Visual Tagging

Semacode is a system for ubiquitous computing. Semacode's software provides the tools necessary to build applications that combine aspects of the virtual world into the real world. It works by combining existing standardized elements — camera phones, optical barcodes, URLs — into an integrated system.
The design philosophy of semacode follows the "small pieces loosely joined" principles
Semacode works by embedding a URL (web address) into a sort of two-dimensional barcode which looks like a dense crossword puzzle (pictured) — called the tag. The SDK software contains the capability to detect and decode the tag very rapidly with the camera on your phone. It extracts the URL and sends you to that address using the phone's built-in browser.
