People wonder how I operate my Macintosh and Windows computers. While sitting in a wheelchair at my desk, I do my graphic and web designs by manipulating a Kensington ExpertMouse trackball on the floor with my right foot. Also, in order to type on a regular keyboard, I use a headstylus. On my Mac, I wouldn’t be able to work without the “Universal Access“ (AKA: Easy Access) sticky keys, which allows me to hold down more than one key at a time. On Windows, I use the “Accessibility Options” sticky keys, which is similar to “Universal Access” sticky keys. When no one is present to put my headstylus on me, I use KeyStrokes by AssistiveWare in conjunction with my trackball. KeyStrokes is a fully-functional advanced virtual on-screen keyboard that allows you to type with a mouse, trackball, head pointer or other mouse emulator to type characters into any standard Macintosh application (www.assistiveware.com/keystrokes.php).
