PointGrab’s PointSwitch

This nifty gadget allows you to control
multiple appliances – lights,
entertainment systems, air-con and
more – from across the room simply
by pointing and gesturing, so you
won’t even need to pick up your
smartphone. PointSwitch uses
motion-detection algorithms with a
standard two-dimensional infrared
camera to accurately identify
your gesture and its direction.
Just remember to turn it off
before you start dancing on
your own in the lounge…
