HEAD POINTERS
Most head pointers protrude from the forehead and are held in place by adjustable straps. Other units protrude from the chin, which places the pointer more in line with the item being accessed. Chin pointers reduce the unsightly barrier imposed by the forehead pointers as they do not obscure as much of the wearer's face.
MOUTHSTICKS
Mouthsticks can be used by people with reasonable head and mouth control to access a range of devices including computer keyboards, electronic typewriters, and calculators. The ideal mouthpiece should allow the user to speak and to maintain saliva control, although these functions are not easy with the mouthpiece in place. Mouthsticks should be orthodontically correct to minimise wear on the teeth and maintain jaw alignment. A number of mouthsticks are available commercially, but in some cases a custom design is necessary.
STYLUSES
In computing, a stylus (or stylus pen) is a small pen-shaped instrument that is used to input commands to a computer screen, mobile device or graphics tablet. With touchscreen devices, a user places a stylus on the surface of the screen to draw or make selections by tapping the stylus on the screen.
