Claim Text:
1. A computer-implemented method performed in connection with a computerized system comprising a processing unit, a memory and a projector, the computer-implemented method comprising: a. receiving an image data, the image data comprising at least a color value for each of a plurality of pixels of an image, the color value representing a color of said each of the plurality of image pixels, wherein each of the plurality of image pixels is characterized by pixel coordinates; b. causing the projector to project a temporal light signal to create a projection of the image on a projection surface; c. encoding the temporal projector light signal, for each pixel of the projected image, with an information segment comprising the pixel coordinates of the each image pixel of the plurality of image pixels; d. additionally encoding the temporal projector light signal with a color compensation segment configured to reproduce substantially the color of said each image pixel of the plurality of image pixels on the projection surface, wherein the information segment and the color compensation segment are time-multiplexed within the temporal projector light signal; and e. detecting the temporal light signal using a mobile device positioned within an illumination field of the projector and determining a position of the mobile device based on the detected temporal light signal, wherein the temporal projector light signal is a visible light signal.
