Abstract
Typing on touchscreens is improved by dynamically and automatically positioning the desired home-row keys of an onscreen keyboard below the user's fingers while their fingers are hovering above the surface, thus reducing the need for the user to look at the onscreen keyboard while typing. The location of each of the user's fingers while hovering and/or resting is monitored. Correlation between the hover sensor data and touch sensor data increases the confidence level by which the system can determine which of the user's fingers were used to select a key. By determining which finger was used to make the selection, the system accurately disambiguates which letter the user intended to type.
