Dasher – keyboard-free text entry
Dasher is a kind of text input tool which lets someone write without using a keyboard.
Dasher lets you enter text on a screen using a pointing device such as a mouse, a touchpad, a touch screen, a roller ball or a joystick.
There is also an eye tracking version of Dasher which lets you write text as fast as normal handwriting.
