This application was designed to track specially designed fiducial markers. You will find the default "amoeba" fiducial set within the document "default.pdf" within the symbols folder. Print this document and attach the labels to any object you want to track. The default fiducial tracking engine is using Ross Bencina's fidtrack library which is basically a newer high-performance implementation of Enrico Costanza's d-touch concept. Alternatively you can use the "classic" or the "dtouch" sets. See below how to configure the application using these older symbol sets.
