Communication Devices @ ÉCAL

Workshop

Lausanne, Switzerland, 2017

When I was giving a workshop at ÉCAL in Lausanne, Switzerland, I asked the students to come up with novel communication devices. Erika Marthins, Arthur Moscatelli, Pietro Alberti and Andrea Ramìrez Aburto built a color to smell translator which they called “Bouquet” within just one week!

A collection of different ways to communicate

The cone shaped device has an optical sensor built in its tip, with which it can recognize different colors. Inside the cone's bottom is a stepper motor controlled disc, that turns pads with according scents directly under the nose of the operator. If you'd point it to a red color for example, the disc would turn a cotton pad, which is soaked with strawberry aroma, to the device's smell opening.

The students found some great natural smells for the different colors. Representing blue turned out to be a bit of a challenge, though. At the end, they decided to translate it to the fresh artificial smell of a chemical “Blue Ocean” room fragrance, which was fitting very well.

To round up this brilliant work, they even designed a series of colorful posters with which everyone could try out their little synesthetic machine.

Special thanks

I want to thank ÉCAL and especially Prof. Cyril Diagne for inviting me, the students for their energy, excitement and good ideas and Laura Perrenoud and Marc Dubois for assisting in this workshop!
