ICT課程中一向有Virtual RealityW的介紹,而隨著iPhoneWAndroidW電話的流行,Augmented RealityW(港譯:增強實境)成為網絡的新寵兒,它是實時地將電腦畫像、聲音、氣味等融入於現實地界之中,有關的apps如雨後春筍,園丁google和wiki了一番,整理了一些資料介紹:

Wiki的定義:

Augmented realityW (AR) is a term for a live direct or indirect view of a physical real-world environment whose elements are merged with-, or augmented by virtual computer-generated imagery – creating a mixed reality.

MMdays 中Augmented Reality定義

Augmented Reality的研究至少也有十幾年了。根據A survey of Augmented Reality這篇1997年paper的定義,Augmented Reality有三個要素:

  1. Combines real and virtual 〈結合虛擬與現實〉
  2. Interactive in real time〈即時互動〉
  3. Registered in 3-D〈3D定位〉

要達到Augmented Reality的虛實結合,使用者必定得透過某種裝置來觀看。早先大部分的研究主要是透過HMD〈Head-Mounted Display;就是頭罩式的裝置〉,技術大概分成光學式〈Optical〉與影像〈Video〉兩種,前者是一種透明的裝置〈像是柯南的眼鏡之類〉,使用者可以直接透過這層看到真實世界的影像,然後會有一些另外的投影裝置把虛擬影像投射在這層透明裝置上。另外一種是不透明裝置,使用者看到的是由電腦處理好、已經虛實結合的影像。

最近幾年開始流行起來的smart phone,改變了augmented reality的樣貌。頭戴式的HMD還是太麻煩了,而smart phone同時具備電腦計算能力、錄影、影像顯示,還有GPS、網路連線、觸控、傾斜度偵測等等的額外功能,價格也逐漸平民化,於是在smart phone為平台的augmented reality研究越來越多。
