"The Bokodes currently consist of an LED, covered with a tiny mask and a lens...Currently, the tags are expensive to produce - around $5 (£3) each. This is, in part, because the early prototypes require a lens and a powered LED.
However, the researchers believe the technology could be refined so that tags were reflective and require no power."
Which means they'll only be good if illuminated - not necessarily a drawback as current barcodes need light too, but current barcodes make their location obvious. Having a bunch of people walking around with wide-angle flashlights will get annoying.
Maybe, but I doubt my cell phone will photograph in the IR. It will also have to discriminate among potentially many bokodes in an image. On the other hand, I doubt my cell phone will photograph out of focus, so the point may be moot.
On the plus side, I can stand at the head of the aisle and see if any cereal is on sale without having to actually cruise the aisle itself.

The checkout girls have enough problems getting barcodes to scan right.

It most certainly will! - Point it at your (IR) TV remote control at your camera and press a button (watch the display)

ReplyDeleteYou're right, by the way. I meant to come back and 'fess up sooner.
