A Hybrid Touch Interface for Prêt à Voter

In this paper we propose a novel front-end for Prêt à Voter that aims to maintain the privacy and integrity guarantees found in the paper based version, whilst simultaneously improving the accessibility of Prêt à Voter. Namely, we maintain the Prêt à Voter property that no machine learns your vote, whilst providing improved accessibility. We term this new front-end Hybrid Touch and have implemented it on both a Microsoft Surface and a multi-touch screen. Hybrid Touch combines the privacy benefits of paper with the accessibility benefits of a touch screen. It is this combination that provides more accessibility opportunities as well as allowing Prêt à Voter to handle larger and more complicated elections. Our goal is to develop a single unified front-end, which can be easily augmented with additional accessibility technology, to provide the same core interface for both able-bodied and disabled voters.
