Referring to FIG. 3, handheld computer 310 may be capable of communicating with other electronic devices within a local area. For example, handheld computer 310 may be able to communicate with various other local devices such as, but not limited to, an individual's mobile telephone 320. Mobile telephone 320 may include a Bluetooth transceiver or other transceivers. Phone 320 may broadcast a unique identifier (ID) associated with phone 320. In another exemplary embodiment, a person's shoe 340 may include a wireless transceiver device such as a Bluetooth transceiver. Such a shoe may indicate any of a variety of information, such as, but not limited to, the wearer of the shoe, for example, or any other unique identifier. Further still, in an exemplary embodiment, a networking access point, such as a Bluetooth access point 330 may be in communication with handheld computer 310. Bluetooth access point 330 may be configured to broadcast a unique identifier. Further, access point 330 may be associated with a specific location, for example, access point 330 may be located in the handheld user's home or any other home, office, or building. In such a case, handheld computer 310 may associate access point 330 with not only the network to which it is connected but also to the location at which access point 330 is located. In further exemplary embodiments, any of a variety of other known objects or access points may include, but are not limited to, other computing devices having wireless communication capability, such as soda machines, other handheld computing devices, laptop computers, cellular telephones, local area network access points, automated teller machines (ATMs), etc.
Referring now to FIG. 1, a handheld computer or other portable electronic device 100 is depicted. Handheld computer 100 includes a processor 110 which may be any of a variety of conventional processing devices. A memory 120 is coupled to processor 110. Memory 120 may be any of a variety of memory devices including, but not limited to read only memory (ROM), random access memory (RAM), flash memory, etc. Memory 120 may be utilized to store programs running on processor 110, and/or may be used to store other types of information. A transceiver 130 is coupled to processor 110. Transceiver 130 may be any of a variety of wireless transceivers including, but not limited to RF or other electromagnetic transceiver devices, and/or infrared or ultrasonic devices, among others. In an exemplary embodiment, transceiver 130 includes an antenna 135 for transmitting and receiving communication signals. Handheld computer 100 also includes a display 140. Display 140 may be any of a variety of displays including, but not limited to an LCD touch screen display. Display 140 may be used to display information to a user of handheld computer 100. A database 150 may be stored on handheld computer 100. Database 150 may be stored in memory 120 or may be stored in any of a variety of other storage devices including peripheral devices such as a disk drive or memory card. Further, in an alternative embodiment, database 150 may be stored on a server computer which is accessed over a wireless communication link using transceiver 130.
Because of the portability and ease of use and access to handheld computer 100, it is often desirable for a user of handheld computer 100 to take and/or share notes about a particular person, place, and/or thing, and further to access these notes at a time when the known object, person, or item is present. In systems of the prior art, it is required that the user remember that such notes are available and, further, remembers how to access them. As wireless networking environments become even more data rich, this problem becomes more evident. In a data rich environment, the user of handheld computer 100 may be unaware of exactly what data is available on the portable device. Thus, a method to automatically pull up relevant data when a known object is nearby is desirable.
Referring again to FIG. 1, known objects 160, 170, and 180 may be in nearby proximity to handheld computer 100, such that they are in wireless communications with handheld computer 100. Information that is collected by handheld computer 100 or is input by a user of handheld computer 100 may be associated with a unique, detectable identifier, that is associated with each of individual objects 160, 170, and/or 180. The information that is collected or input relating to each object may be stored on handheld computer 100 and an association and/or relationship of the object to the data may be stored in database 150. In an alternative embodiment, the data and the association and/or relationship may be stored in database 150. There may be many ways to provide unique identifiers for objects encountered by handheld computer 100. For example, biometric information may be used about people, or location information about places and/or stationary objects. Further, known objects, people, or locations may be associated with a unique wireless identifier (for example, a Bluetooth device address or alias), that the known object may advertise or broadcast. In the case that objects 160, 170, and 180 are broadcasting unique identifiers or association signals, the handheld computer may then access database 150 and identify relationships between stored data on handheld computer 100 and the association signals being received. The data may then be indexed based on the relationships accessed in the database. Once the relevant data is indexed, the data may be prioritized based on any of a number of factors including, but not limited to distance from each of the objects, importance of the objects, etc. Once the data is prioritized, the relevant data may be retrieved from storage on handheld computer 100.
Referring now to FIG. 2, an exemplary process for associating and/or relating data with objects and accessing the data 200 is depicted. A handheld computer or other electronic portable device receives association signals (step 210). When association signals or object identifiers are received by the handheld computer, a database is accessed, the database including relationships between data sets and association signals or identifiers (step 220). Based on the relationships retrieved from the database, the data is indexed (step 230). In an alternative embodiment, the data may be prioritized based on the index and/or based on any of a variety of other types of information, including distance and/or location (step 240). Further, in an alternative embodiment, data is then accessed on a handheld computer by the user automatically based on the prioritization (step 250).
Referring again to FIG. 3, a user of handheld computer 310 may approach a person carrying a phone 320. As the person is approached, the phone broadcasts an identifier which is received by handheld computer 310. Handheld computer 310 associates the received signal with the particular person and accesses information about the person. For example, handheld computer 310 may access calendar information associated with the person such as, the person's birthday is today, or any of a variety of other messages or lists, etc.
