PACER is a novel augmented-reality-like cell phone interface that is optimized for fine-grained paper document interaction. In contrast to the existing limited point-and-click interaction with pre-defined hotspots on paper, PACER allows users to issue rich hybrid camera-touch gestures to select arbitrary paper document details (e.g. individual Latin words, Chinese/Japanese characters, math symbols, places on a map and any image regions), and to specify actions to be applied to the selected content.
