ABSTRACT
This chapter discusses the alternative access and mounting solutions. Direct selection is where the Augmentative and Alternative Communication (AAC) user can select a desired button or cell without the need for scanning. Indirect selection is where switches are used with scanning. Direct selection methods include pressing buttons on a keyboard or cells on a touchscreen; selecting a cell with a mouse, trackball, joystick, glide-pad; or using a head-pointer, head-mouse or eye-gaze. Different cursors are designed for children with visual processing difficulties who struggle to see a standard cursor on the screen. Eye-gaze is usually used as an output method, to control what is happening on a screen. Switches offer a whole world of opportunity for users with a wide range of physical, sensory and cognitive skills. Mounting ensures that the device and accessories are positioned in consistent positions to minimize the physical effort required to operate the AAC system, and to maximize the user's sensory and motor abilities.
