IHM et démocratie quand une machine à voter n'est pas utilisable par les seniors

The objective of this paper is to show the ergonomics of voting machines currently used in France and their problems they involve for older voters. Initially we do a quick assessment of problems that have posed so far the various voting systems and the problem of access to technology by older people. We compared the interface of one of these voting computers with a multimodal interface that we have created with some usability guidelines. This comparison was made with users tests carried out on 20 elderly users. The results show a significant exclusion of older people with the voting machine used in France and open a track to develop a computer to vote for those who could not vote under normal conditions.
