Dasher is a free alternative text-entry system designed for computer users who are unable to use a two-handed keyboard. It is highly suitable for individuals with limited or no hand mobility. Dasher can be driven using a mouse, a trackpad, a touchscreen, a rollerball, or a joystick – any two-dimensional pointing device that can take over the role of a mouse. A foot mouse and a head mouse are additional options. It can also be driven using an eyetracker, giving a completely-hands-free writing system.
