The Assistive Learning variant of the R60 Series desktop trackball has been adapted for users with impaired mobility / learning difficulties. The trackball includes a finger guard surrounding the three color-coded switches to provide guidance with activation. The R60 Assistive Learning is supplied with an injection moulded plastic case and color-coded switches which provide the conventional left, middle and right button functionality found in commercial trackballs/mice. The unit has been designed to be a freestanding desktop device and optimizes desk space when compared to a mouse.
