台英合作「Selected Ambient Airs 資料聲音化的共創實踐」

“Selected Ambient Airs” is a project that connects the environment, technology, and the arts by developing an environmental monitoring network and incorporating sonification practices. Hands-on activities allow participants to learn about open data, basic electronic circuits, and microcontrollers. By applying creative technologies, participants connect to the Internet, explore data, create music, and foster social interaction.

In an age of co-creation and connection, the concepts of making and playing effectively blur the line between creators and their audiences, encouraging more individuals to become creators themselves. Both elements are essential for establishing audience participation and nurturing the spirit of collaboration. Building on a series of resources developed across various disciplines, we aim to connect natural systems—specifically, weather and air quality—with compositional methods in generative media to address unseen phenomena and encompass scientific and emotional dimensions.

執行步驟 STEPS

STEP 1 – 物聯網環境感測 IoT Environmental Sensor

STEP 2 – 創造自己的開放資料 Create Your Own OpenData

利用樹莓派開發的環境感測模組，會將所搜集到的環境資料通過MQTT協定於Node-RED平台上發布。我們將能通過簡單的圖形化介面，把感測模組傳輸的數據創建為自己的資料集並開放給他人使用。換句話說，只要有網路，大家都可以下載本計劃中各節點的環境感測資料，也能依照我們所提供的規格來新增節點。

The environment sensor module collects and publishes data from its surroundings over MQTT in Node-RED. We can create a dataset from the environmental data transmitted by these sensor modules and provide access to others through a simple GUI interface. In other words, anyone can download the environmental monitoring data via the Internet and contribute a new node based on the given specifications.

STEP3 – 資料聲音化實驗 Sonification Experiments

「資料聲音化」是將資料以聲音再現的動作。環境感測模組所搜集來的環境數據，經由數位工具輔助對應到不同聲音參數。此一途徑奠基於許多既有系統與資源之上，使用者可自行選擇對應參數的方式，通過多方面交流觀點來促進合作對話。儘管某種程度上，這也是隨機性的展現，因為產出是附加且非刻意的，被觀測者並非有意要傳遞音樂給任何人。但這在概念層面卻很重要，「正在聆聽城市環境狀態」的想法，會改變你我體驗音樂的方式。

We begin with a sonification method that utilizes existing resources to connect various systems, aiming to facilitate cooperative conversations and encourage a mutual alteration of perspectives through the reflection and interpretation of complex rhythms. Conceptually, mapping numeric data to sound parameters introduces an element of randomness, as this music is incidental and unintentional. However, this aspect is significant at the conceptual level. The idea of “listening to our environment” may transform our perception of music.

「空氣的聲音」工作坊 ‘Sound of the Airs’ Workshop
Date： 2019/07/06 13:00 – 18:00 at Taipei Digital Art Center 

本場次與美術學科中心合作，參與者皆為大專院校、高中職教師。工作坊主要分為三個步驟：

1. 利用樹莓派來自製低成本IoT環境感測模組。
2. 將感測器所蒐集到的數據上傳至網路成為開放資料。
3. 利用環境資料來進行資料聲音化實驗。

1. 下載Node.JS來執行Node-RED https://nodejs.org
2. 可遠端登入樹莓派的VNC https://www.realvnc.com/en/raspberrypi/
3. 聲音編程軟體SuperCollider https://supercollider.github.io
