以實體化的資訊串流，連結觀眾與台灣各地即時的空氣汙染狀態，並用空間中的光影、體感與視聽經驗，反映空污物質的流動性。
我以Processing程式即時擷取台灣政府開放資料庫的空氣汙染數據(http://opendata2.epa.gov.tw/AQI.json)，每10分鐘更新資料，確保觀眾所見為即時狀態。台灣總共有84個空氣汙染觀測站，我先給予每一個觀測站一個色相(Hue)，再讓當地之空氣品質影響其呈現之色彩—若當地之空氣懸浮微粒數據(PM10、PM2.5)愈高，則色彩之明度(Brightness)愈低；若當地之氣狀汙染物數據(CO、NO2、SO2、O3)愈高，則色彩之彩度(Saturation)愈低。換而言之，空氣品質愈糟，此站點呈現出的色彩愈髒濁。
前方投影幕以四層雷射切割之壓克力片組構、懸吊，造型為人體肺泡造型，形成具深度與立體感的結構。觀眾所選擇的空汙站點數據，會轉譯為色彩投放到此造型上。觀眾也可以選擇「呈現所有城市」，來投放出整體色彩的流動狀態。
在互動方式上，簡化為單一旋鈕控制介面，讓小朋友也可以體驗參與，提升經驗趣味，也提升空汙議題被討論的可能。整合空間情境設計、數據映射與電子控制，來呈現台灣關鍵的空汙議題，暗喻各個城市之間的關係應該更緊密，以共同合議台灣整體空污改善的解決方案。

By materializing the invisible streams of environmental data, Field of Smog (2021) connects viewers with the real-time air pollution status across Taiwan. Through the interplay of light, shadow, embodied sensation, and audiovisual experience, the installation reveals the fluid and dynamic nature of airborne pollutants.
Using Processing, I retrieve live Air Quality Index (AQI) data from Taiwan’s governmental open database (was at: http://opendata2.epa.gov.tw/AQI.json and is now moved to: https://data.gov.tw/dataset/40448), updating every ten minutes to ensure the displayed information reflects real-time conditions. There are eighty-four air quality monitoring stations throughout Taiwan. Each station is assigned a fixed hue (H), while its color representation changes according to local air quality: higher concentrations of suspended particulates (PM10, PM2.5) decrease brightness (B), and higher levels of gaseous pollutants (CO, NO₂, SO₂, O₃) reduce saturation (S). In other words, the worse the air quality, the duller and murkier the color at that location appears.
The front projection surface is composed of four layers of laser-cut acrylic sheets suspended in space, forming a structure reminiscent of human alveoli. The color data from the selected air monitoring station is projected onto this layered form. Viewers may also choose to visualize “all cities,” displaying the collective flow of air quality conditions across Taiwan.
Interaction is simplified to a single rotary controller, allowing even children to participate easily and intuitively. This design not only enhances engagement but also encourages public dialogue around air pollution. By integrating spatial design, data visualization, and electronic control, Flow presents Taiwan’s critical air pollution issues while metaphorically suggesting that cities must remain interconnected—collaboratively seeking comprehensive solutions for cleaner air.
