Abstract
A chording input method on mobile phones, using two thumbs simultaneously, was examined. This paper addresses advantages and disadvantages in chording applied to text input and control using keypads of mobile phones. Chording can be a good input and control method in that it can provide more options with limited number of keys, and that it can provide mobile users with extended usability and functionality. The chording input method on a mobile keypad showed comparable performances in choice reaction times and error rates with conventional single keying method, even though certain chording seemed to cause troubles in finger coordination, resulting in longer reaction times and more errors.
