     DETAILED DESCRIPTION 
     It will be apparent to those skilled in the art that many uses and variations are possible for the system and method disclosed herein. The following detailed discussion of various alternative and preferred embodiments will illustrate the general principles of the invention. Other embodiments will be apparent to those skilled in the art given the benefit of this disclosure. 
     Recently, printed publications have been fitted to connect electronically with computers  12  and other media output devices (such as display devices or audio devices) to retrieve and display digital content (such printed publications shall be referred to as “interactive hybrid printed material” or “IHPM”). In some instances, the IHPMs  10  have an integrated remote control device capable of interacting wirelessly with the media output devices (herein, a “remote interactive hybrid printed material” or “remote IHPM”), and in other instances, the IHPMs  10  are tethered to the media output devices with a local connection such as a USB connection or cable connection. This technology enables, for example, a reader to press the pictures, icons and words on the regular printed ink and paper page and retrieve digital content from a computer, storage device or other media output device. Examples of such IHPMs  10  are described in U.S. Pat. Nos. 5,624,265, 5,757,304, 5,749,735, 5,763,112, 5,788,507, 5,839,905, 5,911,582, 5,957,695, 6,327,459 and 6,650,867, the disclosures of which are incorporated by reference. 
     For example, an exemplary remote IHPM  10  generally includes a remote control circuitry, a printed publication having printed content, and a membrane switch (for example) connected to the remote control circuitry. The remote control circuitry is capable of transmitting a wireless signal to a host device  12  wherein an application running on the host device  12  displays the desired results. The membrane switch of the interactive hybrid printed material  10  has an association with printed text and/or graphic content on the remote control. The function and/or data indicated by the text and/or graphic content associated with the pressed membrane switch is used by a host device  12  in displaying associated electronic content. The associated electronic content is encoded in one or more remote storage media  14 . The interactive hybrid printed material  10  allows a user to simply activate the membrane switch (e.g., push button or touch sensitivity pad) on the interactive hybrid printed material  10  to cause the host device  12  to access electronic content from a remote server  14  or storage device  14 . 
     A remote interactive hybrid printed material  10  includes a remote control circuitry, a printed publication having printed content, and a membrane switch connected to the remote control circuitry. The membrane switch may be any type of device capable of sensing and responding to pressure—for example, a push button, koala pad, or touch sensitivity pad. In an exemplary embodiment, the membrane switch of the interactive hybrid printed material  10  has an association with text and/or graphic content on the remote interactive hybrid printed material  10 . The associated electronic content and the membrane switch have a remote electronic association implemented through a wireless signal encoded with the remote interactive hybrid printed material  10 . It is also within the scope of the invention to utilize any alternative touch-sensing or location sensing device in place of the membrane switch. 
     An exemplary embodiment of the present invention may also utilize the locally connected interactive hybrid printed material  10  in place of the remotely connected device. The locally connected IHPM  10  likewise includes the printed publication having printed content and the membrane switch; however, in place of the remote control circuitry of the remote IHPM  10  is circuitry that transmits the touch location and other information over local connections. 
     When the user touches the text and/or graphics on the interactive hybrid printed material  10 , pressure from the touch actuates the underlying membrane switch. In response to the activation of the membrane switch, the circuitry of the interactive hybrid printed material  10  generates and transmits a signal to a host device  12 . As used herein, the term “host device”  12  is intended to mean any electronic device such as a computer, television, personal digital assistant, or cell phone that is able to output or display digital content. The signal from the remote interactive hybrid printed material  10  carries data (e.g., x and y coordinates) indicative of the touched location and/or the touched item on the interactive hybrid printed material  10 . 
     In accordance with the present invention and  FIGS. 2 and 3 , an open source publishing method and system is disclosed that allows individuals (such as customers) to select digital content objects from a database of available digital content for use in the development of interactive hybrid printed material  10 . The present invention further discloses a depository for digital content (an “open source library”  16 ). This open source library is accessible through and/or stored on a network resource, a server device  14 , a website, a hard drive, or any other storage device. 
     As used herein, “digital content” refers to the content that resides in the digital space and is available to be retrieved and displayed upon actuation of the membrane switch on the interactive hybrid printed material  10 . Instead of relying on outside publishers  26  to provide the digital content available to be retrieved and displayed on a host device  12 , individuals  18  may choose from digital content in an open source library  16 . The digital content present in the open source library  16  may be shared amongst the users  18  of the open source library  16 . 
