Mobile pointing and input system using active marker

Abstract

We present a mobile pointing and input system for mobile phones with minimal hardware parts that allows users who wear an eyeglass display to view and interact with a large virtual image. To use the mobile phone as a pointing and input device, a fiducial marker-based tracking system developed for augmented reality is adapted for our system. The brightness and shape of active marker could be changed according to the state of operating environment and/or the user's intentions in order to increase the detection rate of the marker.
