I posted these elsewhere, but I am unable to find them. As they belong in this topic, here they are again.

Screen shots of some Linux accessibility software that is available free either from the Ubuntu software site or Synaptic.

Dasher

A graphical predictive text input system
Dasher is an information-efficient text-entry interface, driven by natural
continuous pointing gestures. Dasher is a competitive text-entry system
wherever a full-size keyboard cannot be used - for example,

* on a palmtop computer
* on a wearable computer
* when operating a computer one-handed, by joystick, touchscreen, trackball,
or mouse
* when operating a computer with zero hands (i.e., by head-mouse or by
eyetracker).

The eyetracking version of Dasher allows an experienced user to write text
as fast as normal handwriting - 25 words per minute; using a mouse,
experienced users can write at 39 words per minute.

Dasher uses a more advanced prediction algorithm than the T9™ system
often used in mobile phones, making it sensitive to surrounding context.

Mousetrap

Head tracked mouse control

MouseTrap permits people with movements impairments to access the computer.
It uses image processing to translate the user's head movements into
mouse events (movements, clicks) which allow users to interact with
the different desktops managers and applications.

Easystroke

gesture recognition program

Easystroke is a gesture-recognition application for X11. It aims to be highly
configurable while at the same time providing an intuitive user interface. It
was designed with a Tablet PC in mind, but it also works well with a mouse.
