Abstract

Many interfaces have been designed to prevent or reduce
errors. These interfaces may, in fact, reduce the error rate
of specific error classes, but may also have unintended
consequences. In this paper, we show a series of studies
where a better interface did not reduce the number of errors
but instead shifted errors from one error class (omissions)
to another error class (perseverations). We also show that
having access to progress tracking (a progress bar) does not
reduce the number of errors. We propose and demonstrate
a solution – a predictive error system – that reduces errors
based on the error class, not on the type of interface.
