Content sharing methods and systems
First Claim
1. A portable device comprising a processor coupled to a memory and to a projector, the memory including instructions executed by the processor to enable the portable device to project items of content using the projector, the memory further including instructions executed by the processor to store data corresponding to projected items of content in a data log, said data log serving to identify historical content projected by the portable device, wherein the data log includes first and second data, the first data identifying content obtained by the device from a remote computer device, and the second data identifying content not obtained by the device from a remote computer device, and wherein the memory further includes instructions executed by the processor to encode a plural-bit steganographic digital watermark payload into at least certain of said projected items of content, said payload identifying the portable device.

Abstract
A first device (such as a cell phone) is equipped with a micro-projector, and used to present imagery on a display surface. A second device (such as a second cell phone) is equipped with a digital camera, and used to capture some of the projected imagery. The captured imagery allows a user of the second device to access digital content of interest from a user of the first device, or from elsewhere. The content may be visual, or of other form (content examples include audio, games, maps, text documents, video, spreadsheets, etc.). In one particular arrangement, the projected imagery is encoded with digital watermark data. Through such arrangements, one user can readily share content, and also engage in collaborative activities—such as cooperative game play, with one or more other users.

3. A non-transitory computer readable medium having instructions stored thereon that, if executed by a projector-equipped device, cause the device to perform operations including:
-
receive a first item of content captured using a camera portion of said device, or created in accordance with instructions of a user; receive a second item of visual content from a remote computer device; encode a plural-bit steganographic digital watermark payload into at least one of the items of content, said payload identifying the device; project the first and second items of content; and store data corresponding to the projected first and second items of content in a data log, said data log serving to identify historical content projected by the projector-equipped device. - View Dependent Claims (4, 5, 6, 7, 8, 9)

10. A method comprising:
-
encoding a plural-bit steganographic digital watermark payload into image data using a processor in a cell phone, the payload identifying the cell phone; and projecting the encoded image data onto a display surface, using an optical projector in said cell phone, said projecting comprising projecting plural items of content for display from the cell phone projector, one of said projected items comprising first imagery corresponding to image data obtained by the cell phone from a remote computer device, another of said projected items comprising second imagery that does not correspond to image data obtained by the cell phone from a remote computer device, at least one of said first or second items of imagery comprising said image data processed by said encoding act; and storing data corresponding to both of said items in a data log, said data log serving to identify historical content projected from the cell phone. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method comprising the acts:
-
encoding a plural-bit steganographic digital watermark payload into image data using a processor in a cell phone, the payload identifying the cell phone; and projecting the encoded image data onto a display surface, using an optical projector in said cell phone; wherein; said encoding comprises encoding said plural-bit steganographic digital watermark payload into first and second items of content; and said projecting comprises projecting the encoded first and second items of image data onto the display surface using said optical projector in the cell phone; and wherein the method further comprises; storing data corresponding to both of said first and second items of content in a data log, said data log serving to identify historical content projected from the cell phone; wherein the first item of content corresponds to image data obtained by the cell phone from a remote computer device, and the second item of content does not correspond to image data obtained by the cell phone from a remote computer device. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
