A software system was designed and implemented using an integrated set of persuasive approaches to encourage healthy typing behaviors that are often recommended for combating Repetitive Strain Injury (RSI). The system encourages users to avoid excessive typing speeds, to set up and use typing shortcuts, and to take regular breaks from typing. The design and integration of a foot-operated input device that interoperates with the software system is also presented. Forty-three undergraduate students completed a laboratory procedure that used a between-groups experimental design to evaluate the effectiveness of the system at persuading users to avoid typing at speeds that exceed a defined threshold as well as at persuading users to use predefined keyboard shortcuts (for example typing cpt as a shortcut for captain). Results indicated that providing users with feedback when they exceeded a typing speed threshold decreased the number of times they exceeded that threshold. Similarly, results indicated that providing users with feedback when they missed an opportunity to use a typing shortcut decreased the total number of shortcut usage opportunities missed.
