Abstract

A user interface concept for wireless ad hoc content sharing between portable devices referred to as portable content containers (PCCs). A user-centered design approach is provided enabling users to share content such as music and photos. A variety of physical ways of establishing a secure connections between the PCC devices is provided. In addition, a clear view on the location of the content stored on the devices, and a drag & drop interface is provided. Use is made of separate spaces, each containing the corresponding content and includes a “shared” space such that all connected users may transfer content to and from to their own personal devices. The use of a drag & drop interface in combination with the subdivision of the screen into several spaces, provided the user with a clear view on the content location. The close proximity of users is assumed and enhances social interaction.

Claims

1. A system for ad hoc sharing of content stored in portable devices, said system comprising:

a) a means for establishing a communications link to connect a single portable device to one or more other portable devices;

b) means for generating a visualized shared space on a display area of each portable device of a connected user for facilitating content exchange between connected users via established communications links; and

c) means for enabling each individual connected user to control transfer of content to and from that user'"'"'s portable device via said communications link in response to manipulation of items representing user content in said shared space.

2. The system as claimed in claim 1, wherein said display area comprises a user space for displaying items representing content stored in said portable device, wherein a copy of said content is available for transfer to a connected user by moving an item representing said content from said user space to said shared space, said moved item being displayed in a shared space on each connected user'"'"'s device.

3. The system as claimed in claim 2, wherein a copy of said content is transferred from a transferor device to a transferee device via an established communications link in response to moving an item representing said content from said shared space to said user space of a transferee device.

4. The system as claimed in claim 1, further comprising means for indicating to a user a status of being connected during which time content items can be freely exchanged between portable devices of all connected users.

5. The system as claimed in claim 4, whereby said means for establishing a communications link further includes means for enabling secure encrypted communications.

6. The system as claimed in claim 5, whereby said means for establishing a communications link with a connecting user is by wireless RF communications.

7. The system as claimed in claim 5, whereby said means for establishing a communications link with a connecting user is by Infrared communications.

8. The system as claimed in claim 5, whereby a communications link connecting a single portable device to one or more other devices is established when said devices are in close distance range to each another.

9. The system as claimed in claim 8, whereby a communications link becomes automatically disconnected when said devices are out of communication range from each another.

10. The system as claimed in claim 5, whereby a communications link connecting a single portable device to another device is established when said devices contact each other, wherein content may be transferred between devices while in said contact.

11. The system as claimed in claim 5, whereby a communications link connecting a single portable device to another device is established when said devices are positioned one on top of another, wherein content may be transferred between devices while in said on top position.

12. The system as claimed in claim 5, whereby a communications link connecting a single portable device to another device is established when said devices are first in close proximity and in motion relative to one another, wherein content may be transferred between devices while in said motion.

13. The system as claimed in claim 5, further including means for generating a space in said display area on a transferee portable device indicating content included in a transferor portable device, said transferee user being enabled to transfer content from said transferor portable device to said shared space via said transferee device.

14. The system as claimed in claim 4, wherein said means indicating status of a user includes means for generating a graphic for display to indicate the presence and identity of a connected user and providing indication of whether content is or is not provided by said connected user in said shared space.

15. The system as claimed in claim 12, further including means for providing visual indication for identifying content in said shared space owned by a particular connected user.

16. The system as claimed in claim 15, wherein said visual indication is a color indication.

17. The system as claimed in claim 12, further including means enabling switching display of content items in said portable device according to graphic or textual views.

18. The system as claimed in claim 14, further including means providing metadata information associated with content items displayed in said display area.

19. The system as claimed in claim 14, wherein said shared space of a user'"'"'s device is populated with items already in said shared space as placed by other users upon connection.

20. The system as claimed in claim 14, wherein said content items associated with a first user are removed from the shared area of a connected user'"'"'s portable device when the first user'"'"'s communications Link is disconnected.

21. A method for ad hoc sharing of content stored in portable devices, said method comprising steps of:

a) establishing a communications link to connect a single portable device to one or more other portable devices;

b) generating a visualized shared space on a display area of each portable device of a connected user for facilitating content exchange between connected users via established communications links; and

c) enabling each individual connected user to control transfer of content to and from that user'"'"'s portable device via said communications link in response to manipulation of items representing user content in said shared space.

22. The method as claimed in claim 21, wherein said display area comprises a user space for displaying items representing content stored in said portable device, said step c) of controlling transfer comprising:

moving an item representing said content from said user space to said shared space for making a copy of said content available for transfer to a connected user, said moved item being displayed in a shared space on each connected user'"'"'s device.

23. The method as claimed in claim 22, wherein said step c) of controlling transfer comprises:

moving an item representing said content from said shared space to said user space of a transferee device and initiating transfer of a copy of said content from a transferor device to a transferee device via an established communications link in response to.

24. The method as claimed in claim 21, further comprising the step of indicating to a user a status of being connected during which time content items can be freely exchanged between portable devices of all connected users.
