Bokode Barcodes Use Angular Dimension To Encode Information
MIT Media Lab has discovered a new use for barcodes by shrinking their size and enabling them to encode information in the angular dimension. This could be useful in shops, the classroom, business meetings, videogames, and motion-capture systems. Named Bokode, the system adds a fourth approach to the options for communicating optical data, which include two-dimensional ordinary imaging, time dimension temporal variations, and light wavelength variations.
