Usability of Code Voting Modalities

Internet voting has promising benefits, such as cost reduction, but it also introduces drawbacks: the computer, that is used for voting, learns the voter's choice. Code voting aims to protect the voter's choice by the introduction of voting codes that are listed on paper. To cast a vote, the voters need to provide the voting code belonging to their choice. The additional step influences the usability. We investigate three modalities for entering voting codes: manual, QR-codes and tangibles. The results show that QR-codes offer the best usability while tangibles are perceived as the most novel and fun.
