Beaming into the rat world: enabling real-time intereaction between rat and human each at their own scale

Immersive virtual reality (IVR) typically generates the illusion in participants that they are in the displayed virtual scene where they can experience and interact in events as if they were really happening. Teleoperator (TO) systems place people at a remote physical destination embodied as a robotic device, and where typically participants have the sensation of being at the destination, with the ability to interact with entities there. In this paper, we show how to combine IVR and TO to allow a new class of application. The participant in the IVR is represented in the destination by a physical robot (TO) and simultaneously the remote place and entities within it are represented to the participant in the IVR. Hence, the IVR participant has a normal virtual reality experience, but where his or her actions and behaviour control the remote robot and can therefore have physical consequences. Here, we show how such a system can be deployed to allow a human and a rat to operate together, but the human interacting with the rat on a human scale, and the rat interacting with the human on the rat scale. The human is represented in a rat arena by a small robot that is slaved to the human"s movements, whereas the tracked rat is represented to the human in the virtual reality by a humanoid avatar. We describe the system and also a study that was designed to test whether humans can successfully play a game with the rat. The results show that the system functioned well and that the humans were able to interact with the rat to fulfil the tasks of the game. This system opens up the possibility of new applications in the life sciences involving participant observation of and interaction with animals but at human scale.

De l'interactivité du récit au récit interactif

À ses origines, la théorie du récit, notamment la narratologie d'inspiration formaliste et structuraliste, s'est développée dans le creuset des études littéraires. De ce fait, le point focal de cette discipline a longtemps été constitué par le récit verbal, généralement sous la forme d'un texte écrit et planifié par un auteur, laissant de côté les formes narratives émergentes, participatives ou interactives. On observe cependant, depuis une vingtaine d'année, une accélération dans le processus d'élargissement des objets d'étude de la narratologie, accompagnée par une mutation épistémologique. Retraçant cette évolution, Jan Christoph Meister observe ainsi un changement d'orientation faisant passer la théorie du récit de l'étude de phénomènes textuels à l'analyse « des fonctions cognitives de récits oraux et non littéraires, ouvrant ainsi un nouveau chapitre dans le projet narratologique » (2009 : 340). Si l'intrigue peut être décrite - en adoptant un point de vue fonctionnaliste et cognitiviste - comme une matrice de possibilités ontologiquement instable, comme un dispositif dont la fonction première est d'ouvrir des virtualités narratives et d'engendrer de la curiosité ou du suspense (Baroni 2007 ; 2009), alors il n'y a pas de raison de la considérer comme un obstacle à l'analyse de récits émergents et participatifs, voire de simulations ou de pratiques ludiques hautement interactives.

Plant sources of amazon rosewood oil

The aim of this study is to reevaluate the plant sources of the Amazon rosewood oil which have been named Aniba rosaeodora Ducke and Aniba duckei Kosterm. There is some disagreement on the exact botanical status of these species. Some Lauraceae specialists analyzing available material from both species concluded that there is no basis for regarding them as different. Based on our results we are confirming that the chemical composition of both species is quite different from that previously reported. So we are suggesting to bring back the previous botanical rosewood status as proposed by Adolph Ducke.
