Fiducial markers and computer vision software provide a low cost and flexible way for human-computer interaction. Using the high reliability and minimal image pixel requirements of the ARTag fiducial marker system we are able to identify users and perform control actions with a simple small printed pattern. We describe two novel applications. Firstly, a user giving a presentation can control the slides with simple motions of a small printed marker towards their laptop or portable computer's built-in camera, thus replacing a remote or the necessity to step back towards the computer to advance the slides. Secondly, patterns printed on a small card can be used to interact with a kiosk, an example is the back of a ID badge used to bring up the schedule and direction information to a conference attendee.
