Joystick

A joystick is an input device with a lever that tilts in multiple directions to control cursor movement on screen, used as an alternative pointing device by people with motor impairments who have difficulty using a standard mouse. Adaptive joysticks come in various forms — some are small enough to be operated by a finger or chin, while others are larger for palm or fist operation. Joysticks are particularly useful for people with limited fine motor control, as they require less precise movements than a mouse or trackball. However, joystick users may struggle with accuracy when targeting small interactive elements on web pages, making adequately sized click targets and virtual cursor enhancements important accessibility considerations.
