Systems and methods for time-multiplexing temporal pixel-location data and regular image projection for interactive projection

A system and method for generating a projected image signal encoded with position information. The temporal pixel-location data is hidden within visible light signal used for regular image projection. This enables the user to utilize one or multiple ring-shaped light receivers to implement touch or multi-touch functions on a regular image content generated using light from the same projector. The temporal light signal generated by the projector is sliced into multiple temporal segments. The segments include segments of two different types.

EMBEDDED MEDIA BARCODE LINKS AND SYSTEMS AND METHODS FOR GENERATING AND USING THEM

Embedded Media Barcode Links (EMBL), are optimally blended iconic barcode marks printed on paper documents that signify the existence of media associated with that part of the document. EMBLs are used for media retrieval with a camera phone. Users take a picture of an EMBL-signified document patch using a cell phone, and the media associated with the EMBL-signified document location is displayed on the phone.
