abstract:
This is a collaboration developed by elevenplay×Rhizomatiks who has been the pursuing possibilities of relationship and interaction between the body and technology by interacting with a variety of hardware and devices such as robot arms and motor-controlled floating balls. In this new work, objects are arranged three-dimensionally in real space through a tracking technology and drone control system, and the work, in which dancers give performances, has been presented so as to find the possibility of a new bodily expression. 

context:
With the development of video and image analysis technologies, trials to deal with the body as data and to expand the body have been conducted using such methods as Virtual Reality and Augmented Reality. One problem was, for instance, that a dancer had to wear a head mounted display or while looking at images on a projector. Since an intuitive approach is still difficult, a new experimental work employing advanced control and analysis technologies is required. As there is a limit to the output of images, it is necessary to use physical devices and objects so as to expand bodily expression presented in real space.

performance:
A system in which dancers can physically and more intuitively perceive the relationship between the body and data through computer-controlled drones has been developed. There are two kinds of drone movements: a motion produced by tracking a dancer's movements and an artificial motion operated on the software. At first, dancers had to be trained to interact with the drones because they could not predict how they would move, but eventually they were able to dance with the drones as closely as 10cm away from them.

system installation: 
Cameras with the motion capture system are used for the position analysis of the drones, 10 to 15 of which are needed. They are installed on the ceiling with a camera mount, or set up around the stage using tall tripods. Three retro reflective markers are attached to each drone so as to identify the position and angle. (See the figure for details.)

system hardware:
Using the position information of the drones, tracked by the motion capture system, the positions of three drones are controlled through feedback control. AscTec Hummingbird 2012 is used for the drones. In order to cope with problematic situations, manual operation is available at anytime; so if the tracking system has a problem, the drones can be landed automatically and safely.

system software:
Flight patterns have been created through various methods, e.g. producing them with original software, importing data from CG software, and using Ableton Live. For the analysis of the dancers' movements, the conventional method is used with retro reflective markers attached to them and motion capture cameras. We adopted a method in which these data are recorded, or captured in real time, processed, and played back so that the drones move according to the dancers' movements.  

three-dimensional object:
A quadrangular pyramid-shaped object is attached to the upper part of each drone for better visual confirmation. In the beginning, a sphere-shaped object was used, but it was difficult to confirm the drone's spinning movements visually. That is why an object of another shape was used. While motion is restricted due to greater air resistance, a quadrangular pyramid-shaped object was attached in order to improve expression and secure dancers' safety.

physical motion:
The dance shows the beauty and difficulty which come from resistance to gravity and inertia. Viewers are able to appreciate this naturally through their experience, and the same thing applies to the drones. The limits, motion dynamism, and a locus that is impossible to make with CG are produced by physical laws such as gravity, inertia and air resistance. Though the three-dimensional object was originally attached to improve visibility, it eventually played not only the role of making drones look bigger but also became an important element in emphasizing the motion and visualization of the interaction between the dancers and the laws of physics. 

projection:
As a step further, a projection was sometimes conducted for the object attached to the drone in order to improve visibility. While the system functions, the content has potential for further development. The work will be continually updated in the future.

ELEVENPLAY x RZM "fly"  (dance with drones)

Die japanische Tanztruppe [Eleven Play](http://elevenplay.net/index.html) hat sich mit Künstler, Hacker und Ikonoklast [Daito Manabe](http://www.daito.ws/en) zusammengetan. Gemeinsam haben sie eine Performance auf die Beine gestellt, welche die &#x201e;Rebellion der Maschinen&#x201c; auf ein ganz neues Level hebt.

Man nehme drei Tänzer, vier mit Pyramiden geschmückte Quadrokopter-Drohnen und eine durch Projection Mapping erstellte Kulisse. Die so entstandene Aufführung in der [Spiral Hall](http://www.spiral.co.jp/en/) von Tokio ist furchteinflößend.

Die Tänzer beten zu den Drohnen und werden von ihnen gejagt. Die Tänzer beten zu den Drohnen und werden von ihnen gejagt. Wie Gespenster erscheinen sie am Horizont, der immer näherzurücken scheint. Am Ende der Performance haben die Drohnen alle Tänzer von der Bühne verdrängt.

Seht hier einige GIFs, die [Prosthetic Knowledge](http://prostheticknowledge.tumblr.com/) von Eleven Plays und Daito Manabes Drohnen-Performance gemacht haben.
