SONAR

Sonar is a web‑based audiovisual interactive artwork, which employs a rule‑based system to generate multimodal artifacts. A collection of testimonies (poems, diary entries, interviews) from several writers describing the Carnation Revolution, and the end of a dictatorship, is used as the source text of this generative work.

 

As is often the case with technology, a sonar is a surveillance and detection technique initially developed for military purposes. In this work, however, similar devices will be used to track testimonies about the revolution which took place on the 25th April 1974 in Portugal. This sonar detects markers which become temporarily highlighted (in the form of geo-referenced markers) during the scanning sonar’s 360° sweep in a submerged world. A multimodal representation combining typographic and visual elements, as well as a sound file containing the testimony, is then triggered by the user. In order to create this work, a thorough research was conducted to recover the words of several writers and artists who have witnessed this period of change. Sonar not only allows us to preserve the memory of an important moment in the history of Portugal, but also demonstrates how digital media and electronic literature can be used to voice social concerns. Sonar is available here.
