Abstract

Methods and apparatuses for rapidly tagging and recalling (via direct pointing) metadata from moving or still images are described herein. In one embodiment, data having full descriptions and hyperlinks are tagged to specific objects in moving images and the invisible hyperlinks move dynamically to continually track the associated object. In one embodiment, a pointing device can be used to point to objects in the scene, whether moving or stationary, and by appropriate action such as clicking or activating a button, be able to substantially immediately recall part or all of the metadata content that pertains to the object. Other methods and apparatuses are also described.

Claims

1. A computer implemented method, comprising:

associating metadata with an object of a media stream having one or more frames, the metadata having information describing the object, including a location of the object within each frame;

dynamically tracking a pointed to location of a pointing device having a free-space multi-dimensional absolute pointer when a particular frame of the media stream is displayed; and

in response to an activation of the pointing device when the pointed to location of the pointing device is within a predetermined proximity of the object, retrieving and presenting the information from the metadata associated with the object.

2. The method of claim 1, further comprising providing metadata for the object for each frame of the media stream prior to displaying the media stream, wherein the metadata is invisible to a viewer of the media stream.

3. The method of claim 2, wherein the media stream comprises a digital movie.

4. The method of claim 1, wherein the metadata of the object further includes a hyperlink which when the activation of the pointing device is detected, additional information is retrieved and displayed from a remote facility via the hyperlink.

5. The method of claim 4, wherein the metadata of the object further comprises a description about the object and a cost to purchase the object from the remote facility.

6. The method of claim 5, wherein the metadata of the object comprises multiple hyperlinks and wherein different information is retrieved from multiple remote facilities via the hyperlinks to enable a viewer to compare the retrieved information.

7. The method of claim 1, further comprising determining the coordinates of the pointing device based on an orientation and/or location of the pointing device with respect to one or more reference markers located at a fixed location with respect to the display area.

8. The method of claim 7, wherein the pointing device includes a pixelated sensor and a wireless transceiver wirelessly communicating with a receiver that is connected to the display, and wherein the pointing device calculates its orientation and/or location based on information from the pixelated sensor.

9. The method of claim 8, wherein the pointing device wirelessly transmits the calculated orientation and/or location to the receiver to enable a controller coupled to the receiver to determine an absolute location pointed to by the pointing device within the display area.

10. A machine-readable medium having instructions stored therein, which when executed by a processor, cause the processor perform a method, the method comprising:

associating metadata with an object of a media stream having one or more frames, the metadata having information describing the object, including a location of the object within each frame;

dynamically tracking a pointed to location of a pointing device having a free-space multi-dimensional absolute pointer when a particular frame of the media stream is displayed; and

in response to an activation of the pointing device when the pointed to location of the pointing device is within a predetermined proximity of the object, retrieving and presenting the information from the metadata associated with the object.

11. The machine-readable medium of claim 10, wherein the method further comprises providing metadata for the object for each frame of the media stream prior to displaying the media stream, wherein the metadata is invisible to a viewer of the media stream.

12. The machine-readable medium of claim 11, wherein the media stream comprises a digital movie.

13. The machine-readable medium of claim 10, wherein the metadata of the object further includes a hyperlink which when the activation of the pointing device is detected, additional information is retrieved and displayed from a remote facility via the hyperlink.

14. The machine-readable medium of claim 13, wherein the metadata of the object further comprises a description about the object and a cost to purchase the object from the remote facility.

15. The machine-readable medium of claim 14, wherein the metadata of the object comprises multiple hyperlinks and wherein different information is retrieved from multiple remote facilities via the hyperlinks to enable a viewer to compare the retrieved information.

16. The machine-readable medium of claim 10, wherein the method further comprises determining the coordinates of the pointing device based on an orientation and/or location of the pointing device with respect to one or more reference markers located at a fixed location with respect to the display area.

17. The machine-readable medium of claim 16, wherein the pointing device includes a pixelated sensor and a wireless transceiver wirelessly communicating with a receiver that is connected to the display, and wherein the pointing device calculates its orientation and/or location based on information from the pixelated sensor.

18. The machine-readable medium of claim 17, wherein the pointing device wirelessly transmits the calculated orientation and/or location to the receiver to enable a controller coupled to the receiver to determine an absolute location pointed to by the pointing device within the display area.

19. A data processing system, comprising:

a processor; and

a memory for storing instructions, which when executed from the memory, cause the processor to perform a method, the method including

associating metadata with an object of a media stream having one or more frames, the metadata having information describing the object, including a location of the object within each frame,

dynamically tracking a pointed to location of a pointing device having a free-space multi-dimensional absolute pointer when a particular frame of the media stream is displayed, and

in response to an activation of the pointing device when the pointed to location of the pointing device is within a predetermined proximity of the object, retrieving and presenting the information from the metadata associated with the object.

20. The system of claim 19, wherein the method further comprises providing metadata for the object for each frame of the media stream prior to displaying the media stream, wherein the metadata is invisible to a viewer of the media stream.
