Abstract

See full text

An approach for modifying a size of a key on a keyboard displayed on a touch screen is presented. A fingertip of a user is determined to be aligned with the key or touch screen, and in response, the size of the key is enlarged by a first enlargement amount. Responsive to the fingertip moving closer to the key, a second, closer proximity of the fingertip to the key or touch screen is determined. The size of the key is further enlarged by a second enlargement amount to assist the user in touching the key and avoiding touching another, adjacent key on the keyboard.
