A novel text input for public displays and palmtop computers is presented that separates the input from the display of the edited text. While the public display shows both the edited text and a character generation interface, palmtop computers are used for input in a blind way, i.e. without the need to look at the palmtop's small screen. This allows for an effective text input with multiple users interacting simultaneously on the public display. Advanced features such as a dictionary-based word completion can run directly on the public display's computer instead of the palmtop with its limited resources.
