Sintef Uses Camera Phone To Connect 2D Codes
SINTEF developed in 2001 a system that allowed hundreds of 8-bit bytes to be input into the camera, using a single user-captured image as input.
The system is based on using a specially crafted two-dimensional barcode, which is printed on the desired objects. The image analysis software developed by SINTEF recognizes this barcode, and its content is subsequently input to the mobile phone.
This makes it possible for the user to e.g. scan a business card with a printed barcode, and get the information automatically into his contact list. The system thus enhances the user’s mobile experience by making the mobile phone able to interact with physical objects in the “real” world.