     In an exemplary embodiment, the present invention provides a printed publication having printed content, a storage device  14 , an interactive user device  10 , and an output device  12 . The printed publication having printed content in correlation with the interactive user device  10  (such as an IHPM) allows a user to actuate the membrane switch of the interactive user device  10 . This actuation of the membrane switch causes one or more retrieval signals to be generated. These retrieval signals may correspond to the printed content corresponding to the actuated membrane switch. The storage device  14  may include a content database  16  (or open source library  16 ) containing digital content. The interactive user device  10  is in communication with the storage device  14 . The interactive user device  10  communicates with the storage device  14  to determine what digital content is associated with the actuation of the membrane switch and where the associated digital content is located in the storage device  14 . After determining the location of the associated digital content within the storage device  14 , the digital content is retrieved and transmitted to the output device  12 . The output device  12  may be one or more of a computer device, a display device, an audio output device, a video output device, or other similar device. 
     One exemplary aspect of the present invention includes the ability of many users to access the content database  16  of digital content. The digital content stored within the storage device  14  may be associated with the printed content. While the printed content of a printed publication remains constant, the digital content corresponding to the printed content may changed by the user. This may be accomplished by associating digital content with a specific printed content item. The user may then store this association and the location of the digital content in a mapping database  22 . The mapping database  22  is essentially a road map for directing an interactive user device  10  to the location of the requested digital content. Such a mapping database  22  may be implemented by many well known methods. One such method may be a Structured Query Language (SQL) database having records of each of the associations and digital content locations. In response to queries, this mapping database  22  may transmit the association and/or the location of the digital content to the requesting device. Upon receiving the location of the digital content, the output device  12  may output a representation of the digital content. 
     In an exemplary embodiment of the present invention, a user  18  may select from existing digital content that is present in the open source library  16  in order to create an interactive hybrid printed material  10 . In other embodiments, a user  18  may also write, design, and/or create digital content and place or store this digital content in the open source library  16  for public use. 
     In another exemplary embodiment, the digital content deposited or stored in the open source library  16  is meta-tagged or categorized (such as by keyword) so that the content in the library  16  becomes searchable. In a particular embodiment, the content is meta-tagged (perhaps during the submission process) so that another user  18  can do a keyword search in order to locate content of interest. Meta-tagging may include creating a database for storing records of the digital content and associated keywords. This search database may be implemented by many well known methods. One such method may be a Structured Query Language (SQL) database having records of each of the keywords in relation to the digital content. In response to queries, this search database may transmit the keywords and location of the related digital content to the requesting device. For example, a developer of an interactive hybrid printed material  10  on butterflies may go to the open source content library  16  and search for “butterflies.” This query upon the search database may result in responses corresponding to the keyword “butterflies.” The results may include, for example, butterfly video clips from children in New Zealand, an audio description of migrating Monarch butterflies from a college professor, etc. In another embodiment, the library  16  may allow full-text searches of the digital content. 
     In yet another exemplary embodiment of the present invention, the individual developing the interactive hybrid printed material  10  is enabled to determine the needs and/or wants of the customer  18  and select from the open source library  16  the digital content to fulfill those needs and/or wants. In this sense, the individual developer can be thought of as the author. 
     As seen in  FIG. 2 , the customer  18  or user  18  of the interactive hybrid printed material  10  can be the author  18  of the material  10 . With the use of the open source library  16 , the customer  18  or user  18  of the interactive hybrid printed material  10  can determine his own needs and/or wants and select from the library  16  the digital content to meet those needs and/or wants. In this sense, the customer  18  can also be thought of as the author  18  of the interactive hybrid printed material  10 . The customer  18  or user  18  does not need to rely on a publisher  26  or other third party to write, create, design, and/or choose the material that serves as the digital content (as shown in the traditional publishing process in  FIG. 3 ). Instead, the user  18  is enabled to select and provide the digital content. 
     In a exemplary embodiment of the publishing method of the present invention, the digital content is readily modifiable by the user  18  or other individual  18 . It is dynamic, not fixed, such that it can be customized for the individual user  18  of the interactive hybrid printed material  10 . 
     Digital content may include audio content, video content, text content, picture content, graphic content, mathematics content, scientific content, sign language content, animation content, email content and/or Internet content or any other content file. 
     The apparatuses, uses, and methods disclosed herein have been described without reference to specific hardware. However, the apparatuses, uses, and methods disclosed herein have been described in a manner sufficient to enable persons of ordinary skill in the art to readily adapt commercially available hardware as may be needed to reduce any of the embodiments of the present invention to practice without undue experimentation. 
     Following from the above description and invention summaries, it should be apparent to persons of ordinary skill in the art that, while the methods and apparatuses herein described constitute exemplary embodiments of the present invention, it is to be understood that the inventions contained herein are not limited to the above precise embodiments and that changes may be made without departing from the scope of the invention as defined by the claims.
