We explore how to augment/modify paper by modification of optical properties of paper (e.g. through application of inks or paper perforation) and manipulation of light (e.g. generated by tablet computers underneath the paper). In our work with paper interfaces: i) We show how to modify the appearance of printed content and create the illusion of making static objects perceptually dynamic, ii) We explore how to integrate multiple layers of information into paper in order to enable novel paper based interactions and iii) We designed a new hybrid stylus to enable direct interaction with paper, tablet displays or both.
