Abstract

A system and method are described for creation of a mosaic display system. A device is assigned an address which may be used to produce unique sequence of illumination which is based on a code determined by the address. A sequence of images of a number of devices may be used to determine a spatial location associated with a device address.

Claims

1. A method for displaying information comprising:

assigning an address to a display element;

causing display elements to produce a temporal pattern of illumination;

acquiring a sequence of images including illumination produced by two or more of the display elements;

determining a spatial location and a timing offset associated with the address based on the sequence of images;

assigning the temporal pattern to a device located at pre-determined spatial coordinates; and

determining a scale factor for converting pixel positions to physical distance units based on detection of the device in the sequence of images.

2. The method of claim 1 further comprising:

creating the temporal pattern based on the address.

3. The method of claim 1 further comprising:

including varying color information in the temporal pattern based on the address assigned to the display element.

4. The method of claim 1 further comprising:

including a wireless device in the display elements.

5. The method of claim 1 further comprising:

including an LCD device in the display elements.

6. The method of claim 1 further comprising:

including a light emitting device in the display elements.

7. The method of claim 1 further comprising:

including a device capable of playing a media file in the display elements; and

creating a portion of the temporal pattern associated with the address by playing the media file on the device.

8. The method of claim 1 further comprising:

acquiring a portion of the sequence of images using a device comprising the display element.

9. The method of claim 1 further comprising:

creating a spatial pattern based on the address and causing the display element to produce the spatial pattern as a part of the temporal pattern of illumination.

10. A system comprising:

display devices producing a temporal pattern of illumination;

a display device producing a pattern of illumination based on an address assigned to the display device; and

a server receiving image sequences including illumination produced by two or more display elements, and determining a spatial location and a timing offset associated with the display device based on an image sequence wherein the timing offset is an absolute time relative to a real time clock, assigning the temporal pattern to a device located at pre-determined spatial coordinates; and

determining a scale factor for converting pixel positions to physical distance units based on detection of the device in the sequence of images.

11. The system of claim 10 further comprising:

the display device acquiring a portion of the image sequence and initiating the pattern of illumination based on a start condition determined based on the image sequences.

12. A non-transitory computer readable storage medium storing therein a program for causing a computer to execute an operation comprising:

assigning an address to a display element;

causing display elements to produce a temporal pattern of illumination;

acquiring a sequence of images including illumination produced by a display of a mobile communication device as the display element among the display elements;

determining a spatial location and an absolute time base offset associated with the mobile communication device and a target image based on the sequence of images,

assigning the temporal pattern to a device located at pre-determined spatial coordinates; and

determining a scale factor for converting pixel positions to physical distance units based on detection of the device in the sequence of images.

13. The storage medium of claim 12 wherein the operation further comprises:

including temporal variations in luminance and hue in the illumination produced by the display of the mobile communication device based on the address; and

determining the timing offset based on a comparison of the illumination produced by the mobile communication device to that produced based on addresses of the display elements.

14. The storage medium of claim 12 wherein the operation further comprises:

causing the display elements to acquire absolute time information from server devices prior to causing the display elements to produce the temporal pattern of illumination.

15. The storage medium of claim 12 wherein the operation further comprises:

obtaining the sequence of images from a plurality of imaging devices;

determining whether an illumination sequence associated with the address is detected in images produced by more than one imaging device; and

determining three dimensional spatial coordinates and angular information regarding the display of the mobile device based on the imaging devices in which the illumination sequence is detected.

16. The storage medium of claim 12 wherein the operation further comprises:

assigning addresses to the display elements based on a software application downloaded by the display elements;

obtaining a set of physical coordinates associated with light sources which may be imaged in the sequence of images;

initiating the temporal pattern of illumination based on a start condition detected by the software application resident on the display elements; and

determining a physical coordinate associated with the display based on the set of physical coordinates associated with the light sources.

17. The storage medium of claim 16 wherein the operation further comprises:

causing the light sources to generate a unique predetermined temporal sequence.

18. The storage medium of claim 12 wherein the operation further comprises:

mapping a pattern to spatial locations and temporal offsets associated with the display elements; and

causing the display elements to reproduce a temporal and spatial pattern determined by the pattern and the display elements.

19. The storage medium of claim 12 wherein the operation further comprises:

mapping a pattern to spatial locations and temporal offsets associated with the display elements; and

delivering a media file and a start condition to the display elements based on the pattern and the display elements.
