R. Wimmer, F. Echtler Exploring the Benefits of Fingernail Displays Extended Abstracts of CHI 2013, Paris, France. (bib)
	Fingers are an important interface both to the physical and the digital world. We propose research on artificial fingernails which contain tiny displays and sensors. These fingernail displays greatly supplement other input and output channels, offering novel interaction possibilities. We present three contributions: (1) the general concept and use cases for fingernail displays, (2) a technique for capturing touch events at the fingernails and interaction methods supported by this technique, and (3) an overview of relevant research questions.
