Adding Overlays
Raghav Sood · Apress eBooks · 2012
As mentioned before, augmented reality (AR) is the overlaying of data that is related to the direct or indirect camera preview being displayed. In the majority of AR apps, the camera preview is first scanned for markers. In the translator kind of apps, the preview is scanned for text. And in some gaming apps, no scanning is done; instead, characters, buttons, text, and so on are overlaid on the preview. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
