Abstract:
A cellphone with a camera takes a photo of a barcode in a screen that can show different images. The barcode is decoded into a URL, and the cellphone uses wireless Internet access to visit the website of the URL. The website then makes a different image, that also has a barcode of a URL, and sends it to the screen for display. This can increase the interactivity of the screen and its value to advertisers. Several users with cellphones might simultaneously interact with the screen in this manner.
