你見過WiFi的樣子嗎 英學生繪製炫酷訊號圖
Luis, who is studying for a PhD in Architecture and Interaction Design, said he is fascinated with the idea of being able to see the hidden wireless networks which surround us.
建築與互動設計專業的博士生路易斯·赫南想出了一個讓我們周圍的無線網路視覺化的點子，併為之著迷。'I call the images "spectres" because wireless networks remind me of ghosts,' he said. 'They are there but you can't see them with the human eye.
他說：“我把這些圖片叫做‘幽靈’，因為無線網路讓我想起幽靈——它們就在那兒卻不能被肉眼看見。”'The fact we are becoming increasingly reliant on something that we can't see intrigues me. I wanted to find a way to show the wireless which is around us and also to show how it changes.
“我們越來越依賴於不可見的東西，這事兒激起了我的好奇。我想找到一種方法來顯示我們身邊的無線以及它的變化。”
Hernan created the photographs using a custom-made instrument designed to reveal them.
赫爾南用自制的裝置將無線網路顯示在相片中。It scans continuously for wireless networks, and transforms the signal strength to colour LEDs.
這臺裝置不斷掃描無線網路，並用彩色LED表示不同的訊號強度。The results are multi-coloured streaks of light which twirl and wrap in spaces, showing how they surround objects and people.
得出的結果是旋轉纏繞的彩色光線條紋，顯示出它們是如何存在於物體和人體周圍的。Hernan has also created an app which can be downloaded for free, for Android devices called Kirlian, which allows people to see the strength of Wi-Fi around them.
赫南寫了一個名叫Kirlian的安卓軟體讓人們看到身邊Wi-Fi訊號的強弱。該軟體可以被免費下載。He said: 'I would love other people to get involved and to create their own images using the app.
他說：“我希望其他人也能參與進來，用這個軟體創造出他們自己的影象。”'I used it as part of an exhibition of my work, where we hung mobile phones from the ceiling and it showed how signal strength was varying as people moved around the room.'
“我將這個軟體做為我的作品展的一部分。我們把手機懸掛在房頂上，用這個軟體展示當人們在房間裡走動時訊號強度是如何變化的。”
