Abstract

This paper presents a new pressure-based error prevention technique for mobile touchscreen text entry. Two user studies were conducted to compare the new technique with a conventional virtual keyboard, one with novice and another with expert users. Results of the first user study showed that with practice the new technique significantly improves accuracy. Yet, no such indication was observed during the second study.
