There was a report on electronic voting irregularities in South Carolina (during the Republican primaries last week) this morning on NPR. The person that was interviewed,a representative of the State Election Commission, naively stated that the machines were fine, but it was the users who were not following operating procedures. Here is a quote:
“Any voting system is dependent on its user following the proper operating procedures and, in this case, Horry County election officials missed a step,” he says. That step was closing out tests performed on the machines before the elections, which left some test votes still recorded and any affected machine locked up.
Unfortunately, this widespread view of blaming the user prevents designers and engineers from coming up with easier to use voting machines. If the problem lies with the user, the manufacturer/designer is off the hook in terms of fixing the problem.
From a user-centered design perspective (which has roots in human factors), you never blame the user! With the prevalence of voting system usability issues in the news, clearly, there are no usability or human factors people working within the manufacturers of electronic voting systems.

However, there is some hope. Human factors researchers Tiffany Jastrzembski and Neil Charness, at Florida State University, examined electronic voting machines to improve accuracy among older adults. The article, published in Ergonomics in Design, is a good example of applying the science of human factors to human-machine problems.
