Calculating Metrics

Once all letter and function keys are defined, the user can calculate performance metrics for the analyzed keypad. Selecting Calculate from the Metrics menu presents a dialog. It displays calculation progress and allows the user to cancel the process.

The KSPC tab presents keystrokes-per-character values and ambiguous word frequency.

The WPM tab presents the words-per-minute prediction and thumb usage statistics.

The Ambiguous Sets tab lists ambiguous word sets -- words whose letters map to the same keys.

The Keystroke Data tab displays each entry in the word-frequency file with its associated keystrokes for the analyzed keypad.

Pressing the Copy Panel button copies the contents of the selected tab to the system's clipboard. The contents can then be pasted into other applications for analysis or re-formatting.
