
emotionally disturbed people. A virtual reality
program that reproduces patients' hallucinations
can give them a first-hand experience, and it gives
them a tool to help treat the patients.
