Touch scan-n-search: a touchscreen interface to retrieve online versions of scanned documents

ABSTRACT

The system described in this paper attempts to tackle the problem of finding online content based on paper documents through an intuitive touchscreen interface designed for modern scanners and multifunction printers. Touch Scan-n-Search allows the user to select elements of a scanned document (e.g. a newspaper article) and to seamlessly connect to common web search services in order to retrieve the online version of the document along with related content. This is achieved by automatically extracting keyphrases from text elements in the document (obtained by OCR) and creating "tappable" GUI widgets to allow the user to control and fine-tune the search requests. The retrieved content can then be printed, sent, or used to compose new documents.
