Abstract

HotPaper enables users to electronically interact with paper documents by pointing their camera phones at a document. Electronic interaction is in the form of reading and/or writing images, audio and video clips, urls, notes, etc to the paper. HotPaper does not require any machine readable code, such as a barcode or watermark, to be present on the document. It utilizes our Brick Wall Coding document recognition algorithm [1] that uses a small document patch image to retrieve electronic versions of documents without performing OCR. The HotPaper demonstration runs on a Treo 700w 312 MHz mobile phone and performs document recognition at 4 frames per second using 176x144 video input.
