Extending keyboard adaptability: An investigation

Abstract.

One common typing error is the overlap error, in which two keys are pressed at once. The existing keyboard accessibility filters do not directly address overlap errors. Several techniques for automatic correction of overlap errors are compared in an offline analysis. Leveraging keystroke timing characteristics is shown to achieve a 50% to 75% reduction in errors for study participants with relatively high error rates. A simple heuristic for estimating the accuracy improvement for an individual using this filter is presented and considerations for live implementation and further work are discussed.
