Abstract
Some individuals with reduced motor function rely on scanning keyboards to operate computers. A problem observed with scanning keyboards is that errors typically occur during the first group or first cell of a group. This paper proposes to reduce such errors by introducing longer dwell-times for the first element in scan sequences. The paper theoretically explores several designs and evaluates their effect on overall text entry performance.
