The Leiden Augmented Reality System (LARS)

Abstract

Most augmented reality toolkits require special markers to be used. In our system any designated object in the environment can be used instead of special markers. Furthermore, our system was designed to work with low contrast surfaces (such as the wrinkles on the hands of the users). We used a constellation of maximally discriminative salient points derived from the environment to position a 3D rendered entity. These salient features are combined with local texture to give greater detection stability which results in less jitter to the user. We present a real time system which has sufficiently low computational requirements that it works with typical hardware found on modern laptops, tablets, and smartphones.
