Inner’s Lair


Inner’s Lair started with a crazy idea of having an immersive interactive installation that could gather many artistic and computational topics that we at Artica have been disccussing in the last months. So, mostly we wanted to tryout our new conceptual implementation of cool topics as immersive sound, computer vision, interactive robotics, and organic behaviors.


Meanwhile POP UP Lisboa 2010 came up and I was invited to apply a purposal for an instalation, and I thought that Inner’ Lair could be a great challenge for me and André Almeida, and a great opportunity to promote ARTICA interactive and technological solutions.

So, all the conditions where in place, we have this great idea and a great place to show it. Due to the complexity of the project we assume that it would be shown as a WIP (work in progress). This way we stablished several steps, to setup sound, all the set, computer vision system and robotics.

We will be all the saturdays (except 27th, wich we will be there in 28th) working on-site until the end of Pop Up. After the end of the event we intend to continue this WIP on another place. If you know a place to show this creation we will be glad to know.

This saturday (13 of November) was really fun, we had a lot of friends passing by willing to give us a hand, lots of visitors asking what we where doing, we had such a good time.



This is the current state of Inner’s Lair, robots still don’t move, but they will ;)


ICU . I See You

ICU is a sub-project of the SWARS (see what a robot sees) project.

This time I not just wanted to see what a robot sees, but I also wanted to give the robot the ability to understand that there is a person in the room, and stare at the person.

To detect faces I used the OPENCV library for Processing, wich turns out to be very fun to work with and is very sensitive to human faces.. and sometimes it detect faces where there aren’t any.. maybe it is a ghost face detector algorythm!!

I didn’t have time to work with the four motors, I am only working with the two servo motors on the top. Next step will be to apply inverse kinematics and have a better level of interactivity.

Unfortunately I had to pick the computer that was being used in this installation, I will need it in the next weeks, but this bot will be available to the public very soon I promise!!

This is the code I am using if someone wants to look at it, you will need to have the MegaServo library installed for the Arduino sketch, and the OPENCV lib for the Processing sketch.

zezinho, the poser – interactive installation

This is the final result of the first stage of this project. An installation where zezinho calls for visitors and when a visitor reachs the mixing controllers he waits for new poses.

If you are nearby Lisbon, you can visit zezinho until 9 of July at:
FABRICA FEATURES Lisboa. Rua Garrett, nº83 | Megastore United Colors of Benetton, 4º andar | 1200-203 Lisboa


This was my final project at Restart in the course Digital Art and New Media.
It is an Immersive Sound Installation where the visitor is invited to interact with a cube and to use it to experience sound.

The sounds are a fusion between recorded samples of native and ritual sounds and songs (Didgeridoo´s, Djambes, Shamanic rituals, Portuguese Traditional Songs from Miranda do Douro) and real time sounds generated by software synthesizers created in MAX-MSP.

By touching the cube faces the visitor changes sound tracks and enables / disables sound effects. In real time a projection is created and returns a reference of the sounds being played, at the same time that the visitor´s hand position is analyzed beyond the cube thus changing equalization and triggering more sound effects. The cube color and the projection color change when new sounds are triggered.

Special thanks to Pedro Pestana, André Sier, André Gonçalves and to all my classmates  ;)
