One embodiment of the present invention provides a system for navigating through information associated with physical objects or locations. During operation, the system detects a multi-resolution visual code placed on or in the vicinity of a physical object or location. The system then determines a level of resolution for the detected code, and decodes the code at the determined level of resolution to obtain the information. Subsequently, the system presents the infonnation to a user, thereby allowing the user to navigate through information associated with the physical object or location.
