ON REDIRECTING DOCUMENTS WITH A MOBILE CAMERA

Abstract

This paper presents a method for facilitating document
redirection in a physical environment via a mobile camera.
With this method, a user is able to move documents among
electronic devices, post a paper document to a selected
public display, or make a printout of a white board with
simple point-and-capture operations. More specifically, the
user can move a document from its source to a destination
by capturing a source image and a destination image in a
consecutive order. The system uses SIFT (Scale Invariant
Feature Transform) features of captured images to identify
the devices a user is pointing to, and issues corresponding
commands associated with identified devices. Unlike RF/IR
based remote controls, this method uses object visual
features as an all time ‘transmitter’ for many tasks, and
therefore is easy to deploy. We present experiments on
identifying three public displays and a document scanner in
a conference room for evaluation.
