  • 2. CLASSIFICATION•  This work is part of the DualVote project•  Development of an pen and paper based eVoting System•  In DualVote, the voter uses a pen and paper to cast theirvote but during this process their vote is also recordedelectronically•  We became interested in expanding on the functionality ofDualVote so we decided to develop a feature basedclassification for voting machines
  • 3. SPECIFICATION OF INTERFACEFEATURES•  We looked at 26 commercial eVoting systemsworldwide•  We identified 5 broad categories of InterfaceFeatures•  Error-Feedback•  Ballot Confirmation•  Machine Activation•  Duality Generation•  Interface Modality•  We identified 14 distinct Interface Features in total
  • 4. JLP CLASSIFICATION•  We then ranked the 26 systems in a particular orderand assigned each machine classification number.•  We chose the traditional pen and paper method ofvoting as our ‘baseline’ and assigned this the lowestclassification number: JSN1
  • 5. JLP CLASSIFICATION•  We were interested primarily in incrementaldifferences in functionality between votingmachines•  A simple pen and paper voting method offers the least interms of functionality and allows us to compare commercialeVoting systems to same.•  This is useful when we are replacing a pen and paper systemwith an electronic one
  • 6. JLP CLASSIFICATION•  There are approximately 162 possible classifications(1-162)•  Systems with a low classification have more incommon with the basic functionality offered by asimple pen and paper method•  Systems with a higher classification have less incommon with pen and paper and offer morefunctionality
  • 7. FOR THE FUTURE?•  We have also documented the design decisionsrelating to how each Interface Feature has beenimplemented•  We would like to determine if a lower classificationnumber directly corresponds to a system whichrequires less user actions to cast a vote•  In this way, a system with a lower classification is also moreusable
