Abstract
Disclosed are devices and methods for rendering, on a display of a mobile communication device, digits and/or characters that may be more easily perceived by a visually impaired user. The display shows a selected digit or character by itself, taking up a substantial part of the display. In an embodiment, the digit or character may be rendered by the display so as to subtend at least 2 degrees of arc at a predetermined viewing distance. In another embodiment a touch screen may be used for digit or character entry. Depending on the portion of the touch screen that receives contact input from the user, a user can select a particular digit or character for entry. In this manner, the digit values could be presented to a visually impaired user, for example, for an account number for online banking, while retaining privacy.
