Problem
Solution
The typewriter or computer keyboard, and the telephone keypad, have become so ubiquitous that they are, to most populations, the expected method of entering information, even when simulated by membrane pals or on a screen.
will stay that w? for the foreseeable future....
good input all about meeting expectations... see notes about kb layout, NANP, localization...
Variations
instead of variations, axes of variation, which can be combined. NOTE: Most devices will here multiple modes... see input mode pattern
Hardware / Virtual
keyboard / keypad
Direct / Multi-tap
Note that predictive systems, while associated with 10-key entry, can be uses with any input method, and is addressed in a separate pattern.
