Visually navigating ants can determine their home vector solely from the panoramic image they see. We have also shown that as long as the scene is robust, it overrides the path integration vector they have. Furthermore, our experiments indicate that ants make directional decisions based on the momentary panorama alone and do not keep track of the route already travelled.
Such behaviour can be explained by the use of the image difference function to determine the home vector from the scene. However, to experimentally test that theory, we need to be able to manipulate the scenery. To do that, we built a virtual reality arena optimised for ant vision which we call Antarium. We are at the early stages of experimenting with it, but we have already seen some promising results.

Post-scriptum :

M. Kocsi got a masters from electronic engineering in 1985 at the Technical
University of Budapest, Hungary. He then moved to Australia in 1990 and
worked for various R&D companies. In 1995 he founded Bendor Research
Pty. Ltd., a small R&D firm and developed embedded
systems. In 2013 he started a part-time PhD under the
supervision of Prof. Jochen Zeil at the ANU on the topic of visual navigation of ants.
