Long distance transfer, opposed to short ranged QR codes

Count on the Japanese to innovate stuff. Brilliant

I really doubt that the Soviets used special "fleshlights"...flashlights maybe...fleshlights are something else altogether!

If light behaved this way, all the hot chicks would vanish. Science man!

I am not sure why this mode of communications limits "up to five people" only.

[andybruintje]

..the thing is. A Qr can be prineted an paper.this cant.

The idea behind this technology is that you can transmit a message to many people at the same time over a relative large distance while using as little space as possible. Something typical for a cramped Japanese environment.

It would be nicer if it was infrared, but cameras in consumer electronics have special filters to block infrared.

Having a big blinking dot on your advert might not be a good idea, because the eyes of the customer would be drawn to the blinking light, failing to attract attention to the message in the 3 seconds window of opportunity. Also if the blinking light is big enough it might cause epileptic episodes in people with epilepsy.

i once wrote a program that was detecting moving objects only to find that the government spend millions of dollars to do the same thing.
