Abstract

Vibroacoustic sensing is a method to investigate and enable tangible interaction on surfaces. One of the main challenges in this field is to make a sheet of paper on a surface interactive without either prefabrication or permanent instrumentation. This research presents VibroAware, a novel system that makes paper on a surface interactive as is by leveraging vibrations. The sheet of paper becomes interactive when users attach it to four thin piezoelectric transducers. Users interact with the sheet of paper on the surface by touching or blowing, which produces vibrations captured by our system. In this research, an algorithm is developed to enable localization and adapt to environmental noise without requiring analyzing material properties. VibroAware offers users the ability to test and prototype faster, and create interfaces using vibroacoustic sensing on a sheet of paper more intuitively. This research presents a future vision for using vibroacoustic sensing to enable interaction on a sheet of paper that opens opportunities to utilize inherent material properties, such as vibration.
