Welcome to Metazoa Ludens

What is Metazoa Ludens?

Metazoa means multicellular organism or animals.

Ludens come from the phrase Homo Ludens which means to play.

Putting them together, Metazoa Ludens means to play with animals.

Technological advancement has changed the way we do things, for example snail mail takes days to be delivered while email as brought forth by technology is almost instant.

Nevertheless there is not much new development for the ways humans interact with animals using advanced technology. With Metazoa Ludens, we hope that we could harness the powers of advanced technology and start new ways of interacting with animals.

Although animals and pets are so important for families and society, in modern urban lifestyles we can spend little time with our animal friends. Interactive media should be aimed to enhance not only human to human communication, but also human to animal communication. Thus, we promote a new type of inter-species media interaction which allows human users to interact and play with their small pet friends (in this case hamsters) remotely via the Internet through a mixed reality based game system "Metazoa Ludens". We scientifically examined the effectiveness of this system in a two pronged approach. Firstly, and most importantly the positive effects to the hamsters are ensured using Body Condition Score study. Secondly, the method of Duncan was used to assess the strength of preference of the hamsters towards Metazoa Ludens. Lastly, the effectiveness of this remote interaction with respect to the human users as a interactive gaming system with their pets/friends (hamster) was examined based on Csikszentmihalyi's Flow theory. Results of both studies inform of positive remote interaction between human user and their pet friends using our research system. This research is not aimed just at providing specific experimental results on the implemented research system, but is aimed as a wider lesson for human to animal interactive media. Thus also the lessons learned are extrapolated and detailed in this project as a framework in general for human to animal interaction systems.
