Trackballs- A ball is housed in a stationary base and can be rotated; student has limited ROM and good fine motor.

Joysticks- Game joystick converted into mouse little movement; student with limited control of fingers and hands.

Head-pointing-monitor tracks student head movement from signal on a wearable device; students cannot use their hands for a mouse.

Eye-Gaze- The movement of a student’s eyes direct the mouse; student with no reliable muscle movement.
