Bokode: Imperceptible Visual Tags for Camera Based Interaction from a Distance

A paper presented by members of the Camera Culture Group from the MIT Media Lab at the recent Siggraph 2009, a Bokode is a new kind of small barcode.

Current optical tags, such as barcodes, must be read within a short range and the codes occupy valuable physical space on products. This is a new camera based interaction solution where an ordinary camera can be used to detect small optical tags from a relatively large distance. Tags can be shrunk to 3mm visible diameter, and unmodified ordinary cameras several meters away can be set up to decode the identity plus the relative distance and angle.
