Mouse and trackball controls
This section includes mice, trackballs or joysticks with features that may enhance ease of use such as chunky controls, visual and tactile feedback.
Trackballs are operated by rolling the ball on top using fingers, thumbs, palms or even feet. When the pointer is where the user requires it, a button can be pressed without the need to keep the mouse still.
Joysticks work similarly to wheelchair controls, the mouse pointer will move fastest when the joystick is pushed fully in a certain direction.
Some of the mice, joysticks, and trackballs in this section have sockets for the use of additional switches so the pointer/cursor can be positioned by the mouse and then a separate switch (which can be positioned to suit the user) can be pressed for the click. Mice use can also be adapted with the use of appropriate software. DLF Data does not list software, for details of software contact/visit the website of Ability Net www.abilitynet.org.uk, or the Oats Project www.oatsoft.org (for free open source software).
