To illustrate this topic, the ergonomic qualities of the computerised voting system used currently in Brazil were evaluated. In the first stage, an ergonomic inspection of the device revealed problems of usability among a population considered able to utilise the new technologies.

A statistical analysis of the voting results in recent elections confirm the detected ergonomic problems, as well as their impact on that portion of the population, considered to have a normal relationship with the new computer and communication technologies.
