Installation art

 Parqueando by Hector Centeno & Jorge Lozano

Modified remote controlled cars, sound and video

Three RC cars where retrofitted with microcontrollers (Arduino) and proximity sensors to allow them to have autonomous movement. The cars avoid obstacles but also present an erratic, quasi-animalistic movement behaviour while exploring the space. A speaker mounted on the car emits synthesized tones that change according to the proximity of the obstacles. Each car carries a video display showing a single video (by Jorge Lozano) divided in a triptych. The movement of the cars generates a sound and visual landscape within the space.

Presentations:
- El Parqueadero, mixed media art centre in Bogota, Colombia, November 2012, in the show "Error_ Origen no Encontrado" as part of the collective Entre_Activa.



Sound+Video Live Performances

 Bogota_2012

Improvised multichannel sound and generative video

30 minutes live performance at Plataforma Bogota (Arts, Science and Technology Lab) on November 23, 2012. A meditative exploration that combines urban and industrial sounds and images collected in Bogota, Toronto and NY. This is a binaural audio version of the 8 channels recorded live (headphones recommended for listening). The performance consisted of 8 speakers located around the audience and a frontal video projection. Soundscapes recorded in Bogota using an ambiosnic microphone where processed live and diffused through the speakers. The video projection was generated using realtime analysis of the sound to drive the movement and effects parameters. These excerpts are from the recorded sound and generated video that can also be presented as a fixed piece.

Excerpts:

The full audio from this performance can be listened here (binaural audio, headphones recommended):



 Tetsuo+Hector @ Supermarket

Improvised stereo sound and generative video

Live performance at The Supermarket in Toronto, May 15, 2012. A video by the Japanese radio artist Tetsuo Kogawa performing with two AM radio transmitter coils mixed live with generated video and audio using FM radio micro transmitters.

Technical work

These are samples of the art installations I've worked on designing the interactive components (electronic sensor circuits, sound systems, microcontroller programming, computer and mobile programming) and the sound design.

 Afectos Descentrados by Alexandra Gelis with Hector Centeno

Modified furniture, multichannel sound system and video

Interactive sound and video installation by Alexandra Gelis with electronics, programming and sound design by Hector Centeno. Repurposing and transforming pieces of furniture typical of the bars in the coffee production zones in Colombia, this installation allows the audience to improvise their own multichannel sound art piece. The control console allows to record sound samples and reproduce them and alter them using granulation effects while manually panning the sounds through a 6 channel speaker sound system. The performer can record their own performances, including the spatialization, and reproduce them later. Mac mini running Max/MSP, MIDI controllers, Arduino and LCD display, microphones, amplifiers, video monitor, audio interface and 6 speakers.

Premiere:
- El Parqueadero, mixed media art centre in Bogota, Colombia, November 2012, in the show "Error_ Origen no Encontrado" as part of the collective Entre_Activa.



 In the Woods by Alexandra Gelis with Hector Centeno

Sewing kit, sensors, sound transducers and Android tablet

Interactive video/sound installation by Alexandra Gelis, with electronics and programming by Hector Centeno. An old sewing kit box was retrofitted with IR sensors to detect the speed of movement of the spools. Each spool triggers a different video on the Android tablet and plays it at a frame rate controlled by the spool speed. This is a documentary piece that portrays the lives of the inhabitants of the "El Bosque" neighbourhood in Colombia. IR sensors, IOIO board and custom Android app.

Premiere:
- Gallery 1313, Toronto. Part of the show "Dystopias on Art and Technology". February-March 2013.



 Raspao by Alexandra Gelis with Hector Centeno

Custom made snow cone vending cart, multichannel sound system and video

Interactive sound and video installation by Alexandra Gelis with electronics, programming, sound design by Hector Centeno. Multichannel sound art interactive installation consisting of a custom made snow cone vending cart. Microphones and cameras pick up the surroundings and allow the audience to improvise and record their own sound art performances while snow cones are prepared and served. Mac mini running Max/MSP, MIDI controllers, Arduino and LCD display, microphones, amplifiers, video monitor, battery power, solar panel, audio interface and 6 speakers.

Premiere:
- Sound Travels Festival, New Adventures in Sound Art. Wychwood Barns, Toronto. Summer 2012.
