Abstract

A system and method for automatic relevance-base sharing information between handheld devices are provided. A centralized location stores interest profiles of a plurality of users of handheld devices. A profile agent and a sharing agent in a computing device obtain, from the centralized location, a list of users with profiles similar to the profile of a user operating the computing device and mark sharable items of such user with users to whom the item is relevant. The synchronizer synchronizes the list and the marked sharable items to the handheld device of the user operating the computing device. The logic embedded in the handheld device allows automatic relevance-based sharing of items between the handheld device and other handheld devices.

synchronizing the list and the marked sharable items to the user'"'"'s handheld device; and

providing automatic relevance-based sharing of items, including the sharable item, between the handheld device of the user and another handheld device, wherein the sharing may be initiated by the handheld device of the user or the other handheld device.

2. The method of claim 1, wherein if the user is a recipient of a sharing session initiated by the other handheld device, a query is made into the synchronized list to see if the user of the other handheld device has similar interest.

3. The method of claim 1, wherein if the user is a sender of a sharing session initiated by the other handheld device, a query is made into the synchronized marked sharable items for items relevant to the user of the other handheld device.

4. The method of claim 1, wherein the handheld devices are systems with low processing power as compared to a personal computer.

5. The method of claim 1, further comprising providing a user interface mechanism on the user'"'"'s handheld device that allows the user to initiate sharing either as a recipient or a sender.

6. The method of claim 1, further comprising providing a user interface front end to the list and the marked sharable items that allows the user to modify them, set their own list and marked sharable items, or set the rules for making the list and marked sharable items.

7. A system for automatic relevance-base sharing information between handheld devices, comprising:

a centralized location that stores interest profiles of a plurality of users of handheld devices;

13. The system of claim 12, further comprising a user interface front end to the share information database that allows the user operating the computing device to modify information stored in the share information database, set his/her own information, or set rules for the profile agent or the sharing agent.

15. The method of claim 14, wherein the share information database is created in and synchronized from a computing device operated by the sender.

16. The method of claim 14, wherein the marked sharable items is included in an item interest table, the item interest table including an item identification field for denoting sharable items, a user identification field for denoting users to whom the sharable items are relevant, and an interest level field for indicating the interest level of the users in the sharable items.

17. The method of claim 14, further comprising beaming a portion of the share information database corresponding to the beamed item to the handheld device of the recipient.

19. The method of claim 18, wherein the intent to beam relevant item is symbolized by a relevant item being received, the relevant item being the subsequent item accepted.

20. The method of claim 18, wherein the share information database is created in and synchronized from a computing device operated by the recipient.

21. The method of claim 18, further comprising receiving an intent to share relevant item from the handheld device of the sender, wherein the query is performed after the handheld device of the recipient receives and acknowledges such intent.

22. The method of claim 18, further comprising prompting the recipient for guidance if it is determined that the sender does not have similar interests.

23. The method of claim 18, wherein the list of users is included in a similar user table, the similar user table including a user identification field for denoting users with profiles similar to that of the recipient and a similarity score filed for indicating the degree of similarity between each user'"'"'s profile and the recipient'"'"'s profile.

25. The computer readable medium of claim 24, wherein the share information database is created in and synchronized from a computing device operated by the sender.

26.
