The Double Skin/Double Mind Interactive Installation
The interactive installation Double Skin/Double Mind is a virtual version of the Double Skin/Double Mind workshop. This workshop, which has been taught by dance company Emio Greco | PC since 1996, represents the basis of the creative work of choreographers Emio Greco and Pieter C. Scholten. Participants in this workshop are challenged to discover new interpretations of their dancing body.
Throughout 2006 an interdisciplinary research group, consisting of dance notators Eliane Mirzabekiantz and Marion Bastien, motion capture researcher Frédéric Bevilacqua, cognitive neuroscientist Corinne Jola, media artist Chris Ziegler, cinematographer Maite Bermudez, artistic researcher Scott deLahunta and EG | PC researcher Bertha Bermudez, focused on this specific workshop, trying to analyse and document it.
Different data from each research area were collected, and interactive graphic visualisation tools and motion capture implemented to create the interactive installation Double Skin/Double Mind. After its first test with dance professionals in the rich environment provided by Tanzplan, the interactive installation was developed further. With a particular focus on its use in professional dance education, the two-year collaborative, interdisciplinary research project, Inside Movement Knowledge, looked into new methods for the documentation, transmission and preservation of contemporary choreographic and dance knowledge. Currently the project is in its last phase of development and planned to be part of the year curriculum at the Amsterdam High School of the Arts, Modern Dance Department during the coming 3 years.
The interactive installation
The Double Skin/Double Mind interactive installation offers participants the possibility to take part in a virtual version of the workshop in real time, while receiving verbal, physical and peripheral information.
In the Double Skin/Double Mind interactive installation, an environment designed by Chris Ziegler (ZKM Karlsruhe) surrounds the participant, consisting of an aluminum frame construction with one projection screen, four sound speakers and one tracking camera. The movement-tracking program Gesture Follower developed by Frédéric Bevilacqua (IRCAM) compares the data of the filmed version of the workshop with the real time data of the participant’s movements. As result of this comparison different feedback will be given through an interface lay out that Chris Ziegler has developed. Through the terminological and movement analysis of the main chapters of the workshop (breathing, jumping, expanding and reducing), dance researcher Bertha Bermudez, together with Emio Greco and Pieter Scholten, has developed a glossary where most relevant concepts are defined. This glossary has been used within the research process as basic information for each discipline providing the main movement principles and qualities needed to create the interactive environment for transmission, the installation Double Skin/Double Mind.
Sonification, visualization and music accompany the experience of participants as they mentally and physically travel through the Double Skin/Double Mind structure and learn what the different demands of the workshop are. By following a life size-moving figure, the participants recognize, compare and understand their actions and involvement in the practice of this workshop.
Defined by the research team during its development phase as 'an adaptation of the Double Skin/Double Mind workshop where participants can receive verbal instructions, visual and sonic feedback' the development of the interactive installation Double Skin/Double Mind departs from the research questions the interdisciplinary research project (Capturing) Intention was based on: What is it exactly that we do in our attempts at capturing dance? How do we deal with its ephemeral nature? Which are the existing systems for its documentation? How do these systems deal with qualities and intentions? And even more importantly: which disciplines can help us understand the knowledge that is dance? 
It is important to mention that some of these questions arise from the nature of the workshop Double Skin/Double Mind. This workshop focuses on qualities and intentions related to the form and execution of movements as well as on the idea of transfer; the process of transmission where main embodied concepts are passed from choreographer to dancer, or dancer to dancer, and in this case also to non dancers. With the workshop's specific qualities, intentions and modes of transmission providing the departure point for the installation development, the need to question and adapt all involved elements (software, tracking systems, design and interactive modes) became essential. To achieve an awareness of embodiment the installation had to focus particulary on the question: how can motion capture, new media interface design and gesture analysis be used when looking at more qualitative elements than to quantitative parameters?
The installation environment, where workshop structures and feedback responses could be experienced, was conceived of as a space that could challenge motion tracking and quantitative analysis tools with principles related to qualities and states proposed by the workshop, such as:
Breathing.- Dialogue between inner body and outside space
Jumping.- Multiplication of the body.
Expanding.- Penetrating the space and lengthening the body
Reducing.- Incorporation of length and lines produced during expanding together
These previous examples from an early phase of development, are the result of thinking from and for different perspectives around the execution and analysis of dance. Trying to find common ground between language, physical experience and the sharing of expertise, the whole research process has been an achievement in the understanding of the other. The specific focus on four simple movement qualities versus a more general view of dance, allowed the research team to be very precise in their findings and proposals, while opening up ideas for future methodologies with more general purposes. On a different level, the developments made in relation to the field of dance education are still an open area, where much work remains to be done in understanding the use and function of such objects, within the studio and pedagogical curriculum of dance schools. As final reflection, the need for a long phase of categorization, definition and share parametrization of movement qualities has shown that the project's importance lies in its ability to to create common knowledge, language and ideas for the design, computarization and analysis of dance.
