This study investigates the effect common keyboard layoutshave physical effort. First, alphabetic keyboard layouts areexperimentally compared to the QWERTY layout. Second, the numberrow often found on QWERTY keyboards are experimentally comparedto numeric keypad layout. Our study shows that users operate moreeffectively using a QWERTY layout than an alphabetical layout.Moreover, users operate more effectively using a numeric keypadcompared to a row of number keys. Implications for two importantapplication areas in society, namely touch-based self-service kiosksand numeric input in context of Internet banking are discussed.
