the third performance using arduino was probably the one where i got closest to my vision of an open work. with the buttons in K.ONTROL and DEMOCRACY it is still a very rigid setting, just allowing a certain option at a certain time but no fluent or organic interactivity.

HA | SHARING BREATH (2011) was an interactive performance installation exploring breath as a core life essence. audience’s heart beats and breath rhythms were monitored and instantly transfered into a a visual breathing of the space and a living sound scape. a dancer improvised to those shared sounds – sharing his breath as well. i see HA | SHARING BREATH as an attempt to make the invisble tangible. (video link)

the performance was created for an intimate audience setting with three audience members being hooked up: two of them had a breath sensor belt around their chest and one an infrared pulse sensor. through an arduino those values were brought into max/msp. at the beginning of the performance these sensors were calibrated and then would trigger and manipulate sounds according to the audience’s breathing patterns and pulse rate. the pulse would always be the beat, a sub-bass, whereas both breathing sensors would trigger different harmonics, evolving over time. the performance itself was ten minutes long, but the installation as a whole could be visited throughout the day. more info on the performance can be found on the HA | SHARING BREATH website.

again amy and craig worked on this one, here mainly on hardware and getting the signal into max/msp. jason, the sound designer, has done the programming in max as well as all the sounds for it. he has got an image of the max patch on his website. thanks guys.

a second performance i did using arduino was DEMOCRACY in 2011. it had a similar setup tech-wise to K.ONTROL, however the whole thing on a completely different scale. it took place in the new zealand parliament and had a cast of a member of parliament, a political scientist, a political journalist, a child, and (as the only ‘real’ actor) someone playing the cartoon figure ‘orange man’ who wants to encourage people to vote in ads before elections.

30 audience members would sit in a semi-circle in the former upper house of parliament and have a controller each with three push buttons. throughout the show they could vote for what they wanted to see on stage in terms of themes and also voice their opinions in polls. we would skip through different topics and performance sections in this manner, followed by an always lively discussion in the end about the political system. you can find more info about DEMOCRACY on its website.

the hardware setup was pretty similar to the one used in K.ONTROL, however all the thirty controllers were connected to one processor that would pre-calculate it and just sent 1, 2 or 3 (corresponding to the button pressed) for each controller into an arduino mega. coding was done in flash as i can remember, because this allowed better visual effects for the projection. basically there was always a question projected on screen, followed by a certain amount of time to vote, and then the results in bar or pie charts.

i am very grateful that i had such an amazingly skilled team for this. hardware was constructed by neill and michael, and coding done by amy and craig.

unfortunately i cannot post more images than these from rehearsals and construction phase for now as i haven’t secured the rights yet with new zealand parliament.

time to post something about my performance projects that used physical computing. i aim to create interactive performances that come close to the idea of an open work: meaning an artistic work that is open to be manipulated by the audience receiving it, to be altered, and therefore partly or fully created by the viewer. also i am interested in creating emersive environments, in which form and content go hand in hand. so far i have realised three performance installations that used arduino, but in which i did not do the technical side of it but rather was directing the performance. the first one was back 2009 as my major piece of the first year of studying theatre directing: K.ONTROL.

K.ONTROL was based on franz kafka’s novel the trial and set up as a reactive performance installation. audience members did log into a computer system before entering the performance space and then were randomly chosen by the computer to control the actors. they would go to their control panels in front of the audience where they had a controller with four push buttons. by pushing those they would trigger the actors to perform certain patterns: monologue, movement pattern, scene, chorus. the idea was that the notion of power and control over others, the feeling of not being able to influence anything and enforced conformity – which is constantly present in the novel of kafka – would be expressed through the technical aspect of the performance; the computer instance as a metaphor for the LAW which can never be reached or talked to by the protagonist k., the random selection of people who would willingly support the system. you can find more info about the performance on the K.ONTROL website.

hardware-wise the setup was pretty simple… three controllers with four push buttons, wired to an arduino. coding was done in processing and outputting a video signal to a projector (opening and closing doors according to which button was pressed) as well as sounds (giving commands to the actors). hardware and programming was done in an incredibly short time period by amy and craig.

custom controllers

DEMOCRACY controllera controller based on the great construction work of michael l. ;-) we used 30 of those for the interactive performance DEMOCRACY in 2011 and michael had done amazing work putting them together. it has got three push buttons which I already re-used in a couple of projects (see following posts: led controller, birthday canon machine).
controller with switch, push button and potentiometer

based on this controller i build my own by adding two new items: one on/off switch and one potentiometer. that controller now entails three basic control mechanisms (two digital, one analogue) in one device to play around with.

below is the prototyping bread board setup to make it work with arduino.
