第十四章 體感網路之道
透過幾台電腦或機器人裝置來延伸你的認知，只不過是起步而已，以之為基礎，接下來
將會有更多更廣的互動機會，能夠讓數百千計的裝置互相溝通，幫助我們找到遺失物、
追蹤醫院裡病人的情況、改善交通壅塞、或是提高田地的農作物產量。讓各種裝置、設
備、機器人連接在一起，互相傳遞資訊並溝通，將會形成一套巨大無比的系統。
裝置互連
想像一下，世界各地任何地方都有小小的裝置收集各種資料，儲存供後續追蹤、分析、
以及投射廣告。若推到極處，這就是物聯網的願景，由資料與裝置交織而成的網路，結
果是能夠取得關於整個世界的完整資訊。
除了擷取資料（來自裝置與機器人的輸入），物聯網還提供了新型態的「輸出」系統，
提供美化特製的環境感知體驗。
知名例子之一是氣候預報燈（見圖 14-2）（

），從網
路抓取天氣資訊，以視覺化動態手法，呈現天氣預報。

另一個例子是無人駕駛飛行載具，知道如何根據線上資料庫，辨識並避開障礙物。
擁有網際網路連線能力的產品，也會塑造出新型態的居家生活（會讓人立即想到
Amazon 的 Dash 按鈕）。智慧家庭將會包括能夠感知一切的裝置，從誰在家、誰不在
家，一直到冰箱裡蛋的數量，然後根據所得資訊執行適當的動作。
