Usability testing (focusing on computer sensible people)
Results
4 out of 16 electors were not able to vote simply at all;
5 out of 16 electors cast "residual" vote only (spoiled and incomplete vote).
A "blindly stream" strategy employed by most of people who failed to vote:
during interaction they focused all their attention only at the keyboard and the screen was simply ignored. When considered separately, the information on the keyboard, as well as on the screen, could not support the complete voting process. Indeed, without looking at the screen it is very difficult to understand what it needs to be confirmed.
