Long-Term Study of a Software Keyboard That Places Keys at Positions of Fingers and Their Surroundings

摘要

In this paper, we present a software keyboard called Ley-board that enables users to type faster. Leyboard makes typing easier by placing keys at the positions of fingers and their surroundings. To this end, Leyboard automatically adjusts its key positions and sizes to users' hands. This design allows users to type faster and more accurately than using ordinary software keyboards, the keys of which are unperceptive. We have implemented a prototype and have performed a long-term user study. The study has proved the usefulness of Leyboard and its pros and cons.
