  • Patent number: 7374087
    Abstract: Embodiments of the invention recite a method, apparatus and system for conveying cartridge notification. In one embodiment, a permanently encoded pattern of location information embedded on a printed medium is recognized using an electronic interactive device. Note that the encoded pattern identifies an application. A determination can be made as to whether the electronic interactive device has access to the application based on its memory and the memory of an attached cartridge. In response to the electronic interactive device not having access to the application, it is determined based on a cartridge lookup table of which cartridge includes the application. A message can be conveyed regarding the cartridge to the user. The cartridge lookup table may be populated with information regarding the application contents of various cartridges in response to these cartridges being inserted into the interactive device.

  • Patent number: 7281664
    Abstract: A method for hierarchical management of a plurality of regions of an encoded surface. The method includes recognizing unique encoded information on a portion of the surface in response to a pen computer touching down on the portion. A unique location of the portion of the surface is determined based on the unique encoded information. A region is determined out of the plurality of regions for the location. Upon the determination of the region, a determination is made as to whether the location is within a sub-region within the region. If the location is within a sub-region, a function of the pen computer is performed based on the sub-region. If the location is not within a sub-region, a function of the pen computer is performed based on the region.
