Recent developments in text-entry error rate measurement

ABSTRACT

Previously, we defined robust and easy-to-calculate error metrics for text entry research. Herein, we announce a software implementation of this error analysis technique. We build on previous work, by introducing two new metrics, and we extend error rate analyses to high key-stroke-per-character entry techniques, such as Multi-Tap.
