Em3 is an interactive installation in which the public can contact the artist’s body through the mediation of the artwork. This installation is the final experiment of a theoretical and practical research conducted over two years, that investigated the relationship of bodies mediated by sensors in order to obtain my Master of Art title. On the occasion, the Microsoft Kinect 3D camera was used as a sensor due to it’s human movement recognition algorithm. The installation confronts artist’s and interactors bodies as scanned data in two projections. The first one presents graphics, generated from the relationship of the two bodies and are back projected on an one-way-mirror, so that the interactor can see them along with his/her reflection. The second one is the silhouette of the previously recorded artist’s body, which also reflects in the mirror. The graphics are updated from various parameters into dynamic visualizations styles. The main point is based on the comparing of artist’s and interactor’s bodies. In order to develop the artwork, a choreography was created and recorded out of poses and movements that the sensor response was different from what we would expect. The similarity or difference between these two bodies toggles between the two main visualization modes. If the installation consider the bodies in similar poses, their skeletons representations would appear, otherwise, we could see their joints moving in space, morphing into a mass as a collective body. The provocation is in the kind of movement made in the artist’s choreography. Some of the movements were made in a way that the sensor would not recognize, so that the machine can show new perceptions of our body. Therefore, even if the interactor tried to copy the virtual body, the comparison will not be stable, because the virtual body is not a copy of the human body as the interactor is used to. In fact, the virtual body is subordinated to the perception of artificial sensory system. Thus, the bodies joints are combined precisely because of its heterogeneity, emphasizing the difference of motion of the physical bodies, but also of human and machinic perception.
