Abstract
A system and method are directed to managing text input. An image of a virtual keyboard is displayed to a user. The user enters text by using the virtual keyboard image and an input device, such as a pointing device. The image is repeatedly altered, such as by position, size, angle, or shape. One technique includes altering the image after each selection of a virtual key is made. One aspect of the invention includes determining sensitive input fields within a page and facilitating the use of the virtual keyboard for those fields. The invention can be used to improve security when the possibility of keyboard sniffers exists.
