Method and system for self addressed information display
First Claim
Patent Images
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.

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.

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. - View Dependent Claims (11)

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. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
