DIGITALLY MARKED OBJECTS AND PROMOTIONAL METHODS

摘要

Physical items can be digitally watermarked, permitting their recognition by webcams or the like to trigger corresponding actions. Coffee cups and coffee cup jackets are exemplary of items that may be so watermarked. The action triggered by recognition of the item can vary, depending on the context in which the recognition occurred (e.g., store or office). The action likewise vary with time (e.g., triggering a first response when presented a first time, and triggering a second, different, response when presented a second time). Some such items may have multiple faces (e.g., tow side to a credit card ; six faces to a product carton) - each encoded with a different watermark and triggering a different response.
